| seroprevalences of brucellosis, q-fever and toxoplasmosis in slaughter livestock in trinidad. | serum samples obtained from livestock (cattle, chickens, pigs, sheep, goats and water buffaloes) slaughtered at various slaughter houses in trinidad were screened for agglutinins to three zoonosis causing pathogens. of a total of 751 sera tested, 2 (0.3%) originating from chickens were positive for brucella abortus agglutinins using the rose bengal test (rbt), but both were negative by the tube serum agglutination test (sat). thirty-six (4.8%) of 749 sera were positive for coxiella burnetii aggl ... | 1996 | 8881416 |
| seroepidemiology of toxoplasma gondii in dogs in trinidad and tobago. | a cross-sectional study was conducted to determine the seroprevalence of toxoplasma gondii agglutinins and to investigate the relationship between various risk factors and occurrence of toxoplasmosis in dogs in trinidad. of a total 250 dogs, comprising domestic, hunting and stray dogs, 80 (32.0%) were positive for t. gondii agglutinins at a titre of > or =1:32 using a latex agglutination test. stray dogs (60.5%) had statistically significantly higher (p<0.001) seroprevalence for toxoplasmosis th ... | 2003 | 12719132 |
| toxoplasma gondii and chlamydophila abortus in caprine abortions in tobago: a sero-epidemiological study. | a sero-epidemiological study was conducted on a goat farm that experienced an abortion epidemic in the 2005 breeding season in tobago. serum samples of goats (aborting and non-aborting) and cats were collected, in addition to the use of stored sera from the farm sampled in 2003 and 2004. farm records on the reproductive and mortality rates for year 2003, 2004 and 2005 were also reviewed. the sera were screened for toxoplasma gondii antibodies using the latex agglutination test (lat), chlamydophi ... | 2006 | 16629987 |
| congenital toxoplasmosis in two health institutions in trinidad. | toxoplasmosis is the most widespread zoonosis and an important human disease particularly in children where it could cause visual and neurological impairment and mental retardation. this study was conducted to determine the prevalence of toxoplasmosis, especially congenital toxoplasmosis in patients at two health institutions in trinidad a total of 504 cord blood samples of newborn babies were collected: 174 from a women's hospital and 330 from a general hospital. in order to elicit aternal and ... | 2007 | 17910149 |
| seroprevalence and risk factors of toxoplasma gondii infection among pregnant women in trinidad and tobago. | to determine the seroprevalence of toxoplasmosis and the frequency of risk factors for the disease in women attending antenatal clinics in hospitals and local health centers in trinidad and tobago. | 2008 | 18397582 |
| seroprevalence of toxoplasmosis, leptospirosis and brucellosis in sugarcane field-workers in trinidad and tobago. | sugarcane field-workers, like rice field-workers, livestock farmers and abattoir workers are known to be occupationally exposed to zoonotic agents. the study determined the seroprevalence of immunoglobulins to toxoplasma gondii (igm), leptospira spp (igm) and brucella abortus (igg) in sugarcane field-workers across weighing stations in the island of trinidad. in addition, the association of risk factors to infections by the three zoonoses was investigated. blood samples were collected from conse ... | 2010 | 20931907 |
| frequency of detection of immunoglobulins of toxoplasma gondii, leptospira spp., and brucella abortus in livestock/farm and abattoir workers in trinidad. | toxoplasma gondi, leptospira spp., and brucella abortus are all established parasitic and bacterial zoonoses that manifest themselves in several forms of human diseases. they have been associated with occupational exposures, particularly amongst workers associated with livestock farms. the primary objectives of this study were to determine the seroprevalence of t. gondii immunoglobulin m (igm) immunoglobulins (serum antibodies), leptospira igm immunoglobulins, and b. abortus igg immunoglobulins, ... | 2011 | 21728871 |
