...ere capable of emulating rickettsial antigens to enable sensitive detection of rickettsia exposure in humans who have seroconverted. Such anti-idiotypic aptamer antigens might also serve as rickettsial vaccines, if fully developed. The top five highest affinity R. rickettsii and top five R. typhi anti-Fab aptamers as assessed by enzyme-linked aptamer sorbent assay (ELASA) screening were sh...

...se caused by a rickettsial parasite Anaplasma marginale. This study investigated the prevalence of A. marginale in cattle on different commercial farms in subtropical conditions of Khyber Pakhtunkhwa (KP). A total of 120 cattle from different farms were randomly sampled and tested for the presence of A. marginale between May to August 2016. The study revealed that 15.0%, 20.8% and 29.1% of sampl...

...and Anaplasma platys are rickettsial pathogens that cause infections in the blood and have adverse health effects in animals, especially dogs and other canids. PCR targeting the 16S rRNA gene was performed to determine the prevalence of ehrlichiosis and anaplasmosis in 127 dogs collected from Rayong province, Thailand. To confirm the identification of these two pathogens, PCR was performed to detect the citrate synthase (gltA) gene followed by sequencing. In a...

...e obligate intracellular rickettsial vector-borne pathogens that impact on livestock farmers with major economic constraints and eventually threaten human health in cases of zoonotic species involvement. Therefore, our study aimed to identify Anaplasma spp. infection in a bovine host using both microscopy and molecular techniques. A total of 59 samples were collected from Mingaladon township, Yangon region, and the presence of infection was assessed using a Gi...

This study was focused on morphological and molecular identification of ixodid ticks, using morphological keys and an internal transcribed spacer (ITS-2) Deoxyribonucleic acid (DNA). Moreover, the presence of Babesia and Theileria species was also investigated in ticks using 18S rRNA gene. Identification of ticks collected from 384 cattle and 384 buffaloes screened reve...
