Anosike JC, Oguwuike UT, Nwoke BEB, Asor JE, Ikpeama CA, Nwosu DC, Ogbusu FI: Studies on vesical schistosomiasis among rural Ezza farmers in the southwestern border of Ebonyi State, Nigeria. Ann Agric Environ Med 2006, 13, 13-19.

Abstract: 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 (22.1%) comprising 305 (23.7%) men and 161 (19.7%) women were infected with visible haematuria as the predominant presenting symptom. Ezza people associate bloody urine with sexually transmitted diseases. There were no significant differences in the prevalence rates amongst various villages and sexes (p>0.05). There was a gradual increase in the disease prevalence as the subjects’ age increases. About 78.3% of the infected persons are aged 0–20 years. Statistical analysis revealed that the prevalence, intensity and visible haematuria were significantly more (p<0.05) in subjects under the age of 20 than subjects above 20. Among the infected population, 183 (39.3%) and 283 (60.7%) were excreting 50 eggs/10 ml urine and above 50 eggs/10 ml urine respectively. Lack of visible haematuria is a more valid indicator of the absence of vesical schistosomiasis. Of the various snails collected during malacological survey, mainly B. globosus were infected. Possible control measures are discussed.
