Serological examination of trypanosomes infestation in cattle reared in Keffi, Nasarawa State, Nigeria.

Background & objectives:

Cattle population is relatively dense in Nasarawa State (Nigeria) particularly in Keffi and its environs, where there are more Hausa/Fulani settlers whose main occupation is farming and herding. Unfortunately, the area is purportedly described as a "horde of tsetse fly species" which transmits trypanosomes that cause severe disease in humans, livestock and wildlife species. This study was targeted at examining trypanosome species prevalent among cattle breeds reared in Keffi metropolis.


A total of 110 cattle, purely based on availability were screened within five working days for trypanosomes infestation using haematocrit centrifugation technique and buffy coat technique. The breeds of cattle examined included White Fulani (64), Sokoto Gudali (26), N'dama (16) and Muturu (4); reared in Jarmai, Gauta and Keffi North districts of Keffi Local Government Area, Nasarawa State, Nigeria. Data collected were analysed using simple descriptive statistics.


It was observed that 18 (16.4%) out of 110 cattle screened were infested with 5 (4.55%) Trypanosoma con- golense and 13 (11.82%) T. vivax. The T. congolense positive cases were 4 (3.64%) in White Fulani and 1(0.91%) in Sokoto Gudali breeds whereas, T. vivax occurrence was 9 (8.18%) in White Fulani breed and 4 (3.64%) in Sokoto Gudali breed. The N'dama and Muturu breeds were absolutely not infested and no mixed infestation was recorded in any of the breeds.

Interpretation & conclusion:

Trypanosoma vivax and T. congolense are the predominant trypanosome species in the study area affecting mainly Sokoto Gudali and White Fulani breeds. Since, N'dama and Muturu breeds were observed to be trypano-tolerant; intensive breeding strategy, strain upgrading mechanisms and genetic modifications could be adopted to ensure other cattles' survival and prevent disease transmission in the area and beyond.
