Prevalence of enteric parasites in homosexual patients attending an outpatient clinic.

A total of 372 pooled stool specimens from 274 homosexual men with diarrhea were submitted for parasitologic examination over a 2.5-year period. Each two-vial pooled specimen set contained portions of stool from 3 consecutive days in Formalin and polyvinyl alcohol. Of the 274 patients, 133 (48.5%) harbored one or more intestinal protozoa, with 161 (43.3%) of the 372 specimens submitted being positive for one or more organisms. The parasites identified included Entamoeba histolytica (71 patients), Giardia lamblia (22 patients), Endolimax nana (106 patients), Entamoeba coli (39 patients), Entamoeba hartmanni (25 patients), Dientamoeba fragilis (3 patients), Iodamoeba bütschlii (2 patients), and Chilomastix mesnili (2 patients). Cryptosporidium sp. (2 patients) and Isospora belli (1 patient) were also detected. Results of this study support the experience of other workers regarding high rates of infection with intestinal parasites in the homosexual population and also indicate that symptomatic individuals belonging to this acquired immunodeficiency syndrome risk group be screened for both common and uncommon intestinal pathogens.

Suppurative lymphadenitis with Yersinia enterocolitica.

Extraintestinal suppurative complications of Yersinia enterocolitica infections are rarely observed. Two cases of suppurative lymphadenitis due to Yersinia enterocolitica are reported which mimicked other, more common disorders.

Nosocomial multiply resistant Providencia stuartii: a long-term outbreak with multiple biotypes and serotypes at one hospital.

A long-term outbreak of urinary tract-associated multiply resistant Providencia stuartii occurred in a large medical facility that included a 513-bed chronic care unit. The unique characteristics of this outbreak were that from within a single medical facility, P. stuartii with multiple serotypes, biotypes, and antibiograms could be identified. The organisms isolated had five different biotypes, seven different antibiograms, and two major serotypes. All of the organisms were susceptible to amikacin, cefamandole, and cefoxitin. Application of standard infection control measures impeded the spread of this outbreak, and it slowly terminated 16 months later.

Identification of Pseudomonas aeruginosa with the API-20E system.

The API-20E multitest system was found to be capable of identifying Pseudomonas aeruginosa isolates at least to the level of the Pseudomonas fluorescens group within 18 h at 35 degrees C. Additional tests, such as the acetamide reaction, growth at 42 degrees C, and the oxidative (OF) glucose test, assisted in the speciation of P. aeruginosa.

Bacteriological Techniques↗

Small-colony forms of enteric bacteria after exposure to aminoglycosides.

Small colony forms of enteric bacteria were isolated in vitro after exposure of near-lethal amounts of aminoglycosides. These small-colony forms were several times more resistant to all aminoglycosides than the parent clones. A small form of Escherichia coli was isolated directly from a clinical specimen, along with a more sensitive larger colony.

The urometer as a reservoir of infectious organisms.

With the aid of epidemiologic tools such as serotyping and bacteriocin typing, organisms involved in hospital-acquired infections were traced to their hospital reservoir. One of these reservoirs was an instrument used to measure specific gravity of urine, the urometer.

Cutaneous abscesses. Anaerobic and aerobic bacteriology and outpatient management.

Specimens from 135 cutaneous abscesses in outpatients were cultured anaerobically and aerobically. Of these, 4% were sterile and 29% yielded pure cultures, predominantly of Staphylococcus aureus. Aerobic species were isolated from all anatomic areas. Anaerobes were found with a frequency comparable to aerobes in all nonperineal areas except the hand. In contrast, abscesses in the perineal region contained a greater variety and frequency of anaerobes. Only two patients were febrile. All abscesses were treated with incision and drainage, and all healed without complication, including those 74% that were treated without adjunctive antibiotics. Primary management of cutaneous abscesses should be incision and drainage. In general, routine culture and antibiotic therapy are not indicated for localized abscesses in patients with presumably normal host defenses.

Rapid detection and identification of enteric bacteria from blood cultures.

The BACTEC radiometric system and Inolex Enteric I card were used in conjunction for the rapid detection and presumptive identification of enteric gram-negative rods in blood cultures. Excellent correlation was obtained between the Inolex card and routine identification techniques when organisms from both artificially inoculated and clinical blood cultures were studied. In many instances, the culture report was available less than 24 hr after receipt of the specimen.

Sodium polyanethol sulfonate sensitivity of anaerobic cocci.

Growth of Peptostreptococcus anaerobius was shown to be totally inhibited by sodium polyanethol sulfonate (SPS). Other anaerobic cocci grew in the presence of SPS although some strains of Peptococcus prevotii and Peptococcus magnus showed delayed growth. A SPS disk assay for the presumptive identification of P. anaerobius is described.

Parasitic screening of a refugee population in Illinois.

In a one year period in Illinois, 4,695 stool specimens from refugees for parasitologic screening and 733 diarrheal specimens from non-refugees were tested by routine ova and parasite examination- concentration and permanent stained smear. Patients infected with pathogens were as follows: African group (48.9%), Middle Eastern group (56.5%), Southeast Asian group (48.9%), Eastern European group (46.6%), Hispanic group (38.0%) and non-refugee group (20.7%). The study showed differences between the various groups of refugees and the non-refugee group. The need for routine screening of this population was clearly shown.
