Um inquerito sôbre a ocorrência do "Plasmodium juxtanucleare" em Bambuí (Estado de Minas Gerais)

A new pathogen spillover from domestic to wild animals: Plasmodium juxtanucleare infects free-living passerines in Brazil

“…Plasmodium juxtanucleare was described for the first time in 1941 in Brazil (Versiani and Gomes, 1941) and since then it has been reported in Asia (Bennett and Warren, 1966; Chen et al , 2015) and in many parts of the globe, including Africa (Earle et al , 1991; Poulsen et al , 2000) and other countries in the American continent, such as Mexico and Uruguay (Garnham, 1966). This parasite is widely distributed in Brazil, and prevalence varies from 4 to 100% in backyard chicken (Paraense, 1949; Krettli, 1972; Mota et al , 2000; Prezoto et al , 2001). The chronic phase of the infection is usually benign (Bennett and Warren, 1966; Silveira et al , 2009), but anaemia, prostration and clinical signs such as incoordination and paralysis due to neurological lesions are common at the acute phase of infection, with some cases evolving to death under experimental conditions (Krettli, 1972; Silveira et al , 2013).…”

Aspectos do parasitismo de Plasmodium (Novyella) juxtanucleare Versiani & Gomes, 1941 em Gallus gallus L., 1758 em criação rústica no município de Santa Bárbara do Tugúrio - MG

“…Os parasitos causadores da malária aviária foram alguns dos primeiros plasmódios estudados, sendo encontrados em todos os continentes e provavelmente em todos os países, em torno de 450 espécies de aves migratórias ou não (Garnham, 1966). No Brasil, registrou-se P/asmodium juxtanuc/eare (Versiani e Gomes, 1941 ), nos estados de Minas Gerais (Versiani e Gomes, 1941, 1943Paraense, 1949, Krettli, 1971, Rio de Janeiro (Massard, 1976(Massard, ,1979(Massard, , 1982Sou-za, 1998;Soares et ai., 1999), Espírito Santo (Massard, 1976), Pará (Serra Freire e Massard, 1976), Mato Grosso do Sul (Serra Freire e Massard, 1979) e Pernambuco (Mota, 1997).…”

A fragment of malaria history

“…In 1947 I examined in Bambuí 28 hens, 6 of which (21.4%) were infected. Two years later (Paraense 1949) I found 64 infected among 300 examined (21.3%). An infection rate of 20% was found by our colleague Antoniana Krettli (1972) 25 years later.…”

“…During my second visit to Bambuí (Paraense 1949) I extended the investigation to the adjacent forests, hunting 125 birds of 9 orders, and finding several species of Haemoproteus, besides Trypanosoma and Haemogregarina. Other species of Plasmodium were found in one woodpecker (Chrysoptilus melanochloros nattereri), four blackbirds (Gnorimopsar chopi chopi), four mockingbirds (Mimus saturninus frater), and one cowbird (Molothrus bonariensis bonariensis).…”
