The study was undertaken to evaluate the prevalence of enteric fever, antimicrobial susceptibility pattern, regional and seasonal distribution of Salmonella spp. in Nepal. Salmonella spp., the causative organism for enteric fever, is a major public health problem; especially in the developing countries and has gradually developed resistance to many antibiotics. Surveillance of antimicrobial res...

BACKGROUND AND OBJECTIVES Salmonella is an important food-borne pathogen in humans. Strains of Salmonella spp. that producing extended-spectrum β-Lactamases have become a concern in medicine regarding both antimicrobial treatment and infection control program. The objective of this study was to describe the antibiotic susceptibility, ESBL production and determining the prevalence of the bla CTX...

Food pathogens are the cause of foodborne epidemics, therefore there is a need to detect the pathogens in food productions rapidly. A pre-enrichment culture followed by selective agar plating are standard detection methods. Molecular methods such as qPCR have provided a first rapid protocol for detection of pathogens within 24 h of enrichment culture. Biosensors also may provide a rapid tool to...

BACKGROUND Salmonella species (spp.) are zoonotic enteric bacteria able to infect humans, livestock and wildlife.However, little is known about the prevalence and the presence of the different serovars in wildlife. Considering the wide distribution of wild boars and the feeding behaviour (omnivorous scavengers), wild boars may be a good indicator for environmental presence of Salmonella spp. Th...

salmonella spp. are zoonotic enteric bacteria able to infect humans, livestock and wildlife. the aim of this study was to investigate the prevalence of salmonella (spp.) and to determine antibiotic susceptibility, serogrouping and presence of inva gene (salmonella invasion gene a) in the detected strains in wild captive herbivores in iran. the fecal samples of 103 animals from 8 different sp...

The objectives of this study were (1) to evaluate the frequency with which feed ingredients or mixed feeds in cattle feedlots were contaminated with Escherichia coli and Salmonella spp. and (2) to evaluate the antimicrobial susceptibility patterns of non-type-specific Escherichia coli and Salmonella spp. recovered from feed ingredients or mixed feeds. Approximately 30 individual samples were co...

Ultraviolet energy at a wavelength of 253.7 nm (UVC) was investigated for its bactericidal effects on the surface of Red Delicious apples, leaf lettuce and tomatoes inoculated with cultures of Salmonella spp. or Escherichia coli O157:H7. Inoculated samples were subjected to different doses ranging from 1.5 to 24 mW/cm(2) of UVC and enumerated on tryptic soy agar plus 0.05 g/l nalidixic acid to ...

AIM The present study was undertaken to determine bacterial load as well as characterize bacterial flora of ready to eat (RTE) betel leaf sold at local markets in Mymensingh city. MATERIALS AND METHODS A total of 25 RTE betel leaf samples were collected from five local markets such as Kamal-Ranjit (KR) market, Shesh more, Kewatkhali, Jobber more, and Ganginar par. RESULTS Total viable count...

Polymerase chain reaction (PCR) assay and conventional microbiological methods were used to detect bacterial contamination of egg shells and egg content in different commercial housing systems, open house system and evaporative cooling system. A PCR assay was developed for direct detection using a set of primers specific for the invasion by A gene (invA) of Salmonella spp. PCR detected the pres...
