187 commercial checken flocks affected with respiratory diseases were examined for ornithobacterium rhinotracheale isolation. the bacterium was isolated from 105 (56.2%) poultry flocks. drug sensitivity test using standard disk diffusion technique was performed with 19 antibiotics. all the isolates were susceptible to tiamulin and most of them were susceptible to chloramphenicol and linco-spect...

Saprolegnia ferax contains an integrin homologue, identified by crossreactivity with antiserum to the consensus sequence of human/chick/Xenopus cytoplasmic domain beta 1-integrin, which is highly conserved. In non-reduced samples, this integrin was larger than the reported size range for beta 1-integrins, at 178 kDa. In reduced samples, there was a reducing agent-concentration-dependent convers...

After equilibrating cells with [32P]phosphate there were 3.7 f 0.2 mol of [32P]phosphate/mol of Band 2 subunit; this is the total measured as nonradioactive phosphate in fresh cells (Harris, H. W., Wolfe, L. C., and Lux, S . E. (1978) Fed Roc. 37, 1507). This level can be reduced in intact cells by metabolic depletion, or on purified spectrin by tryptic removal of the terminal phosphorylated pe...

The life threatening anemia in beta-thalassemia major (Cooley's anemia) is characterized by profound intramedullary lysis, the cause of which is incompletely understood. Using marrow obtained from beta thalassemia major patients undergoing allogeneic bone marrow transplantation in Pesaro Italy, it became possible to directly study the mechanism of the intramedullary hemolysis. Based on our prev...

This study was conducted on a commercial New Zealand sheep farm in order to compare the cure rates of merino sheep infected with footrot. Infected sheep were treated with either lincomycin/spectinomycin combination (Linco-Spectin soluble powder, Pfizer Animal Health) or tilmicosin (Micotil 300 Injection, ELANCO) antibiotics. A flock of 3000 mixed age merino ewes had their feet inspected by the ...

Problem statement: Escherichia coli isolates are the most common bacterial agents of salpingitis in commercial layer hens. The objectives of this study were to determine the phylogenetic groups/subgroups and antibiotic resistance of E. coli isolates from salpingitis cases in commercial layer hens farms in southeast of Iran. Approach: One hundred twenty one E. coli isolates from oviducts of laye...
