Detection and identification of Theileria and Babesia species in 920 apparently healthy small ruminants in eastern Turkey, as well as parasite genetic diversity, was investigated using a specifically designed reverse line blot (RLB) assay. The hypervariable V4 region of the 18S ribosomal RNA (rRNA) gene was amplified and hybridized to a membrane onto which catchall and species-specific oligonucleotide probes were covalently linked. Three Theileria and one Babesia genotype were identified. Comparison of the Theileria genotypes revealed 93.6-96.2% similarity among their 18S rRNA genes. Two Theileria shared 100% and 99.7% similarity with the previously described sequences of T. ovis and Theileria sp. OT3, respectively. A third Theileria genotype was found to be clearly different from previously described Theileria species. The genotype was provisionally designated as Theileria sp. MK. The Babesia genotype shared 100% similarity with Babesia ovis. The survey indicated a high prevalence of piroplasm infections in small ruminants (38.36%). Theileria spp. prevalence was 36.08%. Prevalence of B. ovis was 5.43%. The most abundant Theileria species identified was T. ovis (34.56%) followed by Theileia sp. MK (1.30%) and Theileria sp. OT3 (0.43%). 相似文献

Drying of leaf protein concentrate (LPC) in either a cabinet dehydrator or in a steam heated drum drier adversely affected extractability of lipids and availability of essential amino acids. Extraction of heated protein with chloroform: methanol mixture or acetone improved availability of amino acids. The amount of available essential amino acids in the freeze dried LPC was also increased by solvent extraction. 相似文献
