The haematological profile of female bronze turkeys (Meleagris gallopavo) vaccinated with various commercial strains of Newcastle disease.

The effects of vaccination on avian blood parameters are poorly understood. The present study was designed to evaluate whether different strains (Ulster 2C, B1, live LaSota and inactivated LaSota) of Newcastle disease vaccines had an effect on the haematological profile of female turkeys. Seventy-five female turkeys were allocated to treatment groups according to vaccination strain.

Hematology of the Red-capped parrot (Pionopsitta pileata) and Vinaceous Amazon parrot (Amazona vinacea) in captivity.

Preliminary reference intervals for hematologic and total plasma protein profiles were determined for nine adult Red-capped parrots (Pionopsitta pileata) (six males and three females) and six Vinaceous Amazon parrots (Amazona vinacea) (two adult males, two adult females, one juvenile, and one nonsexed) from the Curitiba Zoo, Paraná, Brazil. For both Red-capped parrots and Vinaceous Amazon parrots, adult males had higher red blood cell counts than adult females. Regarding white blood cell distribution, differences due to gender were also found for both species of parrots.

Experimental infection of Newcastle disease virus in pigeons (Columba livia): humoral antibody response, contact transmission and viral genome shedding.

The aim of this study was to evaluate the humoral antibody response, the genome viral excretion and the contact transmission of pathogenic chicken origin Newcastle disease virus (NDV) from experimentally infected pigeons (Columba livia) to in-contact pigeon. The antibody response to infection was assessed by the hemagglutination inhibition (HI) test and the genome viral excretion was detected by RT-PCR. Viral strain induced high antibody levels, both in inoculated and in sentinel birds.

The effects of ochratoxin/aluminosilicate interaction on the tissues and humoral immune response of broilers.

This study aimed to evaluate the effect of dietary ochratoxin, in the presence or absence of aluminosilicate, on the histology of the bursa of Fabricius, liver and kidneys, and on the humoral immune response of broilers vaccinated against Newcastle disease virus. The exposure of birds to 2 p.p.
