Blastocystis Spp

Intestinal parasites are a problem for public health all over the world. The infection with Blastocystis, a protozoan of controversial pathogenicity, is one of the most common among them all. In this study, the occurrence of intestinal parasites, with emphasis on Blastocystis, in patients at the Universidade Federal do Triângulo Mineiro was investigated in Uberaba (MG) through microscopy of direct smears and fecal concentrates using Ritchie’s method. Feces of 1,323 patients were examined from April 2011 to May 2012. In 28.7% of them at least one intestinal parasite was identified, and the most frequent organisms were Blastocystis spp. (17.8%) and Giardia intestinalis (7.4%). The occurrence of parasitism was higher in children aged 6 -10 years old, and the infection with Blastocystis spp. was higher above the age of six (p < 0.001). The exclusive presence of G. intestinalis and of Blastocystis spp. was observed in 5.4% and 12.2% of the patients, respectively. Regarding patients with diarrheic feces, 8% revealed unique parasitism of Blastocystis spp. Other intestinal parasites observed in children were Ascaris lumbricoides (0.3%) and Entamoeba histolytica/dispar/moshkovskii (1.4%). The Ritchie’s method was more sensitive (92.8%) when compared to direct microscopy (89.8%), with high agreement between them (97.7%, kappa = 0.92). In conclusion, the occurrence of Blastocystis spp. in Uberaba is high and the presence of diarrheic feces with exclusive presence of the parasite of Blastocystis spp. was observed.

A total of 200 stool samples were examined and five species of intestinal parasites were identified. Two of them were protozoans (Entamoeba histolytica and Giardia intestinalis) and the rest of which three species were nematode parasites (Ascaris lumbricoides, Trichuris trichiura and Strongyloids stercoralis). The overall prevalence of parasitic infection was 50%. Individually the prevalence of Ascaris lumbricoides, Entamoeba histolytica, Giardia intestinalis, Trichuris trichiura and Strongyloids stercoralis was 25%, 13%, 6%, 3.5% and 2.5%, respectively. Patients of different age and sex had a variable degree of infection. Children aged under ten years showed the highest prevalence (73.97%) compared to other groups. Accordingly, male patients were found slightly more susceptible to the infection (50.38%) compared to the female (49.29%). People belonging to different occupation and educational qualification had various degree of infection. As expected patients who had no education and poor monthly income, showed the highest prevalence of infection, 77.77% and 90%, respectively. Personal hygiene practices of the patients had much influence on the parasitic prevalence and rate of infection. Respectively 58.82%, 91.42%, 80% and 63.55% prevalence were found among the patients who used to drink unsafe water, wash hands without soap, stay barefooted most of the time and do not trim their nails regularly. The present study supposed to reveal that socioeconomic conditions and behavioral factors may influence the prevalence of parasitic infections. Bangladesh J. Zool. 47(1): 129-136, 2019

Stool samples from 122 children from urban slum (n = 72) and rural (n = 50) areas were analyzed using multi-parallel real-time qPCR to determine the prevalence of intestinal parasites from two communities in Colombia. Findings indicated a prevalence of 86.1% Blastocystis spp., 62.5% Giardia intestinalis, 19.4% Cryptosporidium spp., 19.4% Ascaris lumbricoides, and 5.6% Trichuris trichiura in an urban slum; and 76% Blastocystis spp., 68% Giardia intestinalis, 20% Entamoeba histolytica, 50% Ascaris lumbricoides, 46% Trichuris trichiura and 2% Strongyloides stercoralis in rural areas. Polyparasitism was higher in rural (58%) compared to urban (25%) areas (p = 0.001). Trichuris trichiura burden was higher in the rural area (p = 0.002). Over 40% of helminth infections in rural areas had a heavy parasite burden by WHO classification. Over half of urban and rural children were infected with Giardia intestinalis and Blastocystis spp. Our data provides accurate epidemiologic surveillance for public health interventions.

