Despite the existence of a national control program for cattle brucellosis since 1995, abortion remains a major concern for cattle breeders in Algeria even among officially recognized cattle Brucellosis-free herds. The objective of this study is to investigate i: the abortion rate among officially recognized cattle Brucellosis-free herds, ii: the seroprevalence of some abortive infectious agents within cattle Brucellosis-free herds, iii: evaluate the abortion risk factors associated with the seropositivity of the investigated abortive agents among brucellosis cattle-free herds.</p><p><strong>Results: </strong>The present study reveals an abortion rate at the herd and the individual level of 47, 36% (20/38) and 29, 06% (50/172) respectively. Herd seroprevalences were as follows: neosporosis (31,57%), toxoplasmosis (28,94%); chlamydiosis (Chlamidophila abortus) (15,78% ); Q fever (Coxiella burnetii) (47,36%); Bovine viral diarrhea (BVD) (60,52%) and infectious bovine rinotracheitis (IBR) (42,10%). The risk factor analysis using a multivariable logistic regression model at the herd level showed that seropositivity to neosporosis (OR = 1, 11, CI: [0,85 - 1,19]); toxoplasmosis (OR = 1,95, CI: [1,22 - 2,84]); IBR (OR = 1,78, CI: [1,59 - 2,79]); BVD (OR = 1,65, CI: [1,86 - 3,43]); Q fever (OR = 1,51, CI: [1,42 - 2,53]) is a risk factor for abortion. Additionally, our findings reveal that the presence of co-infection is also a risk factor for abortion among Algerian Brucellosis-free herds. The risk for abortion at the herd level was 1,41 times higher for double and triple-infected herds and 1,65 times higher for quintuple-infected herds compared to negative. Moreover, managerial factors, such as hygiene practices on farms, the presence of primiparous cows, and mixed breeding livestock, were identified as additional risk factors for abortion.</p><p><strong>Conclusion: </strong>Based on these results, particular attention should be given to the studied abortive agents to strengthen the prevention and control plan.

Thus, we conducted a study to assess knowledge, attitudes, and perceptions of rural dog owners living in the districts of Gaza and Inhambane provinces, south of Mozambique, on cystic echinococcosis (CE) followed by a survey on the prevalence of gastrointestinal parasites with emphasis on Taeniidae infection in dogs from the same districts. A structured questionnaire was administered to 335 dog owners to assess their knowledge, attitudes and perceptions related to the risk factors for transmission, control, and prevention of CE. Responses were analyzed with SPSS software using the Chi-square test. To determine the prevalence of endoparasites, 723 dog fecal samples were collected and processed using a flotation technique to detect helminths/protozoa eggs/cysts/oocysts and modified Ziehl Neelsen staining to detect Cryptosporidium oocysts. Samples positive for taeniids were further processed to identify them to species level using molecular techniques. 3% (10/335) of respondents of the questionnaire were aware of CE which was higher in males (2.7%; 9/335) compared to females, in respondents aged 26-45 years old (2.1%; 7/335), and in agro-pastoralists (1.8%; 6/335). An overall prevalence of 93.7% (678/723) for at least one parasite species was found. Prevalence was 7.6% (55/723) for Spirocerca spp., 50.9% (368/723) for Ancylostoma spp., 4% (29/723) for Toxocara spp., 5.4% (39/723) for Trichuris spp., 8.7% (63/723) for Sarcocystis spp., 8.4% (61/723) for Dipylidium caninum, 8.7% (63/723) for Isospora spp., 2.2% (16/723) for Giardia spp. and 1.7% (12/723) for Cryptosporidium spp. Prevalence of taeniids was 2.4% (17/723) with six isolates identified as Taenia hydatigena and two as Taenia multiceps. Results of questionnaire survey showed that the Knowledge of cystic echinococcosis in districts of southern Mozambique was limited, and we recommend the development of targeted public health campaigns to raise awareness of local communities about transmission cycles and prevention CE.
