Snappers from the southern Gulf of Mexico (SGM) and Mexican Caribbean (CAR) were examined for parasitic nematodes to determine their richness, composition, and infection parameters (prevalence and mean intensity). From February 2016 to March 2018, 431 individuals of 8 snapper species were collected in 6 localities. In all, these fishes were parasitized by 2,275 individual nematodes belonging to 13 taxa: sp. was found in 7 of 8 host species and showed the highest prevalence (23%), while the rest had lower values (<10%). (Linnaeus) harbored the highest species richness (10 species), followed by (Walbaum) (8 species). Most localities were similar in terms of species richness but differed in the specific composition. Eight nematode taxa represent new host records for the family Lutjanidae (Gill), thus increasing to 22 the nematode taxa in the SGM and CAR. There is a potential risk to public health due to the presence of nematodes with zoonotic potential (as sp.) and the habit in the region of eating raw fish (cebiche).
对来自墨西哥湾南部（SGM）和墨西哥加勒比地区（CAR）的笛鲷进行了寄生线虫检查，以确定其丰富度、组成和感染参数（患病率和平均强度）。2016年2月至2018年3月，在6个地点收集了8种笛鲷的431个个体。这些鱼总共被2275条属于13个类群的线虫寄生：在8种宿主鱼类中的7种中发现了sp.，其患病率最高（23%），而其余的患病率较低（<10%）。(Linnaeus)的物种丰富度最高（10种），其次是(Walbaum)（8种）。大多数地点在物种丰富度方面相似，但在具体组成上有所不同。8个线虫类群代表了笛鲷科（Gill）的新宿主记录，因此SGM和CAR中的线虫类群增加到了22个。由于存在具有人畜共患病潜力的线虫（如sp.）以及该地区食用生鱼（ceviche）的习惯，对公众健康存在潜在风险。
