Plasmid-mediated gene transfer between insect-resident bacteria, Enterobacter cloacae, and plant-epiphytic bacteria, Erwinia herbicola, in guts of silkworm larvae.

Five strains of Enterobacter cloacae isolated from several species of plants and insects were able to grow in the guts of silkworm larvae. A much larger population of Ent. cloacae strains was detected in the insect guts and feces collected 3 and 6 days than in samples collected 1 day after feeding artificial diets contaminating these bacteria. Furthermore, insect-origin strains of Ent. cloacae were mated with a donor strain, epiphytic Erwinia herbicola, harboring RSF1010 and pBPW1::Tn7 plasmids in the insect guts by introducing these bacteria through separate artificial diets administered at different times. A number of transconjugants, Ent. cloacae strains which had acquired RSF1010 plasmid, were detected from guts and fecal samples at transfer frequencies of 10(-2) to 10(-3) per recipient. Thus, gene transfer between epiphytic Er. herbicola and insect-resident Ent. cloacae strains in the insect guts was confirmed. These findings may provide significant information about the role of "in insecta mating" in the evolution of these bacteria.

Multimedia article. Success of episioproctotomy for cloaca and rectovaginal fistula.

PURPOSE: Surgical repair of rectovaginal fistula with an advancement flap has had suboptimal results. The existing literature documenting episioproctotomy as a surgical option in females with rectovaginal fistula or cloaca is limited. This study was designed to examine our experience with episioproctotomy in this group. Additionally we were interested in risk factors, which might predict failure. METHODS: All females who had repair of a rectovaginal fistula or cloaca with episioproctotomy from 1998 to 2004 were studied. Data were collected from chart review and telephone contact. This included demographics, body mass index, tobacco use, Crohn's disease, previous surgery, and diverting stoma. RESULTS: Data were obtained from 42 females (mean age, 39.2 (range, 25-70) years). The mean follow-up was 37 (range, 2-84) months. Nine females had a cloaca and the rest had a rectovaginal fistula with an anterior sphincter defect. Eleven (all with anterior tissue) had recurrence of fistula. None with cloaca had recurrence. Eight of 11 recurrences occurred in females who had failed at least one previous repair. No variables that were studied significantly affected recurrence. Median (25th, 75th percentiles) postoperative Wexner incontinence scores for those with and without recurrence were 8 (7, 12) and 5 (2, 6) respectively. CONCLUSIONS: Episioproctotomy is a successful technique for repair of rectovaginal fistula and cloaca. Incontinence score postoperatively were acceptable. It should be considered a first line of surgical treatment in those with a fistula that includes compromise of the anterior sphincter complex.

Specificity of enterobacterial repetitive intergenic consensus and repetitive extragenic palindromic polymerase chain reaction for the detection of clonality within the Enterobacter cloacae complex.

An increasing number of clonal outbreaks caused by members of the E. cloacae complex is being reported. For the detection of clonality, pulsed-field gel electrophoresis (PFGE) is considered the golden standard, but PCR-based methods are cheaper, easier to perform, and provide faster results. One hundred ninety-five isolates of the E. cloacae complex isolated at the university hospital Grosshadern, Munich, Germany, were assigned to their respective genetic cluster by partial hsp60 sequencing. All study isolates belonging to genetic clusters III and VI were selected to evaluate the specificity of the enterobacterial repetitive intergenic consensus (ERIC) and repetitive extragenic palindromic (REP) polymerase chain reaction (PCR) for the identification of clonal isolates belonging to the E. cloacae complex. For these 56 isolates, PFGE was performed, yielding 3 pairs of isolates with indistinguishable patterns. ERIC PCR resulted in 7 groups with identical patterns, together encompassing 49 study isolates. Comparing the ERIC PCR with the PFGE, a specificity of 14% considering the detection of "clonal" isolates was calculated. In this respect, REP PCR performed much better, yielding a specificity of 90%. An unweighted pair-group method with arithmetic averages tree based on ERIC PCR patterns allowed an accurate classification of the isolates to the respective genovars, suggesting that the ERIC PCR differentiates between genovars rather than between strains. In contrast, REP PCR differentiates better on the strain level. A proposed diagnostic system for the detection of subsumed outbreak strains of the E. cloacae complex is presented. It is based on an initial REP PCR, which should be confirmed by PFGE in cases of identical patterns, whereas ERIC PCR does not seem to be useful for the detection of outbreak strains when dealing with isolates of the E. cloacae complex.

