Active efflux pump is a primary fluoroquinolone resistant mechanism of clinical isolates of Salmonella enterica serovar Typhimurium. RamA is an essential element in producing multidrug resistant (MDR) S. enterica serovar Typhimurium. The aim of the present study was to elucidate the roles of RamA on the development of ciprofloxacin, the first choice for the(More)
Epidemiological studies of macrolide resistance in Campylobacter jejuni demonstrated that infections with macrolide-resistant C. jejuni could be associated with an increased risk of adverse events, development of invasive illness or death compared to macrolide-susceptible isolates. In this study, an in vitro induction experiment was conducted using(More)
Physiologic and phenotypic alterations in the context of antibiotic resistance have been extensively studied in some bacteria. However there are not enough data addressing these alterations due to macrolide resistance in Campylobacter jejuni. The present study examined the fitness cost imposed by different macrolide resistance mutations and the phenotypic(More)
A total of 260 E. coli isolates out of 342 bacterial isolates were obtained from faecal samples collected from 300 diarrhoeic calves from different localities in Khartoum State. The isolates were confirmed using API 20E and VITEK2 identification systems. Ninety isolates were confirmed by API 20E strips and twenty isolates scored high probability percentages(More)
