Campylobacter jejuni is a Gram negative, curved, motile, thermophilic and microaerophilic bacillus in Campylobacteriaceae family, which is one of the main causes of enteritis in human named campylobacteriosis. The main reservoir of Campylobacter jejuni is the alimentary tract of animals, especially chicken and turkey. Consumption of semi-cooked chicken meat, raw milk and unchlorinated water are...

A foodborne outbreak with 49 cases (22 culture positive for Campylobacter sp.) following a wedding party in the East of England was investigated. A retrospective cohort study identified an association between consumption of chicken liver pâté and infection with Campylobacter jejuni/coli. There was a statistically significant association between dose (amount of chicken liver pâté eaten) and the ...

High hemagglutinin titres against chicken erythrocytes were detected in the sera of Trypanosoma congolense-infected sheep. Adsorption of sheep sera with solubilized T. congolense resulted in marked reduction of hemagglutinin titre. Heat inactivation of the sera at 56 degrees C for 30 min had no demonstrable effects on the hemagglutinin titre. Sera collected from the sheep before trypanosome inf...

Marek's disease virus (MDV) is an alphaherpesvirus that induces T-cell lymphomas in chickens. Natural infections in vivo are caused by the inhalation of infected poultry house dust and it is presumed that MDV infection is initiated in the macrophages from where the infection is passed to B cells and activated T cells. Virus can be detected in B and T cells and macrophages in vivo, and both B an...

West Nile virus (WNV) is a pathogen to cause West Nile encephalitis when the infection occurs in the brain. Previous studies in mice identified the 2'-5' oligoadenylate synthetase 1b (Oas1b) gene as a determining factor for resistance to WNV infection. In addition, it has been suggested that human OAS1 and OASL are associated with the resistance to the WNV infection. WNV is maintained in nature...

There is paucity of data on the incidence, severity and management of chicken pox in patients receiving active chemotherapy for cancer. From October 2010 to October 2011, patients were included in this study if they developed a chicken pox infection during their chemotherapy. The details of patients' cancer diagnosis and treatment along with clinical and epidemiological data of the chicken pox ...

Newcastle disease virus (NDV) is an important avian pathogen. We previously reported that NDV triggers autophagy in U251 glioma cells, resulting in enhanced virus replication. In this study, we investigated whether NDV triggers autophagy in chicken cells and tissues to enhance virus replication. We demonstrated that NDV infection induced steady-state autophagy in chicken-derived DF-1 cells and ...

Highly pathogenic (HP) avian influenza viruses (AIV) present an ongoing threat to the world poultry industry. In order to develop new AIV control strategies it is necessary to understand the underlying mechanism of viral infection at mucosal respiratory sites. Chicken and duck tracheal epithelial cells systems (TEC) were developed to study early host responses to AIV infection on TEC. Infection...

Chicken infectious anaemia is a viral disease in young chickens which characterized by aplastic anaemia and immunosuppression. Between January 2004 and July 2005, an unusual hemorrhage in subcutaneous and intramuscular tissues of broiler chickens at slaughter houses of Mashhad, Isfahan and Tehran provinces were occurred. Postmortem examination revealed severe hemorrhages in the wings and muscle...