Gynecologic concerns in the treatment of teenagers with cloaca.

BACKGROUND/PURPOSE: Gynecologic anomalies are common in patients with persistent cloaca, but, except for hydrocolpos, these patients remain asymptomatic in the neonatal period. Anatomic abnormalities may become manifest in puberty when menses occurs. The authors sought to describe the sequelae of these anatomic defects in the teenage cloaca patient and to determine recommendations for prevention and treatment in the neonatal period. METHODS: From a series of 198 patients operated on for persistent cloaca, the authors report a group of 22 patients who have reached puberty. RESULTS: Seven patients are menstruating normally. Six patients have primary amenorrhea because of absent or atretic uteri. Nine patients presented with abdominal pain and cystic abdominal masses and required surgical resection of inflamed collections of old blood in uteri, hemiuteri, tubes, blind vaginas, hemivaginas, or in the peritoneum. The common denominator of this last group was an obstruction of one or more Mullerian structure that interfered with the drainage of menstrual blood. Asymmetric gynecologic anatomy or a vaginal atresia in the neonatal period seemed to correlate with future obstruction to menstrual flow. CONCLUSIONS: To prevent future problems, the management of the neonatal cloaca must include the early clarification of the gynecologic anatomy, specifically the patency of Mullerian structures. Unilateral atretic structures and tubes connected to atretic uteri should be resected. Also, clinicians must be suspicious of menstrual problems in teenagers operated on early in life for persistent cloaca.

Septation and differentiation of the embryonic human cloaca.

BACKGROUND/PURPOSE: Limitations in methodologies have fostered controversy regarding the septation of the human embryonic cloaca. The aim of this study was to evaluate the septation of the human embryonic cloaca. METHODS: Using the Carnegie Embryological Collection and specimens at Johns Hopkins, Baltimore, MD, the authors studied 12 embryos and five fetuses. Embryo photomicrographs were reconstructed using three-dimensional modeling. RESULTS: In Carnegie stage 13 the authors observed a cloaca, distinct primitive urogenital sinus, and anorectum separated by the urorectal septum. The primitive urogenital sinus and anorectum enter the cloaca separated from the amniotic space by the cloacal membrane. As the embryo becomes a fetus it lengthens, grows, expands and rotates through a process called transformation. Transformation gives rise to a loss of caudal curvature and a decrease in distance between the septum and membrane, but these structures do not fuse. Disintegration of the cloacal membrane produces openings for the urogenital sinus and anorectum. CONCLUSIONS: The observations suggest that the urogenital sinus and anorectum form early and are separated by the urorectal septum as a passive structure. There does not appear to be septation or differentiation of the cloaca itself.

Molecular properties and metabolic effect on blood cells produced by a new toxin of Enterobacter cloacae.

A new toxin of Enterobacter cloacae able to lyse erythrocytes and leukocytes was found. Purification of the toxin was performed by salt precipitation, gel filtration, ion exchange and HPLC in C8 column. SDS-PAGE electrophoresis showed more than one bank corresponding to the leukotoxin able to form polymers and aggregate like some pore-forming cytotoxins (RTX). In culture supernatant the toxin showed 1 HU/ml (hemolytic unit) and 1.5 LU/ml (leukotoxic unit); after purification it reached 15 HU/ml and 20 LU/ml. The ratio between HU and percentage red cells affected the lytic capacity. E. cloacae toxin stimulated the oxidative metabolism of neutrophils, but over 50 microg toxin/ml the stimulus ceased as it was shown by NBT assay due to cell death. Chemiluminescence evidenced an increase in superoxide anion generation, but an excess of toxin interfered with this stimulus, as was previously observed in HlyA Escherichia coli toxin. Cross-reaction was found by immunoblotting with this HlyA. E. cloacae toxin presented higher amounts of proline, valine, aspartic and glutamic acids than HlyA. E. cloacae toxin was similar to HlyA in the prescence of a glycine-rich DNA sequence and in the observed effect of calcium on toxin activity. E. cloacae toxin did not cross-react by immunoblotting with hemolysin HmpA of Proteus.

