Theileria mutans in Nigeria

Area of Science:

• Veterinary Parasitology
• Immunology
• Molecular Biology

Background:

• Theileria species are tick-borne protozoan parasites affecting cattle globally.
• Accurate identification of Theileria species is crucial for disease control and management in livestock.
• Previous research on Theileria in Nigeria indicated a limited understanding of circulating species.

Purpose of the Study:

• To identify and characterize two Theileria strains isolated from cattle in northern Nigeria.
• To determine the relationship of these strains to known Theileria species.
• To contribute to the understanding of Theileria diversity in Nigerian cattle.

Main Methods:

• Indirect immunofluorescent antibody test (IIFAT) was employed for serological comparison.
• Tick transmission experiments using Amblyomma variegatum were conducted.
• Histopathological examination for macroschizonts in infected cattle was performed.

Main Results:

• Two Nigerian Theileria strains showed identical reactivity to Theileria mutans in IIFAT.
• One strain was successfully transmitted by Amblyomma variegatum.
• Large macroschizonts, characteristic of T. mutans, were observed in experimentally infected cattle.

Conclusions:

• The identified Nigerian Theileria strains are consistent with Theileria mutans.
• Evidence supports the presence of Theileria mutans and Theileria velifera as the primary bovine Theileria species in Nigeria.
• Further research is warranted to fully elucidate Theileria distribution and impact in Nigeria.
