Abstract

Marek’s is a limphoproliferative and oncogenic disease of poultry caused by a serotype 1 herpesvirus.  Chicken  between 10 and 15 weeks of age are the most susceptible although in some outbreaks it also affects other ages. The causal agent consists of  some  virus  strains  with  different  pathotypes  causing  a  variety  of  clinical  and  pathological manifestations. The  main pathological features are neurological lesion and lymphoma formation in some visceral organs. Marek’s disease is clinically classified as classical, acute, peracute and chronic with neurological disorder and superficial tumor. At necropsy the peripheral nerves were enlarged, discoloured and loss of striation. There were formation of lymphoid tumour in various visceral organs. Microscopically Marek’s produced non suppurative encephalitis/neuritis and pleomorphic tumour. The diagnosis is based on the history of the disease, age of affected chicken, clinical and pathological features. A definitive diagnosis is made by virological and serological tests. Some of the Marek’s cases in Indonesia were discussed in this paper, as well as review on clinico- pathological aspects how to confirm the diagnosis of Marek’s.   Key words.

Abstract

Thirty rabbits were used in this study: 22 were infected and eight were used as controls . Fourteen rabbits were inoculated with blood taken from Ongole (Bos indices) cattle or buffalo naturally infected with malignant catarrhal fever (MCF). Another eight rabbits were inoculated with lymphoblastoid cell liras which contain Ovine Herpesvirus-2 (OHV-2), the causal agent of sheep-associated MCF. Various degrees and distributions of histological changes were observed and resembling the lesions developed in MCF. However 17 infected rabbits (77.3%) with non-suppurative meningoencephalitis, eight of them (47.196) were associated with the detection of Encephalhozoon cuniculi histologically .

Abstract

A study was carried out to detect the phenotype ofT cell subsets in six Bali cattle affected with malignant catarrhal fever (MCF). This was performed by means of immunohistochemical technique using avidin-biotin-peroxidase complex methods. Seven monoclonal antibodies against lymphocyte surface antigen were used to detect T cell subsets ie . CD1, CD2, CD4, CD5, CD8, CD45, and WC 1. The results showed that the subsets were all detected either in the MCFor non-MCF infected Bali cattle lymph nodes. However, CD8 was more predominantly occupied in the MCF Bali cattle . This indicated that CD8 was a cytotouic Tlymphocytes and acted as potential mediators for immunopathological process in MCF.   Keywords : Malignant catarrhal fever, Tlymphocyte subsets, Bali cattle, immunohistochemical technique

Abstract

A study was carried out to detect the antigen of infectious bronchitis vius (IBV) in broiler chicken by means of immunohistochemical technique. A total of 150 - fourteen days old broiler chicken were divided into three groups i.e. 50 chicken were infected with an IB isolate of I-269, 50 chicken were injected with H-120 life vaccine, and 50 chicken served as un-treated control. Clinical signs and gross pathological changes were observed. Each of five chicken of each group were necropsied at 1, 2, 3, 4, 7, 10, 14, 21, 28, and 35 day(s) post infection/vaccination. The antigen could be detected at one day through 35 days post vaccination/infection. In the vaccinated group, histopathological lesions and the detected antigen were minimal. In contrast, the infected chicken showed varied histolopathological lesion in accordance with the numerous antigens. The antigen were observed in the lymphocytes/macrophages in the trachea, lungs and kidney, and in the epithelium of trachea, alveoli, broncheolus and tubular sitoplasm of the kidney of both vaccinated and infected groups. In the infected group, antigen was also detected in the lymphocytes and macrophages of the affected organs.   Key words: Infectious bronchitis, broiler chicken, I-269 IB isolate, immunohistochemistry

Abstract

A study to gain seroepidemiological feature and histopathological changes in order to obtain a viral causative agent had been conducted against parainfluenza virus type 3 (PI-3) in infection cattle in Indonesia. Serological survey was conducted in different areas in Indonesia and from serum Bank to gain the information on the distribution of parainfluenza type 3 (PI-3) in large ruminants. A total of 1334 sera had been tested using serum neutralization test, and the result indicated that prevalence of reactors was varied from 0 to 60 %. The highest prevalence was 60% in sera detected from Bogor abbatoir. Reactors were also found in other areas such as West Java, Central Java, East Java, NTT and Papua. Titration results indicated that the distribution of titre was varied from 4 to 256, and titre of 8 to 32 was the most common. Titre of 128 and 256 was only found in each of 1 sera only. Isolation results indicated that no isolate was obtained from 237 samples processed. Histological examination showed that more than 60% had interstitial pneumonia, which indicated vairal infection had been occurred. This serological result indicated that PI-3 infection was detected in Indonesian large ruminants.   Key words: Parainfluenza type 3 virus, serology, histopathology

Abstract

Monitoring on the cases of Avian Influenza virus was conducted by detecting viral antigen subtype H5N1 usingimmunohistochemical technique. A total of 212 sampels of various avian tissues were collected from the Provinces of East Java(Districts of Madiun, Tulung Agung, Blitar and Kediri), West Java (Districts of Bogor, Bekasi, Cianjur and Sukabumi), Banten(Districts of Pandeglang and Tangerang) and DKI Jakarta. The sampels were collected four times i.e. June 2004, September2004, October 2004 and between January and February 2005. All sampels were stained using immunohistochemical technique.The antigen could be visualized clearly both in the intra-nuclear and intra-cytoplasmic areas of brain, comb, wattle, trachea,lung, heart, breast and thigh muscle, proventriculus, liver, spleen, kidney, intestine and ovary. A number of 39 of 212 cases(18.4%) have been catagorized as positives. The results show that monitoring of HPAI cases conducted in June and September2004 in the Provinces of West Java, Banten and East Java, none of the sampels were positive. However, monitoring of thedisease in September 2004 in the Province of Jakarta showed that AI virus antigen were detected in various organs of chickenfrom Jakarta. Furthermore, monitoring of the disease conducted between October 2004 and February 2005 revealed that AI virusantigen were also detected in chicken not only from Jakarta Provinces but also from Provinces of Banten and West Java. Basedon these results, it is concluded that between June and September 2004, HPAI infection were not found in areas where previousoutbreaks occured in the Provinces of Banten, West Java and East Java. However, the disease was spread in Jakarta Province inSeptember 2004 and subsequently to some districts in the Provinces of Banten and West Java. A part from this, anticipation ofdisease spread to currently AI-free areas should be considered as part of disease monitoring system.Key Words: Avian Influenza, H5N1, Monitoring, Immunohistochemistry, Poultry

Abstract

pregnant sheep and lambing sheep were conducted in two different periods and flocks of Bali cattle and sheep. On the basis of clinico-pathological findings and polymerase chain reaction (PCR) tests, the study revealed that MCF transmission has been successfully achieved in four Bali cattle that were in contact with lambing sheep, and in one Bali cow that was penned 100 metres away from lambing sheep pen. The polymerase chain reaction (PCR) detected the causal agent of MCF in peripheral blood leucocytes (PBL) and nasal, ocular and vaginal secretions of sheep. It is assumed that viruses in the secretion were spread by sheep causing five Bali cattle suffered with MCF. However, further studies on exact mode of transmission needs to be clarified particularly on the time and mode of viral transmission from reservoir to susceptible animals.   Key words : Malignant catarrhal fever, experimental transmission, in-contact, Bali cattle, sheep
