To the Editor: Extended-spectrum β-lactamase (ESBL)– producing members of the family Enterobacteriaceae (enterobacteria) are a worldwide problem (1), but little data are available from central Africa (2). In recent years, ESBL-producing Enterobacteriaceae isolates have shifted from the hospital to the community and the environment (1). The aim of this study was to assess the presence of ESBL-pr...

Phase variation of Coxiella burnetii is due to variation of the lipopolysaccharide (LPS), a phenomenon analogous to smooth-to-rough LPS variation of gram-negative enteric bacteria. Virulent enterobacteria usually have a smooth LPS and resist serum killing, whereas avirulent rough LPS mutants are sensitive to complement-mediated serum killing. Like gram-negative enterobacteria, smooth LPS phase ...

OBJECTIVES To detect the occurrence of low susceptibility to colistin (polymyxin E), a last-resort antimicrobial, among enterobacteria isolated from samples of animal origin (poultry and swine) and to find out the molecular basis of colistin resistance. METHODS Salmonella enterica and Escherichia coli were isolated from eggs and swine samples. Bacterial strains were screened for colistin resi...

In this research, the chemical and microbiological characteristics of white brined cheeses produced with five differen starter cultures, namely: traditional kefir grain, commercial kefir, commercial yogurt, traditional yogurt and commercial cheese starter culture, were examined during 60- day ripening period. Results of statistical analysis showed that the type of starter culture had a signific...

BACKGROUND T cell responses to normal intestinal bacteria or their products may be important in the immunopathogenesis of chronic enterocolitis. AIMS To investigate the T cell specificity and cross reactivity towards intestinal bacteria. PATIENTS/METHODS T cell clones were isolated with phytohaemagglutinin from peripheral blood and biopsy specimens of inflamed and non-inflamed colon from fi...

Antibiotic-resistant enterobacteria, the vast majority of which carried transmissible R factors, were isolated from 81 out of a total of 100 healthy infants. There was surprisingly little correlation between previous antibacterial therapy and the resistant enterobacterial flora.

In Ouagadougou, grilled meats in the form of pieces and brochettes are very popular well-known to consumers. The aim this study was assess microbial quality mutton meat sold Burkina Faso. A total 120 samples were collected from 20 grillers 60 fresh meat. sampling done between month August 2018 February 2019. analyzed according standard methods. test performed counts Aerobic Mesophilic Bacteria ...

During 2010, we evaluated the presence of extended-spectrum β-lactamase- and AmpC-producing enterobacteria in broiler chickens at slaughter. Samples (70 carcasses and 51 ceca) from 4 flocks were analyzed by direct plating and after enrichment. Extended-spectrum β-lactamase producers were found in 88.6% and 72.5% of carcasses and ceca, respectively; AmpC producers were found in 52.9% and 56.9% o...
