Abstract
Toxoplasma gondii infection is recognized as one of the major causes of reproductive failure in sheep and goats. This survey was carried out in order to study the seroprevalence of Toxoplasma infection in sheep in Blida, Bouira and Medea regions from Algeria. The sample size was set at 220 animals distributed over 22 farms. Sera were assayed for T. gondii antibody detection by Modified Agglutination Test (MAT). The overall seroprevalence was 35.9% (79/220) with a herd seroprevalence of 77.3% (17/22). The prevalence was significantly higher in Medea (45.7% of 116 sheep), compared to Blida (27.7% of 83 sheep). Bouira region showed the lowest prevalence with 3 positive samples (14.3%) over 21 sheep. Logistic regression analysis revealed that the likelihood of T. gondii infection was higher in semi-extensive sheep breeding, in regions where the presence of cats is strong, and in highlands when compared with semi-intensive sheep breeding, weak presence of cat and in lowland, respectively. This study shows a high seroprevalence of Toxoplasma infection in sheep in these areas.

Abstract
Leishmaniasis is a neglected tropical parasitic vector-borne disease that has emerged or re-emerged in recent years and is a major health problem. Algeria is a country where leishmaniasis reaches high levels of endemicity. This systematic review and meta-analysis was performed to collect, compile and summarise data on the prevalence of animal leishmaniasis in Algeria. Data were collected from 2004 to 2022 during which a number of 12 papers were published from dogs, cats, hedgehogs, and jackals. A total of 4812 dogs, 388 stray cats, 24 hedgehogs and 2 Jackals were included in this analysis. The diagnosis of leishmaniasis was performed using serological or molecular tests. The overall prevalence in dogs was 21.2 % (95 %CI, 15.7-26.9 %), and in stray cats, hedgehogs and Jackal was, respectively, 25.3 % (95 %CI, 17-36.6 %), 20.8 % (95 %CI, 8.8-40.9 %) and 50 %. This study is a comprehensive epidemiological analysis of canine leishmaniasis in Algeria and will therefore be a useful tool for researchers. Further studies are needed for a better and continuous assessment of the occurrence of this zoonosis. It can also be used to propose or improve appropriate national surveillance programs for these diseases.