Biological control of an insect pest by gut-colonizing Enterobacter cloacae transformed with ice nucleation gene.

The ice nucleation (IN) gene inaA of epiphytic Erwinia (Pantoea) ananas IN10 was transformed into Enterobacter cloacae WBMH-3-CMr originated from the faeces of silkworms. The transformant designated as Ent. cloacae WBMH-3-CMr(pICE6S13) exhibited IN activity, unlike the parent strain. The transgenic strain was ingested by mulberry pyralid larvae, fed on detached mulberry leaves, and the supercooling capacity and cold hardiness of these larvae were examined. The mean supercooling point (SCP) of the larvae ingesting the transgenic strain was - 3.3 degrees C, 8 degrees C higher than that of larvae treated with distilled water (control) and 1.5 C higher than an ice nucleation active (INA) strain of Erw. ananas. The SCPs of the larvae were stably maintained over the 9 d after ingestion. The maintenance of these high SCPs was due to transgenic Ent. cloacae having a more stable and efficient gut colonization than Erw. ananas, which is identified by the distribution of a narrower range of SCPs (-2 to -5 degrees C) in larvae treated with the transgenic stain. Furthermore, most of the larvae ingesting the transgenic strain froze and died when they were exposed to cold conditions of -5 degrees C for 18 h, 3 or 7 d after ingestion. In contrast, most of the larvae ingesting no bacterium did not die under similar conditions. On the other hand, the growth ability of Ent. cloacae WBMH-3-CMr on mulberry leaves tended to be lower than that of epiphytic Erw. ananas, as assayed by pot tests. These findings would expand the possibility of biological control using INA bacteria since Ent. cloacae would harbour a broader host (insect) range for gut colonization and a smaller affinity to plants to benefit from prevention of plant frost injury.

Urinary tract infections caused by endemic multi-resistant Enterobacter cloacae in a dialysis and transplantation unit.

In the period 1994-1998, 42 multi-resistant Enterobacter cloacae isolates responsible for urinary tract infections (UTIs) were obtained from children hospitalized in our dialysis and transplantation unit. E. cloacae isolates obtained between 1994 and 1996 were susceptible to aminoglycosides, carbapenems and fluoroquinolones, whereas E. cloacae isolates obtained between 1997 and 1998 were susceptible to carbapenems and fluoroquinolones, only. All isolates were characterized by use of the polymerase chain reaction-based random amplification of polymorphic DNA and pulsed-field gel electrophoresis. It was found that the majority of multiresistant E. cloacae isolates obtained during 1997-1998, and all isolates obtained during 1994-1996, belonged to predominant clones A or B. These strains were responsible for gastrointestinal tract colonization and UTI of renal transplant recipients for several years, and persisted as endemic E. cloacae strains in the dialysis and transplantation unit from 1994 to 1998.

Molecular epidemiology of systemic infection caused by Enterobacter cloacae in a high-risk neonatal intensive care unit.

OBJECTIVE: To investigate the molecular epidemiology of systemic nosocomial infections caused by Enterobacter cloacae. SETTING: Neonatal intensive care unit (NICU) of a tertiary-care university hospital. PATIENTS: Forty-two high-risk neonates with systemic infections caused by E. cloacae. METHODS: From 1995 to 1997, the variables associated with death in these patients were evaluated. The molecular epidemiology of the strains responsible for the systemic infections, and 14 unrelated strains, was studied using plasmid analysis and pulsed-field gel electrophoresis (PFGE). RESULTS: The overall mortality rate for infection caused by E. cloacae was 34%, whereas the crude mortality rate during the study period was 8.12% (P < .001). Gestational age (preterm neonates) and birth weight (small for gestational age) were not associated with a higher risk of death. Insertion of a venous catheter by dissection of a peripheral vein was the only invasive procedure related to death (P = .016) in this study. A molecular analysis showed that three outbreaks, each occurring in a different year, were caused by strains with distinctive DNA profiles. Only one outbreak was identified by the infection control service, in the NICU. Plasmid analysis and PFGE showed similar ability to discriminate control strains from the E. cloacae strains isolated from the neonates. CONCLUSIONS: Systemic infections caused by E. cloacae in our NICU were associated with a high mortality rate and occurred as small, unrecognized outbreaks. These results may not be generalizable because the data were from a single center.

