| serologic evidence for an epizootic dengue virus infecting toque macaques (macaca sinica) at polonnaruwa, sri lanka. | dengue is one of the most rapidly emerging diseases in the tropics. humans are the principal reservoir of dengue viruses. it is unclear if nonhuman primates also serve as a reservoir of human dengue viruses under certain conditions. in this study, a cross-sectional serologic survey was carried out to characterize the pattern of transmission of a recently identified dengue virus among toque macaques in sri lanka. the results indicated that an epizootic dengue virus was active among the macaques. ... | 1999 | 10072155 |
| seroprevalence of toxoplasma gondii in wild toque macaques (macaca sinica) at polonnaruwa, sri lanka. | from a natural population that inhabits the dry evergreen forest at polonnaruwa, serum samples of 170 toque macaques were examined for antibodies to toxoplasma gondii by the modified agglutination test. of these, 21 (12%) were found with titers of 1:16 in 9, 1:32 in 9, 1:256 in 1, 1:1,024 in 1, and 1:4,096 in 1. there was no evidence of maternal transmission of antibodies or congenital toxoplasmosis. none of the infected macaques died within 1 yr after sampling. toxoplasma gondii infection was c ... | 2004 | 15357087 |
| hematology of a natural population of toque macaques (macaca sinica) at polonnaruwa, sri lanka. | hematological studies were conducted in three wild groups of toque macaques (macaca sinica) inhabiting the polonnaruwa sanctuary in northeastern sri lanka. the macaques were temporarily trapped and anesthetized, and femoral blood was drawn from 35 males and 37 females (age range: 0.33-24.5 yr). statistically significant (p<0.05) differences were observed by sex for total plasma proteins (pp), and by age for red blood cell (rbc) counts, hemoglobin (hb), mean corpuscular volume (mcv), mean corpusc ... | 2003 | 12966516 |
| paternity assessment in wild groups of toque macaques macaca sinica at polonnaruwa, sri lanka using molecular markers. | genetic variation at four microsatellite loci in conjunction with that at a highly variable allozyme locus was used to analyse paternity over a 12-year period in 13 social groups of toque macaques macaca sinica inhabiting a natural forest in polonnaruwa, sri lanka. paternity exclusion analysis revealed that the set of offspring produced by a female usually consists of half-siblings because few males father more than one offspring with a particular female. no evidence of offspring produced by mat ... | 1997 | 9076981 |
| the local distribution of highly divergent mitochondrial dna haplotypes in toque macaques macaca sinica at polonnaruwa, sri lanka. | surveys of mitochondrial dna (mtdna) variation in macaque monkeys have revealed extremely high levels of intraspecific divergence among haplotypes. one consistent pattern that has emerged from these studies is that divergent haplotypes are geographically segregated so that sampling a few matrilines from a given region shows them to be identical, or a closely related subset of haplotypes. geographically structured mtdna variation has also been commonly observed in other taxa. in this study, haplo ... | 1994 | 7952326 |

| seroepidemiology of dengue and other arboviruses in a natural population of toque macaques (macaca sinica) at polonnaruwa, sri lanka. | a seroepidemiological study of arboviruses infecting 115 wild toque macaques (macaca sinica) at polonnaruwa, sri lanka showed a high prevalence of antibodies to dengue and lumbo viruses. there was low seroprevalence of chandipura (2/115) and batai (1/115) virus antibodies, but no seropositivity to chikungunya or sindbis. there was no serological evidence of infection by japanese encephalitis (je) virus in spite of large human epidemics in the study area, indicating that toque macaques are unlike ... | 1993 | 8230174 |
