Giardiasis is the most common waterborne parasitic intestinal infection ofboth animals and humans worldwide, and it leads to significant morbidity and mortality in animals, particularly in young aged group like calves in the developing and developed world. It is a zoonotic infectious disease where animals are considered as sources of infection for humans through consumption of water and food contaminated with cysts of Giardia. Giardia species differ significantly in host range, with G. duodenalis having the broadest host range and greatest public health significance. Giardia duodenalis has eight different assemblages A through H. The disease Causes gastro intestinal disturbance, gall bladder colic and jaundice. Malabsorption and maldigestion mainly result from a diffuse shortening of epithelial microvillus. Giardia duodenalis (synonyms intestinalis, lamblia) is a flagellate binucleated protozoan, and it has two morphological forms: cysts and trophozoites. The life cycle of Giardia is direct, and the infective stage of the parasite, the cyst, is encysted when released into the feces and is immediately infectious. Trophozoites are pear-shaped, binucleate, multi-flagellated parasite forms and are the disease causing stage and colonize the upper small intestine, where they adhere to the epithelial surface and proliferate by binary fission. Infected animals, contaminated water and feed are main sources of infection. Age of animals, season of the year, area, housing, feeding, management practices are usually considered as risk factors for the occurrence of giardiasis. The infection can be transmitted by the fecal-oral route, or through contaminated food and water. To survive within the intestine, Giardia undergoes antigenic variation and few virulent factors have been identified to be responsible for the infection. These include ventral adhesive disc proteins and surface lectins, the four pairs of flagella which allow for movement and variant surface proteins. The clearance of Giardia from a host requires both innate and adaptive immunity effector mechanisms. The infection can be diagnosed by examining fecal specimens using different coproscopic techniques, serological tests and by molecular analysis. Restricting animals from surface water during periods of high cyst shedding may reduce watershed contamination. Health education on personal and environmental hygiene would help in reducing the occurrence of the infection. This review work tries to gather information on giardiasis of domestic animals with respect to its epidemiology, host immune responses, pathophysiology, distribution and its public health importance.

Toxoplasmosis is one of the most significant worldwide zoonotic infections caused by the protozoan parasite Toxoplasma gondii. It is a major public health and veterinary concern in terms of mortality and morbidity. The objective of this study was to estimate the seroprevalence and assess the potential risk factors of T. gondii infection among pregnant women, HIV/AIDS patients, and sheep in Bahir Dar city, North West Ethiopia. A cross-sectional study design and systematic random sampling techniques were employed. Serum samples were analyzed for anti-T. gondii antibodies using a commercially available Toxo-latex agglutination test kit. Logistic regression analysis was employed to test associations between variables. The seroprevalences of T. gondii infection in the examined pregnant women, HIV/AIDS patients, and sheep were 70.8% (95% confidence interval (CI): 65.1-73.4%), 70% (95% CI: 63.3-76.8%), and 43% (95% CI: 38.5 - 47.4%) respectively. Multivariable logistic analysis showed that T. gondii infection was significantly associated with knowing the zoonotic nature of toxoplasmosis (adjusted Odds ratio [AOR] = 0.197, 95% confidence interval [CI]: 0.107 - 0.35), eating raw meat (AOR=3.27, 95% CI: 1.89-5.65), and owning a cat (AOR=9.35, 95% CI: 4.00-21.84) in pregnant women and HIV/ AIDS patients. Hence, comprehensive health education about toxoplasmosis, particularly for pregnant women and HIV/AIDS patients, avoiding consumption of uncooked meat, and cat contact for immune-compromised women are of paramount importance.

Animals and humans have been intimate companions since antiquity. The history of animals discloses diverse episodes in human history. However, the history of animal disease via humans has been the least researched theme. Therefore, this study aimed to explore animal disease history with a special focus on Nagana in Gambella, Ethiopia. The study utilized content analysis of travelers’ accounts, archival documents, reports, and secondary sources. It revealed that nagana was endemic in the region due to the presence of dense forests, abundant game resources, and climatic factors. Nagana had direct and indirect repercussions. It caused the loss of domestic animals and productivity. It also influenced the economic, political, and cultural life of the people in Gambella. Moreover, limited prevention efforts exacerbated the repercussions of the disease.

