“…Currently, detection of Babesia infection in carrier animals is done by examination of blood smears with low sensitivities and time consuming (Todorovic 1975) or by serological methods with occasional interspecies cross reaction and cannot differentiate between postexposure and present infection (Morzaria et al 1992).…”
Babesia bovis and Babesia bigemina are distributed all over the world; the etiologic agents of the animal babesiosis are considered the most important tick-borne disease. The present research work was the first attempt to determine the prevalence of B. bovis and B. bigemina infection in ticks, in Egypt, by using polymerase chain reaction (PCR). Questing 5,243 hard and soft ticks were collected from different localities throughout the Giza Governorate. Furthermore, DNA from 500 different individual tick species was extracted and PCR was performed. Primers verified from the sequence of Mexico strain of both species were used. Two fragments of 275 and 175 bp of B. bovis and B. bigemina, respectively, were generated. Fragments of the pathogens were recovered with PCR and sequenced. The prevalence of B. bovis and B. bigemina in Boophilus annulatus ticks were 55% and 66%, respectively. Also, presence of 12% dual infection with B. bovis and B. bigemina was observed. Sequence analysis of PCR product of these pathogens shares a high degree of similarity in sequence compared to similar species found in GenBank.

“…Immunf/uoreszenz Test erwiesen sich 47 Tieren als positiv für B. bigemina, 34 (16,19,22,38,40). Fakat bu testlerden lFA Tın diğerlerine göre basit, kesin ve çabuk sonuç vermesi bakımından, son yıllarda en çok kullanılan test olarak seçildiği bildirilmektedir (7,14,25,38,40,41).…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
