Survey on infestation to external parasites and their roles in of in transmission of protozoan disease in goat in Maku Region

The present study aims to determine the rate of infestation to external parasites, determine the fauna (genus and species) and also investigation their role in transmission of protozoan infections in goat in maku region. This survey was conducted from March 2010 (Farvardin 1389) to April 2011 (Esfand 1389). The data was analyzed by SPSS software (Ver. 16) .The results revealed that 137 goats (33.5%) were infested by hard ticks. There weren`t any infestation by other external parasites (mite, lice, flea, myias). The whole detected ticks were 435 and each goat had an average of 1.08 ticks. The identified hard ticks on goats in respect to their prevalence were Rhipicephalus bursa (68.50%),Hyaloma anatolicum.anatolicum (16.32%), Rhipicephalus sanguineus (9.46%), Haemaphysalis punctata(3.21%) and Dermacentor marginatus( 2.52%). Distribution of ticks over different parts of the body surface was as follows: groin and breasts (50.80%), head and neck (25.05%), subscapula (13.10%) and genital organs and under tail (11.03%). Out of 137 positive samples 103 goats (25.75%) were infected with Babesia, out of which 87 goats (84.46%), 12 goats (11.65%) and 5 goats (3.89%) infected with B. ovis, B. mutasi and mixed infection with B. ovis and B. mutasi, respectively. There wasn`t any infection with Theileria and Anaplasma. The results indicated that infections with Rhipicephalus bursa was the highest in goats in Maku region, and among protozoan infections, B. ovis infection was the highest one , that is the frequency of Rhipicephalus bursa in comparison to other kinds of detected ticks among positive samples of Babesia was high and is meaningful (p
