of human and animal wastes, even by the side of<br />

streets (Aina, 2002, Unpublished B.Sc. project of<br />

Department of Geography, A.B.U. Zaria).<br />

Sample Collection<br />

120 cattle were randomly selected and<br />

ectoparasites specimen were collected from them.<br />

All parts of the body of cattle were carefully<br />

examined. Using hand gloves, the ticks were<br />

removed from the body of the host with all<br />

necessary precautions to avoid damage to the<br />

mouthparts of the ticks and skin of host. Specimens<br />

collected were put in folded white paper (each<br />

sample/ animal) with little space to allow the ticks<br />

have access to air. The specimen containers were<br />

carefully labeled to indicate: breed of cattle, site of<br />

tick location in the body of the animal and sex of<br />

the animal. The samples collected were then<br />

transported to the Veterinary Entomology<br />

Laboratory, ABU, Zaria and directly preserved in<br />

70 % alcohol before examination.<br />

Morphological identification<br />

The live ticks were placed in petri dish<br />

containing 70% alcohol using forceps and the<br />

samples were examined with low power dissecting<br />

microscope (Nikon, made in Japan) and identified<br />

by using the key of morphological characters as<br />

described by Service (1979).<br />

Statistical Analysis<br />

The data collected were tabulated according to<br />

the number of visits to the abattoir. The students ttest<br />

were used to compare the means, correlation<br />

analysis was also used to compare between types of<br />

ticks and the lesions, the sex and breed of cattle;<br />

using the SPSS version 16.<br />

Results and Discussion<br />

Presented in Tables 1, 2, 3, 4 and 5, about 120<br />

heads of cattle were sampled, out of which 66 (55<br />

%) were males and 54 (45 %) females. Among the<br />

breed in the same population, the White Fulani<br />

breed was the most frequent breed with 90 (75 %),<br />

followed by Red Bororo, 20 (16.7 %) and Sokoto<br />

Gudali 10 (8.3 %). The result showed that inguinal<br />

region was the most common predilection site for<br />

least with 5 (4.2 %).<br />

Four types of ticks were identified:<br />

Amblyomma variegatum, Boophilus decoloratus,<br />

Rhipicephalus sanguineus, and Hyalomma sp. The<br />

frequency of occurrence in the study showed that<br />

Amblyomma variegatum 27 (22. 5 %) was the<br />

commonest ticks observed in cattle in Zaria abattoir<br />

followed by Boophilus decoloratus, 21 (17. 5),<br />

Hyalomma, 8 (6.7 %) and Rhipicephalus<br />

sanguineus 4 (3.3 %). In addition, 19 animals had<br />

skin lesions similar to that described for<br />

Dermatophilos infection while 101 animals had<br />

none. Some of these lesions were associated with<br />

ticks’ infestations, while some were not (Table 4).
