| prevalence of arbovirus antibodies in sera of animals in sri lanka. | the sera of cattle, goats, dogs and crows from the colombo area were tested for antibodies against seven arboviruses of the families togaviridae and bunyaviridae by a plaque-reduction neutralization microtest, using vero cells and a stable line of pig kidney (ps) cells. the overall percentages of positive sera among the mammals were: bhanja, 92.5%; calovo (batai), 30.6%; sindbis, 13.8%; langat, 4.8%; tahyna, 3.9%; west nile, 1.6%. among the birds, 23.8% had antibodies to bhanja virus and 9.5% to ... | 1983 | 6609014 |
| characterization of sri lanka rabies virus isolates using nucleotide sequence analysis of nucleoprotein gene. | thirty-four suspected rabid brain samples from 2 humans, 24 dogs, 4 cats, 2 mongooses, i jackal and i water buffalo were collected in 1995-1996 in sri lanka. total rna was extracted directly from brain suspensions and examined using a one-step reverse transcription-polymerase chain reaction (rt-pcr) for the rabies virus nucleoprotein (n) gene. twenty-eight samples were found positive for the virus n gene by rt-pcr and also for the virus antigens by fluorescent antibody (fa) test. rabies virus is ... | 2001 | 12083333 |
| serological examinations of dogs (canis familiaris) in colombo/sri lanka. | in colombo/sri lanka wild dogs were investigated for various zoonoses. based on the poor general conditions the contamination rate was relatively high. 27 of the 30 dog sera reacted positive against listeriosis. 17 of the 29 samples reacted against q-fever in low titers, however, because of the highly purified antigen used these are evaluated as positive. the contamination rate was 100%. 18 sera reacted positive against the rmsf-group antigen. 14 samples reacted positive against chlamydiasis. 17 ... | 1988 | 3169564 |
