ABSTRACT

The frequency of eggs and cysts of intestinal parasites in domiciled dogs that lived in the city of Maringá, Brazil, was studied. From November 2006 to November 2007, stools of 81 dogs were examined, of which 44.4% were positive for some kind of enteric parasite. The most frequent was Ancylostoma spp. with 18.5% (15/81) followed by Giardia lamblia with 11.1% (9/81). There was association of parasites in 11.0% of the samples, being the most frequent Ancylostoma spp. and Trichuris vulpis (6.2%) (5/81). There were sources of contamination where the animals lived which were responsible for maintaining the parasite in the environment.

ABSTRACT

The present study was undertaken after the detection of one case of cutaneous leishmaniasis with presumed infection in one of the three remaining wooded areas in the urban area of the city of Maringá, Southern Brazil; also in view of the lack of knowledge about sand flies and their behavior. From June to September, 1995, sand flies were caught with Falcão traps during the night in the remaining wooded areas (Parque do Ingá, Bosque Dois and Horto Florestal). A total of 2,907 sand flies were caught in Parque do Ingá; 1,723 of them were aught in forest traps and 1,184 in wild animal shelter traps at the zoo. The results show that Lutzomyia whitmani is better adapted to the three areas under study and that it frequently occurs in wild animal shelters within the urban perimeter of Maringá.


Um caso de leishmaniose tegumentar com provável infecção em uma das áreas de matas remanescentes no perímetro urbano de Maringá, Paraná, Brasil, o desconhecimento da fauna e do comportamento de flebotomíneos nestas matas despertaram o interesse desta investigação. Os flebotomíneos foram coletados com armadilhas de Falcão instaladas em matas remanescentes do Parque do Ingá, Bosque Dois e Horto Florestal, de junho a setembro de 1995, no período noturno. Nestas áreas coletaram-se 3.532 flebotomíneos, prevalecendo Lutzomyia (Nyssomyia) whitmani (Antunes & Coutinho, 1939) com 3.395 (96,1%) exemplares. No Parque do Ingá, onde as coletas também foram feitas em abrigos de animais silvestres, mantidos em zoológico, foram coletados 2.907 flebotomíneos, dos quais 1.723 nestes abrigos. Os resultados mostram melhor adaptação de Lutzomyia whitmani nas matas remanescentes no perímetro urbano de Maringá e sua freqüência nos abrigos dos animais silvestres mantidos em cativeiro.

ABSTRACT

Em localidades da zona rural de cinco municípios da região noroeste do Paraná adultos e ninfas de Triatoma sordida foram capturados em 21 (41,2%) de 51 unidades domiciliares pesquisadas. Foram capturados 154 exemplares de T. sordida e 2 Panstrongylus megistus. De 135 exemplares examinados 58 (43,0%) apresentavam o Trypanosoma tipo cruzi. Constatou-se também a infecção em 57,1% (4/7) dos gambás (Didelphis sp) examinados. O peridomicílio apresentou-se mais infestado que o intradomicílio, sendo a casa de madeira abandonada a construção mais freqüente (34,7% do total investigado) e com maior taxa de infestação (53,9%). Os dados mostram um elevado índice de infestação da zona rural por espécies secundárias de triatomíneos com altas taxas de infecção por flagelados do tipo T. cruzi, em uma área endêmica para a doença de Chagas já em fase de vigilância epidemiológica.


In the rural area of five municipalities of the Northeast of the State of Paraná, Brazil, 154 adults or nymphs of Triatoma sordida and 2 Panstrongylus megistus were captured in 21 (41.2%) of 51 dwellings at the peridomestic sites. Trypanosoma cruzi-like organisms were found in 58 out of the 135 (43.0%) triatomids. Moreover, it was also found in the blood of 4/7 opossum (Didelphis sp). The triatomine infestation was more prevalent in the peridomicile than inside house. The forsaken wooden house presented the highest level of infestation (53.8%). Although the rural area of the Northeast of the State of Paraná is considered under epidemiologic surveillance it still presents a high level of peridomestic infestation by triatomids highly infected with T. cruzi-like organisms.
