Abstract Intestinal parasitic infections in immunocompromised patients can lead to serious complications when not diagnosed and treated early. This study aimed to investigate the frequency of intestinal parasites in cancer patients undergoing chemotherapy in the South of Brazil. Three fecal samples collected from each patient (73 individuals) were processed by Ritchie and Faust techniques and submitted to specific staining methods for intestinal protozoa. A 61.6% parasite and/or commensal positivity was found. Helminths identified were Ascaris lumbricoides (33.3%), Taenia spp. (6.6%), Strongyloides stercoralis (4.4%) and Trichuris trichiura (2.2%). Among protozoans, Giardia lamblia (26.6%), Cryptosporidium spp. (13.3%) and Cystoisospora belli (4.4%) were identified. The presence of Entamoeba coli, Endolimax nana and Entamoeba hartmanni was also recorded. The results obtained warn of the importance of fecal parasitological diagnosis and the use of specific staining methods for the detection of intestinal parasites in cancer patients. These exams should be regularly requested at the patient’s first clinic visit, given the high prevalence found in this study and the possible severity of such conditions for these individuals.

Intestinal Parasitosis

Introduction: Nowadays in our state, intestinal parasitic diseases are still endemic, with a greater frequency in rural and mountainous urban areas. After the years have elapsed since the last national survey, it was necessary to carry out a new survey to know the prevalence rates of intestinal parasitosis and to compare the results obtained between both studies. Such knowledge would be of great value in developing health strategies and designing intestinal parasitic infection control programs. Objective: to determine the current prevalence rates of intestinal parasites, to compare the results with those of the survey obtained. Methods: a random cross-sectional descriptive study was carried out during the months of December 2018 to March 2019 in a random sample of both sexes from the population of urban communities and the province of Zacatecas, Zac. Each one had a stool sample collected that was analyzed by the direct examination method, the Willis concentration technique, and the Kato-Katz examination; A questionnaire was also applied to them. Results: when comparing the results of the national and state surveys of intestinal parasitic infections carried out in 2009 and 2018, it was found that, in general, infections by parasites decreased, both helminths and pathogenic protozoa, although those infected with commensals increased their frequency in that of 2019. There was also a decrease in the frequency of infections by all species of soil-transmitted helminths, Trichuris trichiura, Ascaris lumbricoides, ancylostomideos, and Strongyloides stercoralis, as well as by the pathogenic protozoa Giardia lamblia and Entamoeba histolitica. Conclusions: when comparing the results of national and state surveys of intestinal parasite infections carried out in 2018 and 2019, it was found that in general the frequencies of infections with intestinal parasites decreased. The finding in both studies of a higher frequency of infection with parasites or commensals in the group aged 5 to 14 years (school age), supports the recommendation to place emphasis on control programs for intestinal parasites in this age group.

Introduction: Patients with cancer and hemodialysis are prone to opportunistic infections. The present research aims to examine the frequency of Toxoplasmosis and intestinal parasites in these patients. Methods: In the present cross-sectional study, seventy stool and blood samples from immunocompromised patients (46 hemodialysis and 24 cancer patients) from Guilan Province were collected in 2017-2018. Different tests including direct smear examination and formalin-ether was conducted for the intestinal protozoan parasites. To detect coccidian parasites (e.g. Cryptosporidium spp.) Ziehl Neelsen staining was applied. The anti T.gondii antibodies were detected via ELISA method. Results: Totally 6.52% and 4.16% cases of hemodialysis and cancer patients were positive for intestinal parasite infection respectively. Blastocystis hominis was only intestinal parasite that were detected in these patients. IgG anti-Toxoplasma antibody detected in 35 (76.8%) hemodialysis and 15 (62.5%) cancer patients. IgM antibody were found in 1 elderly hemodialysis patient. Mix infection (Toxoplasmosis and Blastocystis) was observed in 6.52% and 4.16% in hemodialysis and cancer patients respectively. Conclusion: It is recommended to evaluate these patients for intestinal parasitic infections during hemodialysis or chemotherapy sessions. Data showed the high percentage of elderly patients were susceptible to reactivation of chronic Toxoplasmosis. Therefore, in order to refer them for early therapy or other interventions, it is important that elderly hemodialysis and cancer patients with toxoplasma infection be diagnosed and identified.

