Soil transmitted helmeinthiasis among apparently healthy children in Kano municipality

G U Ihesiulor, M A Emokpae, S I Adeeke, A B Samaila

 

Abstract

The prevalence of soil transmitted helminth infections in apparently healthy children of mean age 12.2 years drawn randomly from one school in each of the four local government areas of Kano, northern Nigeria were evaluated. Stool sample from 570 children were analyzed using formol ether concentration technique. 130(22.8%) of the subject were infected by soil transmitted helminthes (STH). The overall prevalence by species were Ascaris Lumbricoides (7.9%), Hookworm (5.3%) and trichuris trichiura (3.5%) respectively. 35(6.1%) of the subjects were infected with two or more soil
transmitted helminthes. The prevalence in males (24.2%) was generally higher than that of females (22%), Hookworm infection was high(45.5%) in the 15-20 years old age group, while Ascaris Lumbricoides infection was high (100%) in the 6-10 years old age group. The mean number of eggs per gramme (epg) of faeces was moderate. The study shows that subjects had high intensity of infections for Ascaris Lumbricoidesas hook worm, trichuris
trichiura as epg of faeces counted were high in them compared to what was obtained for mixed infections. It also reveals a moderately high prevalence across board for all soil transmitted helminth (STH) in Ungogo local government

Prevalence Of Malaria Parasitaemia In Pregnant Women Attending Antenatal Clinic At Jos University Teaching Hospital, Nigeria

EI Ikeh, SN Akudo, VE Uguru

 

Abstract

The prevalence of malaria parasitaemia in 200 pregnant women attending the antenatal clinic (ANC) of Jos University Teaching Hospital (JUTH) between April and June 2003 was determined. Geimsa-stained thick and thin blood films were examined microscopically for malaria parasites; the parasite densities were determined on the thick films. Eighteen (9%) of the women were positive for malaria parasites and only Plasmodium falciparum was encountered in the study. Pregnant women in the 15-20 year age group recorded the highest prevalence of 16%, closely followed by the age group 21-25 years with 15.2%. The 26-30, 31-35, 36-40 and 41-50 year age groups recorded 6.7%, 4.5%, 4.1% and 0% prevalence rates respectively. Women in their first trimester recorded 13.3% as against 10.2% and 3.8% for the second and third trimester respectively. The primigravidae had a prevalence of 12.9% as against 7.2% for multigravidae. Most of the women with malaria parasitaemia (89%) had parasite densities of less than 1000/µL of blood. The low prevalence of malaria parasitaemia in the ANC women is attributed to the regular prophylactic malaria therapy and the impacts of the health talks normally given to pregnant women during routine antenatal visits

Prevalence of measles neutralizing antibody in children under 15 years in Southwestern Nigeria

Abstract

The immune status of children under 15 years in the Southwestern region of Nigeria against measles virus was determined using the neutralization test with a view to assessing the herd immunity to the virus in these communities. A total of 256 serum samples collected from children were tested by the beta method of neutralization. Forty (15.6%) of these samples were found to be positive at a titre of 1:256, 35 (13.7%) at 1:128, 36(14.1%) at 1:64, 37(14.5%) at 1:32, 38 (14.8%) at 1:16, 27 (10.5%) at 1:8 and 16 (6.3%) at 1:4. Twenty-seven (10.5%) of the 256 samples had no detectable antibody to the measles virus. There was no significant relationship between the antibody titre to measles virus and the gender of the children (p > 0.05). Also, there was no significant difference using Chi square analysis between the neutralizing antibody titres and the age of the children (p > 0.05). All the children whose samples were tested were vaccinated against measles as attested to by their parents. However, the vaccination does not seem to protect all the children, for some of them had no detectable neutralizing antibody while some had low neutralizing antibody titre. In Nigeria, where only a single dose of measles vaccine is given at 9 month, measles may remain a serious threat to the children population with its attendant high morbidity and mortality.
