1. Isolation and molecular characterization of Campylobacter jejuni from chicken and human stool samples in Egypt
Abstract Two hundred broiler chicken samples, 160 laying chicken samples and 75 human stool samples were collected in Egypt. The samples were microbiologically examined, and the C. jejuni isolates were confirmed biochemically and by PCR targeting the mapA gene of C. jejuni. The prevalence of the cadF virulence gene was then determined using PCR. A total of 1

2. Contribution of flagella and motility to gut colonisation and pathogenicity of Salmonella Enteritidis in the chicken
ABSTRACT Salmonella Enteritidis causes fowl paratyphoid in poultry and is frequently associated to outbreaks of food-borne diseases in humans. The role of flagella and flagella-mediated motility into host-pathogen interplay is not fully understood and requires further investigation. In this study, one-day-old chickens were challenged orally with a wild-type

3. Prevalence, serotyping and antimicrobials resistance mechanism of Salmonella enterica isolated from clinical and environmental samples in Saudi Arabia
Abstract Salmonella is recognized as a common foodborne pathogen, causing major health problems in Saudi Arabia. Herein, we report epidemiology, antimicrobial susceptibility and the genetic basis of resistance among S. enterica strains isolated in Saudi Arabia. Isolation of Salmonella spp. from clinical and environmental samples resulted in isolation of 33 s

4. Different methods to quantify Listeria monocytogenesbiofilms cells showed different profile in their viability
Listeria monocytogenes is a foodborne pathogen able to adhere and to form biofilms in several materials commonly present in food processing plants. The aim of this study was to evaluate the resistance of Listeria monocytogenes attached to abiotic surface, after treatment with sanitizers, by culture method, microscopy and Quantitative Real Time Polymerase Cha

5. Gene detection and toxin production evaluation of hemolysin BL of Bacillus cereus isolated from milk and dairy products marketed in Brazil
Bacillus cereusis an ubiquitous, spore-forming bacteria that can survive pasteurization and the majority of the heating processes used in the dairy industry. Besides, it is a pathogen responsible for different types of food poisoning. One type of foodborne disease caused by B.cereusis the diarrheal syndrome, which is caused by the ingestion of vegetative cel

6. Evaluation of a multiplex selective enrichment broth SEL for simultaneous detection of injured Salmonella, Escherichia coli O157:H7 and Listeria monocytogenes
Although many rapid and high throughput molecular methods have been developed in the recent years for the multiplex detection of foodborne pathogens, the simultaneous recovery and enrichment of sublethally injured cells is still a problem that needs to be considered. Combined with previous established multiplex real-time PCR assay, the capability of simultan

7. Salmonella spp na cadeia de produção de carne bovina de exportação: ocorrência, perfil de susceptibilidade antimicrobiana, genes de virulência e perfil de macrorrestrição do PFGE / Salmonella spp in export beef production chain: occurrence, antimicrobial susceptibility, virulence genes and PFGE macrorestriction profile
Beef is exposed to contamination at all stages of the production chain, particularly in operations where it is more manipulated and when Good Hygiene Practices are not properly followed. The most relevant pathogen in bovine meat is Salmonella spp, the major causative agent of foodborne diseases in the world. Several studies have shown that Salmonella spp can

8. Detection of enterotoxin genes of Staphylococcus sp isolated from nasal cavities and hands of food handlers
Food handlers, an important factor in food quality, may contain bacteria that are able to cause foodborne disease. The present study aimed to research coagulase-negative (CNS) and -positive staphylococci (CPS) in 82 food handlers, analyzing nasal and hand swabs, with identification of 62 CNS (75.6%) and 20 CPS strains (24.4%). Staphylococcal enterotoxins gen

9. Cinética de crescimento de Salmonella enteritidis envolvida em surtos alimentares no RS : uma comparação com linhagens de outros sorovares / Growth kinetics of Salmonella Enteritidis involved in outbreaks of foodborne illness in Rio Grande do Sul, southern Brazil: a comparison with other serovar strains
No período de 1999 a 2002, uma linhagem geneticamente caracterizada de Salmonella Enteritidis esteve envolvida em mais de 90% das salmoneloses ocorridas no RS. Este trabalho teve por objetivo avaliar a cinética de crescimento dessa linhagem, comparando-a com o crescimento de uma linhagem de S. Typhimurium e de S. Bredeney não envolvida em surtos alimentar

10. Listeria monocytogenes em linguiças do tipo frescal vendidas a varejo no município de Salvador-BA e eficácia do bacteriófago P100 no controle da contaminação pelo patógeno.
The outbreaks of Food-borne Diseases are a reason of concern for the food industries and public health organs. Listeria monocytogenes is known as an important pathogen causing diseases transmitted by food and its importance has been growing since the 1980s. Although the number of disease cases per year is relatively low, the infection can be serious, with le

11. Estado viável não cultivável em Salmonella enterica: indução, perfil de proteínas intracelulares e detecção de mRNA / Viable but nonculturable state in Salmonella enterica: induction, intracellular protein profile, and mRNA detection
The foodborne pathogen Salmonella spp. enters into a viable but nonculturable state (VBNC) in response to adverse environmental conditions. The presence of VBNC cells is a public health concern since it may be overlooked under standard routine laboratory procedure, resulting in improper assessment of contaminating pathogens in food. This work was done to inv

12. Salmonella spp : avaliação epidemiológica de surtos notificados no Paraná e caracterização de isolados epidêmicos e de origem avícola
Salmonella enterica subsp. enterica serovar Enteritidis (SE) is the main pathogen responsible for foodborne outbreaks in Paraná. Epidemiological surveillance of SE requires effective methods for subtyping and investigation of genetic diversity and origin of isolated ones, considering that this serovar presents high degree of genetic homogeneity. The use of
