studies of experimental jembrana disease in bali cattle. i. transmission and persistence of the infectious agent in ruminants and pigs, and resistance of recovered cattle to re-infection.the agent causing jembrana disease, an enzootic disease of bos javanicus (bali cattle) occurring in bali, indonesia, was shown to occur at high titres in the blood of animals during the febrile period of the disease and to persist in cattle for 25 months after clinical recovery. during the febrile period of the disease, most of the infectious agent appeared to be associated with the plasma fraction of whole blood. there was a linear relationship between the number of organisms inoculated into su ...19902394846
studies on experimental jembrana disease in bali cattle. ii. clinical signs and haematological changes.the clinical and haematological changes which occurred in 18 bali cattle (bos javanicus) experimentally infected with jembrana disease are described. the major clinical signs were an elevated rectal body temperature persisting for 7 days (range 5 to 12 days), lethargy, anorexia, enlargement of the superficial lymph nodes, a mild ocular and nasal discharge, diarrhoea with blood in the faeces and pallor of the mucous membranes. not all of these changes occurred in all affected cattle. the major ha ...19902394847
the transmission of jembrana disease, a lentivirus disease of bos javanicus cattle.methods of transmission of jembrana disease, an acute and severe disease of bali cattle (bos javanicus) caused by a recently-identified bovine lentivirus known as jembrana disease virus, are described. during the acute disease virus can be detected in saliva and milk. there is evidence of direct transmission from acutely affected animals in close contact with susceptible cattle, possibly by virus in these secretions infecting cattle by the conjunctival, intranasal or oral routes, by which it was ...19957589275
recent advances in the understanding of jembrana disease.jembrana disease is a severe and acute clinical disease in bali (bos javanicus) cattle with a case fatality rate of about 20%, and a mild sometimes subclinical disease in other cattle types and buffalo. the aetiological agent has been identified as a lentivirus, designated as jembrana disease virus (jdv). preliminary sequence analysis has confirmed the identity of jdv as a lentivirus and has shown that it is distinguishable from biv. there is antigenic cross-reactivity between the capsid protein ...19958545963
sequence analysis of jembrana disease virus strains reveals a genetically stable lentivirus.jembrana disease virus (jdv) is a lentivirus associated with an acute disease syndrome with a 20% case fatality rate in bos javanicus (bali cattle) in indonesia, occurring after a short incubation period and with no recurrence of the disease after recovery. partial regions of gag and pol and the entire env were examined for sequence variation in dna samples from cases of jembrana disease obtained from bali, sumatra and south kalimantan in indonesian borneo. a high level of nucleotide conservatio ...200717433486
on the origin of indonesian cattle.two bovine species contribute to the indonesian livestock, zebu (bos indicus) and banteng (bos javanicus), respectively. although male hybrid offspring of these species is not fertile, indonesian cattle breeds are supposed to be of mixed species origin. however, this has not been documented and is so far only supported by preliminary molecular analysis.200919436739
seroprevalence of antibodies to neospora caninum in bos javanicus ('bali cattle') from indonesia.a cross-sectional survey was performed to obtain first information on the presence of neospora caninum infection in bos javanicus ('bali cattle'), the predominant beef cattle in the eastern islands of indonesia. serum samples were collected from 438 bali cattle of two age classes (<2 years, >2 years) and both genders at three slaughterhouses in the bali island, and examined for n. caninum-specific antibodies using native ncsrs2 (p38 antigen) as an elisa antigen. the estimated overall seroprevale ...201019533406
the origin of indonesian cattle and conservation genetics of the bali cattle breed.both bos indicus (zebu) and bos javanicus (banteng) contribute to the indonesian indigenous livestock, which is supposedly of a mixed species origin, not by direct breeding but by secondary cross-breeding. here, the analysis of mitochondrial, y-chromosomal and microsatellite dna showed banteng introgression of 10-16% in indonesian zebu breeds with east-javanese madura and galekan cattle having higher levels of autosomal banteng introgression (20-30%) and combine a zebu paternal lineage with a pr ...201222212207
immunopathology of experimental jembrana disease in bali cattle.sequential immunohistochemical studies of the lymphoreticular responses of bali cattle (bos javanicus syn. bos sondaicus) after inoculation with the jembrana disease virus were carried out using the peroxidase-antiperoxidase test for immunoglobulin containing cell assessment and the indirect immunoperoxidase test for lymphocyte subset assessment. the prevalence of immunoglobulin g-containing cells declined during the acute phase of the disease but became significantly elevated during convalescen ...19947725629
vascular lesions in lungs of bali cattle with jembrana disease.jembrana disease is an acute infectious disease of unknown etiology enzootic among bali cattle (bos javanicus) in indonesia. morphologic examination of 75 female bali cattle between 18 months and 4 years old affected with jembrana disease consistently revealed pulmonary granulomatous vascular lesions. the lesions were diffusely distributed throughout the lung. the principal lesion was the presence of a large number of intravascular macrophages that filled the lumina of pulmonary veins and pulmon ...19921621332
banteng and bali cattle in indonesia: status and forecasts.bali cattle still represents 27% of the total cattle population in indonesia, and it is considered the pillar breed for small farmers. moreover, it is a breed of evolutionary importance regarding its direct ancestry from banteng. however, there is a need for the establishment of a rational system for the evaluation of breeding soundness for indigenous bali bulls to be used as sires for artificial insemination breeding programmes. moreover, there is a need for cryobanking of well-identified genet ...201222212203
flow cytometric analysis of lymphocyte subset kinetics in bali cattle experimentally infected with jembrana disease virus.jembrana disease virus (jdv) is an unusual bovine lentivirus that causes an acute and sometimes fatal disease after a short incubation period in bali cattle (bos javanicus). the pathological changes occur primarily in lymphoid tissues, which feature proliferating lymphoblastoid-like cells predominantly throughout parafollicular (t-cell) areas, and atrophy of follicles (b-cell) areas. five bali cattle were experimentally infected with jdv and all developed typical clinical signs of jembrana disea ...201222776774
distribution of jembrana disease in cattle in enzyme-linked immunosorbent assay (elisa) was used to detect antibodies to jembrana disease virus in sera of cattle in indonesia. antibodies were detected in cattle from bali island and some districts of lampung (sumatra), west sumatra and east java provinces but not in other areas of indonesia. clinical jembrana disease or jembrana-like diseases have been reported to occur in bali cattle (bos javanicus) in all four areas where antibody was detected and not in the other areas where antibody w ...19938128600
