Studies On The Isolation And Serotyping Of Salmonella From Faecal Material Of Buffaloes

by Rashid, M | Muhammed Ajmal | Mubasher | S. Ata-Ur- Rehman Rizvi | Faculty of Veterinary Sciences.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 1987Dissertation note: Health of human population alongwith animals is always at risk when Salmonella shedding carriers are present. The modern trend of Farm industry makes it more important to look out for the carriers and treat them to save the other animals and man from Salmonellosis. The present work Was under-taken to determine the Salmonella carrier state in healthy buffaloes, in an attempt to understand the epidemiological role played by these animals in the transmission of Salmonella infection to other animals and man. The faecal samples. were collected from 1000 animals. A series of enrichment, selective and differential media, biochemical& 6ro1ogy teste were used for isolation,iden- tification and serotyping of Sa.iionella from the faecal specimens. It was observed that 18 animals out of 1000(1.8%)were carrier of Salmonella. Salmonella typhimurium was isolated from 12 cases while Slamonella butantan was isolated from 6 cases. Occurrence of Salmonella typhimurium and Salmonella butantan are important from Veterinary Public Health point of view.

Role Of Maternal Antibodies In Protection Against Infectious Bursal Disease (Ibd) In Commercial Broilers

by Zaheer Ahmad | Muhammed Akram Muneer | s. Ata-ur-Rehman Rizvi | Faculty of Veterinary Sciences.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 1992Dissertation note: In this study, the decay rate of maternal antibodies to infectious bursal disease virus (IBDV) protective efficacy of maternal antibodies to experimental IBDV challenge and the protective efficacy of a live IBD virus vaccine (Bursine 11) to I8DV experimental challenge were studied. Enzyme Linked Immunosorbent 1ssay (ELISP) was standardized and performed to analyze the serum samples. The level of maternal antibodies to (IBDV) was found to be positive till the fourth week of age. The line of best fit to this decay rate within the study period was found to be Y=0.43-O.O53 (week) and has the coefficient of determi- nation 0.904. The positive level of maternal antibodies after second week of age were found insufficient to protect broiler chicks against the IBDV challenge. Maximum mortality (207.) was observed after experimental IBDV challenge at 35 days of age in broiler chicks. This suggested that the offsprings need to be vaccinated with the live IBD virus vaccine before that age. The maternal antibodies were demonstrated to interfere with the live vaccination. vaccination. Live virus at 14 days of age were found to be protective and a booster with the same vaccine in the fifth week of age prevented the chicks from infection.

Studies On Avian Pasteurolosis, Characterization Of Isolates From Diseased Carrier Birds

by Tanveer Afzal | Sheikh Muhammed Amin | S Ata-ur-Rehman Rizvi | Faculty of Veterinary Sciences.

Material type: book Book; Format: print Publisher: 1992Dissertation note: A total of 1000 birds (600 diseased/dead and 400 healthy) were examined for the isolation of the Pasteurelia muitocida so as to have an idea about the incidence of fowl cholera in the poultry flocks (Broiler and Layer) and the percentage of the carriers for the organism maintiined in and around Lahore. Out of 600 diseased/dead birds examined 1% yielded Pasteurella inultocida. None of the 400 healthy birds proved carrier for organism. All the six isolates produced small, greyish, circular colonies on blood agar. The growth in the Triptic Soya agar appeared in the form of convex, entire edged, mucoid colonies having a diameter of ljim. There was not any growth on MacConkey agar. All the isolates fermented glucose, sucrose, mannose, mannitol, xylose and fructose with production of both, acid and gas. Likewise all the six isolates were positive for nitrate reduction, catalase/reduction, indole production H2sproduction nitrate reduction tests. None of the isolates was positive for gelatin liquification methyl red test, voges-Proskauer test, and urease production test. All the isolated organisms were non-motile. All the isolates proved pathogenic to mice. Antibitics including chloramphenicol, Gentamicin Furadantin, Streptomycin and Nalidixic acid were highly effective against all the isolated strains. However the isolates were insensitive to Tetracycline and Erythromycin. Availability: Items available for loan: UVAS Library [Call number: 0325,T] (1).
