Abstract

Foodborne parasites remain a concern for human health. Among marine parasites, anisakid nematodes are notable species frequently detected in marketable fish. This study aimed to estimate the prevalence of anisakid species in fish caught along the coasts of North African countries.

A systematic literature review was carried out using two electronic databases, in accordance with PRISMA guidelines. Forty studies published between 2006 and 2024 were included in the meta-analysis. Data were analyzed using the meta package in R software, employing a random-effects model.

The overall pooled prevalence of anisakid species was 32.12% (95% CI 20.53–44.91). Molecular methods identified five Anisakis species and Skrjabinisakis physeteris. Furthermore, the detection of Contracaecum quadripapillatum and Phocanema decipiens indicated the occurrence of other Anisakidae genera not previously documented in North African coastal ecosystems.

The pooled prevalence of anisakidosis was 35.48% (95% CI 23.37–48.6).while the prevalence of Anisakinae species varied depending on the year, country, fishing area, fish habitat and fish species. The highest prevalence was recorded between 2011 and 2015 (58.14%). Morocco and Libya showed the highest infection rates, whereas Algeria had the lowest (9.74%). The Atlantic coast exhibited the highest regional prevalence (53.69%). Pelagic fish showed greater infection levels (33.54%) than demersal species. Anisakinae species were reported in 44 fish species, with Trachurus trachurus being the most frequently examined (31.22%).

The widespread distribution of anisakid species in marine fish across North Africa underscores important public health concerns and highlights the necessity for ongoing monitoring and molecular characterization in the region.

北非海域鱼类中茴香类的流行和分布：系统综述和荟萃分析。

食源性寄生虫仍然是人类健康的一个关切。在海洋寄生虫中，茴香线虫是市场鱼类中常见的重要物种。本研究旨在估计沿北非国家海岸捕获的鱼类中茴香类物种的流行程度。根据PRISMA指南，使用两个电子数据库进行了系统的文献综述。2006年至2024年间发表的40项研究纳入了荟萃分析。数据分析使用R软件中的meta包，采用随机效应模型。总流行率为32.12% （95% CI: 20.53 ~ 44.91）。分子方法鉴定了5个异尖akis种和物理鳞尖akis。此外，在北非沿海生态系统中还发现了四乳头缩缩虫和脱瘤虫，这表明在该地区还存在其他未被记录的异蝇科昆虫。总患病率为35.48% （95% CI 23.37 ~ 48.6）。不同年份、不同国家、不同渔区、不同鱼类生境和不同鱼种的流行率不同。2011 - 2015年患病率最高（58.14%）。摩洛哥和利比亚的感染率最高，阿尔及利亚最低（9.74%）。大西洋沿岸地区患病率最高（53.69%）。中上层鱼类的感染率高于底栖鱼类（33.54%）。在44种鱼类中检出异蝽科，其中以沙龙（Trachurus Trachurus）检出最多（31.22%）。北非海鱼中茴香类的广泛分布突出了重要的公共卫生问题，并突出了在该区域进行持续监测和分子表征的必要性。

期刊介绍： Research in Veterinary Science is an International multi-disciplinary journal publishing original articles, reviews and short communications of a high scientific and ethical standard in all aspects of veterinary and biomedical research. The primary aim of the journal is to inform veterinary and biomedical scientists of significant advances in veterinary and related research through prompt publication and dissemination. Secondly, the journal aims to provide a general multi-disciplinary forum for discussion and debate of news and issues concerning veterinary science. Thirdly, to promote the dissemination of knowledge to a broader range of professions, globally. High quality papers on all species of animals are considered, particularly those considered to be of high scientific importance and originality, and with interdisciplinary interest. The journal encourages papers providing results that have clear implications for understanding disease pathogenesis and for the development of control measures or treatments, as well as those dealing with a comparative biomedical approach, which represents a substantial improvement to animal and human health. Studies without a robust scientific hypothesis or that are preliminary, or of weak originality, as well as negative results, are not appropriate for the journal. Furthermore, observational approaches, case studies or field reports lacking an advancement in general knowledge do not fall within the scope of the journal.
