Background: Treatment and wastewater disposal lack in Abidjan leads to wastewater discharge in the natural environment without treatment. These waters were loaded with pathogenic microorganisms that are the causes of many diseases. Objectives: This study aims to assess the parasitological quality of water from pipes of Abididjan City, studying protozoa and helminths. Methodology: 400 samples were collected in three municipalities and 19 sites. Parasites were identified using sedimentation. Results: Biological analyzes revealed 269 (67.2%) positive samples, with the presence of 19 taxa belonging to helminths (nematodes, trematodes) and protozoa group (amoeba, ciliates, flagellates). Protozoa are most common with a clear dominance of amoebas class followed by ciliates and flagellates. In 269 positives samples, Entamoeba coli (160 (59.48%)), Endolimax nana (112 (41.64%)), Giardia spp (71 (26.4%)), and Paramecium caudatum (66 (24.54%)) are the most common species. The spatial distribution showed that Yopougon commune was the most parasitized, followed by Abobo-Adjame. The most parasitized sites were CHU, SEL, and AG. At the seasonal level, the dry season was where the parasite load was highest regardless of municipality and sites. Conclusion: The presence of these parasite groups and the diversity of parasitic taxonomic indicates faecal contamination of piped water in Abidjan city. These parasites present a potential danger for these piped waters' direct and indirect uses. Therefore, it is necessary to treat this water before any use and before it flows into surface water to avoid these parasites.
Background: Topically applied antiparasitic drugs used in dogs have evolved in terms of active ingredients, but progress has also been made through the development of drugs that control both ectoparasites and enteroparasites (nematodes and cestodes). Objective: The aim of this study is to evaluate the effectiveness of Moxidectin 3.5g/ Praziquantel 10.0g and Imidacloprid 10.0g/ Moxidectin 3.5g/ Praziquantel 10.0g combinations applied topically in dogs with helminths (cestodes and nematodes) and ectoparasites, respectively. Methods: A total number of 276 dogs were analyzed. Dogs with nematodes or cestodes were treated with Moxidectin 3.5g/ Praziquantel 10.0g. All the positive cases for ectoparasites were treated with Imidacloprid 10.0g/ Moxidectin 3.5g/ Praziquantel 10.0g. Results: The effectiveness of Moxidectin/ Praziquantel was ≥99.8% from day 14 to day 35 on all the nematodes analyzed. The effectiveness of Moxidectin 3.5g/ Praziquantel 10.0g for Dipylidium caninum was significant on day 7 (75%) and reached 100% by day 14. A significant efficacy for Taenia spp. was achieved by day 7 and 100% from day 28 AT. Eighty-three dogs tested positive for 11 classes of ectoparasites. The Imidacloprid 10.0g /Moxidectin 3.5g/ Praziquantel 10.0g treatment proved to be effective in all the ectoparasites from day 7, until reaching 100% effectiveness by day 14 in the Linognathus setosus, Ctenocephalides canis, Amblyomma americanum, Ixodes spp ., Rhipicephalus sanguineus, and Dermacentor reticulatus sp. We found a positive correlation ( r = 0.7430, p = < 0.0001 ) between the pruritus scale and lesion scale. Conclusión: The use of Moxidectin 3.5g /Praziquantel 10.0g applied topically was effective against nematodes and cestodes. Imidacloprid 10.0g/ Moxidectin 3.5g/ Praziquantel 10.0g was effective against ectoparasites and pruritus.
Background: The use of malaria infection prevalence among febrile patients is a valuable epidemiological surveillance tool. In this study, a cross sectional study was conducted among febrile patients in selected government Hospitals in Ondo State for malaria prevalence. Results: Plasmodium falciparum is the only encountered malaria parasite with prevalence values of 82.72% (426/515) and 80.19% (413/515) were obtained for microscopy and RDTs respectively. The prevalence of malaria among the males (86.59%) was higher than the females (80.65%), all age groups in this study were vulnerable with highest infection rate of 89.66% among age group 11-20 years. The parasites densities ranged between 209 and 22310 parasites/μl with a mean parasitaemia of 5522.17 ± 183.30 parasites/μl. The prevalence of malaria among the febrile participants that have taken antimalarial drug before visiting the hospital is 82.94% (389/469) with the mean parasitaemia of 4615.21 ± 188.14 parasites/μl while among the participants that have taken herbs before visiting the hospital the prevalence is 85.03% (142/167) with the mean parasitaemia of 4913.81 ± 330.20 parasites/μl. Conclusion: There was high prevalence of malaria among febrile patients and this fi nding will help improve the diagnosis and treatment of other febrile (non-malaria) infections, limit antimalarial usage to only malaria parasite-based test true positives and serve as a guide to combat malaria drug resistance in the study area.
Introduction: Cutaneous Leishmaniasis (CL) is a zoonotic disease with global distribution, especially in underdeveloped countries. This parasitic disease is caused by the bite of an infected sandfly. Case Report: We report here the first case of cutaneous leishmaniasis discovered incidentally in an 11-year-old child in a private clinic. He is a primarian boy who had a wound located on his left leg. On questioning, we ascertained that the wound was not the first one and had been present for about 2 months. The cutaneous lesion was painless but itchy. The location, the crateriform appearance, and the chronic nature of the wound led us to suspect a case of cutaneous leishmaniasis. Methods: Microscopic examination of cutaneous exsudation’s smears of lesions revealed amastigote forms of leishmania, confirming our diagnostic hypothesis. The child was placed under Imidazole-based treatment associate cloxacilline. The child also received local gentamycin-based dressings. Results: The child was cured after one month. The diagnostic issues of cutaneous leishmaniasis constitute a great challenge for practitioners in endemic zone. Also, a systematic differential diagnostic should be required in the face of chronic wounds. Conclusion: The integration of the screening and management of cutaneous leishmaniasis against Buruli ulcer are eagerly waited as a future work.
Introduction: Paragonimiasis is a very uncommon zoonosis in sub-Saharan Africa. It is a trematodial disease contracted by eating fresh or undercooked crustaceans harboring a parasite of the genus Paragonimus. About fifteen species of Paragonimus are pathogenic to humans. In Africa, three species are frequently encountered: Paragonimus africanus, Paragonimus uterobilatéralis, and Paragonimus westermani. Clinically, it has similarities with pulmonary tuberculosis so that confusion is quickly made. Case Report: We report here a case of paragonimiasis discovered incidentally in a security guard man, 26 years old, originated from Côte d’Ivoire, who consulted in 2019 to the Medical Teaching Hospital of Cocody, for hemoptysis under a chronical mode. Results: After examination, the disease of paragonimiasis was diagnosed by positive direct smear. Otherwise, patient was positive to TB after a molecular test. An anti-tuberculosis cure was proposed, and a treatment with praziquantel 600 mg (2 tabs x3 / d for 4 days) allowed us to obtain biological cure without major side effects for paragonimiasis. Conclusion: The diagnostic issues of paragonimiasis constitute a great challenge for health systems already weakened by the instability due to covid-19 pandemic. The insufficient resources allocated to the health sector showing the lack of integration of the diagnostics of paragonimiasis to pulmonary tuberculosis program are crucial. The strengthening of human resources, as well as the improvement of the technical platform of reference laboratories in regions, are really needed.
