Most isolates of Toxoplasma gondii can be grouped into 3 genetic lineages. In the present study, 67 isolates of T. gondii were obtained by bioassay in mice inoculated with brains and hearts of 96 asymptomatic chickens from an area highly endemic to human infection in Rio de Janeiro, Brazil. Of the 48 isolates genotyped using the SAG2 locus, 34 (70%) were of type I and 13 (27%) were of type III....

Domestic chickens have long been important to human societies for food, religion, entertainment, and decorative uses, yet the origins and phylogeography of chickens through Asia remain uncertain. In this study, the complete mitochondrial (mtDNA) D-loop sequences were analyzed for a total of 27 individuals of Cambodia (n=13), Myanmar (n=6), Bangladesh (n=3) Red junglefowls (RJFs) and Laos native...

For economic and environmental reasons, chickens with superior feed efficiency (FE) are preferred in the broiler chicken industry. High FE (HFE) chickens typically have reduced abdominal fat, the major adipose tissue in chickens. In addition to its function of energy storage, adipose tissue is a metabolically active organ that also possesses endocrine and immune regulatory functions. It plays a...

Benda V.: Studies on the Cell-Mediated Immunity in Chickens Infected with Marek's Disease Virus. Acta vet. Brno, 47,1978: 197-201. The effect oflymphocytes from MDV -infected chickens on HCr-labelled HPRS line 1 Iymphoblasts derived from an from an MDV-induced lymphoma was investigated by using a cytotoxicity test (CTT). In comparison with the control and vaccinated chickens, chickens inoculate...

Abstract. Research objective was to study the intestinal microbiocenosis in broiler chickens. Laboratory test conducted at and Development Center for Agriculture of North-Western Branch Tyumen SB RAS. Methods. Cobb 500 chickens breed used. The main part experiment began age 14 days. By this time, had reached an average body weight 365 grams. control group fed basic diet, consisting total mixed ...

Chickens are considered one of the most important hosts in the epidemiology of Toxoplasma gondii infection because they are an efficient source of infection for cats that excrete the environmentally resistant oocysts and because humans may become infected with this parasite after eating undercooked infected chicken meat. The objective of this study is to review worldwide prevalence of T. gondii...

The role of mucosal antibody in recovery from a primary infection and resistance to reinfection with infectious laryngotracheitis (ILT) herpesvirus was studied in bursectomized chickens, which were unable to synthesize specific antibodies. Viral antigen in the infected trachea was assessed by indirect immunofluorescence on tissue sections and by ELISA. The ability of bursectomized chickens to r...

Results of isolation of glycopeptide-resistant enterococci from fecal samples of pigs and chickens were found to differ strongly depending upon the type and age of animals and isolation technique (direct selective plate or broth enrichment). Isolations were frequent in broiler chickens and in sows but rare in layer chickens.

Clinical toxoplasmosis in chickens (Gallus domesticus) has been rarely reported in literature. Here we report that three chickens on a farm in Illinois developed neurological signs. One of these chickens was examined postmortem and it had non-suppurative encephalitis with numerous Toxoplasma gondii tachyzoites and tissue cysts. The identity of the protozoa was confirmed immunohistochemically by...
