Background and Objectives: Salmonella infections are endemic in many developing countries with poor sanitary conditions, but emerge sporadically as a serious public health threat in developed countries. Infections with multidrug resistant (MDR) strains of Salmonella have been associated with treatment failures. Salmonella spp. resistant to extended spectrum cephalosporins are increasing in prev...

INTRODUCTION The prevalence and antimicrobial susceptibility patterns of the bacterial enteropathogens Vibrio cholerae, Salmonella species and Shigella species were investigated. METHODOLOGY A total of 877 stool samples were received for culture at the National Public Health Laboratory (NPHL), Kathmandu, Nepal, during January 2002 to December 2004, from diarrhoea patients attending Shukraraj ...

Background and aims: Salmonella spp. infect cold-blooded and warm-blooded animals and maycause a worldwide zoonotic disease, salmonellosis, in infected animals. Rodents can be Salmonellacarriers without any signs of salmonellosis. The frequency of salmonella contamination, the presence ofvirulence genes (SpvR and SpvB) and antibiotic resistance pattern of isolated Salmonella w...

In this study, the serogroup and susceptibility patterns of Shigella and Salmonella spp. isolated from stool cultures were determined using standard laboratory procedures. Among the 76 Shigella isolates serogroup B (Sh. flexeneri) was the most prevalent species (54.0%) and among the 37 Salmonella strains serogroup B was also the most prevalent (81.1%). Antibiograms of Shigella and Salmonella sp...

OBJECTIVES Gastrointestinal tract infection is still one of the serious public health problems in many geographic areas and is endemic in most countries including Iran. Early detection of the gastrointestinal tract pathogens can be extremely important. The aim of the current study was to apply a shortened time-multiplex polymerase chain reaction (PCR) for rapid and simultaneous detection of Sal...

Salmonella spp. are remarkably adaptable pathogens, and this adaptability allows these bacteria to thrive in a variety of environments and hosts. The mechanisms with which these pathogens establish within a niche amid the native microbiota remain poorly understood. Here, we aimed to uncover the mechanisms that enable Salmonella enterica serovar Typhimurium strain ATCC 14028 to benefit from the ...

Objective—To determine whether an anti-Salmonella bacterium is involved in control of pathogen load in persistently infected cattle herds. Animals-24 Holstein calves experimentally infected and 39 Holstein cows naturally Infected with Salmonella spp. Procedures—An Escherichia coil (designated as F8E5) that possessed anti-Salmonella activity was isolated from Salmonella-negative bovine feces obt...

  Abstract   Background: Diarrhea has been recognised as a major public health problem worldwide. Aprospective study was performed to determine the etiology, seasonal and age prevalence, relevant laboratory investigations, sensitivity of isolated microorganisms to current medication, and practical approaches to the diagnosis and management of diarrhea in Iran, as a developing country.   Methods...

OBJECTIVE To describe the prevalence and antimicrobial resistance of Salmonella spp. in frozen chicken carcasses at retail from 15 Brazilian cities. METHODS A descriptive study of data from the Brazilian National Program for Monitoring the Prevalence of Bacterial Resistance in Chicken (PREBAF) was conducted from September 2004 to July 2006. The program collected chicken carcasses in 15 state ...

We analyzed the prevalence of thermotolerant Campylobacter spp. compared that of to Salmonella spp. in raw yolk and on eggshells. A total of 2,710 eggs were investigated for each bacterium. Viable bacteria were found in 4.1% (Campylobacter spp.) and 1.1% (Salmonella spp.) of the eggshell samples, whereas the egg yolk samples were negative for both bacteria.
