Urinary schistosomiasis is caused by the deposition of eggs by adult flukes in the blood vessels surrounding the bladder of the infected host. Schistosomiasis is ranked the second most important parasitic disease of man and undoubtedly the most important of helminth origin. This paper reports the prevalence of Schistosoma haematobium infection among pregnant women in some endemic tropical semi - urban communities of Anambra State, Nigeria, screened using Medi-Test Combi 9 and urine centrifugation methods. Laboratory analysis of urine samples collected from 172 pregnant women indicated that 41 (23.8%) had urinary schistosomiasis with Anam community having the highest prevalence of 35.1% among other communities. The overall prevalence and intensity of infection among age groups showed that the youngest age group in the study, 16-20 years had the highest prevalence. Out of 24 women within this age group, 12 (50.0%) were infected among which 8 (33.3%) had light infection while 4 (16.6%) had moderate infection. The peak mean intensity of 7.6 eggs/10ml urine was observed in age group 16-20 years while the oldest age group, 41-45 years had the lowest mean intensity of 1.0 egg/10ml urine. Haematuria and proteinuria which are diagnostic for schistosomiasis were higher within age group 16-20 years in all the communities with Anam community having the highest prevalence of 50% for both biochemicals within age group 16-20 years. The findings from this study will be useful in developing specific programme for this special group of women.
尿路血吸虫病是由成年吸虫在受感染宿主膀胱周围血管中产卵所致。血吸虫病是人类第二重要的寄生虫病,无疑也是蠕虫类起源中最重要的疾病。本文报告了在尼日利亚阿南布拉州一些热带半城市流行社区中,使用Medi - Test Combi 9和尿液离心法对孕妇进行筛查后,埃及血吸虫感染的患病率。对从172名孕妇收集的尿液样本进行实验室分析表明,41名(23.8%)患有尿路血吸虫病,其中阿南社区患病率最高,为35.1%。各年龄组的总体感染患病率和感染强度显示,研究中最年轻的年龄组,即16 - 20岁,患病率最高。在该年龄组的24名女性中,12名(50.0%)受到感染,其中8名(33.3%)为轻度感染,4名(16.6%)为中度感染。在16 - 20岁年龄组中观察到平均虫卵强度峰值为7.6个/10ml尿液,而最年长的年龄组,即41 - 45岁,平均虫卵强度最低,为1.0个/10ml尿液。所有社区中,16 - 20岁年龄组中作为血吸虫病诊断依据的血尿和蛋白尿发生率更高,阿南社区在16 - 20岁年龄组中这两种生化指标的患病率均最高,为50%。本研究结果将有助于为这一特殊女性群体制定特定方案。
