“…However, some of the discrepancy between the reported results could be due to (1) the small sample size of animals, which may impair the representativity and objectivity of data; (2) the wide geographic area concerned or covered; (3) management practices (traditional, semi-intensive, and extensive); and (4) the serological methods used for detecting the infection. In this study, and in another recently published paper [25], the ELISA technique was used, whereas the results reported earlier in Algeria were obtained through an indirect immunofluorescence test (IFAT) [19] and microscopic agglutination test (MAT) [23]. This difference may be due to the sensitivity and specificity of the different serological methods applied [6,12].…”

A cross-sectional study aimed at assessing the seroprevalence and identifying the risk factors for Toxoplasma gondii infection in cattle, sheep, and goats in eight provinces located in two main Algerian agro-ecological zones was carried out from October 2015 to March 2018. Blood sera from 4074 animals of both sexes were tested for the presence of anti-T. gondii IgG antibodies, using the indirect, enzyme-linked, immunosorbent assay technique (ELISA). Moreover, to identify the potential risk factors of T. gondii infection, a survey through a breeders’ questionnaires was conducted. Nearly one-fourth of the total number of animals tested (1024/4074)—i.e., 25.1%--were seropositive. The seroprevalence in cattle, sheep, and goats was 28.7%, 25.6%, and 11.9%, respectively. The area, sex, age, and herd size were identified as risk factors for T. gondii infection. Higher seropositivity rates were recorded in cows and goats (odds ratio (OR) = 1.63 and 6.4), in old animals (cattle, OR = 2.1; sheep, OR = 1.9; and goat, OR = 3.9), and in small size herds (cattle, OR = 2.5; sheep, OR = 1.9; goat, OR = 2.2). In conclusion, there is widespread T. gondii infection in cattle, sheep, and goats in these two strategic agricultural areas. The identification of the risk factors determines the type of measures and strategies to be undertaken to reduce, control, and prevent T. gondii infection in domestic animals, and thereby reduce human infection.

“…The main risk factors associated with toxoplasma infection were age, sex, region, season management system (herd size, presence of goats in sheep flocks) (Dechicha et al 2015 ; Dahmani et al 2018 ; Benlakehal et al 2019 ; Mohamed-Cherif et al 2019 ; Ait Issaad et al 2020 ), and reproductive disorders (abortion stage, and flocks with a history of abortion) (Benlakehal et al 2019 ; Dahmane et al 2020 ; Ait Issaad et al 2020 ).…”