Introduction: Intestinal parasitic infections are among the main problems in developing countries. It is estimated that over 4.5 billion people in the world have been infected with a variety of intestinal parasites. Numerous studies conducted in different parts of Iran showed the spread of intestinal parasite infections in different urban and rural areas. However, the prevalence of these infections significantly reduced in recent years due to improvements in public health. Methods: In this cross-sectional study conducted in a hospital in Tabriz city of Iran, 700 stool samples were collected during one year and studied using formalin-ether concentration method and Lugol’s iodine staining. Results: In this study, six types of parasites including Giardia lamblia, Entamoeba histolytica, Entamoeba coli, Chilomastix mesnili, Blastocystis hominis, and Enterobius vermicularis were detected in 700 fecal samples. A total of 112 (16%) samples were infected, among which 43 (40%) were infected with Giardia lamblia, 35 (32%) with Entamoeba histolytica, 20 (18%) with Enterobius vermicularis, 10 (9%) with Entamoeba coli, 3 (0.026%) with Blastocystis hominis, and 1 (0.008%) with Chilomastix mesnili. Conclusion: In this study, the highest prevalence of infection belonged to Giardia lamblia (40%), which is consistent with the statistics published by the World Health Organization. According to the findings of this study, it can be concluded that despite the increase in the provision of health services in cities and villages, the prevalence of intestinal parasites, especially Giardia lamblia, is one of the major problems in the region. Therefore, there is a need for proper and coherent health planning in the region and accurate and up-to-date epidemiological information.

Intestinal Parasitic Infection

Intestinal parasitic infections have always been an important public health problem in the tropics particularly in developing countries such as Nigeria for example. A cross-sectional survey involving 440 schools going children of both sexes aged 6 - >12 years was conducted in 4 primary schools at a different location in Doma Local Government Area (LGA) of Nasarawa State, Nigeria, between September 2015 to February 2016 to determine the prevalence of intestinal parasites. Of the 440 samples examined 155 (35.22%) were infected with different intestinal parasites. The parasites observed included Entamoeba histolytica (6.59%), bookworm (5.22%), Ascaris lumbricoides (53.40%), Trichuris trichiuria (0.45%), E. coli (4.77%) and mixed infection of Ascaris lumbricoides and hookworm (7.27%) with Ascaris lumbricoides having the highest prevalence. Doma south primary school 38 (34.54) Islamiyya nursery/primary school and Doma west primary school had the lowest prevalence with 36 (32.72%) and 34 (30.90%) respectively. An overall prevalence of (35.22%) intestinal parasitic infection in school going children is moderately high and of public health concern. There is need to intensified integrated control measure to reduce or completely eradicate the intestinal parasitic infection in school pupils.

Introduction: The parasites can cause different gastrointestinal disorders which have great impact on life quality. Hearing and speech impaired children are unable to maintain proper sanitation, making them more prone to intestinal parasitic infection. Aim and Objective: To know the prevalence of various parasitic infestations among hearing and speech impaired Children. Materials and Methods: Stool specimen were collected from 104 hearing and speech impaired children who were living in private rehabilitation school of chisapani village of Banke district Nepal for a period of 5 month from December 2017 to April 2018 and direct wet mount was prepared using normal saline (0.9%) and Lugol's iodine (0.5%). The wet mount was observed under microscope for parasites. Results: Among 104 individuals intestinal parasites were seen in 25.96 % of students. Giardia lamblia (37.04%) was the most common parasite followed by Ascaris lumbricoides (18.52%) and Entamoeba histolytica (14.82%). Conclusion: The study shows that although the speech and hearing impaired children are more prone to parasitic infection, the prevalence is same as normal people. Giardia lamblia, Ascaris lumbricoides and Entamoeba histolytica were the common parasites. Prompt diagnosis and treatment of infected children should be undertaken.

Fresh vegetables are frequently used to prepare fresh salad dishes widely consumed in the world. They are known to be the main source of pathogenic intestinal parasites. In this context, the present work aimed to (a) detect the pathogenic intestinal parasites (PIP) in washed fresh vegetables, and (b) assess the exposure to PIP in the city of Ain Témouchent (Algeria). In fact, 26 samples belonging to six groups of fresh vegetables (cabbages, lettuces, leeks, radishes, peppers and tomatoes) were collected, washed (similarly to domestic wash with or without vinegar addition), then examined for PIP contamination. The results indicated that 90% of the examined vegetable samples were contaminated with intestinal parasites showing higher prevalence in lettuce (70.85%) while the lowest contamination (23.52%) was reported in pepper. In addition, Cryptosperidium (72%) has been found to be the most dominant parasite in all vegetables while Toxocara (8%) was less present. These finding are a preliminary report to conduct a risk assessment of PIP linked to vegetable feeding

