ABSTRACT

A case of myiasis due to Cardylobia anthropophaga (Blanchard) (Diptera: Calliphoridae), the 'Tumbu fly', is reported for the first time in Sri Lanka, in a 10 month old infant. The infection was acquired in Zimbabwe. The child had appeared 'unwell' for nearly a week before the detection of the skin lesions. The main clinical features were irritability, restlessness and the appearance of three small lumps on the scalp behind the right ear. Identification of the fly larva and the management of myiasis are discussed.

ABSTRACT

A fauna bentônica litorânea de um açude no Morro Santana Porto Alegre, Rio Grande do Sul, Brasil (30§03'45'' e 30§03'50''S; 51§08'15''W) é analisada qualitativa e quantitativamente a partir de coletas mensais, de maio de 1979 a abril de 1980, em seis pontos marginais (942 cm**/ponto). Apresenta-se, ainda, um estudo granulométrico do sedimento e alguns parâmetros físicos e químicos como dados auxiliares à caracterizaçäo do ambiente. A fauna bêntica, quantitativamente pobre (571 organismos no Outono, 431 no Inverno, 425 na Primavera e 490 no Veräo), mostrou uma boa diversidade de animais (26 táxons). Houve um domínio das larvas de Chironomidae (43% da fauna total) seguidas deÑ Pisidium spp. (22%), Gundlachia concentrica (9,5%), Oligochaeta (85%) e larvas de Tricoptera (6,3%). Os Hirudinea, Odonata e Ceratopogonidae foram constantes, mas numericamente muito reduzidos. A diversidade específica e a representatividade numérica dos organismos do zoobentos, no mesmo açude, foram inferiores em relaçäo a fauna do plêuston. Os filtradores (larvas de Chironomidae e os Pisidium) foram numericamente mais importante na cadeia alimentar, seguindo-se os herbívoros, especialmente Gundlachia concentrica, e os carnívoros (Hirudinea, náiades de Anisoptera) que representaram apenas 5% da fauna total

ABSTRACT

Mice, rats and cats were infected either orally or percutaneously with a number of early or advanced third-stage larvae (EL3 or AL3, respectively) of G. spinigerum. Sera obtained from these infected animals and 10 human gnathostomiasis cases were tested against various developmental stages of the parasite which were prepared and used while being alive (fresh) or dead (air-dried) for the circumoval and larval microprecipitation (COP and LMP) reactions. No precipitin reactions were observed in all sera tested against unembryonated eggs, embryonated eggs and first stage larvae neither air-dried nor fresh preparations. Sera were merely reactive giving various degrees of membranous or filamentous precipitates against the air-dried preparation of AL3.

ABSTRACT

Current methods for detecting and identifying filariae in mosquitoes are laborious and time consuming. With today's technology, we can reasonably expect development of rapid, sensitive and specific assays for detecting and identifying filariae in naturally infected mosquito populations. Progress in developing such assays is reviewed.

ABSTRACT

Mosquito density in Rangas where abaca is in abundance is much higher, almost twice, than that of Putiao where abaca is absent. The adult density of Aedes poecilus over Aedes ananae in the two areas combined is 3 to 4 times whereas the larval density of the former is much lower than Aedes ananae. The banana axils is a favorite breeding place for Aedes poecilus but may also utilize the abaca axils. This finding is very favorable in the transmission of bancroftian filariasis because this species of banana is planted around houses even closer to human dwelling than the abaca plants. Aedes poecilus being more anthropophylic than zoophylic can be domesticated as Culex quinquefasciatus and Aedes aegypti which again is a factor in favor of ideal transmission of the disease. The fact that bananas are planted around houses both in villages and towns, transmission of the disease could easily occur in both places, which should be borne in mind when planning a control program. The number of dissected mosquitoes is too small to be of significance in vector determination.
