A retrospective study on anthrax in endemic area was carried out from 1984 to 1994 in West Nusa Tenggara Province (NTB) to uncover the occurrence of anthrax and the pattern of the disease in livestock. Data of anthrax incidence had been compiled for the 11 years from Animal Health Section and Type B Laboratory of the Livestock Service Office, NTB Province in Mataram. This was done to get the information about locations and times when the cases occurred, and the vaccination status of livestock in the anthrax area. The pattern of anthrax in livestock was analyzed by using time series analysis, and the long term trend was then illustrated by linier regression . During the years, anthrax cases in livestock were reported high in Sumbawa island, while the cases in Lombok island were relatively low. There were no anthrax cases reported from East Lombok District . The long term trend of anthrax occurrence in livestock from 1984 to 1994 tended to decrease (Y= 6,04 - 0,0162 X). Â Keywords: Anthrax, cases pattern, retrospective study

Seroprevalence studies of HPAI H5 subtype in ducks and muscouvy duck in smallholders farm was carried out in Serang and Tangerang District, Banten Province. The study comprised a serological survey to define the distribution and prevalence of HPAI H5 subtype infection on ducks and muscouvy ducks as well as attempted isolation of the virus from these species. Unit of sample in each stage was randomly choosen by multy stage random sample. Blood samples were taken from ducks and muscouvy ducks that had never been vaccinated, purposively. Sera were tested using Haemaglutination Inhibition Test, antigen H5N1 (clade 2.3.2), while the cloaca and trachea swab samples was injected into specific pathogens free (SPF) embryonated 9-11 days old, to isolate the virus. Results showed that H5 subtype virus could be isolated from tracheal swabs of ducks in the various age groups. The seroprevalence of H5 subtype virus in Banten Province was 25.5%, in which, 24.3% occured in ducks and in muscouvy duck in the rate of 1.2%, with titer HI positive was > 3log2. Based on species, seroprevalence level HPAI H5 subtype in ducks was 3-4 times higher than the level of seroprevalence of HPAI H5 subtype in muscouvy duck, which indicated that the H5 subtype virus more likely to circulate in the ducks flock than in muscouvy duck. This study noted that both muscouvy duck and ducks appeared to play a significant role in the epidemiology of the disease. Key Words: Seroprevalence, Ducks, Muscouvy Duck, HPAI H5 Subtype

Stunting or runting syndrome in broiler chickens and its pathological changes Wahyuwardani, S; Sani, Y; Parede, L; Syafriati, T; Poeloengan, M
Indonesian Journal of Animal and Veterinary Sciences Vol 5, No 2 (2000)
Publisher : Indonesian Animal Sciences Society

A disease with stunting or runting syndrome in broiler chickens was investigated in 13 districts of West Java and Central Java provinces. A total of 291 chickens samples both with clinically stunted or runted were collected from 37 poultry farms. Blood samples were collected randomly from chickens in poultry farms for packed cells volume analysis. Tissues of liver, spleen, thymus, proventriculus, ventriculus intestines, caecum, pancreas, bursa fabricious and heart were collected for histopathological examination. Field surveys showed that prevalence rate of stunting or runting syndrome was varied from one farm to others between 0,1% to 50%. Clinical signs were noted as ununiformity of body size in a flock of chicken, stunted and/or runted of body weight gain and protrude of wing feather. Pathologic changes were hyperemic thymus, athropic thymus and athropic pancreas. While microscopically included dilatation crypt of Lieberkuhn, inflammation of thymus, pancreatitis and enteritis variably among each locations. The PCV level did not show direct link to the affected stunting or runting syndrome. Â Key words: Syndrome, stunting, runting, pathology anatomy, histopathology
