We report a case of human nasal myiasis caused by flower fly larva in a 14-year-old rural girl in Central Province of Iran. Entomological studies on larva showed the larva as Eristalis tenax which is a rarely cause of nasal myiasis. This is the first reported case of E. tenax larva causing human nasal myiasis in Iran.

1. The second-stage larva of the plant parasitic nematode Heterodera rostocfaensis shows very little movement while confined to the egg; on the other hand, the larva of the closely related Meloidogyne incognita is very active 2. Using interference microscopy, it is shown that the water content of the Heterodera larva increases immediately it is liberated from the egg while that of the Meloidogy...

alter a definition of the condition of larva migrants and a description of the types of helminthes which cause this affection in man a brief account of the pathology and clinical manifestations of both visceral and coetaneous larva migrants is given. studies undertaken in iran have revealed the presence of most of 1ihe animal helminthes which cause coetaneous larva migrants of the parasites whi...

This is the first description of larva and puparium of Oplodontha rubrithorax (Macquart, 1838) from the Oriental Region. Larvae were found at a hot spring in North Thailand. The morphological features and cuticular structures of the larva are documented by drawings and SEM micrographs and the main characters are compared with the European O. viridula (Fabricius, 1775), the only described larva ...

During 1997, gross and histopathologic examinations were performed on an adult female raccoon (Procyon lotor) that was live-trapped in Corvallis, Oregon. Multifocal eosinophilic granulomas indicative of neural and visceral larva migrans were observed. However, within these granulomas, the presence of parasitic larva was seen only in the cerebrum. Morphologic characteristics indicated that the n...

an investigation was carried out during april to december 2000 to study mosquito fauna and ecology in guilan prov ince of northern iran. the mosquito larvae were collected by dipping method and larval habitat characteristics recorded ac cording to hydro-ecological features. in total, 3937 larvae of the genus culex from 92 larval breeding sites were collected. six spe cies of the genus culex; cx...

hydatid disease, caused by echinococcusgranulosus, is a common parasitic infection of the liver. disseminated intra-abdominal hydatid disease may occur with the rupture of the hydatid cyst into the peritoneal cavity, producing secondary echinococcosis. but primary hydatid cyst in the pelvis is rare. we report a case of bilateral hydatid cyst of the pelvis in a 53years old woman presented with a...

Strongyloidiasis is an infectious disease caused by the Strongyloides stercoralis larvae, which penetrate the skin, go through the lymphatic circulation, and migrate to the lungs before reaching the intestines. They mature and may cause cutaneous strongyloidiasis, known as larva currens because of the quick migratory rate of the larva. The authors describe a case in which the larvae did not fol...

Eriopis connexa (Germar) (Coleoptera: Coccinellidae) occurs in several countries of South America and its mass rearing is important for biological control programmes. This work evaluated biological aspects of E. connexa larva fed on eggs of Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) and Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) frozen for one day, fresh eggs of Dia...

we report a case of human nasal nosocomial myiasis in a 69-year-old rural man with numerous live maggots in nostrils. the patient was admitted in emergency ward due to dyspnea. after 72 hours the companion of patient discovered larva. the presence of the third instar larva indicated that the infestation was not more than three days. the collected instars were cleared, fixed and morphological st...
