These samples were collected from patients according to age, residency during the period from ( the first of November 2021 to the end of January 2022). All samples undergo for a direct microscopic examination, The results revealed that 100(73.18%)were positive samples with Entamoeba spp. The results of microscopic examination recorded high infection rate in age group in (4-10)years83.33%. In contrast, recorded high prevalence in rural areas 76.31% than urban areas 73.68% . Showed the method nested multiplex polymerase chain reaction by using 18s rRNA small subunit gene, the first round of PCR showed the infection rate by Entamoeba spp 87(65.41%) out of 120 stool samples .The second round of nested multiplex PCR for these positive samples by using two specific primers revealed mix infection of Entamoeba dispar & Entamoeba moshkovskii with Entamoeba histolytica 5(6.25%), 2(2.5%) respectively, with significant difference at P<0.05.

INTRODUCTION: In Malaysia, there are little up-to-date data on the prevalence of Ent amoeba spp. and most of the previous studies were carried out using the conventional insensitive method of stool microscopic examinations. MATERIALS AND METHODS: A cross-sectional study was conducted from September 2018 to Mac 2019 in the three villages of Orang Asli communities at Slim River, Perak using the molecular assay. Risk factors associated with Ent amoeba spp. infection was assessed by analysing questionnaire responses obtained from the study participants. RESULTS: From the 55 stool samples collected, molecular prevalence revealed 7.3% and 9.1% E. histolytica and E. dispar infection respectively. Infection was due to indiscriminate defecation and not washing hands after playing with soil or gardening, as well as associated with gastrointestinal symptoms. CONCLUSION: This study showed that there is still an ongoing transmission of Ent amoeba spp. among the studied population, thus warrants the implementation of specific prevention and control strategies of this infection in Malaysia.

Background Intestinal protozoa infections are among the public health concern in children and can lead to considerable morbidities such as growth retardation, anemia, nutrition deficiency, physical weakness and mental health problems. In Tanzania, there is a paucity of data on intestinal protozoa infections among preschool aged children (PSAC). Broad objective This study aimed to determine the prevalence of intestinal protozoa infections among PSAC and associated risk factors in Mkuranga district, Tanzania. Methodology A community based cross-sectional study was conducted between April and June 2019 to determine the prevalence of intestinal protozoa. Stool samples were collected from PSAC and processed using formal-ether concentration method. Risk factors were identified using questionnaire and checklist. Data were entered and analysed by using Statistical Package for the Social Sciences software version 20. Univariate and multivariate logistic regressions were performed to determine association between prevalence of intestinal protozoa and socio-economic, water source, hygiene and sanitation variables. Results A total of 20 (3.8%) children were infected with intestinal protozoa (Entamoeba coli or Giardia lamblia). We found the increased risk of intestinal protozoa infections with increased age of children (AOR = 1.07, p = 0.045). Also, we observed a reduced odds of intestinal protozoa infections among PSAC living in low populated households (AOR 1-5/11+ = 0.14, p = 0.016 and AOR 6-10/11+= 0.10, p = 0.008), using non-spring water (AOR protected well/spring = 0.011, p = 0.023), (AOR bore hole/spring/spring = 0.008, p = 0.006), (AOR tap away of home/spring = 0.013, p = 0.014) and (AOR tape at home/spring = 0.006, p = 0.011)) and raised by young and middle-aged parents/guardian (AOR young/older = 0.20, p = 0.042 and AOR middle-aged/older = 0.18, p = 0.047). Conclusion There was a low prevalence of intestinal protozoa infection among PSAC in the two communities studied. Despite low prevalence of intestinal protozoa, the transmission is present hence the need to initiate control measures. Health education should be provided to parents/guardians on protecting water sources, treatment of drinking water and supervision of latrine usage by PSAC and introduction of hand washing facilities are crucial.

Intestinal parasitic diseases remain an epidemiology a real problem in Chad, but little research has been done in this area. The purpose of the study is to determine the status of intestinal parasites infection among students in a health professional training institution and to assess their level of perception of this health problem. This prospective and descriptive study took place between June and July 2018. A total of 107 stool samples were collected from students in a health professional training institution in the city of N’Djamena. Direct examination and formalin-ether concentration methods were used to search for parasites. The results showed that the overall prevalence of intestinal parasites among the students was 64.5%. The parasite species identified were Entamoeba histolytica, Giardia lamblia, Ascaris lumbricoides, Taenia solium and Strongyloides stercoralis with respective percentages: 46.73, 13.08, 13.08, 1.87, and 0.93%. The rates of infestation according to the ethological factors were: - cooking water: 46.51 and 75.80% respectively for the national water company (SNE) and drilled water; feeding mode: 60 and 64.70% for respectively individual and collective; washing hands with soap before meals: 78.57 and 62.37% for respectively no and yes. To fight the diseases caused by parasitosis should involve a strategy on sanitation and health education.The species of parasites identified indicate that the fight against diseases caused by the above parasitosis should involve a strategy on sanitation and health education.

