Porphyromonas gingivalis can induce its uptake by host epithelial cells; however, the nature and role of the P. gingivalis molecules involved in this invasion process have yet to be determined. In this study, modulation of secreted P. gingivalis proteins following association with gingival epithelial cells was investigated. Western immunoblot analysis showed that contact with epithelial cells o...

Objective: Cholecystectomy is the surgical removal of gallbladder. The gallbladder often colonized by Salmonella during typhoid fever. association between cytokine and virulence genes not well known. current study aims to identify proinflammatory cytokines, TNF-α IFN-γ, two genes, InvA PagC, extracted from S. typhi isolates obtained patients undergoing cholecystectomy.
 Materials Methods: ...

This study compared the antimicrobial susceptibility and prevalence of virulence genes in Salmonella enterica Typhimurium isolated from healthy and diseased pigs in Korea. A total of 456 Salmonella Typhimurium isolated from healthy (n = 238) and diseased (n = 218) pigs between 1998 and 2011 were investigated. In total, 93.4% of the Salmonella Typhimurium isolates were resistant to at least one ...

mannea is the most important state, which was established before median kingdom and ruled on vast part of northwestern iran for several centuries. manneaen were from hurrian race and language and probably entered the region about 1500 b.c. in their political life although they suffered many inva-sions from assyria and urartu, they kept their political and cultural independence and expended thei...

Background: Foods of animal origin are major vehicles Salmonella infections and a serious public health problem with increasing concern in the world, particularly for developing countries. More recently review studies on prevalence spp. dairy products demonstrate, it has been median 6% raw milk products. However, almost all prior works this area limited to biochemical confirmation suspected iso...

AIM This study was carried out to determine the prevalence, distribution, and identification of Salmonella serotypes in diarrheagenic infants and young animals, including sewage waste and fresh vegetables. MATERIALS AND METHODS A total of 550 samples were processed for the isolation of Salmonella spp., using standard microbiological and biochemical tests. Further polymerase chain reaction (PC...

Salmonella infections have been implicated in large-scale die-offs of wild birds in the United States. Although we know quite a bit about the epidemiology of Salmonella infection among domestic fowl, we know little about the incidence, epidemiology, and genetic relatedness of salmonellae in nondomestic birds. To gain further insight into salmonellae in these hosts, 22 Salmonella isolates from d...

We have found that early in infection of the intracellular pathogen Listeria monocytogenes in Madin-Darby canine kidney epithelial cells expressing actin conjugated to green fluorescent protein, F-actin rapidly assembles (approximately 25 s) and disassembles (approximately 30 s) around the bacteria, a phenomenon we call flashing. L. monocytogenes strains unable to perform actin-based motility o...

The accurate and economical diagnosis of pathogenic bacteria is necessary for the microbiological control of laboratory animals. In this study, we developed a triplex PCR method for the direct detection of three common gastroenteric bacteria, Pseudomonas aeruginosa, Helicobacter hepaticus, and Salmonella typhimurium. Targets were specifically amplified by conventional PCR assay using a genomic ...

BACKGROUND Antimicrobial resistant Salmonella strains are a direct threat to human health when this resistance interferes with treatment and an indirect threat when resistance can be transferred to other human pathogens. The objective of the present study was to characterize antimicrobial resistant non-typhoidal Salmonella (NTS) isolates recovered from poultry industries, including a descriptio...
