BookPublisher: 2006Subject(s): Department of MicrobiologyDDC classification: 0966,T Dissertation note: Poultry sector is the second largest industry after textile in Pakistan. It is threatened by various diseases i.e; Newcastle disease (ND), Avian Influenza (Al), Colibacillosis, Hydro-pericardium syndrome (HPS) and Infectious bursal disease (IBD, Gumboro). The efficacy of various available disinfectants (Hygen 275 — 2000 H, Virkon S and Aldekol) was tested at 2x, lx and Y2 x dilution against Staphylococcus aureus, Escheria Coil, Newcastle Disease virus and Avian Influenza virus. Each dilution of all the disinfectant was divided into 4 aliquots i.e; a, b, c and d (each of the
aliquot, for each pathogen). Each aliquot were mixed with equal volume of either of the pathogen. The mixture of the disinfectant and the pathogen was incubated at 37°C for a period of 15, 30 and 45 minutes of interaction. The contents were collected aseptically and processed to evaluate the effectiveness of the disinfectants. Disinfectant A (Hygen 275-2000H) showed good bactericidal as well as virucidal activity at 1% dilution. Disinfectant B (Virkon S) was able to kill all the bacteria and viruses even at 0.25 % dilution. While, disinfectant C (Aldekol) effectively killed the bacteria and viruses at 0.5 % and I % dilutions. Results of the study will help the farmers to adopt effective biosecurity measures to minimize the challenges at farm level.
