Dairy cows may serve as asymptomatic carriers of Salmonella. The potential for herd carrier status increases with herd size, and Salmonella shedding may be triggered by stresses placed on the animals. The scope of the current study is to determine the effects lactation may have on Salmonella genotypic diversity among detected serotypes. Fecal samples were collected on two sampling dates from 60...

background: poultry and poultry products are among the major sources of salmonella infections for humans. increasing occurrence of antimicrobial resistance among salmonellae has become a serious public health concern. the detection of extended spectrum b-lactamase (esbl) producers among salmonella spp. has increased in recent years. objectives: the purpose of this study was to investigate the a...

salmonellosis is one of the most important zoonotic diseases worldwide. salmonella infections in wild birds are reported frequently. the objectives of this study were to isolate salmonella serovars from a large collection of samples obtained from pet birds in tehran, iran, and then to determine the serotypes and antimicrobial susceptibility profile of the isolates. between october 2007 and augu...

Autophagy is a process whereby a double-membrane structure (autophagosome) engulfs unnecessary cytosolic proteins, organelles, and invading pathogens and delivers them to the lysosome for degradation. We examined the fate of cytosolic Salmonella targeted by autophagy and found that autophagy-targeted Salmonella present in the cytosol of HeLa cells correlates with intracellular bacterial replica...

BACKGROUND In low resource settings, Salmonella serovars frequently cause bloodstream infections. This study investigated the diagnostic performance of immunochromatographic rapid diagnostic tests (RDTs), which detect Salmonella antigens, when applied to stored grown blood culture broth. MATERIAL/METHODS The SD Bioline One Step Salmonella Typhi Ag Rapid Detection Kit (Standard Diagnostics, Re...

a hundred and five strains of salmonella havana were studied from the patients of pediatric hospital of tehran and tabriz during 1976-86. the sources of the strains in order to their frequency were from-stool, blood, spinal, fluid, wound and urine. from the epidemiological point of view salmonella havana is serotype of most non-typhoid salmonella. all of the strains had drug resistancy and most...

We have tested 750 Salmonella strains and 130 strains of other species of the family Enterbacteriaceae with the 4-methylumbelliferyl caprilate reagent (MUCAP) test. The MUCAP test is a fluorescence test for rapid identification of Salmonella strains. The non-Salmonella strains were strains sent for identification as suspected Salmonella strains and thus have phenotypes similar to those of Salmo...

Background Salmonella enterica serovar Typhimurium is one of the most important serovars of Salmonella enterica and is associated with human salmonellosis worldwide. Many epidemiological studies have focused on the characteristics of Salmonella Typhimurium in many countries as well as in Asia. This study was conducted to investigate the genetic characteristics of Salmonella Typhimurium using mu...

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...
