We made an open label, multicenter, non-comparative study to assess the efficacy and safety of oral gatifloxacin, 400 mg PO given once-daily during 7 to 14 days for the treatment of adult outpatients with community-acquired pneumonia at five Brazilian medical facilities. Among the 86 subjects available for clinical evaluation, 84 (98%) were cured. The bacteriological eradication and presumed eradication rate was 98% (52/53) among the 44 (51%) patients who were bacteriologically evaluated. Drug-related adverse events were reported by 27% of the patients, diarrhea being the most frequent, occurring in 12% of patients. Adverse events were considered mild (89%) or moderate (11%). We conclude that a 7-14 day course of gatifloxacin, 400 mg PO given once daily is safe and effective for the treatment of community-acquired pneumonia. The drug had a favorable safety profile and a good clinical and bacteriological efficacy.
In this study, we examined the growth differences of males and females following a sex reversion, and the growth hormone (GH) expression variation between sexes of European eels [Anguilla anguilla (L.)]. A high percentage of females (88%) was found in the group fed with estradiol 17beta compared to the control group (comprised of only 6% female eels), which was defined as the male population. Significant differences between growth rate and size were found following 480 days of growth, whereby the males reached 60+/-4.3 g (means+/-SE) in size and the females 73.4+/-5.9 (g+/-SE); after 600 days, the males reached 114.1+/-4.3 and the females 171+/-11.7 (g+/-SE). A cDNA coding for the complete growth hormone of the European eel A. anguilla (eeGH) was cloned by RACE PCR using several sets of degenerate oligonucleotides. The eeGH cDNA coding region is 627 bp long. A sequence comparison of eeGH with Anguilla japonica GH (jeGH) cDNA showed a 98% identical base. Comparison of the deduced amino acid sequence revealed 99% identical residues, meaning that a difference exists in only two of the 209 residues. In both cases, the differing residues in the eeGH amino acid sequence are lysine. We measured the mRNA levels of growth hormone in the pituitaries of male and female eels growing at different rates. A significantly higher expression of eeGH was found in the female eels in comparison to the males. These results show that different levels of GH transcription eeGH can explain the growth rate differences between male and female European eels.
Fermented liquid feed (FLF) protects broiler chickens against colonisation with Salmonella. While Campylobacter causes more disease cases in humans than Salmonella, the effect of FLF on Campylobacter was assessed. The fermented liquid feed is a moistened feed with a high number of lactobacilli, a high concentration of lactic acid, and a pH of 4. In three experiments Campylobacter was orally applied to individually housed 9-day-old broiler chickens. A significant reduction of susceptibility, as determined by cloacal swabs, was observed. At any moment where an animal has not started to shed Campylobacter yet, the probability to start shedding Campylobacter in a subsequent small time interval was nine times as high for the control chickens than for the animals that were fed FLF. FLF did not consistently change the Campylobacter colonisation level in the caeca. It was concluded that FLF could reduce the probability of introduction of Campylobacter in broiler flocks. In an experiment where some chickens were simultaneously inoculated with Salmonella enteritidis and Campylobacter, no interaction on susceptibility or caecal colonisation level was observed.
