Antibiotics are used in poultry farms to enhance growth, feed efficiency and reduce diseases. However, their irrational and non-moderate using can cause serious problems for the consumer and the manufacturer. The aim of this study is to estimate antibiotics residues in poultry (chicken and turkey) tissues collected from broiler farms in Meknès Morocco. For this purpose, 120 poultry meat samples...

Shiga toxin-producing Escherichia coli (STEC) are food-borne pathogens primarily associated with the consumption of contaminated ground beef and are an important food safety concern worldwide. STEC has been found to produce a family of related cytotoxins known as Shiga toxins (Stxs). Shiga toxins have been classified into two major classes, Stx1 and Stx2. A single strains of STEC can produce St...

Campylobacter isolates from diverse samples within broiler production and processing environments were typed by using flaA short variable region DNA sequence analysis. Sixteen flocks from four different farms representing two broiler producers in Arkansas and California were analyzed. Fourteen of the flocks (87.5%) were Campylobacter-positive; two remained negative throughout the 6-week rearing...

Enterococci are now frequent causative agents of nosocomial infections. In this study, we analyzed the frequency and distribution of antibiotic resistance and virulence genotypes of Enterococcus isolates from broiler chickens. Fecal and cecal samples from nine commercial poultry farms were collected to quantify total enterococci. Sixty-nine presumptive enterococci were isolated and identified b...

Nanoparticles of silver were treaeted as clinical trials in some broiler farms for its disinfecting characters in 4 broiler farms during growing period. The nanosilver were used orally and inhalatory in amount of 2 -4 ppm and 40 ppm respectively. Some samples of Breast muscle, Femora muscle, Heart, Gizzard, Liver, Skin, Spleen, Lung, Kidney and Cloacal feces were collected randomly in slaughter...