Every year, the number of people living with HIV rises as a consequence of advanced infections and the positive effects of highly active antiretroviral therapy (HAART). Gastrointestinal involvement is common, with 90% of patients seeking treatment for gastrointestinal problems as their HIV infection progresses. Nonetheless, identifying and characterization of infectious agents is important for patient management by excluding a clinical diagnosis and determining appropriate treatment, as well as determining public healthcare policy for true pathogen prevalence and yielding epidemiological risk factors for specific infections. The aim of this study is to evaluate the prevalence of symptomatic or asymptomatic intestinal parasitic infection among HIV or AIDS patients. For this study with 80 HIV seropositive patients being recruited from various wards and the Integrated Counseling and Testing Center (ICTC) affiliated to the microbiology department. Patients with acute and chronic diarrhea with abdominal disorder were taken as symptomatic whereas patients without these clinical complaints and who came for routine investigations were taken as asymptomatic. Firstly stool samples were analyzed by macroscopically for the presence of mucus, blood, larvae, segments of tapeworm and adult worms. The consistencies of stool were also recorded such as formed, watery or soft or loose with odor and color. It was examined microscopically after macroscopically for protozoan cysts and trophozoites, helminthic ova and larvae, as wet mount preparation by saline and iodine preparation as well as formal ether concentrated. For the detection of intestinal coccidian parasites, smears were prepared from stool samples and a modified Ziel-Nelseen (MZN) stain was also performed. Stool samples with the detection of parasites were informed for treatment. The prevalence of intestinal parasite was 23.75% with asymptomatic and symptomatic groups having a prevalence of 16.98% and 37.04% respectively. Out of total patients, 56.25% were male and 43.75% were female. Among the male patients, 11 (13.75%) were positive for an intestinal parasitic infection and 8 (10%) were positive among females. The age distribution data revealed that the age group 21-40 years old had the highest number of intestinal parasites, followed by 41-60, 61-80, and 0-20 years old. The most intestinal parasites were found in the young and middle-aged patients, according to this study. Different parasites were identified as Entamoeba histolytica, Taenia species, Ascaris lumbricoides, Cryptosporidium parvum and Isospora with one protozoan, two coccidian parasites and two helminthes. The most common parasite was Taenia species 6 (7.5%) followed by Entamoeba histolytica 5 (6.3%) and Cryptosporidium parvum 5 (6.3%). Intestinal parasitic infection is not uncommon in HIV seropositive patients. This study underscores the need for early diagnosis and treatment of these intestinal parasites in both symptomatic and asymptomatic HIV patients.

Nigeria is among the countries with the highest population cases of infections with intestinal parasites in sub-Saharan Africa. The increase in consumption of leafy and root vegetables by population in Kano metropolis necessitated the need for a study to assess the types and scope of these parasitic organisms in vegetables consume in urban Kano. Vegetables produce obtained from most markets within Kano metropolis are mostly sourced from nearby irrigation farms that used relatively contaminated waters which provides suitable growth condition for disease causing organisms. This research study determines the presence of parasites of health importance and their level of contamination in selected vegetables (cabbage, lettuce Cucumber, carrot and onions) sold at various markets in Kano metropolis. Vegetable samples were purchased randomly under normal purchased conditions and about 200g each was weighed and washed according to the generally used method for washing vegetables. The samples were eluted followed by sonication in an already prepared buffered solution, filtered and examined for the presence of cysts, oocysts, and helminthes eggs and larvae. The eggs/cysts of Ascaris lumbricoides, Entamoeba species, Giardia intestinalis and Trichuiris species were observed. Among all the four markets involved in the study, “GanaKwari market recorded the highest number of eggs/cysts, been present in all the samples, followed by Kwa-kwaci Market with the presence of eggs/cysts in all the samples excluding cabbage. These are followed by Kofar Naisa market with all the samples contaminated but with less number of eggs/cysts. However, Sharada market recorded the lowest level of contaminants with only three of the samples containing eggs/cysts. However, among all the (5) samples collected, onions recorded the highest contamination, followed by cabbage and lettuce having the same, then cucumber and lastly carrots. The variation in the level of contamination among these markets may be attributed to the market type and the different water sources and means of display of these vegetables.