Parasitological examinations were carried out during July to December, 1989, on 485 inhabitants of four villages in São Lourenço da Mata, 25 km northwest of Recife, Pernambuco, Brazil. Approximately 99.6% of the inhabitants were infected with at least one species of intestinal parasites. A high prevalence of Schistosoma mansoni (82.1%), hookworm (80.2%) Trichuris trichiura (69.9%), Ascaris lumbricoides (61.9%) and Entamoeba coli (36.7%) infections were demonstrated. Test tube cultivation revealed that the most common species of hookworm in this region was Necator americanus (88.4%), and also that the prevalence of Strongyloides stercoralis was 5.8%. Three hundred and thirty-four sera were serologically examined for amoebiasis by the gel diffusion precipitation test (GDP) and enzyme-linked immunosorbent assay (ELISA). No positive reaction was observed in all sera as examined by GDP, while 24 sera were positive by ELISA.

Abstract Buffaloes represent an important economic resource for several regions of the world including Romania; however, no reports on parasitic infections in buffaloes from Romania are available. In the present study, we examined for the gastrointestinal parasites 104 fecal samples bimonthly collected from 38 buffalo calves (2–11 weeks old) from household rearing systems in Romania. All samples were tested using the saturated salt flotation, McMaster and modified Ziehl-Nielsen staining methods. PCR coupled with isolates sequencing methods were used to identify the Giardia duodenalis assemblages and Cryptosporidium species. Overall, 33 out of 38 examined buffalo calves were infected with different gastrointestinal parasites; 16 had single infections and 17 had mixed infections with 2 or 3 parasites. Eimeria species (32/38; 84.2%) was the most prevalent parasite; 8 species were identified according to the oocyst morphology including the pathogenic E. bareillyi which detected for the first time in buffaloes from Romania. Toxocara vitulorum (11/38; 36.8%) and Strongyloides papillosus (6/38; 15.8%) were also detected. Cryptosporidium spp. were found in 4 (10.5%) buffalo calves; 2 of them were molecularly identified as C. ryanae and another one was clustered in the same clade with C. ryanae, C. bovis, and C. xiaoi. Giardia duodenalis assemblage E was also molecularly detected in a single (2.6%) buffalo calf. The presence of other buffaloes in the same barn was identified as a risk factor for infection with T. vitulorum. Our results indicate extensive parasitic infections in buffalo calves from Northwestern Romania and underline the necessity of prophylactic treatments for T. vitulorum and E. bareillyi.

Background: Consumption of raw or unhygienically prepared vegetables is a potential source of parasitic infection. This study aimed to establish the prevalence and types of intestinal parasites on the freshly sold vegetables at the market. Methods: Totally, 95 vegetable samples were randomly procured from vendors at Lusaka City market (Zambia). The samples were examined for parasitic contamination using floatation and sedimentation methods. Data were analyzed using Epi Info version 7.2.4.0. Results: The overall parasitic contamination of fresh vegetables was 35.8% (34 out of 95). The highest parasitic contamination rate was found in Chinese cabbage with 7.4% (7 out of 95), followed by rape with 6.3% (6 out of 95), chilli with 5.3% (5 out of 95), pigweed with 5.3% (5 out of 95), pumpkin leaves with 5.3% (5 out of 95), tomatoes with 4.2% (4 out of 95), and cabbage with 2.1% (2 out of 95). There was a significant (p=0.001) statistically difference between the type of vegetables and the presence of the parasites. The identified helminths had different prevalence rates, including Taenia spp. with 9.5%, Trichuris trichuria with 5.3%, Ascaris lumbricoides with 3.2%, Clonorchis sinensis with 2.1%, Diphyllobothrium latum with 2.1%, Paragonimus westermani with 2.1%, and Strongyloides stercoralis with 2.1%. Also, Giardia lamblia with 24.2% and Balantidium coli with 4.2% were the protozoan parasites identified. Conclusion: This study showed that some vegetables sold at the Lusaka City market (Zambia) were a potential source of parasitic infections for local consumers. G. lamblia was the most prevalent parasite found in the vegetable samples.

