It is of most importance in sheep and endemic primarily in the tropical and subtropical regions where vectors (Culicoides species) are present. Materials and Methods: A cross-sectional study was conducted in July-November 2019 to examine the seroprevalence of BTV infection in ovine in Maji district of West Omo zone. Serum samples were examined for the presence of specific antibodies of BTV using competitive enzyme-linked immunosorbent assay (c-ELISA) test. The collected data was coded and analyzed using STATA version 13 software. Associations between sero-prevalence and its risk factors were tested in a Chi-square analysis and with a P<0.05 were considered as statistically significant. Results: The individual animal prevalence was revealed as 39.23% (153/390). Herd size prevalence was: small size herd (37.42%; 61/ 163), medium size herd (32.35%; 55/170), and large size herd (64.91%; 37/57). Species-based prevalence showed ovine (38.00%; 141/ 371) and caprine (63.15%; 12/19). Age-based prevalence revealed adult (39.26%; 150/382) and young (37.5%; 3/8). The cumulative sex prevalence for both ovine and caprine was male (37.95%; 52/137) and female (39.92%; 101/253). Conclusion: The current prevalence of BTV antibodies in the area was found to be high. Lack of application of bluetongue disease control mechanisms like vaccination for the animals is a key factors for the high prevalence of the disease in the areas besides the existence of the vectors.

The study aimed to isolate, identify, determine susceptibility and associated risk factors of salmonella specious in semi-intensive poultry farms of Kafa zone, southwest Ethiopia. A cross-sectional study was conducted on four purposively selected districts. Three farms were randomly selected per district and fecal samples were taken from a total of 302 chickens. Questionnaire was administered to farm owners and data was analyzed using STATA statistical software package. The overall prevalence of Salmonella enterica species in Kafa zone was 9.27% with Gimbo district 10.39%, Bita district 10.66%, Shishoende district 12% and Chena district 4%. Source of chickens, farm types and breed risk factors showed significant association (P < 0.05) with the disease prevalence. Having diarrhea and continuous farm systems significantly associated (P < 0.05). All isolates were 100% resistant to Oxtytetracycline and Ampicillin. Among 28 isolated Salmonella enterica species, 92.85% (n = 26) of them were showed multidrug resistance while 2 (7.14%) of them showed extensively drug resistance. Half of multidrug-resistant isolates were resistant to 5–6 antimicrobials, while 7.14% of isolates showed resistance to 7 antimicrobials. This study shows prevalence of Salmonella and its association with the breed, farm type, source of chicken and presence of diarrhea. A high antimicrobial resistance observed shows presence of concerns due to the emergence of Antimicrobial Resistance (AMR) in the poultry farms. Therefore, awareness should be created to the farmers on measures to avoid the risk factors of poultry disease and the occurrence of antimicrobials resistance in poultry farms.

Result: A total of 333 snakes were collected and 14 species were identified. The most prevalent species were Bitis arietans, Bitis arietanus somalica, Echis pyramidum, known as vipers, and Naja pallida, known as cobra. The highest number of snakes (75) was observed in the Northwest and Eastern parts of Ethiopia, mostly in cultivation and man-made farm land, wooded and moist dry savanna. In each hotspot a wide variety of species was observed, although composition was different. The highest snakebite incidence overlapped with the high snakes densities in Northwest Ethiopia. The snakebite annual average incidence at district level was very heterogeneous and ranged from < 15 cases/100,000 inhabitants (44% of the districts) to 309.2 cases/100,000 inhabitants. Conclusions: Snake diversity and distribution, linked to high incidence of snakebites in the hotspots, suggests a close interconnection between human, animal and environmental systems and could inform the need for antivenoms per geographical locality.

Result: A total of 333 snakes were collected and 14 species were identified. The most prevalent species were Bitis arietans, Bitis arietanus somalica, Echis pyramidum, known as vipers, and Naja pallida, known as cobra. The highest number of snakes (75) was observed in the Northwest and Eastern parts of Ethiopia, mostly in cultivation and man-made farm land, wooded and moist dry savanna. In each hotspot a wide variety of species was observed, although composition was different. The highest snakebite incidence overlapped with the high snakes densities in Northwest Ethiopia. The snakebite annual average incidence at district level was very heterogeneous and ranged from < 15 cases/100,000 inhabitants (44% of the districts) to 309.2 cases/100,000 inhabitants. Conclusions: Snake diversity and distribution, linked to high incidence of snakebites in the hotspots, suggests a close interconnection between human, animal and environmental systems and could inform the need for antivenoms per geographical locality.

Complexities arise due to the diverse materials contained in WEEE possessing unique characteristics; each component must be segregated and treated separately. WEEE has the metallic parts too nonmetallic components. Metallic parts of the WEEE having more value are recycled and reused. The nonmetallic components, for example, plastics, glass, rubber etc. are not received their dues. However, concerns about the steady increase in usage and disposal are numerous. Some of the problems include collection of waste in landfills and in normal environments. Aside from the above there are physical pro...
