ABSTRACT. An epidemiological study of Babesia canis in dogs in Nigeria was performed. Four hundred blood samples collected from dogs in Nigeria were investigated using nested PCR and sequence analysis. On nested PCR screening, nine samples (2.3%) produced a band corresponding to a 698-bp fragment indicative of B. canis infection. Sequence analysis of the PCR products identified eight samples (2.0%) as B. canis rossi and the ninth (0.3%) as B. canis vogeli. This is the first report of the prevalence of B. canis rossi and B. canis vogeli in dogs in Nigeria.
ABSTRACT. An epidemiological survey of bovine Setaria collected from the abdominal cavities was performed morphologically on the cattle in Aomori and Kumamoto Prefectures, Japan, between August 2005 and July 2006. Fifty Setaria worms were collected from the cattle in Aomori Prefecture and 847 from those in Kumamoto Prefecture. Of these worms, 35 were identified as Setaria digitata, 14 as S. marshalli, and one as S. labiatopapillosa in Aomori Prefecture, while 816 were identified as S. digitata and 31 as S. marshalli in Kumamoto Prefecture. KEY WORDS: Aomori Prefecture, bovine Setaria, Kumamoto Prefecture.
ABSTRACT. The prevalence of Hepatozoon canis infections in dogs in Nigeria was surveyed using molecular methods. DNA was extracted from blood samples obtained from 400 dogs. A primer set that amplified the Babesia canis 18S rRNA gene, which has high similarity to the H. canis 18S rRNA gene, was used for the PCR. As a result, samples from 81 dogs (20.3%) produced 757 bp bands, which differed from the 698 bp band that corresponded to B. canis infection. The sequence of the PCR products of 10 samples were determined, all of which corresponded with the H. canis sequence.
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.
