Sensitivity of Escherichia coli 0157:H7 Strain 932 to Selected Anticoccidial Drugs in Broiler Chicks

Effect of Experimental Yolk Sac Infection with Escherichia Coli on Immune Status of Broiler Chicks

In this study, 100 day-old broiler chicks were divided into two groups, A and B containing 50 birds each. Experimental infection with E. coli was given intra yolk to group A on day-1 of experiment, while group B was kept as control. Parameters studied were examination of yolk sac, yolk sac:body weight ratio, antibody titer against Newcastle disease virus (NDV) and analysis of fractional serum p...

Isolation, Identification and in vitro Susceptibility of Avian Escherichia coli to Selected Fluoroquinolones

Loci for radiation sensitivity in Escherichia coli strain Bs-1.

TRAIN B,-, is a mutcnt of Escherichia coli strain B, isolated and described by HILL and SIMSON (1961), having the following properties: it is extremely sensitive to ultraviolet (UV) radiation; does not, like parent strain B, form filaments following UV irradiation; is less efficient than strain B at reactivating certain UV irradiated coliphages (HCR-) ; cannot excise UV induced thymine dimers f...

Antibiotic Sensitivity Patterns of Escherichia coli Isolated in Urine Samples of Patients Referred to Ayatollah Mousavi Hospital in Zanjan

Background & Objective: Escherichia coli (E. coli) is considered to be the most common cause of urinary tract infections (UTIs) worldwide. Due to the recent rise in bacterial resistance to antibiotics and the appearance of multidrug-resistant E. coli, treatment options have been significantly limited, thus increasing the cost of treatment as well as morbidity and mortality rates, especially in ...

Corn expressing an Escherichia coli-derived phytase gene: residual phytase activity and microstructure of digesta in broiler chicks.

The residual phytase activity, phytic acid P content, and microstructure of the digesta along the gastrointestinal tract (GIT) of broiler chickens fed a corn expressing microbial phytase was studied in a 14-d experiment. The phytase activity of the corn expressing phytase (CBP) was determined to be 660 phytase units/g and was incorporated into broiler diets at varying rates. One hundred forty-f...