Pacientes em tratamento de hemodiálise devido ao seu sistema imunológico diminuído são facilmente acometidos por enteroparasitas, que levam a uma piora do quadro de saúde destes indivíduos. O objetivo desta pesquisa foi identificar a prevalência de enteroparasitas nos pacientes renais crônicos em tratamento de hemodiálise e possíveis associações com os fatores socioambientais. Trata-se de um estudo transversal com 53 pacientes. Para análise de associação foi utilizado os testes qui-quadrado (x²) de Pearson e Razão de Odds (OR). Os exames coprológicos foram analisados utilizando as técnicas de Hoffman e Sheather. A positividade de enteroparasitas atingiu 92.5%, sendo Blastocystis sp. o mais predominante (95.9%). Em relação aos helmintos, apenas Ascaris lumbricoides foi encontrado (4.1%). Infecções mistas apareceram em 53% dos casos. A associação dupla mais comum foi entre Blastocystis sp. e Endolimax nana, observada em 22.4% dos casos. Nossos resultados mostraram alta prevalência de protozoários de repercussão preocupante para saúde desses pacientes como Cryptosporidium sp., Giardia lamblia e Entamoeba histolytica, evidenciando a necessidade de estratégias de prevenção das infecções parasitárias e intervenções adequadas nos pacientes sob tratamento de hemodiálise.

The present study was conducted to evaluate the infection rates of Entamoeba histolytica, Entamoeba dispar, and Entamoeba moshkovskii among asymptomatic individuals in Erbil City, northern Iraq. The research intent was to discover whether pathogenic or nonpathogenic species cause a high rate of symptomless Entamoeba infections. Stool samples were microscopically examined, and the 18S-rRNA gene was targeted utilizing the nested PCR technique in the positive specimens. Initial results based on morphological features showed that the Entamoeba prevalence rate was 7.4%. Significantly higher rates of infections were seen in females than in males and in low-income people than in moderate-income people. The incidence rates among the asymptomatic individuals, as determined by molecular analysis, were as follows: E. histolytica - 6%, E. dispar - 4.3%, and E. moshkovskii - 0.3%. Of all the Entamoeba positive samples, a single infection with E. histolytica was identified in 41.4% samples; the single infection with E. dispar in 18.6% samples, 35.7% samples had mixed infections with two Entamoeba species, and 4.3% had mixed infections with three species. The current study concluded that 7.4% of healthy people, who live in the endemic area under investigation, carry Entamoeba species asymptomatically. Additionally, the majority of asymptomatic Entamoeba infections were caused by the pathogenic E. histolytica (81.4%) compared to E. dispar (58.6%), and E. moshkovskii with the lowest rate of infection. Single and co-infections with E. histolytica and E. dispar were noted. E. moshkovskii, which was identified for the first time in the region, was only seen in mixed infections.

Vorinostat is a drug used to treat cutaneous T cell lymphoma whose action mechanism is based on Histone Deacetylase inhibition. Histone Deacetylases are a family of enzymes that remove acetyl groups from histone and non-histone proteins that control many crucial processes, such as gene regulation, cell cycle progression, differentiation, and apoptosis. Histone Deacetylase homologues are also expressed in parasites of the genus Plasmodium, Leishmania, Cryptosporidium, Schistosoma, Entamoeba, and others. In this way, antiparasitic properties of Vorinostat have been explored. The aim of this review is to report the current state knowledge of Vorinostat as antiparasitic drug against Plasmodium, Leishmania, Cryptosporidium, Schistosoma and Entamoeba in order to support future investigation in this field. The authors revised the recent and relevant literature concerning the topic and discussed advances and limitations of studies on Vorinostat as potential drug to treat human parasitic diseases. Vorinostat has been efficient in vitro and, in some cases, in vivo, against parasites that cause parasitic diseases, such as malaria, leishmaniasis, cryptosporidiosis, amoebiasis, and schistosomiasis. In vitro and in vivo models have demonstrated the antiparasitic activity of Vorinostat, however, the challenge is to assay its activity in animal models and to evaluate if Vorinostat is safe for humans as new alternative to treat human parasitic infections.

