Extranuclear basic proteins have been detected in the capsule of the spermatozoa of three species of decapod crustaceans (Nephrops norvegicus L., Macrura; Eupagurus bernhardus L., Anomura; Carcinus maenas Penn., Brachyura). Their properties have been studied by cytochemical methods. Their position inside the capsule of the spermatozoon has been specified with the aid of the electron microscope....

BACKGROUND Avian hepatitis E virus (HEV) infection is common in chicken flocks in China, as currently no measures exist to prevent the spread of the disease. In this study, we analyzed the effect of caged versus cage-free housing arrangements on avian HEV transmission. First, 127 serum and 110 clinical fecal samples were collected from 4 chicken flocks including the two arrangements in Shaanxi ...

It is commonly established that warm blooded animals are extremely vulnerable to the infectious coccidian parasite, Toxoplasma gondii. T. gondii can be transmitted poultry and livestock through ingestion of oocyst (fecal-oral), placenta (congenital toxoplasmosis) in livestock. Cattle, sheep, rabbits some most consumed Palestine. As for poultry, backyard chicken, caged turkeys birds. The aim pre...

Insulin-like growth factor-I (IGF-I) has been purified from chicken serum and sequenced. The peptide has eight amino acid substitutions when compared with human IGF-I: serinez6, leucine3*, histidine 39, histidinea, lysine4i, glutamine”, isoleucine@, and proline6’. Chicken IGF-I (cIGF-I) has been measured using a radioimmunoassay with a human IGF-I (hIGF-I) standard and an antibody raised agains...

The parenchymal cells recorded were dark chief, 21.33%; intermediate, 73.46% and light chief, 5.20% and their dimensions (in microns) were, 17.30 ± 4.49, 19.98 ± 4.15 and 850 ± 8.49, respectively, and mean of serum calcium was 49.66 mg/100 ml.

chicken anemia virus was detected by pcr in tissue samples collected from poultry flocks in gujarat,india. the vp1, vp2 and vp3 gene sequences of cav from anand, gujarat were obtained after cloning thepcr products in pdrive cloning vector. nucleotide sequence alignment with other cav sequencesdemonstrated overall identity of 95-98.8%, 98.8-99.8% and 98.8-100% for vp1, vp2 and vp3 regions,respec...

The ability of monoclonal antibodies (mAbs) to target specific antigens with high precision has led to an increasing demand to generate them for therapeutic use in many disease areas. Historically, the discovery of therapeutic mAbs has relied upon the immunization of mammals and various in vitro display technologies. While the routine immunization of rodents yields clones that are stable in ser...
