Stool samples were collected from 2592 outpatients with amoebiasis symptoms of both sexes and different ages (≤ l to 60). Also, 107 stool samples were taken randomly from asymptomatic individuals and examined microscopically to detect infection with Entamoeba spp. the positive specimens were used for molecular analysis with positive symptomatic samples targeting the 18S rRNA gene by nested PCR. Microscopically 21.68% (562/2592) were positive, for Entamoeba spp. Males showed highest infection rate than females (67.43% vs 32.56%). Ages from 1-10 years showed the highest rate (54.09%), and urban inhabitant had somewhat a higher rate than rural one (58.54% vs 41.45%) which was statistically non-significant(P>0.05). Among asymptomatic individuals, 57% (61/107) were positive for Entamoeba spp. Nested PCR analysis yielded 73% positive samples for Entamoeba spp. with a fragment size of 897 bp. Three fragment sizes were produced, for E. histolytica, E. dispar and E. moshkovskii which were 439, 174 and 553 bps, respectively. Single infection occurred with, E. histolytica in 46%, of symptomatic and 6% of asymptomatic cases, E. dispar in 38% of asymptomatic and 10% of symptomatic cases, E. moshkovskii, reported at very low rate among both groups.","PeriodicalId":7987,"journal":{"name":"Annals of parasitology","volume":"70 2","pages":"91-101"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141995116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The quantity of chlamydospores of D. flagrans required for the reduction of third-stage larvae (L3) of sheep gastrointestinal nematodes (GIN) is largely unknown, and a matter of discussion. The aim of this experiment was to determine in vitro the nematophagous activity of four different concentrations of D. flagrans (1000, 3000, 6250, or 11000 chlamydospores/ml) in the presence of varying numbers of GIN third-stage larvae (L3) (500, 1000, 1500). Additionally, the study sought to evaluate the efficacy of this fungus on Haemonchus contortus, Teladorsagia circumcincta, Trichostrongylus colubriformis and Chabertia ovina. The results showed that as fungal concentrations increased, so did the larval reduction of third-stage infective larvae in each test. L3s number was not a determining factor in the efficacy against GIN. The comparison between various concentrations of chlamydospores revealed significant differences, particularly between 1000 and 11000 chlamydospores (P≤0.05). Regarding the larval reduction of the GIN species considered, D. flagrans demonstrated the same effectiveness across all species tested. The results of the current study confirm the efficacy and underscore the importance of D. flagrans as an alternative for controlling of GIN.","PeriodicalId":7987,"journal":{"name":"Annals of parasitology","volume":"70 2","pages":"113-118"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141995115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of the two species associated with the human host, Demodex folliculorum is much more commonly detected and occurs more abundantly in hair follicles and Zeiss glands. Demodex brevis, on the other hand, is mainly associated with the sebaceous and meibomian glands, all over the body. The infestation is usually chronic, and the troublesome ocular and skin symptoms often make it difficult for patients to function in both a social and professional context. Despite this, diagnostics for Demodex spp. are still not routinely performed during ophthalmological and dermatological examinations. We aimed to compare preparations of eyebrow hair, eyelashes, and skin scrapings, and to investigate the correlation with false negative results in the laboratory diagnosis of demodicosis. Direct microscopic examination was applied on 100 patients (81 women and 19 men). The most common ocular and skin symptoms reported by the study participants were eyelid itching and erythema, respectively. Significant differences were found between infested and uninfested patients with regard to the following symptoms: eyelid itching which was more common in infested patients (35.8%) (p = 0.0343) and chalazion occurring only in infested patients (13.2%) (p = 0.0285). The collection of diagnostic material from more than one site e.g. nasolabial folds, eyebrow hairs or eyelashes has a significant effect on the test result. Taking a single type of a sample from a single face zone can lead to false negative results.","PeriodicalId":7987,"journal":{"name":"Annals of parasitology","volume":"70 4","pages":"173-180"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143963222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study is to conduct the 3rd research period during 2015-2019 the helminth fauna of these animals living on the drainage channel banks of model reclamation systems in Brest Polesie (south-western part of Belarus), to establish the species composition of helminths and the animal infection by these, and to compare the data obtained with previous research periods. 4,000 trap-days were worked out. 151 specimens of shrews of 4 species and 510 small rodents of 8 species were caught. Animals were examined by the method of complete helminthological dissections. Their numbers were 3.78 and 12.75 individuals per 100 trap-days, and helminth infection was 94.7% and 65.9%, respectively. 66 helminth species were found in animals. The dominant helminth species in infection have been identified. The trematode Prosolecithus danubica Tkach et Bray, 1995 (definitive host: common shrew), the acanthocephalans Centhrorhynchus aluconis (Müller, 1780) (larval host: lesser shrew) and Moniliformis moniliformis (Bremser, 1811) (definitive host: striped field mouse) are new species of helminths for Belarus. New hosts in Belarus have been found for 6 helminth species. Shrews and small rodents are involved in the life cycles of bird, non-ruminant artiodactyl and carnivorous mammal helminths. Nine helminth species have significance for medicine and 7 species for veterinary science.
