Avian Filariasis in Backyard Chickens in Japan.

In May 2017, a hen in a backyard chicken flock in Japan exhibited mild clinical signs, and the bird was examined for diagnosis. Unexpectedly, many microfilariae were observed in the lung by histologic examination, although no adult worms were detected within the body. In a blood test performed in July, microfilaremia was confirmed in a few clinically normal chickens of the same flock. Molecular analysis of the nematode partial 18S ribosomal RNA gene revealed that the gene detected in the lung of the necropsied hen was positioned in the group of the family Onchocercidae in the phylogenetic tree. These data show that avian filarioids that can infect chickens inhabit Japan.

[Serpiginous calcifications in breast filariasis: A descriptor not included in the BI-RADS classification system]. / Calcificaciones serpiginosas en la filariasis mamaria: un descriptor no incluido en el sistema BI-RADS.

Filariasis is a parasitic disease with a benign course caused by nematodes. Filariasis is endemic in some tropical regions, and immigration has made it increasingly common in some centers in Spain. The death of the parasites can lead to calcifications that are visible in mammograms; these calcifications have specific characteristics and should not be confused with those arising in other diseases. However, the appearance of calcifications due to filariasis is not included in the most common systems used for the classification of calcifications on mammograms (BI-RADS), and this can lead to confusion. In this article, we discuss the need to update classification systems and warn radiologists about the appearance of these calcifications to ensure their correct diagnosis and avoid confusion with other diseases.

Ciência no século XIX: a contribuição brasileira para a descoberta do agente etiológico da filariose linfática / Science in the nineteenth century: the Brazilian contribution to the discovery of the etiologic agent of lymphatic filariasis

As contribuições de todos os povos para as artes de cura, ao longo de séculos, constituem a história da medicina universal. O estudo sobre as origens e o desenvolvimento dos conhecimentos médicos na história de pesquisas e descobertas leva à constatação da importância do papel de cientistas brasileiros natos ou por adoção. O objetivo deste trabalho foi ressaltar contribuições para a descoberta do agente etiológico da filariose bancroftiana. Destacam-se nomes como Otto Wucherer, Paterson e Silva Lima, que, nos primórdios do Brasil Império, criaram um modelo investigativo médico que, posteriormente, ficou conhecido como Escola Tropicalista Baiana.

[Lymphatic filariasis in Republic of Congo and scrotal elephantiasis]. / Filariose lymphatique en République du Congo et eléphantiasis du scrotum.

Cases of scrotal elephantiasis operated in the Brazzaville' hospital are naturally imputed to Wuchereria bancrofti, in spite of the absence of parasitological proof. This is due to the fact that data's diffused by WHO which are widely included in the literature, unfortunately present this filariasis as being endemic in the Republic of Congo. But it is impossible to identify what works are at the origin of this assertion during the 30 last years. What is certain, it is that no case of lymphatic filariasis was found at the time of the field surveys carried out on filariasis both in the Congo and in Gabon, country also presented as an endemic territory, at the end of the Seventies and during the Eighties. These works were unfortunately published in French. Since this time no publication related a fieldwork or a conclusive clinical observation has confirmed the presence of Wuchereria bancrofti in these two countries of Central Africa.
