Six hundred and eleven random-source dogs (338 male, 273 female) one year of age or older, from six sections of the city of Recife, Pernambuco, were examined antemortem for circulating microfilariae Dirofilaria immitis and Dipetalonema reconditum adult heartworm (D. immitis) antigen, and examined postmortem for adult heartworms. The prevalence of heartworm infection was 2.3% (14/611), as determined by necropsy for adult worms, and 1% (6/611) had circulating microfilariae of D. immitis; thus, 57.1% of the heartworm-infected dogs had occult infections. The results of serological testing indicated that 1.3% (8/611) of the dogs were positive for adult heartworm antigen. A total of 42 (6.9%) of the dogs had microfilariae of D. reconditum; 40 of these had only D. reconditum and two additional dogs had microfilariae of both species, D. immitis and D. reconditum.
对来自伯南布哥州累西腓市六个区的611只一岁及以上的随机来源犬（338只雄性，273只雌性）进行生前循环微丝蚴、犬恶丝虫和匐行恶丝虫成虫心丝虫（犬恶丝虫）抗原检测，并在死后检查成虫心丝虫。通过尸检成虫确定的心丝虫感染率为2.3%（14/611），1%（6/611）有犬恶丝虫循环微丝蚴；因此，57.1%的心丝虫感染犬有隐性感染。血清学检测结果表明，1.3%（8/611）的犬成虫心丝虫抗原呈阳性。共有42只（6.9%）犬有匐行恶丝虫微丝蚴；其中40只只有匐行恶丝虫，另外两只犬同时有犬恶丝虫和匐行恶丝虫微丝蚴。