Increase in MICs of ciprofloxacin in vivo in two closely related clinical isolates of Enterobacter cloacae.

The mechanisms of fluoroquinolone resistance in two isolates of Enterobacter cloacae, Ecl#1 and Ecl#2, from the same patient and with identical pulsed-field gel electrophoresis patterns, have been analysed. MICs of ciprofloxacin were 0.25 and 1 mg/L for Ecl#1 and Ecl#2, respectively. Ecl#2 was also more resistant to chloramphenicol and organic solvents. The quinolone resistance determining regions of gyrA/B and parC/E, and the marORA and acrB genes, were sequenced. Expression of marR, acrB, soxS, robA, ramA and fis was analysed by northern blotting. The activity of a 90 bp E. cloacae mar promoter fragment was examined with the reporter plasmid pIGJ-1mar. Sequencing the gyrAB and parCE genes revealed a single amino acid substitution in GyrA (corresponding to position 83 in GyrA of Escherichia coli) in Ecl#1 and Ecl#2 (Phe83) compared with reference strain E. cloacae DSMZ 3264 (Thr83). Ecl#2 accumulated significantly less norfloxacin and displayed higher levels of expression of marR and acrB than Exl#1, indicative of greater fluoroquinolone efflux activity. Sequencing gyrB, parC/E and marORA, and northern blotting of robA, ramA and fis, did not reveal any further differences between the two strains. No homologue of soxRS was detected in E. cloacae. Expression of GFP from pIGJ1-mar in Ecl#2 was higher than in Ecl#1. In these two closely related clinical isolates of E. cloacae, a target mutation in GyrA (Ecl#1 and Ecl#2) and increased fluoroquinolone efflux by AcrAB (Ecl#2) contribute to the resistance phenotypes, corroborating findings in vitro and in vivo about the sequential development of fluoroquinolone resistance.

Lactobacillus flora in the cloaca and vagina of hens and its inhibitory activity against Salmonella enteritidis in vitro.

Lactobacilli in the cloaca and vagina of 40 normal laying hens were investigated quantitatively and qualitatively, and their ability to inhibit growth of Salmonella enteritidis (SE) was examined using a spot-the-lawn technique. All samples of cloacal contents and half the samples of vaginal mucus were positive for lactobacilli. The means +/- SD of total Lactobacillus counts in the cloaca and those in the vagina were log10 5.5 +/- 1.1 and 2.5 +/- 2.6 cfu/g, respectively. In the cloaca, Lactobacillus acidophilus was isolated from 92.5% of hens, and Lactobacillus salivarius was isolated from 85.0% of hens, whereas Lactobacillus fermentum was isolated from only one hen. In the vagina, L. acidophilus and L. salivarius were isolated from 42.5% of hens. In the inhibition assay in vitro, all strains of Lactobacillus from cloacal contents and vaginal mucus inhibited growth of SE. There was a wide range of the inhibitory activity even in the same species. No difference of the growth inhibition zone was observed between lactobacilli from cloaca and those from vagina. The present study suggested that lactobacilli in the cloaca and vagina of hens might have a protective effect against SE colonization.

Antimicrobial susceptibility of oral isolates of Enterobacter cloacae and Klebsiella pneumoniae from a southern Chinese population.

The antibiotic susceptibilities of 59 Enterobacter cloacae and 39 Klebsiella pneumoniae human oral isolates collected from a southern Chinese population in Hong Kong were investigated for their susceptibility to eight antibiotics: ampicillin, cephalothin, cefuroxime, ceftazidime, ciprofloxacin, gentamicin, tetracycline and trimethoprim/sulfamethoxazole using the E-Test method for direct quantification of minimum inhibitory concentrations. Most strains were sensitive to all antibiotics except ampicillin and cephalothin. Ampicillin resistance was exhibited by 82% of K. pneumoniae and 69% of E. cloacae isolates. Eighty-eight percent of E. cloacae isolates were resistant to cephalothin. Several strains fell within the intermediate category of sensitivity for ampicillin (E. cloacae and K. pneumoniae), cefuroxime (E. cloacae) and tetracycline (K. pneumoniae). Comparison with other Hong Kong data suggests that resistance rates to cefuroxime, ceftazidime, ciprofloxacin, gentamicin, tetracycline and trimethoprim/sulfamethoxazole exhibited by the oral isolates are generally lower than in enterobacters and Klebsiella spp. isolated from urine, skin and soft tissues in Hong Kong populations.

