Abstract

Avian Influenza (AI) is a zoonotic viral disease in birds which demands priority on control and measures. Spread of AI virus can occur directly or indirectly. The use of disinfectant and handling of hatching egg waste into one of the actions that must be applied in hatchery to control the spread of AI virus.  This research aim to compared two types of desinfectant in eliminating AI virus. The research was designed into 6 groups. Group I was SAN (Specific Antibody Negative) eggs as untreated negative control, group II was SAN egg treated by fumigation using potassium permanganate (KMnO4) and formalin in room temperature for 20 minutes, group III was SAN eggs soaked in benzalkolnium chloride (BKC) in room temperature for 30 seconds, group IV was SAN contaminated by AI H5N1 virus and fumigated by potassium permanganate and formalin in room temperature for 20 minutes, group V was SAN eggs contaminated by AI H5N1 virus and then soaked in benzalkonium chloride in room temperature for 30 second, and group VI was SAN eggs contaminated by AI H5N1 virus in room temperature for 10 minutes as positive control. AI H5N1 virus detection was done by using RT-PCR (Reverse Transcription Polymerase Chain Reaction) and confirmed by isolation in Embyronated Chicken Egg. The result of this research showed that the use of potassium permanganate  and formalin disinfectant gave little better performance compared to benzalkoniun chloride in eliminating AI H5N1 virus on hatching eggs.

Abstract

Paratuberculosis or Johne’s Disease is a granulomatous enteritis chronic disease of domestic and wild ruminants caused by infection of Mycobacterium avium subspecies paratuberculosis. The disease commonly infects dairy cattle with clinical signs of chronic diarrhea, decreasing body weight, low milk production, oedema, anemia and occasionally infertility. The basic procedure in order to control Paratuberculosis in farms is to do a good and proper handling of animal faecal. Disinfection of animal environments such as pens, faecal, sewerage and sewage are important in prevention of transmission of this disease. The purpose of this research is to determine specific disinfectan and dosage for Mycobacterium avium subspecies paratuberculosis decontamination in cattle feces so  it can be applied as disease control measures. Cows feces were contaminated with MAP 105CFU/ml and treated with ammonium quartener, phenolic and formaldehyde disinfectant doses 10%, 15% and 20%. The effectiveness of the disinfectant was tested based on MAP identification using Löwenstein-Jensen culture medium and nested Polymere Chain Reaction(PCR). The results showed 15% and 20% doses of formaldehyde disinfectants efective to decontaminate Mycobacterium avium subspecies paratuberculosis  in catle feces.

Abstract

Chronic Respiratory Disease (CRD) is a bacterial infection in chickens caused by Mycoplasma gallisepticum. CRD may result in economic loss in the livestock industry, decreasing of egg production and feed efficiency, increasing of  medication costs, downgrading of carcass and egg qualities. The aim of this study was to develop the Enzyme-Linked Immunosorbent Assay (ELISA) kit for detecting antibodies of M. gallisepticum using freeze-thawing antigens. The cut-off point was determined by S/N method. Chicken antiserum againts M. gallisepticum was collected every week on 1st – 6th week post immunization of whole cell antigen of M. gallisepticum. Optimization of antigen, serum and conjugate were 10 μg/ml protein concentrations, 1:800 serum dilution and 1:10000 conjugate dilution. The validation results on developed ELISA kit (MyGELISA) analyzed  by ROC curve using MedCalc statistical software revealed that developed ELISA kit (MyGELISA) had 100% sensitivity and 86.21% specificity with 95% confidence interval. The results of RSA, MyGELISA and commercial ELISA kit showed antibodies positif againts M. gallisepticum.  In conclusion, MyGELISA using freeze-thawing antigen can be used to detect antibodies of M. gallisepticum.