AbstractIn order to determine the prevalence of intestinal parasites among labourers from Thailand in Taiwan, the stool samples from 1364 Thai labourers were examined by the formalin-ether concentration method and 18·0% were found to be infected with one or more parasites. The infection rates of hookworm, Opisthorchis viverrini, Strongyloides stercoralis, Enterobius vermicularis, Ascaris lumbricoides, Hymenolepis nana, Capillaria philippinensis, Schistosoma japonicum, Echinostoma sp., Entamoeba coli, Giardia lamblia, and Entamoeba histolytica, were 7·6%, 7·0%, 3·2%, 0·5%, 0·3%, 0·1%, 0·1%, 0·l%,0·l%, 0·4%, 0·2%, and 0·1% respectively. The prevalence was highest among the 21–25 age group (24·8%). Among the 245 infected persons, 91% were infected with one parasite, 8% with two parasites and 1% with three parasites. The finding that parasitic infections are prevalent among Thai labourers demonstrates the need for control measures in foreign labourers in Taiwan and further studies to determine the susceptibility of O. viverrini to the snail hosts of Clonorchis sinensis.

Background. Intestinal parasites and Schistosoma mansoni infections adversely affect the health of humans in the world especially in sub-Saharan African countries including Ethiopia. Fishermen who spend most of their time in water bodies are supposed to be at high risk of schistosomiasis and other water-born parasites. However, the magnitude of these parasitic infections and their determinant factors are not well addressed. Methods. A cross-sectional study was conducted at Lake Tana among 388 fishermen from March to May 2021. Questionnaire data was collected through face to face interview. Stool sample from each participant was processed by the Kato-Katz and spontaneous tube sedimentation techniques. Data were analyzed using SPSS version 26. Results. One hundred sixty four (42.3%) and 88 (22.7%) participants were infected by intestinal parasites and Schistosoma mansoni, respectively. One hundred twenty two (31.4%) and 42 (10.8%) participants were infected by soil-transmitted helminths and intestinal protozoa, respectively. Attending only primary school ( AOR = 2.02 , p = 0.014 ) or being illiterate ( AOR = 2.54 , p = 0.004 ) and not washing hands before meal ( AOR = 2.23 , p = 0.007 ) were significantly associated with intestinal parasitic infections. Illiterate educational status ( AOR = 2.37 , p = 0.022 ), fishing by bargee ( AOR = 2.43 , p = 0.005 ), fishing ≥4 days per week ( AOR = 2.27 , p = 0.029 ), swimming habit ( AOR = 3.03 , p = 0.030 ), and participation in irrigation ( AOR = 3.09 , p ≤ 0.001 ) predispose fishermen to S. mansoni infection. Conclusion. Intestinal parasites and S. mansoni infections are highly prevalent among fishermen at Lake Tana basin. Low education level and frequent water contact predispose fishermen for intestinal parasites and S. mansoni. Therefore, health education to fishermen on intestinal parasites and S. mansoni infection and regular deworming should be advocated.

