Abstract

The current study was designed to investigate pathological effects of fowl adenovirus in broilers exposed to aflatoxin B1. Fowl Adenovirus-4 (FAdV-4) infection is remerging in all types of poultry birds in Pakistan. Poultry feed contamination with mycotoxin (aflatoxin) is another important global issue. A total of 125-day old broiler birds were divided into six equal groups. Group A served as control. B and C groups were administered with aflatoxin B1 (AFB1) 100 and 200 μg/kg feed. Group D was infected with FAdV-4, while groups E and F administered with both AFB1 (100 & 200 μg/kg) along with FAdV-4. These birds were monitored for clinical signs and mortality. Feed intake, body weight (BW), relative organ weights and gross & histopathological lesions were recorded. The highest mortality was observed in group F (FAdV-4 + AFB1 200 μg/kg feed) and the lowest mortality was observed in group B (AFB1 100 μg/kg feed). Body weights of all the groups were significantly (p

Abstract

This study was planned and executed with the aims to explore corpus luteal primary cell culture as an “animal alternate testing system” in toxicity studies and in vitro toxic effects of cypermethrin (CY) 90% (pyrethroid) and methamidophos (MTP) 73% (organophosphate) on morphology and progesterone secretory activity of bovine corpus luteal cells and tissue. For this purpose, primary cell cultures of bovine corpus luteum (CL) cells were maintained in Dulbecco's Modified Eagle Medium (DMEM) supplemented with 5% fetal calf serum (FCS). Toxicity evaluation were based on viable CL cell counts, morphological changes in CL cells, ability of CL cells to produce progesterone and histological changes in CL tissue at different hours post exposure to CY and MTP. The changes induced by both the insecticides were time and dose dependant. Viable cell counts and progesterone concentration decreased significantly (P
