“…5,10,11 The prevalence of intestinal parasitic infections varies with different geographical regions. 12 The variation could be due to differences in geographical location: in Ikeh et al, 5 Nduka et al, 10 and Awolaju and Morenikeji, 11 studies were conducted in north central, south eastern, and south western Nigeria respectively, in contrast to our study which was conducted in Mid Western Nigeria.…”

Intestinal parasitic infections are associated with morbidity and mortality worldwide. Data on prevalence of intestinal parasitic infection is sparse in rural Nigeria. Against this background, this study aimed at determining the prevalence of intestinal parasitic infections within a four year period in the rural community of Okada, Edo State, Nigeria. Fecal samples obtained from 1528 patients (consisting of 740 males and 788 females) presenting with signs and symptoms of gastroenteritis at the Igbinedion University Teaching Hospital, Okada were examined for presence of ova, cyst and trophozoites of parasites using standard methods. Patient's age ranged from 6 months to 73 years. Study was conducted between 2007 and 2010. The prevalence of intestinal parasitic infections increased significantly (P=0.003) from 14.7% in 2007 to 22.5% in 2010. In the study period, gender did not affect the prevalence of intestinal parasitic infection (P>0.05). Patients within <1-10 years had significantly higher prevalence of intestinal parasitic infection. Ascaris lumbricoides was the most predominant parasitic agent, while Schistosoma japonicum was the least prevalent. With respect to parasite, males were observed to have consistently higher prevalence of Entamoeba histolytica infection. The prevalence of intestinal parasitic infection was observed to significantly increase from 2007 to 2010. Age was a risk factor for acquiring intestinal parasitic infection. Ascaris lumbricoides was the most predominant parasitic agent in all years of study. Control and prevention measures are advocated.

Background:Intestinal parasites of humans are one of the most important health problems worldwide, especially those located in tropical and subtropical areas. Objectives: The aim of this study was to determine the frequency of intestinal parasites in patients with gastrointestinal disorders, in different parts of Iran. Patients and Methods: A total of 1520 stool samples were collected from patients with gastrointestinal disorders. The stool specimens were examined by direct wet mount, formalin-ether concentration and a modified version of the Ziehl-Neelsen staining technique. Amoeba-positive samples were cultured for further differentiation of Entamoeba histolytica, E. dispar, E. moshkovskii. DNA-based methods were used to differentiate these amoebas and to detect Cryptosporidium-positive samples. Statistical analysis was carried out by SPSS ver. 16.Results: Out of the 1520 individuals studied, 153 (10.06%) were infected at least with one intestinal parasite. 781 (51.4%) of patients were male and 738 (48.6%) were female. The prevalence of protozoan parasites 148 (9.7%) was significantly higher than helminth parasites 5 (0.3%) (P < 0.001). The frequency of intestinal parasites was as follows: Blastocystis sp., 72 (4.73%); Giardia intestinalis, 35 (2.30%); Entamoeba coli 21 (1.38%); Endolimax nana 10 (0.92%); Cryptosporidium spp., 1 (0.06%); Entamoeba dispar, 1 (0.06%); Dientamoeba fragilis, 1 (0.06%); Hymenolepis nana, 3 (0.19%); Dicrocoelium dendriticum, 2 (0.13%). In five (0.32%) of the positive samples, co-infections with two parasites were found. G. intestinalis was more prevalent in male 22/35 (62.86%) than female 13/35 (37.14%) as well as in 0-9 years old group. In one sample Heterodera ova contained larva were seen. Conclusions: Blastocystis and G. intestinalis were the predominant intestinal parasites detected in patient with gastrointestinal disorders. The results indicated that the intestinal parasites, particularly helminth infections have been significantly declined in recent years.

Background: There are scant evidences between giardiasis and enterobiasis with human mal-absorption of micronutrient. Objectives: The aim of the present study was to found out the changes in the serum zinc, copper, magnesium and vitamin B12 levels in schoolchildren infected with Giardia intestinalis and Enterobius vermicularis. Patients and Methods: This case-control study was carried out among 359 children from aged 6 -12 years old at 8 suburban public schools. Three stool examinations were done using standard techniques for identification parasitic infection. Fifty E. vermicularis and 37 G. lamblia infected individuals were enrolled as study groups. Serum levels of copper, zinc, magnesium were assessed by autoanalyzer and vitamin B12 levels were measured using gamma counter. ANOVA and paired t-test analyses were used to determine the association between infections and trace elements changes. Results: The prevalence of G. intestinalis and E. vermicularis infections were 10.3% and 13.9%, respectively. The serum zinc, copper and magnesium levels showed a significant decrease in individuals infected with G. intestinalis and E. vermicularis (P < 0.05). Mean values of Giardia positive and negative groups for copper 143.65 ± 16.51 and 176.26 ± 17.6 μg/dL, zinc 62.26 ± 16.06 and 80.66 ± 23.58 μg/dL, and magnesium 1.82 ± 0.23 and 2.01 ± 0.16 mg/dL, respectively. Mean values of Enterobius positive and negative groups for copper 145.55 ± 26.84 and 176.26 ± 17.6 μg/dL, zinc 72.7 ± 17.92 and 80.66 ± 23.58 μg/dL and magnesium 1.93 ± 0.11 and 2.01 ± 0.16 mg/dL, respectively. Conclusions:The results showed that giardiasis and enterobiasis decreased serum levels of copper, zinc and magnesium. Further studies are needed to clarify the actual mechanism governing the zinc, copper, magnesium and vitamin B12 giardiasis/enterobiasis interaction.