A rob-like gene of Enterobacter cloacae affecting porin synthesis and susceptibility to multiple antibiotics.

A chromosomal gene of Enterobacter cloacae affecting the synthesis of major outer membrane proteins in E. cloacae and Escherichia coli was cloned by using selection for resistance to cefoxitin in E. coli. The presence of the gene, when plasmid-borne, led to a decrease in the amount of porin F in E. cloacae and the amount of OmpF in E. coli and caused 2- to 32-fold increases in the MICs of chloramphenicol, tetracycline, quinolones, and beta-lactam antibiotics. The gene encoded a 33-kDa protein, similar (83% identity) to the protein Rob involved in the initiation of DNA replication in E. coli, which was called RobA(EC1) by analogy. RobA from E. cloacae was found to inhibit ompF expression at the posttranscriptional level via activation of micF, a gene also apparently present in E. cloacae, as detected by PCR. As with its homolog from E. coli, RobA(EC1) is related to the XylS-AraC class of positive transcriptional regulators, along with MarA and SoxS, which also cause a micF-mediated decrease in the level of ampF expression.

PCR analyses of tRNA intergenic spacer, 16S-23S internal transcribed spacer, and randomly amplified polymorphic DNA reveal inter- and intraspecific relationships of Enterobacter cloacae strains.

PCR analysis of tRNA intergenic spacer (tDNA-PCR) and of the 16S-23S internal transcribed spacer (ITS-PCR) and random amplified polymorphic DNA (RAPD) analysis were evaluated for their usefulness in characterization of Enterobacter cloacae strains isolated from both clinical origins and vaccine microbial contamination. tDNA-PCR presented specific and reproducible patterns for Enterobacter sakazakii ATCC 29004, Enterobacter aerogenes ATCC 13048, and Enterobacter cloacae ATCC 13047 and 23355 that presented the same profile for all 16 E. cloacae isolates, offering an alternative tool for species-level identification. ITS-PCR and RAPD analysis yielded completely different banding patterns for the 20 strains studied, except for E. cloacae strains isolated from different batches of vaccine that exhibited a unique pattern, suggesting contamination by the same strain. The combined use of tDNA-PCR and ITS-PCR in a one-step protocol allows accurate identification and typing of E. cloacae strains a few hours after the colony has been isolated.

Involvement of gacS and rpoS in enhancement of the plant growth-promoting capabilities of Enterobacter cloacae CAL2 and UW4.

The plant growth-promoting bacteria Enterobacter cloacae CAL2 and UW4 were genetically transformed with a multicopy plasmid containing an rpoS or gacS gene from Pseudomonas fluorescens. The transformed strains were compared with the nontransformed strains for growth, indoleacetic acid (IAA) production, antibiotic production, 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase activity, siderophore production, cell morphology, and the ability to promote canola root elongation. All transformed strains had a longer lag phase, were slower in reaching stationary phase, and attained a higher cell density than the nontransformed strains. Transformation resulted in cells that were significantly shorter than the nontransformed cells. The transformed strains also produced significantly more IAA than the nontransformed strains. Introduction of rpoS or gacS from Pseudomonas fluorescens was associated with a reduction in the production of both antibiotics, 2,4-diacetylphloroglucinol and mono-acetylphloroglucinol, produced by Enterobacter cloacae CAL2. With Enterobacter cloacae CAL2, plasmid-borne rpoS, but not gacS, increased the level of ACC deaminase activity, while introduction of rpoS in Enterobacter cloacae UW4 caused a decrease in ACC deaminase activity. Neither gacS nor rpoS significantly affected the level of siderophores synthesized by either bacterial strain. Overproduction of either GacA or RpoS in Enterobacter cloacae CAL2 resulted in a significant increase in the root lengths of canola seedlings when seeds were treated with the bacteria, and overproduction of RpoS caused an increase in canola shoot as well as root lengths.

