Three species of penaeid shrimp, Fenneropenaeus indicus, Penaeus monodon and P. semisulcatus, found in trawler catches off the west coast of Madagascar were infected with microsporidian parasites. The infections were evident as muscular lesions with a cottony appearance when abundant. Spore size (2.6 x 1.6 microm) and morphology (ovoid) for the parasites infecting both F. indicus and P. semisulcatus were not significantly different, suggesting that they might be the same microsporidian species. Spore size (1.4 x 1.1 microm) and morphology (sub-globose to ovoid) in P. monodon infections were significantly different from those in the other 2 shrimp species, suggesting that it was a different parasite. The presence of microsporidians in this biogeographical zone means that there is a potential risk of infections of cultured shrimp in farms situated in the vicinity. This must be assessed by increasing current knowledge of the parasites.
在马达加斯加西海岸拖网捕捞中发现的三种对虾，即印度对虾、斑节对虾和半滑舌对虾，感染了微孢子虫寄生虫。当感染严重时，可见肌肉出现棉絮状病变。感染印度对虾和半滑舌对虾的寄生虫的孢子大小（2.6×1.6微米）和形态（卵形）没有显著差异，表明它们可能是同一微孢子虫物种。斑节对虾感染中的孢子大小（1.4×1.1微米）和形态（近球形至卵形）与其他两种对虾的显著不同，表明它是一种不同的寄生虫。在这个生物地理区域存在微孢子虫意味着附近养殖场养殖的对虾有感染的潜在风险。这必须通过增加目前对寄生虫的了解来评估。