Foot and mouth disease (FMD) is consistently ranked as the most economically important viral disease, and ranks among the top five important livestock diseases in Ethiopia. The status of FMD is barrier for the international trade of livestock and livestock products; thus, continuous epidemiological studies are necessary to develop efficient control strategies. This study determined the seroprevalence of FMD, associated risk factors for its occurrence, and FMD serotypes in the Adama and Boset districts of the East Shewa zone of Oromia Regional State, Ethiopia. A total of 305 blood samples were randomly collected from cattle and subjected to a 3ABC enzyme-linked immune-sorbent assay (ELISA) to detect antibodies against non-structural proteins of FMD virus (FMDV) and Solid-Phase Competitive ELISA for FMDV serotype identification. Evaluation of the associated risk factors was conducted using a multivariable logistic regression model. In this study, an overall seroprevalence of 28.2% (95% CI: 25.7% - 36.2%) was recorded. The risk of being FMD positive was significantly higher in exotic crossbreds [38.60%; OR= 2.23 (95% CI: 1.34 – 3.71); p<0.001] as compared to local breeds. The seroprevalence of FMD was significantly higher in large herd sizes [54.41%; OR=4.2 (95%CI: 3.05 - 15.87), P < 0.001] compared to medium and small herd sizes. Three FMD serotypes namely serotype O, A, and SAT-2 were identified. Besides, mixed serotypes O and A, serotypes O and SAT-2, serotypes A and SAT-2, and serotypes A, O, and SAT-2 were recorded. By considering the detection of multiple serotypes of the FMDV and the lack of cross-protection among the serotypes, the use of polyvalent FMD vaccine against the serotypes of the virus circulating under field conditions is highly recommended.

Tsetse flies are large blood-sucking flies of the genus Glossina, which are exclusively found in Africa. They are important vectors of Trypanosomes, which cause sleeping sickness in humans and African Animal Trypanosomosis (AAT) in livestock. Due to the lack of effective vaccines to control this disease, vector control has been an ideal strategy. There are many vector control methods developed so far. Sterile Insect Technique (SIT) is one of such method which depends on the mass production of male flies in the laboratory, sterilization, and release of these flies in the target area. The study was conducted to evaluate the effect of different feeding frequencies on the production and survival rate of Glossina fuscipes fuscipes to identify the best feeding frequency that could optimize the production and minimize the cost of production in a massrearing insectary facility at Kaliti Tsetse Fly Mass Rearing and Irradiation Centre, Addis Ababa, Ethiopia. Three experimental groups were established based on feeding frequency regimes. The first group was fed three times per week, the second four times per week, and the third group five times per week. Parameters that are routinely used for assessing colony performance such as; survival rate, fecundity, pupae per initial females (PPIF), and pupal quality were evaluated for each treatment group and statistical comparisons were made between the groups. The results revealed that feeding frequency had a crucial effect on fly production and survival. The lowest results for all parameters were obtained in flies fed three times per week and relatively the best results were obtained in the four-times-per-week feeding regime. Therefore, we recommend a further study on aspects that are not addressed in this study, such as emergency rate and progeny quality, to apply the four times per week feeding regime as it will have a positive economic impact that could enable more resources to be re-injected into the insectary compared to five or more feeding regimes which are currently in use in the study site.

A pilot questionnaire survey was carried out from December 2021 to June 2022 at animal health facilities in Hawassa city and Shashemene and Negele Arsi towns in Ethiopia. The objective of the survey was to determine what factors in the study area limited the provision of veterinary services at animal health facilities like veterinary clinics, veterinary pharmacies, and veterinary administrative offices. Government veterinary staff, clinical veterinarians, and private veterinary pharmacists were purposefully chosen based on their availability at each study area, whereas livestock owners (clients) were chosen at random at the point of service. A semi-structured questionnaire with multiple-choice and open-ended questions was administered to 100 study participants. It was discovered that the public sector was generally preferred by 74% of livestock owners and the private sector was preferred by 26%. In terms of infrastructurecoverage, the current animal health service delivery system was found to be deficient (35.7%). Drug shortages were a major problem for most public veterinary service providers (66.7%), while expensive drug prices were a problem for private veterinary service providers (34.0%). Additionally, it was determined that poor management (57.1%), a lack of funding (14.3%), a lack of commitment (28.6%), and a lack of attention to the veterinary sector (78.6%) were among the factors that hindered the provision of proper veterinary services in these areas. To carry out efficient veterinary clinical activities, the existing public veterinary institutions should be given sufficient financial resources,qualified personnel, and physical resources.