Amoebosis, caused by the protozoan parasite Entamoeba histolytica is a gastrointestinal infection and the second leading cause of death from parasitic disease worldwide. The disease is endemic in many developing countries and kills over one hundred thousand persons annually. Adequate nutrition composed of macro- and micronutrients in their balanced proportions is central to effective gut immune response and the homeostasis of commensal organisms in the gastrointestinal tract. Entamoeba histolytica is a gut pathobiont that can exploit a shift in nutritional status to cause amoebosis, with extra-intestinal complications. Although undernutrition is rarely a public health concern in high income settings, bioavailability of functional nutrients remains suboptimal. On the other hand, nutrient deficiencies constitute a chronic challenge in very low-income regions. This study sought to review the pivotal influence of malnutrition on intact microbiota and functional immunity, as determinants of susceptibility to amoebosis in the Nigerian example of tropical regions. The dynamics of the infection such as possible coinfection with opportunistic pathogens were also, evaluated. Based on the available reports, we posit that amoebosis is a common tropical infection perpetuated by malnutrition following poor living standard including unhygienic environmental exposure.

Metronidazole (MTZ) is a potent drug used against protozoa such as Entamoeba histolytica, Giardia lamblia, Trichomonas vaginalis, and Balantidium coli, anaerobic bacteria, amebic liver abscess, bacterial meningitis, infection of the bone, and infectious disorder of the joint. Common side effects of MTZ include mild abdominal pain, headache, nausea, and persistent metallic taste, while other serious and rare side effects include pseudomembranous colitis, seizures, encephalopathy, and peripheral neuropathy. A case of MTZ-induced peripheral neuropathy has been included in this article. A patient was prescribed MTZ for liver abscess for 4 weeks; the patient developed peripheral neuropathy in 15 days; immediately, he reached the hospital and MTZ was withdrawn. He has then been prescribed pregabalin to treat peripheral neuropathy. The patient improved in 4 days on this treatment and was discharged from the hospital. This study concludes that MTZ has a rare side effect of peripheral neuropathy.

Intestinal parasitic infections such as strongyloidosis are more common among individuals with immune deficiency and sometimes accompanied by severe symptoms. The purpose of this cross-sectional study was to evaluate the prevalence of intestinal parasites with focus on strongyloidosis in hospitalized patients. A total number of 566 faecal samples were obtained from different wards and assessed by the use of direct smear, formalin-ether concentration, and agar plate culture procedures in order to find parasitic protozoa and helminthes. The findings revealed that 10.1% (n=57) of the examined samples were positive for intestinal parasites. The highest prevalence rate was related to Entamoeba coli (4.6%, n=26) and the lowest one was related to Strongyloides stercoralis (0.5%, n=3). In addition, Giardia lamblia prevalence rate was 3.2% (n=18) and the prevalence rate of Blastocystis hominis was 1.8% (n=10). The sensitivity of S. stercoralis diagnosis was equal for agar plate culture and formalin-ether concentration methods. This study demonstrated the significance of focus on intestinal parasites in hospitalized patients and highlighted the necessity of improving the insight in health care providers about the occurrence of parasitic infections especially strongyloidiasis in these patients.

Parasites are transferred between domestic and wild animals, when host animals come in contact with each other, particularly while grazing the same pastures, or when using same water bodies for drinking. Chances of parasite transmission and adaptation are high when hosts are genetically related. Afghan urial (Ovis vignei blanfordi), Suleiman markhor (Capra falconeri jerdoni) and Chiltan wild goat (C. aegagrus chialtanensis) are wild kin of domestic sheep and goats, sharing numerous parasitic diseases with each other. The present study was conducted in 2014–2015, to determine parasitic infections of Suleiman markhor and Afghan urial of Torghar Game Reserve, and the endemic wild goat of Chiltan National Park. For comparison, parasites of domestic small ruminants of these areas were also studied. A total of 11 species of helminth and 20 species of protozoa were recorded. Highly prevalent helminth among wild ruminants were Trichuris spp., Nematodirus spp., Protostrongylus rufescens and Moniezia benedeni, while highly prevalent Eimeria were E. arloingi and E. ninakohlyakimovae in caprines and E. ovinoidalis in urial. Chiltan wild goats were also found infected with Entamoeba spp. A short tabulated review of the helminth and protozoan parasites of wild sheep and goats of Pakistan, India, Iran and Turkey has been presented.

