Colibacillosis, caused by avian pathogenic Escherichia coli (APEC), is a significant disease, causing extensive animal and financial losses globally. Because of the significance of this disease, more knowledge is needed regarding APEC's mechanisms of virulence. Here, we present the fully closed genome sequence of a typical avian pathogenic E. coli strain belonging to the serogroup O78.

Escherichia coli is probably the most famous bacteria in broiler production .... Along with Mycoplasma, it is responsible for many economical losses (meat produced of antibiotics spent to fight against). Colibacillosis is indeed the most frequently reported disease in surveys of poultry diseases or condemnations at processing. Yogaratnam in 1995, for instance, showed that 43% of broiler carcass...

he 19 meeting of Asian Pacific Endodontic Confederation (APEC) was held from 5 till 8 of April, 2017 at Hotel Hyatt Regency, New Delhi, India encompassing more than 1900 participants from 40 countries. The theme of the congress was "Preserve to Stillness" “An endodontist is the cardiac and neurosurgeon for the tooth. No other specialty involves as much focus, depth of involvement or may we say,...

colibacillosis caused by avian pathogenic escherichia coli (apec) is an economic threat to the poultry industry throughout the world. some of the virulence genes may enhance the ability of e. coli isolates to grow in the tissues of broilers. the apec strains are assigned to a few distinct phylogenetic groups. the purpose of the present study was to detect the virulence genes and phylogenetic gr...

Although research has increasingly focused on the pathogenesis of avian pathogenic Escherichia coli (APEC) infections and the "APEC pathotype" itself, little is known about the reservoirs of these bacteria. We therefore compared outbreak strains isolated from diseased chickens (n = 121) with nonoutbreak strains, including fecal E. coli strains from clinically healthy chickens (n = 211) and stra...

Avian pathogenic Escherichia coli (APEC) cause severe respiratory and systemic disease in poultry yet the nature and consequences of host immune responses to infection are poorly understood. Here, we describe a turkey sub-acute respiratory challenge model and cytokine, cell-mediated and humoral responses associated with protection against homologous re-challenge. Intra-airsac inoculation of tur...

The present experiments tested the hypothesis that adenosine A2 receptors are involved in central reward function. Adenosine receptor agonists or antagonists were administered to animals that had been trained to self-stimulate in a rate-free brain stimulation reward (BSR) task that provides current thresholds as a measure of reward. The adenosine A(2A) receptor-selective agonists 2-p-(2-carboxy...

Aim Avian pathogenic Escherichia coli (APEC) is pathogenic strains of E. coli that are responsible for one of the most common bacterial diseases affecting poultry worldwide. This study was designed to determine the occurrence, antibiotic resistance profile, and antibiotic resistance genes of E. coli isolated from diseased and freshly dead broilers. Materials and Methods In that context, a tot...

Autotransporters are secreted bacterial proteins exhibiting diverse virulence functions. Various autotransporters have been identified among Escherichia coli associated with intestinal or extraintestinal infections; however, the specific distribution of autotransporter sequences among a diversity of E. coli strains has not been investigated. We have validated the use of a multiplex PCR assay to...

Avian pathogenic Escherichia coli is an important pathogen causes systemic infections in avian species and large economic losses in poultry industry worldwide. The functional role of porins during the infection and their mechanisms of interaction with host tissues for adhesion to and invasion are poorly understood. However, whether porins play a role in infection remains unclear. In this study ...
