Infección pulmonar por Lophomonas sp en una paciente con leucemia mieloide aguda / Lung infection by lophomonas spp. in a female patient with acute myeloid leukemia

RESUMEN Las infecciones por protozoos son prevalentes a nivel mundial, en particular en pacientes inmunosuprimidos. Comunicamos el caso de una paciente procedente de la ciudad de Viña del Mar, Chile, portadora de leucemia mieloide aguda en quiense confirmó una infección por Lophomonas sp. en lavado bronquioalveolar. Se manejó con antibióticos, pero falleció decomplicaciones de su enfermedad de base. Existe poca literatura disponible respecto a este microorganismo. Concluimos que debe considerarse a Lophomonas sp. como posibilidad diagnóstica si se encuentran protozoos en lavados bronquioalveolares de pacientes inmunosuprimidos.

ABSTRACT Protozoic infections are prevalent worldwide, particularly in immunosuppressed patients. We reported the case of a patient from the city of Viña del Mar, Chile, a carrier of acute myeloid leukemia in whom an infection by Lophomonas sp. was confirmed by bronchoalveolar lavage. She was treated with antibiotics but died of complications of the underlying disease. There is little literature available on this microorganism. We conclude that Lophomonas sp. should be considered as a diagnostic possibility if protozoa are found in bronchoalveolar lavage of immunosuppressed patients.

Parasitic profiling of Japanese quails (Coturnix japonica) on two farms with conventional production system in the Amazon region / Perfil parasitário de codornas (Coturnix japonica) em duas granjas com sistema convencional de produção na Amazônia

The health monitoring and management systems of coturniculture can be deemed to be in a developmental phase when compared to the poultry industry. Studies regarding taxonomy and parasitic biology in quails (Coturnix japonica) has not been well conducted in Brazil. Most of the information is available from the autopsy case reports, in many ways the parasitic fauna of quails is still unknown. The aim of this study was to conduct a parasitological research in quails in order to contribute to ameliorate this situation. 31 quails, which were 12 months old, were used for the study. Their carcasses and viscera were sent to the Laboratory of Entomology and Tropical Diseases, INPA, Manaus/AM. The circulatory, nervous, respiratory, digestive and reproductive systems of these were studied separately. No blood parasites were found, however, nine species of endoparasites were registered which were distributed among the classes Cestoda, Nematoda and Protozoa. The helminths were distributed in the duodenum, jejunum, ileum, cecum and oviduct. The cecum was found to be the most parasitized organ and contained a wide range of parasites having three species of protozoa and three species of nematodes. Six morphotypes of Eutrichomastix globosus were recorded, and some morphotypes were hyperparasitized with sporangia Sphaerita sp. in the cytoplasm. A large number of parasites were recorded in this study, as well as the protozoan Blastocystis hominis was first being observed for quail.(AU)

A coturnicultura conta com um monitoramento sanitário e sistemas de manejo ainda em desenvolvimento quando comparado à avicultura industrial. Pesquisas de taxonomia e biologia parasitárias em codornas (Coturnix japonica) são pouco realizadas no Brasil, sendo a maioria das informações disponíveis referentes a relatos de caso em achados de necropsia, portanto, em muitos aspectos a fauna parasitária de codornas é ainda desconhecida. Este trabalho teve por objetivo realizar uma pesquisa parasitológica em codornas em fim de postura. Para pesquisa foram disponibilizadas 31 codornas com idades de 12 meses. As carcaças e suas vísceras foram encaminhadas ao Laboratório de Entomologia e Doenças Tropicais INPA, Manaus/AM. Foram estudados separadamente os sistemas circulatórios, nervoso, respiratório, digestivo e reprodutivo. Das 31 codornas examinadas nenhuma apresentou hemoparasitos, contudo, foram registradas nove espécies de endoparasitos distribuídas entre as classes Cestoda, Nematoda e protozoários. Os helmintos distribuíam-se pelo duodeno, jejuno, íleo, cecos e oviduto. O ceco foi o órgão mais parasitado e com maior diversidade de parasitas, sendo três espécies de protozoários e três de nematóides. Foram registrados seis morfotipos de Eutrichomastix globosus, sendo que, alguns morfótipos estavam hiperparasitados com esporângio Sphaerita sp. no citoplasma. Uma grande variedade de parasitos foi registrada nesta pesquisa, bem como, o protozoário Blastocystis hominis pela primeira vez sendo descrito para codornas.(AU)

Bronchopulmonary Infection of Lophomonas blattarum: A Case and Literature Review

Human infections with Lophomonas blattarum are rare. However, the majority of the infections occurred in China, 94.4% (136 cases) of all cases in the world. This infection is difficult to differentiate from other pulmonary infections with similar symptoms. Here we reported a case of L. blattarum infection confirmed by bronchoalveolar lavage fluid smear on the microscopic observations. The patient was a 21-year-old female college student. The previous case which occurred in Chongqing was 20 years ago. We briefly reviewed on this infection reported in the world during the recent 20 years. The epidemiological characteristics, possible diagnostic basis, and treatment of this disease is discussed in order to provide a better understanding of recognition, diagnosis, and treatment of L. blattarum infection.
