is a protozoan parasite that is responsible for the major cause of congenital diseases, abortion, and stillbirth in humans and farm animals. Primary infection in pregnant goats due to leads to abortion and significant economic losses in the livestock industry. Moreover, very few studies have been performed for the identification of from aborted fetuses of goats. The study was conducted for the molecular identification of from aborted fetuses of goats in Chattogram, Bangladesh.
Twenty aborted fetuses of goats were collected from 52 farms in the study area. A nested polymerase chain reaction (PCR) assay targeting the B1 gene was performed, and a positive sample yield of 197 bp amplified DNA products consistent with .
The overall prevalence of toxoplasmosis in the aborted fetus of goats was 35%. Heart muscle, liver, brain, and placenta showed positive PCR results. The risk factors related to the does age, presence of cats in farms, and aborted fetus age were found to be statistically significant (p<0.05). Our results showed that is a major possible causal factor for abortion and reproductive failure in goats. The high prevalence of infection in aborted fetuses of goats revealed that could be imperative in causing reproductive failure in goats.
Active or congenital toxoplasmosis was shown by the presence of in fetal tissues, which is a matter of concern as this parasite has zoonotic significance and causes economic hazards to the livestock industry by causing various reproductive problems. Therefore, proper control measures and strategies are needed to reduce the rate of abortion in goats, ultimately saving the livestock industry.
[病原体名称]是一种原生动物寄生虫，是人类和家畜先天性疾病、流产及死产的主要病因。怀孕山羊因[病原体名称]初次感染会导致流产，并给畜牧业造成重大经济损失。此外，针对从山羊流产胎儿中鉴定[病原体名称]的研究极少。本研究旨在对孟加拉国吉大港市山羊流产胎儿中的[病原体名称]进行分子鉴定。
从研究区域的52个农场收集了20份山羊流产胎儿样本。进行了靶向B1基因的巢式聚合酶链反应（PCR）检测，197 bp扩增DNA产物的阳性样本产量与[病原体名称]相符。
山羊流产胎儿中弓形虫病的总体患病率为35%。心肌、肝脏、大脑和胎盘的PCR检测结果呈阳性。发现与母羊年龄、农场中猫的存在以及流产胎儿年龄相关的风险因素具有统计学意义（p<0.05）。我们的结果表明，[病原体名称]是山羊流产和生殖失败的主要可能病因。山羊流产胎儿中[病原体名称]感染的高患病率表明，[病原体名称]可能是导致山羊生殖失败的关键因素。
胎儿组织中存在[病原体名称]表明存在活动性或先天性弓形虫病，这令人担忧，因为这种寄生虫具有人畜共患病意义，并通过引发各种生殖问题给畜牧业带来经济危害。因此，需要采取适当的控制措施和策略来降低山羊流产率，最终拯救畜牧业。