Ethnoveterinary medicine is part of indigenous knowledge that has been used for many centuries in the world, particularly in developing countries. Owing to its history and wider utility in our society, a survey on ethnoveterinary practice was undertaken between October 2018 and December 2019, to assess and document this traditional practice in the treatment of livestock ailments in the Dawuro zone. Data on the type of herbs/shrubs and other non-plant consumables or materials were gathered from purposively selected 81 informants using a semi-structured questionnaire. Focus group discussions, participant observations, and field trips were also made. Data obtained from the questionnaire survey were analyzed using descriptive statistics and quantitative ethnobotanical methods. Samples of plants claimed to have medicinal value were collected and botanically identified. The study revealed that 92 plant species belonging to 44 families were in use. The family Asteraceae was the most frequently reported species (11.4%). Herbs (31.7%) were the main source of traditional prepared medicine followed by shrubs (31.5%). The leaves (40.5%) and roots (34.5%) were more commonly utilized parts of plants while pounding (78.8%) was the major formulation. Among the non-plant materials, bear faeces, sharp hot iron or wire/knife, and common salt showed the highest utility level (100%). Azadirachta indica was the most preferred species to treat blackleg and also with the highest use value (UVs=0.36). The study revealed that the local communities of the study areas were rich in indigenous knowledge of ethnoveterinary practices. Thus, a strong protective policy is needed to safeguard the plant species; and develop regulations in the applications of ethnoveterinary knowledge. Moreover, bioactive validation of plant chemical content, along with testing for efficacy and safety would be part of indispensable technicalities for rational utility in the future.

A cross-sectional study was conducted from November 2021 to April 2022 to estimate the prevalence of bovine fasciolosis, assess the risk factors, and estimate the direct financial loss due to liver condemnation in cattle slaughtered at Yirgalem municipal abattoir. Furthermore, the comparison of the diagnostic efficiency of fecal and postmortem examination was evaluated. The study was based on both postmortem inspection of the liver for liver fluke infection and coprological examination using the sedimentation technique. Thus, a total of 400 cattle were sampled using systemic random sampling techniques and the prevalence was 27.0% (108/400) and 20.8% (83/400), by postmortem and coprological examination, respectively. The prevalence of F. hepatica, F. gigantica, mixed infections, and unidentified species were 56.5%, 19.4%, 16.7%, and 7.4%, respectively. The difference between age groups was statically significant (p<0.05). Coprological examination revealed the highest prevalence was recorded in the age group of > 7 years old (34%, adjusted odds ratio [AOR]=4.2) followed by 4-6 years old adults (26.8%, AOR=4.2) and in young cattle of <3 years old (6.7%). Prevalence by postmortem examination was 43.0% (AOR=4 0), 27.8% (AOR= 2.4), and 8.3%, for age groups > 7 years old, 4-6 years old adults and in young cattle of <3 years old, respectively. The body condition score result revealed a significant difference (p<0.05) as a greater magnitude of infections were detected in poor body condition animals (AOR=7.7) than in medium and good body condition (p<0.05). Considering the liver examination as a gold standard for diagnosis of fasciolosis, the sensitivity of the sedimentation technique was 76.8%, and the specificity of 100% with a very good agreement (kappa = 0.94) between the two methods. The total financial loss per annum due to the condemnation of infected liver was 945, 999 ETB (18,192.288 USD). Therefore, strategic control and prevention of the snail intermediate host should be implemented. Furthermore, upon diagnosis of fasciolosis, epidemiological information about the disease with suggestive clinical examination should be considered even in the absence of Fasciola eggs during coprological examinations and also other parasitological techniques such as the FLOTAC and FLUKE FINDER methods with high sensitivity and specificity should be employed.

