Parasitic infections in Cattle (a. Cattle ticks)

Endoparasites live inside the host. The may either be microparasites such as: blood protozoans (Theileria, Babesia, Trypanosomes) or macroparasites like: Helminths (Trematodes, Cestodes, Nematodes)

Ectoparasites include ticks, mites, leeches, flies etc . They live on the outer surface of the host. The most common ectoparasites are ticks which causes cattle tick fever, Theileriosis ,Babesiosis etc.

Ticks were collected  from a cow suspected of Theileriosis showing the following symptoms: fever, tick infestation, rough coat, restlessness, decreased milk production etc.  and stored in 10% Formalin  and basic fixation techniques were carried out. Based on the Anatomy, the tick was identified as Boophilus microplus in the Nymph stage (8 legs). Various parts were identified under a foldscope.

  1. Head

2.  Spiracle

3. Anus and anal groove.

5. Festoons

They are small areas separated by short grooves on the back margin of the tick. This helps to distinguish all other ticks from Ixodes ticks, which lack festoons.

6. Genital opening and groove

7. 4 legs indicating that larvae is in nymph stage

    Dear @LakshmiSundaram

    This is just an incredible post. Thanks for taking the time to share and explain different parts. Could you also share how you collected the samples; and few pictures of the surroundings.

    What is the prevalence of these on cattle’s? Do we know known bugs they can transmit in cattle?
