background: the american foulbrood disease (afb), caused by paenibacillus larvae subsp. larvae, is one of the main plagues affecting honey bee (apis mellifera l.) colonies, and it has a high negative impact on beekeepers worldwide. objectives: the aim of this research was to describe the evidence of paenibacillus larvae larvae contamination of honey bee colonies, in the east azerbaijan province...

Visceral and cutaneous larva migrans are parasitic zoonoses caused by the infection of larval nematodes Toxocara sp. and Ancylostoma sp. respectively. The objective of this study was to investigate the contamination by Toxocara sp. eggs and Ancylostoma sp. eggs and larva of soil samples collected from public parks and children's playground areas in state of Minas Gerais, Brazil, using both Baer...

The contaminated soil with mammal feces is an important factor of risk to infection with zoonotic diseases. Amongst these zoonoses are visceral larva migrans and cutaneous larva migrans caused by Toxocara spp. and Ancylostoma spp., respectively. The aim of this study was to assess the environmental contamination by Toxocara spp. eggs and hookworms (Ancylostoma spp.) in public parks and squares ...

(Received: June 6, 2013; Accepted in Revised Form: Nov. 13, 2013) Abstract: Although medical wastewaters are considered as hazardous, little attention is paid to their proper management and disposal. This study conducted on two typical educational hospitals with 300 and 220 beds capacity for parasite cysts and Ova reduction by the hospital wastewater treatment plants. Samples were collected fro...

Co-occurrence of mature larvae and male pharate pupae in benthos samples from the Loire River enabled descriptions of the larva of Homilia leucophaea. Using characters of the head capsule, the labrum, the meso- and metanotum, and the pro- and metathoracic legs, we compared H. leucophaea with larvae of six western European Athripsodes species, including a larval key to these species. The larva o...

The complexation between Cu(II) and naphthochrome green (NG) is very sensitive at pH 4.09 with the formation of complex ion [Cu(NG)2(H2O)2](2-). It can thus used for the determination of Cu(II) by the light-absorption ratio variation approach (LARVA) with a good selectivity. Both the ordinary detection procedure and continuous flow analysis (CFA) were carried out, where the latter is fit for co...

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.
