Background & Objective: Molecular typing is an important tool in surveillance and outbreak investigations of human Salmonella infections. In this study, Subtyping of Salmonella Paratyphi B and C isolates derived from Iranian patients was carried out by RAPD-PCR to assess the extent of genetic diversity of these isolates. Materials & Methods: Fourteen Salmonella isolates including 6 strains of S...
Background: Salmonella can cause serious human gastroenteritis and is frequently isolated from various food samples. The cell culturing, immunoassay, and polymerase chain reactions (PCR) are the current methods to detect such pathogenic agents. However, these methods are time-consuming and labor-intensive, and thus unavailable for rapid-monitoring of Salmonella</em...
stroke scales can be classified as clinicometric scales and functional impairment, handicap scales. all studies describing stroke scales were reviewed by internet searching engines with the final search performed on january 1, 2013. the following string of keywords was entered into search engines; stroke, scale, score and disability. despite advantages of modified national institute of health s...
Background and Objectives: Salmonella spp. are one of the most important zoonotic agents with a worldwide distribution. Asymptomatic cats which may excrete Salmonella. spp for weeks can play important role in environmental contamination. The aim of this study was to access the role of rural cats in dissemination of Salmonella. spp. Methods: Salmonella excretion was evaluated in 170 samples (...
Background and Aim: Salmonella is one of the common bacterial pathogens between man and birds throughout the world. Inconsistent Salmonella contamination following consumption of eggs, as one of the main contributors of the disease has also become an important public health issue. The aim of this study was to investigate prevalence of Salmonella contamination in locally-produced eggs in Birjand...
the present study was designed to investigate the prevalence of salmonella species, their molecular characterization and antibiotic resistance in backyard chickens. a total of 1125 samples were collected from backyard chickens in two consequent samplings. in the first part, samples were included of 820 poor recently hatched chicks, hatching residuals, egg shells in the nest floor, cloacal swabs...
salmonella enterica serotypes are one of the most important food borne pathogens and significant public health concerns around the world in humans and other animal species. a total of eighty three epidemiologically unrelated clinical isolates of salmonella enterica serovars were subjected to antimicrobial susceptibility testing. eleven isolates (13.1%) which were resistant to at least 4 groups ...
Background: Multidrug resistance in Salmonella enteritidis isolates is a public health problem worldwide; the present study, therefore, was designed for antimicrobial-resistance determination in this strain. Methods: Salmonella strains isolated from poultry samples by biochemical positive and negative tests were subjected to PCR and identified as Salmonella enteritidis. For detection and ide...
Salmonella species show different disease syndromes and host specificity, according to their antigenic profile. Salmonella enterica serovar typhimurium is one of the most frequently isolated serovar from foodborne outbreaks. Poultry meat has been identified as one of the principal foodborne sources of Salmonella. In this study, the effect of microwave treatment of chicken meat samples...
