We used Breteau Indices to - retrospectively - predict dengue transmission. The presence of one house block (on average about 50 houses) with a Breteau Index >or=4 in a neighbourhood (a block plus the surrounding blocks in a radius of 100 m) predicted transmission at the latter level with 81.8% sensitivity and 73.3% specificity during the first month of the Havana 2001 dengue outbreak. This res...

An effective control strategy for migratory pests is difficult to implement because the cause of infestation (i.e., immigration or local reproduction) is often not established. In particular, the outbreak mechanisms of the brown planthopper, Nilaparvata lugens (Stål), an insect causing massive losses in rice fields in the Yangtze River Delta in China, are frequently unclear. Field surveys of N....

BACKGROUND Rodents with a population greater than the entire population of other mammals on earth are the source of economic losses and health conflicts. One of the major health problems with the rodents is their role as reservoir hosts of zoonotic diseases. The aim of this study was to assess the infestation of commensal rodents with ectoparasites in Hamedan City, Western Iran. METHODS The s...

Poultry birds. Domestic fowl and broiler are constantly in exposure of both ecto-parasites and endoparasites. The parasitic infestation badly affect the industry in various ways, low weight birds, meat with low quality in taste and nutrients, weight reduction etc. The present study shows that broiler bird is less infected by ecto-parasites and gastrointestinal; parasites as compared to domestic...

hydatid disease is a parasitic tapeworm infestation that usually involves liver and lungs. primary retroperitoneal hydatid without liver and lung involvement is very rare. surgery is the principle method of treatment for large retroperitoneal hydatid, whenever feasible. we report a case of primary retroperitoneal hydatid cyst in 29-year-old male patient.

  Background: Head lice infestation is one of the most common parasitic infections with a long history in the world . The purpose of this study was to determine the prevalence of head lice infestation among 3-6 years old children going to nursery schools in Kashan, Iran in 2009.   Materials and Methods: This cross-sectional study was performed on 1200 children having the age range ...

Scabies and head lice infestation are two common parasitic infestations seen in children. Scabies in children can present with diffuse skin lesions and characteristic intraepidermal tunnels known as burrows. The causative mites of scabies live and move inside these tunnels. Intense pruritus is common with scabies. Head louse infestation presents with scalp pruritus, the presence of live lice, a...

| Parasitic zoonoses are considered as serious threat in a developing country like India, despite improvements achieved in the status of education and awareness of the people. This review provides an elaborate account of present status of emerging/re-emerging parasitic zoonoses in the country. Various important parasitic zoonoses viz., angiostrongylosis, cryptosporidiosis, cysticercosis, dirofi...

The aim of the present study was to determine antioxidant defence mechanisms in the rat and Hymenolepis diminuta after long-term infestation. We determined levels of oxidative stress markers, and activity of antioxidant enzymes in the rat small intestine and in particular parts of H. diminuta. Observed changes in antioxidant enzymes activity in H. diminuta and the rat intestine indicate the def...
