A total of 318 Escherichia coli isolates obtained from different food-producing animals affected with colibacillosis between 2001 and 2006 were subjected to phylogenetic analysis: 72 bovine isolates, 89 poultry isolates and 157 porcine isolates. Overall, the phylogenetic group A was predominant in isolates from cattle (36/72, 50%) and pigs (101/157, 64.3%) whereas groups A (44/89, 49.4%) and D ...

Extraintestinal pathogenic Escherichia coli (ExPEC) are major players in human urinary tract infections, neonatal bacterial meningitis, and sepsis. Recently, it has been suggested that there might be a zoonotic component to these infections. To determine whether the E. coli contaminating retail poultry are possible extraintestinal pathogens, and to ascertain the source of these contaminants, th...

Extraintestinal pathogenic Escherichia coli (ExPEC) strains are important pathogens that cause diverse diseases in humans and poultry. Some E. coli isolates from chicken feces contain ExPEC-associated virulence genes, so appear potentially pathogenic; they conceivably could be transmitted to humans through handling and/or consumption of contaminated meat. However, the actual extraintestinal vir...

Different studies on animals in around the world show that there are multiple-drug resistance in strains of Escherichia coli (E. coli). Such microorganisms are notorious for the extension of colibacillosis in poultry, which great economic losses bring for the poultry industry. This study was carried out to determine drug resistance and resistance factor transfer in E. coli strains isolated from...

Bacteriophage phAPEC8 is an Escherichia coli-infecting myovirus, isolated on an avian pathogenic Escherichia coli (APEC) strain. APEC strains cause colibacillosis in poultry, resulting in high mortality levels and important economic losses. Genomic analysis of the 147,737-bp double-stranded DNA phAPEC8 genome revealed that 53% of the 269 encoded proteins are unique to this phage. Its closest re...

This study was designed to compare the efficacy of a phytobiotic containing a mixture of essential oils of Oreganum aetheroleum and an antibiotic containing ciprofloxacin as an active principle for the treatment of experimental Escherichia coli (E. coli) infection in broiler chickens. Two-hundred-day-old broiler chickens were divided into 5 equal groups. The 1st group was neither challenged nor...

The challenges posed by microbes in poultry industries and the continued search for natural means of combating them inspired this study. effect stem bark extracts Anacardium occidentale on avian colibacillosis was investigated. Ethanol aqueous A. were prepared using standard methods. In vitro antimicrobial activities evaluated against E. coli. Nine groups 10 broilers (day old chicks; 48 g – 50 ...

Heat stress and exhaustion is one of the top causes of chicken death. For those new to backyard chicken farming, it is important you learn to recognize the signs of this serious condition and how to keep your chickens cool and hydrated. Chicks, especially, need extra attention to help them remain healthy. For a flock of laying hens, knowing how to prevent heat exhaustion and treat a chicken suf...
