Abstract
The present study was aimed to detect the prevalence of Wolbachia, haemoprotozoan and rickettsial pathogens in ixodid ticks of sheep and goats. A total of 2236 ticks were collected from sheep and goats in unorganized and organized farms of Tamil Nadu. In unorganized farms, among 2096 ticks, 890 ticks from sheep and 1206 ticks from goats were collected from Dharmapuri and Tiruvannamalai districts of Tamil Nadu. In organized farms, among 140 ticks, 75 ticks from sheep and 65 ticks from goats were collected from LFC- Madhavaram, PGRIAS- Kattupakkam and MSRS- Pottaneri.
Ticks were examined under the stereo zoom microscope analysing the external morphological characteristic using standard keys. In unorganized farms, H.bispinosa (488), H.intermedia (242) and R.haemaphysaloides (162) tick species were identified from sheep in two districts of Tamil Nadu and H.bispinosa (777), H.intermedia (239), H.kutchensis (69) and R.haemaphysaloides (155) tick species were identified from goats in two districts of Tamil Nadu. In organized farms, H.bispinosa (45) and R.haemaphysaloides (30) tick species were identified from sheep and H.bispinosa (50) and R.haemaphysaloides (20) tick species were identified from goats in LFC- Madhavaram, PGRIAS- Kattupakkam and MSRS- Pottaneri farms
