“…Similar parasitic diversity was found in other African countries, with prevalence levels also expressive, as reported in Ethiopia by Fontie et al [13] with PC = 71.3%, although research conducted in that same country by Obs. : Exponents with equal lowercase letters in the same column indicate a non-significant difference at the 5% level between the dominance coefficients (DC); exponents with different letters in the same column indicate a significant difference between DC (p < 0.05).…”

Background: Intestinal parasites are among the most common pathogens found in humans. Helminths and protozoa which colonize the intestine constitute an important public health problem in the world. Considering that more than half of the world population is infected by enteroparasites, with high prevalence among the poorest, this research aimed to investigate parasitological indicators among children under fifteen years of age in the rural community of Saurimo, Angola. The research had an individualized, observational and cross-sectional design, in the year of 2012. Material and methods: 721 stool samples were examined and preserved in Merthiolate-iodine-formaldehyde solution (MIF). Laboratory tests were performed by coproscopic method. Results: 308 helminth, eggs or protozoan cysts were found, corresponding to the prevalence coefficient (PC) of 42.7%. Among them, 229 were positive for helminths (PC = 31.8%) and 118 for protozoa (PC = 16.4%). Monospecific parasitism was identified in 241 (PC = 33.4%) and polyparasitism in 67 (PC = 9.3%). Ascaris lumbricoides was the most frequent species with 158 cases, with dominance coefficient (DC) of 51.3%. Among protozoal infections, the most common species was Entamoeba coli, in 101 cases (DC = 32.8%), (DC = 5.2%). The age group between two and five years old was the class with the highest incidence, with 144 cases, dominance coefficient (DC) of 46.8%. Cases of simultaneous parasitism by two or more species occurred in 62 samples (PC = 8.6%, DC = 20.1%), and simultaneity by three species occurred in five cases (PC = 0.7%, DC = 1.6%). The results were the basis for proper counselling and intervention. Conclusions: The study revealed the need for orientation of government measures and educational partners to improve the living conditions of the community of Saurimo, Angola.

Back ground: Intestinal parasitic infections are still quite common in developing countries including Ethiopia, particularly in children. They are mostly associated with unsafe and low quality of drinking water, poor personal and environmental sanitation. Thus, the objective of this study was to assess the prevalence and determinant factors of intestinal parasites among school children. Methods: A cross sectional study was conducted in March, 2014, among 498 students selected from three governmental elementary schools in Arbaminch-town, Southern Ethiopia using stratified multistage sampling method. Structured questionnaire was used to identify environmental, socio demographic and behavioral factors. Stool specimens were collected from all study subjects and were examined for intestinal parasites using direct smear (mount examination) and Formal-ether concentration techniques. Finally, data entry and analysis was done using Epi-info and SPSS statistical soft ware respectively. A bivariate and multivariate logistic regression analysis was done. P value less than 0.05 was considered as statistically significant. Results: A total of nine parasites were detected .The overall prevalence of intestinal parasites was 27.7% (95% confidence interval (CI): (23.8-31.6%)). The predominant parasite was E.histolytica/dispar 64(12.9%) followed by A.lumboricoids 53(10.6%), H.nana 21 (4.2%) and G.lamblia 21 (4.2%). Hand washing practice before meal [AOR = 5.7; 95% CI (3.4, 9.7)], nail hygiene [AOR= 2.6; 95% CI (1.5, 4.4)], and children's mother educational level [ A OR =3.5; 95% CI (1.01, 11.4)] showed statistically significant association with high rates of intestinal parasitic infections. Conclusion and recommendations: The prevalence of intestinal parasites is high in the study area among school children .Thus, it indicates the need of interventions like health education regarding to personal hygiene and mass treatment.

“…In northwest Ethiopia where only sporadic fascioliasis had previously been described, 3.3% of children were found infected in 2013. 2 In some provinces of Vietnam, a prevalence between 2% and 11% have been reported. 3 Similarly, new endemic areas have been described in Iran and Kyrgystan.…”

is the most widely distributed trematode infection in the world. Control efforts may be hindered by the lack of diagnostic capacity especially in remote endemic areas. Polymerase chain reaction (PCR)-based methods offer high sensitivity and specificity but require expensive technology. However, the recombinase polymerase amplification (RPA) is an efficient isothermal method that eliminates the need for a thermal cycler and has a high deployment potential to resource-limited settings. We report on the characterization of RPA and PCR tests to detect infection in clinical stool samples with low egg burdens. The sensitivity of the RPA and PCR were 87% and 66%, respectively. Both tests were 100% specific showing no cross-reactivity with trematode, cestode, or nematode parasites. In addition, RPA and PCR were able to detect 47% and 26% of infections not detected by microscopy, respectively. The RPA adapted to a lateral flow platform was more sensitive than gel-based detection of the reaction products. In conclusion, the RPA is a highly sensitive and specific test to diagnose chronic infection using stool samples. The RPA lateral flow has the potential for deployment to endemic areas after further characterization.
