Tick-borne diseases (TBDs) cause significant losses among livestock and impact the livelihoods of resource-poor farming communities worldwide. In Ethiopia, detailed studies on the epidemiology of tick-borne pathogens (TBPs) in cattle using sensitive molecular detection methods are scarce. The objective of this study was to determine the prevalence and species composition of bovine TBPs of veterinary significance in local cattle populations.

An essential step in the molecular detection of tick-borne pathogens (TBPs) in blood is the extraction of DNA. When cooled storage of blood under field conditions prior to DNA extraction in a dedicated laboratory is not possible, the storage of blood on filter paper forms a promising alternative. We evaluated six DNA extraction methods from blood spotted on FTA Classic cards (FTA cards), to determine the optimal protocol for the subsequent molecular detection of TBPs by PCR and the Reverse Line Blot hybridization assay (RLB).

Article Synopsis
  • The study analyzed the genetic diversity of Moniezia tapeworms collected from domestic ruminants in Senegal and Ethiopia using mitochondrial cox1 and nuclear SSU rDNA sequences.
  • It found that Moniezia benedeni was present in cattle, while Moniezia expansa was identified in sheep and goats, with some specimens not able to be identified due to missing diagnostic features.
  • Phylogenetic analysis showed distinct genetic clades between sheep/goat and cattle tapeworms, with higher genetic divergence (up to 13% in cox1) between the two groups compared to the variations within sheep/goat specimens.

The African origin of hominins suggests that Taenia spp. in African carnivores are evolutionarily related to the human-infecting tapeworms Taenia solium, Taenia saginata and Taenia asiatica. Nevertheless, the hypothesis has not been verified through molecular phylogenetics of Taenia.

To identify the etiologic agents of cystic echinococcosis in Ethiopia, unilocular hydatid cysts were collected from 11 sheep, 16 cattle and 16 camels slaughtered in abattoirs of Aweday, Jijiga, Haramaya and Addis Ababa during June 2010 to February 2011. A PCR-based DNA sequencing of the mitochondrial cytochrome oxidase c subunit 1 gene (cox1) was conducted for 40 cysts. The majority of cysts (87.

Background: Infectious bursal disease (IBD) results in economic loss due to mortality, reduction in production efficiency and increasing the usage of antibiotics. This study was carried out to investigate the modulatory roles of dietary n-3 polyunsaturated fatty acids (PUFA) enrichment in immune response and performance of IBD challenged broiler chickens.

Methods: A total of 300 day old male broiler chicks were assigned to four dietary n-3 PUFA ascending levels as the treatment groups (T1: 0.

Background: Chicken anemia virus (CAV) is the causative agent of chicken infectious anemia (CIA). Study on the type of CAV isolates present and their genetic diversity, transmission to their progeny and level of protection afforded in the breeder farms is lacking in Malaysia. Hence, the present study was aimed to detect CAV from commercial broiler breeder farms and characterize CAV positive samples based on sequence and phylogenetic analysis of partial VP1 gene.