Discusión: Se observa una disminución en la prevalencia de estos microorganismos, considerando la mejora de los servicios básicos en la zona y educación sanitaria, siendo frecuente en el sexo femenino, y el grupo etario que presento mayor parasitosis es de 1 a 5 años, siendo la Entamoeba histolytica la de mayor presencia y no existe relación en la frecuencia de protozoariasis intestinal en relación con otros trabajos de la región.

Study of relationship between host and parasite is always very important to find out mode of infection, pathogenisity and transmission of any disease. Large number of parasites are known for infecting plants and animals. Members of genus Entamoeba are Sarcodine Protozoans. Entamoeba histolytica is parasite of primate mammals including man causing amoebic dysentery. Entamoeba invadence is parasite of cold blooded reptiles specially found in Python. Entamoeba is transmitted in encysted stage; the cyst formation facilitates the survival and spreading of the pathogen from one infected host to other healthy host. Entamoeba feeds upon starch grains, R.B.C. (Red blood cells), cells of mucosa of alimentary canal and bacteria. A number of bacteria are used as food by amoeba including Mycobacteria, the causative agent of tuberculosis, leprosy and other associated infections. On using mycobacteria as only source of food to entamoeba, it was observed that it feeds actively on some species of mycobacteria and grows normally but in presence of some other species of mycobacteria which forms toxic substances as metabolic by-products entamoeba stops feeding and fails to grow. Some species of mycobacteria form certain enzyme which inactivates the digestive enzymes secreted by the phagocyte in phagosome so bacillus remains unaffected in protoplasm of phagocytic cell or amoeba and divides normally in phagocytic cells. Mycobacterium lucknowense is a isolated from frog Rana tigerina is a acid fast, scotochromogenic, rapid growing bacilli, pathogenic to experimental animals causing tuberculosis and leprosy like symptoms. Studies on this bacillus were done to observe that (1) Dose Ent amoeba feeds on Mycobacterium lucknowense. (2) Is these mycobacteria is digested in food vacuole or divides normally. (3) Is cyst formation of en tam oeba is affected. The observations showed that Mycobacterium lucknowense actively eaten up by en tam oeba but was not digested in food vacuole, divides normally and encystment of en tam oeba is not favoured.

Amoebic liver abscess (ALA) is the main extra-intestinal complication caused by Entamoeba histolytica. Given the histological features of ALA in hamsters and the importance of the vagus nerve in the immune response, the aim of this study was to identify and analyze the major changes in ALA that are caused by a vagotomy. The changes found are related to inflammatory foci and abscess size, the type of collagen formed, and the number of trophozoites in lesions. Male hamsters were divided into three groups: Intact animals (IA) and those undergoing a false operation (SHAM) or a subdiaphragmatic vagotomy (VAG). In each group, E. histolytica trophozoites or culture medium (CM) were inoculated in hamsters by the intrahepatic route, and then euthanized at 6h, 12h, 24h, 48h, 4d or 7d post-infection. Initially the growth of the abscess was more rapid in the VAG group, but at day 7 it was faster in the IA and SHAM groups. VAG animals showed a higher quantity of type III collagen than the IA and SHAM groups. A larger number of amoebic trophozoites/mm² was observed up to day 4 in VAG hamsters (23.3±2.19) compared to IA (14.6±0.23) and SHAM (6.13±0.87) animals. This parameter decreased by day 7 in VAG (13.4±0.87) with respect to IA (24.7±1.47) and SHAM (21.7±1.48). The results show that a subdiaphragmatic vagotomy influenced the development of ALA in hamsters, suggesting a modification of the morphological structure of damaged hepatic tissue.

BACKGROUND: Vegetables are vital for good health but can serve as a means of transmission of parasitic pathogens to man. JUSTIFICATION: There is increase consumption of vegetables due to general awareness of the health benefits. This research intends to explore suggestive management strategies and control in handling vegetables to reduce or if possible eliminate food borne parasites. AIM AND OBJECTIVE: The study was to determine parasitic contamination of fresh vegetables with objective to determine the prevalence of parasites of medical importance in vegetables sold in Jos market. METHODOLOGY: A total of 575 samples of fresh vegetables; Lettuce, Cabbage, Carrot, Spinach, Green Pepper, Cucumber, Beetroot, Tomatoes, Garden egg, and Green bean; were bought from sellers from May-June 2016 and examined for helminthes eggs, larva and cysts using wet mount and concentration techniques. RESULT: Hookworm, Ascaris lumbricoides, Trichuris trichuria, Strongyloides stercoralis, cyst of Entamoeba histolytica and Giardia lambia accounted for 7.3%, 8.1%, 4.8%, 58.1%, 9.7% and 12.1% respectively. Cucumber, carrot, cabbage beetroot, spinach, lettuce, green pepper, green beans, garden egg and tomatoes had 0%, 26.7%, 31.7%, 5.7%, 40%, 53.3%, 6.7%, 6.7%, 13.3% and 25% respectively with overall prevalence of 21.6% and strongyloides stercoralis was most prevalent and Trichuris trichiura least prevalent found in cabbage and tomatoes. Lettuce has the highest contamination rate 32(53.3%), followed by spinach 24(40%) while beetroot had the least (5.7%). CONCLUSION: Vegetables in Jos Metropolis are contaminated with parasites. There should be proper washing as they could serve as source of transmission of parasites when eaten raw or undercooked.

