Toxoplasma gondii is a zoonotic parasite that can infect all warm-blooded animals. It is responsible for considerable economic losses in some regions and farming systems. This review aims to synthesize current findings on the prevalence and risk factors associated with T. gondii infection in animal species in Algeria. It was performed according to the recommendations of the PRISMA guideline. A total of 14 papers from 1955 to 2020 were eligible to be included in this systematic review and meta-analysis study including a number of 10187 animals of which 2594 were positive cases (25.46%) (24.62-26.31%, 95%CI). Prevalence of Toxoplasma-infection was 20.04% in cattle, 22.57% in sheep, 33.61% in goats, 28.17% in horses, 30% in donkeys, 70.31% in stray cats, 14.57% in local rabbits, 30.47% in dogs and 50.70% in poultry farms. Adult animals and females were most infected. The highest prevalences were reported in stray cats and poultry. Rabbits were the least infected. This analysis showed a trend of increasing infection since 2015 (R² = 0.129, p > 0.05) which requires further studies to provide better prevention strategies.

弓形虫是一种人畜共患的寄生虫，可感染所有温血动物。它在某些地区和耕作制度中造成了巨大的经济损失。这篇综述旨在综合阿尔及利亚动物物种中与弓形虫感染相关的患病率和危险因素的最新发现。它是根据PRISMA指南的建议执行的。从1955年到2020年，总共有14篇论文符合纳入该系统评价和荟萃分析研究的条件，其中包括10187只动物，其中2594例为阳性（25.46％）（24.62-26.31％，95％CI）。弓形虫患病率-牛的感染率为20.04％，绵羊为22.57％，山羊为33.61％，马为28.17％，驴为30％，流浪猫为70.31％，本地兔子为14.57％，狗为30.47％，家禽场为50.70％ 。成年动物和雌性感染最多。据报道，流浪猫和家禽的患病率最高。兔子感染最少。该分析显示自2015年以来感染增加的趋势（R²= 0.129，p> 0.05），这需要进一步研究以提供更好的预防策略。