Furthermore, the comparison of the diagnostic efficiency of fecal and postmortem examination was evaluated. The study was based on both postmortem inspection of the liver for liver fluke infection and coprological examination using the sedimentation technique. Thus, a total of 400 cattle were sampled using systemic random sampling techniques and the prevalence was 27.0% (108/400) and 20.8% (83/400), by postmortem and coprological examination, respectively. The prevalence of F. hepatica, F. gigantica, mixed infections, and unidentified species were 56.5%, 19.4%, 16.7%, and 7.4%, respectively. The difference between age groups was statically significant (p<0.05). Coprological examination revealed the highest prevalence was recorded in the age group of > 7 years old (34%, adjusted odds ratio [AOR]=4.2) followed by 4-6 years old adults (26.8%, AOR=4.2) and in young cattle of <3 years old (6.7%). Prevalence by postmortem examination was 43.0% (AOR=4 0), 27.8% (AOR= 2.4), and 8.3%, for age groups > 7 years old, 4-6 years old adults and in young cattle of <3 years old, respectively. The body condition score result revealed a significant difference (p<0.05) as a greater magnitude of infections were detected in poor body condition animals (AOR=7.7) than in medium and good body condition (p<0.05). Considering the liver examination as a gold standard for diagnosis of fasciolosis, the sensitivity of the sedimentation technique was 76.8%, and the specificity of 100% with a very good agreement (kappa = 0.94) between the two methods. The total financial loss per annum due to the condemnation of infected liver was 945, 999 ETB (18,192.288 USD). Therefore, strategic control and prevention of the snail intermediate host should be implemented. Furthermore, upon diagnosis of fasciolosis, epidemiological information about the disease with suggestive clinical examination should be considered even in the absence of Fasciola eggs during coprological examinations and also other parasitological techniques such as the FLOTAC and FLUKE FINDER methods with high sensitivity and specificity should be employed.","PeriodicalId":12019,"journal":{"name":"Ethiopian Veterinary Journal","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83273963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rabies is a zoonotic viral disease that affects humans and animals and dogs are the primary source of infection. Information on domestic dog populations is vitally important for rabies control. The present study is to assess the demography of dogs, the incidence of dog bites, and the knowledge, attitude, and practice (KAP) of the communities concerning rabies in Bishoftu town. Cross-sectional household surveys were conducted from April to June 2021 involving a questionnaire survey and collection of retrospective patient records from healthcare facilities. A total of 244 respondents were interviewed using a structured questionnaire format to determine their KAP about rabies and dog ownership. Data on the incidence of dog bites and suspected cases of rabies from November 2019 to June 2021 were retrieved from the records of four health centers in Bishoftu town. In interviewed households (HH) 51.2 % owned at least one dog with a dog: human ratio of 1:9 and 1.54 dogs/household. In the participating households, 71% of dogs had been vaccinated against rabies. Almost all, 99% of the respondents had heard of rabies and identified the mode of transmission of rabies. However, 61.8%, had a moderate level of knowledge and 59.8% had an intermediate level of attitude, and 64.3% satisfactory level of appropriate rabies prevention practices score. There was a statistically significant association between knowledge score and age, occupation, and source of information as well as attitude score with age and source of information (p<0.05). Respondents who attend higher education were more likely to have higher practice scores in the prevention of rabies (p <0.05). There were significant correlations among the participant’s knowledge, attitude, and practice (p<0.01). A total of 612 victims were registered and received the post-exposure vaccine in Bishoftu over two years (2019 to 2021). We identified critical knowledge gaps related to factors influencing rabies prevention and control. The veterinary and public health sectors should play an important role in educating and raising community awareness. Moreover, the production and use of the banned nerve tissue vaccine in the public health sector in Ethiopia need attention.

This study was designed to assess the state of cattle production and the contributions that cattle production makes to enhance the livelihoods, food security, and nutrition of refugees and the host community in the Gambella region in southwest Ethiopia. Two hundred fifty-five cattle owners were purposefully chosen for the study, and information was gathered through questionnaires, focus group discussions, and key informant interviews. The average number of animals per household (sd; +0.002 range: 1 to 490) was 32.37. The study observed a total of 8,258 cattle of which 8,146 belonged to the Nuer breed and 112 to the Felata breed. The reason for maintaining cattle varies statistically across the host community, re-settlers, and refugee communities (x2=50.358; p-value =0.000). According to the current study, 92.5% (236/255) of cattle owners used a free-grazing system, and the mean daily milk yield per cow during the dry and rainy seasons, respectively, was 1.35L and 2.09L. All respondents (100%) agree that there exist cattle diseases in the research area, and 79.6% of cattle owners employed traditional medicine to prevent and treat cattle diseases. Some of the potentials for cattle production in the study areas were cultural value, the existence of disease-tolerant breeds, the availability of manpower, and local expertise. Therefore, it is highly advised that a thorough analysis of the various agro-ecologies in the area be necessary to understand the reproductive and productive performance of cattle.
