Abstract: Hydatidosis is a parasitic zoonosis caused by the larval stage of Echinococcus granulosus, posing significant public health and economic concerns in camels. A cross-sectional study was conducted from November 2018 to April 2019 to determine the prevalence of camel hydatidosis and its associated risk factors in camels slaughtered at Akaki Municipal Abattoir, Addis Ababa, Ethiopia. A total of 364 camels were randomly selected and subjected to ante-mortem and post-mortem examination. Sex, age, body condition, and origin were recorded before thorough inspection of the lungs, liver, spleen, heart, and other organs for hydatid cysts. The overall prevalence of hydatidosis was 53.6% (195/364). Females (64.5%) and older camels (>10 years; 57.7%) showed significantly higher infection rates. Camels with medium body condition had a higher prevalence (59.4%) than those in good condition. Statistically significant associations (p = 0.00) were found between hydatidosis and sex, age, and body condition, while origin showed no significant association (p > 0.05). Among 239 infected organs, the lungs were the most frequently affected (60.7%), followed by the liver (34.4%), spleen (3.7%), and heart (1.2%). Of 736 collected cysts, 494 were found in the lungs and 222 in the liver, with 157 (21.3%) fertile, 545 (74.1%) sterile, and 122 (16.6%) calcified cysts. The high prevalence of hydatidosis highlights a lack of awareness in the camel-producing areas. Therefore, public education and targeted control strategies are recommended to reduce the burden of the disease.

Abstract: This study was carried out in Western Sudan (Kordofan State) with the objective of investigating the causes and degree of infestation of sheep raised on rangelands with ball-shaped bodies (Phytobezoars). Indigenous knowledge among sheep producers on the disorder was also investigated. The data were collected via a questionnaire at six sites. Range inventory, herbarium collection and identification of plant species, diagnosis of animals for ball-shaped bodies by palpation and calculation of % incidence were carried out among herds brought to a central livestock market. Feeding trials were conducted to examine the incidence of sheep with ball-shaped bodies upon ingestion of Merrimia emarginata at four stages of growth (before flowering, at flowering, plants with immature pods and at late-maturity stages) and at four levels of feeding in the late mature stage (15, 30, 45%). The physical properties of the balls removed from sheep were studied. The occurrence of incidents as reported by 92.5% of the respondents showed the capability of diagnosing the balls. Sheep arriving at the central market showed incidences that ranged from 0 or 1% of some areas to 56.67% for others. Feeding trials indicated that 2 sheep fed on Merrimia emarginata at seed formation and late maturity stages developed 3 balls.
