Out of 150 apparently healthy male dogs from Kerala, India examined, five revealed single worm in the scrotum. They were found protruding out from beneath the tunica vaginalis when it was incised during the castration operation. Genomic DNA isolated from these worms amplified D. repens specific 246 bp PCR products (KP050552, KP050553). Thickened and enlarged epididymis along with interductal fibrosis, congestion of veins and widening of the cavernous spaces of testes and epididymis were observed in the worm infected dogs. Semeniferous tubules were intact and showed various developmental stages of sperms. The infection resulted in less impact on spermatogenesis.The present communication forms the first report from India on the presence of D. repens in the peritoneal location, which is frequently observed in the subcutaneous locations.
在对来自印度喀拉拉邦的150只外表健康的雄性犬进行检查时,有5只在阴囊中发现了单条蠕虫。在阉割手术切开鞘膜时,发现它们从鞘膜下方突出。从这些蠕虫中分离出的基因组DNA扩增出了D. repens特异性的246 bp PCR产物(KP050552,KP050553)。在感染蠕虫的犬中,观察到附睾增厚、肿大,伴有导管间纤维化、静脉充血以及睾丸和附睾海绵体间隙增宽。生精小管完整,显示出精子的各个发育阶段。感染对精子发生的影响较小。本报告是印度关于D. repens出现在腹膜位置的首次报道,该蠕虫通常见于皮下位置。