Persistent cloaca and caudal spinal agenesis in calves: three cases.

Three newborn calves were affected by caudal spinal dysgenesis or agenesis (coccygeal vertebra) and persistent cloaca. The cloacas were lined by a mixture of transitional and colonic epithelium. The vertebral column of one calf was internalized into the cloaca. The association of persistent cloaca and caudal spinal anomalies is thought to be related to cell loss in the caudal cell mass, which affects caudal spinal column formation and cleavage of the cloaca by the urorectal septum. This association is well documented in humans and has been reported in Manx cats. By extrapolation, it appears likely to exist also in neonatal calves. Identification of cloacal lesions in neonatal animals should be cause for careful examination of the vertebral column because many of the associated spinal lesions are occult.

Gross appearance of turkey cloacae before and after single or multiple manual semen collections.

The gross appearance of the turkey cloaca was examined before and after single or multiple semen collections. All cloacae exhibited some degree of hemorrhage formation, the extent of which was dependent upon 1) frequency of semen collection, 2) number of cloacal strokes, and 3) individual differences in semen collectors' techniques. Cloacae of males subjected to multiple semen collections of more than four cloacal strokes per semen collection were the most severely injured. Cloacae examined three days after the last semen collection were nearly normal in appearance. It is suggested that cloacal hemorrhages resulting from semen collection can be minimized by 1) reducing the number of cloacal strokes per semen collection to one or two and 2) using the correct hand placement and pressure on the cloaca during the cloacal strokes.

Genomic and functional characterization of novel therapeutic lytic bacteriophages targeting multidrug-resistant Enterobacter cloacae.

The alarming rates at which extensively drug-resistant (XDR) and pandrug-resistant (PDR) Enterobacter cloacae in hospitals are increasing has begun to severely limit treatment options, and thus the urgency for alternative interventions, including bacteriophage therapy. The purpose of the study was to isolate and molecularly characterize phages that can infect E. cloacae, and, furthermore, to assess the antimicrobial efficacy of the four novel lytic bacteriophages (MMRP1, MMRP2, MMRP3, and MMRP4) against antimicrobial-resistant E. cloacae isolates and to evaluate their potential as alternative therapeutic strategies. These novel phages were characterized by plaque morphology, transmission electron microscopy (TEM), host range testing, thermal and chloroform stability assays, bacterial reduction assays, and whole-genome sequencing (WGS). Among 27 clinical isolates, MDR, XDR, and PDR phenotypes were observed in 20 (74.1%), six (22.2%), and one (3.7%) isolates, respectively. All four phages produced clear lytic plaques (0.5-3.0 mm) with titers reaching up to 6 × 1010 PFU/mL, and the phage cocktail lysed 81.4% (22 of 27 isolates) of clinical isolates with high host specificity. TEM revealed that all four E. cloacae-infecting phages (MMRP1, MMRP2, MMRP3, and MMRP4) belong to the class Caudoviricetes, exhibiting icosahedral capsids, tailed morphology, and double-stranded DNA genomes, consistent with current ICTV classification criteria. Whole genome sequencing and comparative phylogenetic analysis further resolved the taxonomic placement of these phages at the family level, positioning MMRP1 within the family Demerecviridae and MMRP4 within the family Straboviridae. All phages were stable from -20 to 40 °C and were unaffected by exposure to chloroform. Phage cocktail reduced bacterial OD₆₀₀ to ≤ 0.3 within 4 h in the bacterial reduction test. WGS revealed large circular dsDNA genomes of ~132 kbp (MMRP1) and ~149 kbp (MMRP4), GC content of 38%, and modular architectures encoding structural, lytic, and replication gene modules. The most striking and highlighted suggestion that in vitro evaluation of MMRP1 and MMRP4 are highly recommended to more deeper future experimental studies to combat MDR E. cloacae nosocomial infections supported by genomic foundation and eventually, the possibility to be suitable for phage-engineering applications in clinical settings.