Status of intestinal parasitic infections among primary school children in Rivers State, Nigeria, was investigated between January and December 2011. A total of 3,826 stool samples were collected from school children (1,828 males and 1998 females) in 36 primary schools from 13 local government areas of Rivers State. The samples were analyzed using wet saline/iodine and formol ether concentration methods. Of the 3,826 stool samples examined, 1059 (27.66%) were positive for different intestinal parasites, namely,Ascaris lumbricoides(51.78%), hookworm sp. (25.0%),Trichuris trichiura(15.18%),Strongyloides stercoralis(7.14%),Taeniasp. (0.89%), andEnterobius vermicularis(0.01%). The prevalence of the infection was generally higher in males (57.60%) than females (42.40%). The differences were not statistically significant (P>0.05). Among these intestinal parasites,Ascaris lumbricoides, hookworm sp., andTrichuris trichiurawere found in all the 13 local government areas studied whileStrongyloides stercoraliswas found in 12,Taeniasp. in five, andEnterobius vermicularisin only one community in Ahoada Local Government Area. The overall infection rate remains high and would require coordinated deworming of the school children within the state.

Background: Intestinal parasitosis still constitutes one of the major causes of public healthproblems in the world, particularly in developing countries. Nepal is a small, impoverished country prevalent to infectious diseases, including intestinal parasitosis. Poverty, lack of awareness, failure to practice proper hand washing after defecation, practice of open defecation, unsafe drinking water and use of improper toilets are some of the reasons causing of parasitic infections.Aims and Objective: To determine the types of intestinal parasites in stool samples of patients attending to hospital. Materials and Methods: Stools specimens collected in standard stool vial were submitted in microbiology (2006-2010) unit at BP Koirala Institute of Health Sciences hospital (BPKIHS) were examined for intestinal parasites by direct wet mount using normal saline (0.9%) and lugol’s iodine (0.5%).Results: A total of 11,791 stool samples (2928 in 2006, 2238 in 2007, 2151 in 2008, 2344 in 2009 and 2130 in 2010) were submitted to the Parasitology section of Department of Microbiology BPKIHS were included in the analysis. Of these, 675 (5.72%) were positive intestinal protozoa and 289 (2.45%) for intestinal helminths. Giardia intestinalis accounted for the most prevalent parasitic infection (3.34%) followed by Entamoeba histolytica/E. dispar (1.96%) and Hookworm (0.97%). A parasitic infection was observed to be highest among 20-50 years of age group and lowest in the less than 5 years group of subjects.Conclusion: Intestinal parasitosis is a common problem. Amoebiasis, giardiasis and the common intestinal helminthes Ascaris lumbricoides, hookworm, and Trichuris trichiura were prevalent in our settings.Asian Journal of Medical Sciences Vol.8(3) 2017 55-59

SummaryA study screening pet animals (dogs, cats, chinchillas, ferrets, guinea pigs, rabbits, primates, reptiles, and hedgehogs) within Moscow city limits for intestinal parasitic diseases has been conducted over a period of 6 years. According to the study, parasitic infections caused by intestinal protozoa are found in pet animals more frequently than by intestinal helminths. Although dogs and cats exhibit the highest level of diversity of intestinal parasite species, in the group of exotic animals, helminth infection are found much less frequently and parasitic fauna is represented mostly by intestinal protozoa with a high percentage of mixed infection. The most widespread helminth infeсtion of dogs and cats is toxocarosis (respectively 2.5 and 5.7 %) and the most widespread protozoan infection is Giardia sp. (9.8 and 4.6 %). Giardia sp. was found in 47.4 % of chinchillas, Cryptosporidium sp. was more frequently found in ferrets (6.55 %), protozoa from the family Trichomonadida was found in guinea pigs (9 %), Eimeria sp. in rabbits (13.9 %), Acanthocephala in primates (15.7 %), and eggs from the generaOxyurida (59 %), along with protozoa from the family Trichomonadida, in reptiles. Capillaria sp. was most prevalent in hedgehogs (33.4 %). Acanthocephala eggs, as well as protozoa from the Giardia and Entamoeba genera, were more frequently found in primates. Parasites common to animals and humans, which may become a source of infection for the latter under certain conditions, have been identified in pet animals.
