| prevalence of tsetse fly and ruminant trypanosomosis in katsina-ala local government area, nigeria. | the prevalence of ruminant trypanosomosis and tsetse flies was investigated in katsina-ala local government area--a sleeping sickness endemic area--between the valleys of river benue, katsina-ala and donga in central nigeria. analysis of three hundred and twenty blood samples showed that among semi-nomadic animals, about one cattle (21.3%; 0.213, confidence interval c1 +/- 0.06) and two sheep (38.0%; 0.380, c1 +/- 0.10) out of five carried mature trypanosome infections. significantly lower (p < ... | 1996 | 9558969 |
| molecular survey of pathogenic trypanosomes in naturally infected nigerian cattle. | microscopy and polymerase chain reaction (pcr) were used to survey pathogenic trypanosome infection in naturally infected nigerian cattle. in 411 animals sampled, microscopy detected 15.1% positive infection of at least one of trypanosoma brucei, trypanosoma congolense or trypanosoma vivax, while pcr detected 63.7% positive infections of at least one of those species and trypanosoma evansi. pcr detected 4.4%, 48.7%, 26.0% and 0.5% respectively of t. brucei, t. congolense, t. vivax and t. evansi ... | 2013 | 23245680 |