Long-tailed macaque (Macaca fascicularis) belongs to least concern categories of animals, and often found in various regions of Indonesia, including Kupang, East Nusa Tenggara. Their habitat are one of the tourist destinations, causing interaction between them and humans. The interaction facilitates the transmission of disease agents, for example endoparasit. This study was conducted to find out the diversity and prevalence of endoparasites in long-tailed macaque, weather effects, and zoonotic potential in Kupang City. Fifty fecal samples were collected and analyzed using formalin ethyl acetate concentration technique (FECT). A total of six endoparasites were recovered including four helmints (hookworm, Strongyloides, Toxocara, and Acantocephala) and two protozoans (Balantidium coli and Entamoeba sp.). The highest prevalence of infection occurred in February (rainfall 302.4 mm) and consisted of hookworm (86%) and B. coli (66%). If rainfall increases, prevalence will also increase. The high prevalence of parasites is not always associated with the appearance of clinical symptoms. An individu diagnosed with parasites if the eggs or cysts have been identified from the faeces. The high prevalence caused by the absence of deworming program. Among the endoparasites that have been found, some of which are potentially zoonotic, such as: Strongyloides sp., Toxocara sp., Acanthocephala, B. coli, and Entamoeba sp.

The majority of the population in Yemen lives in rural areas and suffers from parasitic infections. Therefore, the present study aimed to determine the prevalence of intestinal parasitoses and schistosome infections among the students enrolled in the primary schools in Hajjah governorate – north of Yemen, along with an assessment of praziquantel (PZQ) in the treatment of microscopy-confirmed cases of Schistosoma mansoni and Schistosoma haematobium. For this purpose, 780 samples (320 stool and 460 urine) were examined microscopically. The present study revealed an overall infection rate of 75.3% (241/320) with intestinal parasites and Schistosoma mansoni. The detected parasite species included Entamoeba histolytica (27.8%), Hymenolepis nana (12.2%), Giardia lamblia (9.7%), Entamoeba coli (9.4%), S. mansoni (9.1%), Ascaris lumbricoides (6.9%), Trichuris trichiura (3.1%), Enterobius vermicularis (2.8%) and Ancylostoma duodenale (2.2%). Schistosoma haematobium was prevalent among 1.7% (8/460) of the investigated students. On the other hand, PZQ yielded a cure rate of 75.7% of Schistosoma-infected students when administered at 40 mg/kg body weight. However, a 100% cure rate was achieved when administered at 60 mg/kg body weight. Therefore, the findings of the present study highlight the importance of monitoring PZQ efficacy through large-scale studies in different settings endemic for schistosomosis in the country.

La población infantil tiene mayor probabilidad de ser afectada por enteroparasitosis, debido a la inmadurez inmunológica y que sus hábitos higiénicos aún se encuentran en desarrollo. Se realizó un estudio observacional, descriptivo, con enfoque mixto; cuya población objeto de investigación estuvo constituida por 382 escolares de la Unidad Educativa del Milenium. Cantón Penipe, Ecuador, cuyas edades oscilaron entre 5 y 11 años. Se realizó un muestreo no probabilístico por conveniencia, a partir del cual se seleccionaron 133 alumnos matriculados desde el primero a séptimo año de educación básica, durante el periodo octubre 2017 – febrero 2018, los cuales se habían realizado exámenes de heces fecales en los últimos seis meses, y cuyos tutores legales emitieron el consentimiento informado. Entre los individuos estudiados prevaleció el género femenino. La mayoría de los pacientes no presentaban parasitismo intestinal (53,38%). La incidencia parasitaria es más frecuente en niños con edades comprendidas entre los 8 y 10 años, para un 54,13%. Entre los informes con positividad, se observó un predominio del reporte de Entamoeba coli (48%) y Entamoeba histolytica con un 42%. La mayoría de los casos positivos mostraron poliparasitosis.
