Cattle Ticks and Tick Borne Haemoparasite Species Identification and Associated Risk Factors in Two Districts of West Arsi Zone, Ethiopia

Different tick species and tick-borne diseases of cattle are present in Ethiopia and they induce huge production loss in livestock industry by creating serious animal health problems. The present study was conducted from November 2017 to April 2018 in Arsi Negele and Asasa districts of West Arsi Zone, Oromia National Regional State, Ethiopia. A cross sectional study design and purposive sampling technique were employed to select 384 study animals so as to identify ticks species and tick-haemoparasite species and also to identify risk factors that affect the prevalence and association of tick born diseases. Tick and haemoparasite identification were carried out by using drect stereomicroscopic and direct thin blood examination. The study identified two tick genera and four tick species. The tick species encountered were Rhipicephalus decoloratus (51.6%) Ambylomma variegatum (46.1%) Ambylomma gemma (20.1%) and Rhipicephalus evertsi evertsi (1.2%). Out of all 384 cattle examined for the presence of tick-born haemoparasites 11.4% (n=44) of them were positive. From this 6.2%, 3.6 %, 1.3% and 0.8% of them were positive for Anaplasma marginale, Babesia bigemina, Babesia bovis and Anaplasma marginale, respectively. Two cattle (0.5%) were found positive for both Anaplasma marginale and Babesia bigemina. The highest prevalence of total tick born haemoparasites (57.1%) was occurred in A. Variegatum, A. gemma and R. decoloratus mixed infestations. In conclusion ticks and tick born haemoparasitic infections were common problems in the study area. Thus, awareness creation for farmers about the impacts of ticks and tick born diseases on livestock production and productivity and also applying appropriate and timely strategic tick control methods by veterinary service providers were advisable.

A Study of Prevalence of Fish Parasite in Hashenge Lake, Tigray, Ethiopia

This study was conducted at Lake Hashenge, Tigray, Ethiopia to identify parasites of fish. The objective of this study was to identify parasite of fish at Lake Hashenge, to determine the prevalence of parasitic disease of fish, to have baseline information about fish parasite in The lake Hashenge. A total of 442 different species of were sampled from the period of November 2008 to April 2009. Those include 217 of Mirror carp and 225 of Oreochromis niloticus. The fish were thoroughly examined both externally and internally for the presence of parasites. In this study the major parasites identified were CLinostomum genera 96(44.2%) in the Mirror carp and 64(28.4%) of Orechromis niloticus. Clinostomum species recovered from the feaces of the fish (gastrointestinal tract). The nematode genera of Capillaria identified from the GIT of 13(6%) Mirror carp and 14(6.2%) Oreochromis niloticus. The genera of Acanthocephalus were recovered from the GIT of 29(13.4%) of Mirror Carp and 25(11.1%) Oreochromis Niloticus. The adult of the genera Camllanus was recovered from 20(9.2%) of Mirror Carp and 27(12%) of Oreochromis Niloticus.

Twenty Five Years of Drug Discovery at the University of California Targeting Kinetoplastid Parasites

This review summarizes 25 years of screening compounds against three major kinetoplastid parasites, Trypanosoma brucei, Trypanosoma cruzi, and Leishmania spp. The work was carried out at two University of California campuses by a consortium of scientists. The history of this effort is summarized beginning with DARPA and NIAID TDRU projects. The compound collections that were screened came from both academic and industry sources.
