Epidemiology of tree-hole breeding mosquitoes in the tropical rainforest of Imo State, south-east Nigeria.

The study of tree-hole breeding mosquitoes was carried out in the tropical rainforest of Imo State Nigeria (two rural areas and two forest reserves in some parts of Orlu Senatorial Zone) between May-October 2002. Using standard entomological procedures, two macrohabitats (natural tree-holes and bamboo traps) and two microhabitats (leaf axils of cocoyams/pineapples and leaf axils of plantain/banana) were sampled for various mosquito species. Mosquitoes were recovered from all the various biotypes sampled.

Cysticercosis of slaughter cattle in southeastern Nigeria.

The incidence of cysticercosis due to Taenia saginata in both local and exotic breeds of cattle slaughtered for meat in southeastern Nigeria between November 1999 and April 2002 is reported. The examination of various organs of 25,800 cattle in 10 major abattoirs of this region showed that 6750 (26.2%) were infected with Cysticercus (C.

Studies on vesical schistosomiasis among rural Ezza farmers in the southwestern border of Ebonyi State, Nigeria.

Studies on vesical schistosomiasis and its snail vectors were carried out between October 2001-May 2002 among rural Ezza farmers inhabiting the southwestern border of Ebonyi State, Nigeria. The people are predominantly farmers. Of the 2,104 urine specimens examined in 10 communities, 466 (22.

Lymphatic filariasis among the Ezza people of Ebonyi State, eastern Nigeria.

A total of 1,243 Ezza people living in 10 communities of Ebonyi State, eastern Nigeria were examined between July 2002-January 2003 for lymphatic filariasis. This is the first time a filariasis survey due to Wuchereria bancrofti has been carried out in this state. Of the 1,243 persons examined, 210 (16.

Prevalence of Mansonella perstans infections among the nomadic Fulanis of northern Nigeria.

The study was undertaken to investigate the prevalence and clinical manifestations of Mansonella perstans infection in the nomadic Fulanis of northern Nigeria. Physical examination of 755 consenting nomads for clinical manifestations of M. perstans infection was carried out between June 1996-September 2000.

Ecology of mosquitoes of Midwestern Nigeria.

Background & Objectives: The ecology and distribution of various mosquito species is important in the determination of mosquito vector abundance and associated diseases prevalence. The distribution of various mosquito genera in natural and artificial habitats and their relative species abundance was studied between August 2002 and July 2003 in three foci (Uromi, Ekpoma and Auchi) comprising the Esan and Etsako regions of Midwestern Nigeria.

Methods: Sampling was carried out by the method of Hopkins (1952) by dipping using a pipette or ladle depending on container types.

Prevalence of parasitic diseases among nomadic Fulanis of south-eastern Nigeria.

A study was carried out to determine the prevalence of parasitic infections among the nomadic Fulanis of south-eastern Nigeria between September 2003-March 2004. Urine, stool and blood specimens were collected from each of 231 subjects. Of these, 98 (42.

Epidemiological implications of preferences of breeding sites of mosquito species in Midwestern Nigeria.

The relative abundance of the aquatic stages of mosquito species distribution in two macrohabitats was studied between August 2001 and July 2002 using four different microhabitats (plastic cups, metal cans, bamboo cups and earthenware pots). The macrohabitats were subdivided into Areas of Derived/Secondary Vegetation (ADSV) and Areas of High Human Activities (AHHA). The results revealed mosquito species belonging to three genera (Anopheles, Culex and Aedes species), which are known vectors of four different human diseases (yellow fever, arboviruses in general, bancroftian filariasis, and malaria).

Control of endemic dracunculiasis in Ebonyi state, south-eastern Nigeria.

A field study was carried out in Ozibo and the Ebonyi local government area of Ebonyi state, south-eastern Nigeria to determine the effectiveness of several intervention strategies in the control of endemic dracunculiasis in that area. During the initial study prior to the application of such measures, 14,421 subjects were examined. A total of 8,688 (60.

Endemicity of vesical schistosomiasis in the Ebonyi Benue river valley, south eastern Nigeria.

The investigation on the prevalence of patent and clinically severe infections with Schistosoma haematobium was carried out amongst inhabitants of Ebonyi Benue river valley, South Eastern Nigeria between August 2000 and June 2001. The inhabitants are predominantly farmers. Of the 3296 subjects examined from 15 randomly selected villages in the valley, 776 (23.

Dracunculiasis in the north eastern border of Ebonyi State, south eastern Nigeria.

Between January and August 2000, a house-to-house survey of dracunculiasis was conducted in 15 communities along the north eastern border of Ebonyi State, south eastern Nigeria. Of the 3,777 subjects examined, 192 (5.1%) had active cases of guinea worm comprising 109 males (5.
