Haematological changes associated with haemorrhage were determined in the guinea fowl (Numida meleagris galeata, Pallas). The red blood cell, packed cell volume and mean corpuscular haemoglobin decreased significantly (p<0.05) at 4 h posthaemorrhage and returned to normalcy one week after hemorrhage. After 4 h of hemorrhage, the haemoglobin concentration also fell significantly (p<0.05). The fa...

The assessment of spermatozoa motility is one of the most often used parameters for semen evaluation. The study was conducted at Poultry Research Station, Madhavaram Milk Colony, Chennai600 051, to  nd the effect of different semen diluents and dilution ratio on per cent spermatozoa motility of pooled guinea fowl semen at 5o C under short term storage(0, 3 and 6 Hours). Irrespective of the sto...

A panel of monoclonal antibodies was generated against the guinea fowl's bursal cells. One of the antibodies, designated BoA1, recognized both cortical and medullary B cells of bursal follicles and B cell dependent regions of peripheral lymphoid organs, like germinal centers and splenic periellipsoidal regions. The staining pattern of this monoclonal antibody is similar to other antibodies (L22...

1. Of three species of mammals tested by peripheral inoculation (guinea pig, cat, and horse) none showed viremia under conditions which suggested that any of these species would serve as a frequent source of mosquito infection. 2. Of the birds tested (chicken, duck, and dove) all developed viremia and might readily serve as natural sources of mosquito infection. Chickens were shown to be very h...

The thymus gland is a lymphoid tissue derived from III and IV pharyngeal pouches. It is the source of stem cells that migrate to other lymphoid organs and participate in immune reactions (Kent, 1978). The thymus gland is regarded immunologically as a primary or central lymphoid organ and its presence is essential for the development of peripheral lymphoid tissues and their associated adaptive i...

Infectious bursal disease (IBD), caused by an Avibirnavirus, belonging to the family Birnaviridae, is immunosuppressive that affects 3–6-week-old chickens, resulting in clinical or subclinical infection. Although occurs turkeys, ducks, guinea fowl, and ostriches can be also infected. IBD virus (IBDV) causes lymphoid depletion of bursa, which responsible for severe depression humoral antibody re...

ALL TYPES of poultry are important reservoirs of paratyphoid infections. As applied to poultry diseases, the term ''paratyphoid" denotes diseases caused by micro-organisms of the Salmonella group other than Salmonella pullorum (puUorum disease) and Salmonella gallinarum (fowl typhoid). More than 60 of the 200-odd types of Salmonella that are known to exist cause diseases in poultry. With the ra...
