The total number of reported cases of intestinal parasites decreased from 4352 for 2011 to 1728 for 2018 and then increased to 2014 cases for 2021. Nearly half of the intestinal parasitic infections were detected among age group of 15 to 44 years. The prevalence of intestinal parasitic infections was higher in males (65.73 %) than females (34.27 %). The prevalence of intestinal parasitic infections was 9 0.47 % for protozoan infections, while the rate of helminth infection was lower (9 .53 %). Entamoeba histolytica/dispar were the most common parasite (60.92 %) followed by Giardia lamblia (29.54 %) and Enterobius vermicularis (8.56 %). Prevalence of infection with intestinal parasites was lowest in March and highest in February.Conclusion: In spite of that intestinal parasitic infection rates appear to be decreasing, intestinal parasitic infection remains an important health problem in the province. Therefore, there is still a need for prevention efforts in the community.","PeriodicalId":55061,"journal":{"name":"Helminthologia","volume":"61 3","pages":"214-223"},"PeriodicalIF":1.1,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11637541/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142830953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to global warming, it is expected that Aedes aegypti will be able to survive at higher latitudes, increasing the number of people at risk. Therefore, it is crucial to develop control strategies for the mosquito to prevent its environmental impact. The objective of this paper was to determine the concentration of entomopathogenic nematode (EPN) Steinernema carpocapsae that produces the highest percentage mortality of Ae. aegypti larvae under normal environmental conditions in Yucatán (6.9 - 8.7 mg/l; temperature 25.9 - 31.5°C; pH 7.20 - 8.10). The S. carpocapsae mode of action consists of Xenorhabdus nematophila bacterial release in the haemocele insect, which produces septicaemia and consequently kills the mosquito larvae 24 - 48 h after intake. As for the methodology, a commercial EPN strain was used for experimental infection. The experimental design was a 70-h static bioassay that exposed 10 mosquito larvae per experimental unit (400-ml flask and five replicates per treatment) to four nematode concentrations (1250, 2500, 3125 and 3750 nematodes per ml) plus controls. The best treatment was with 1250 nematodes/ml, which caused 54 % mortality with respect to controls after 70 h (one-way ANOVA; F 5.72, 0.05; p < 0.04). We concluded that S. carpocapsae is a promising biological control tool for killing Ae. aegypti larvae at an experimental level. However, it is still necessary to determine its performance at higher volume scales in real-life conditions.","PeriodicalId":55061,"journal":{"name":"Helminthologia","volume":"61 3","pages":"254-262"},"PeriodicalIF":1.2,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12288946/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144709971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It holds significance for public health by identifying potential zoonotic risks. We aimed to describe the occurrence of gastrointestinal parasites in captive wild birds from a Conservation Institute in Brazilian Cerrado biome. Fresh fecal samples were collected from 17 captive wild birds (Anodorhynchus hyacinthinus, Ara ararauna, Ara chloropterus, Ara macao, Megascops choliba, Pteroglossus castanotis, Ramphastos dicolorus, Ramphastos tucanus and Strix huhula) at a Conservation Institution in Mineiros, state of Goiás. The samples were processed for Willis’ simple flotation and Hoffman’s spontaneous sedimentation examinations to identify parasitic forms of gastrointestinal endoparasites. Macaw aviary birds (Ar. ararauna, Ar. chloropterus and Ar. macao) showed higher positivity, with all six fecal samples positive for helminths or protozoa. In contrast, captive toucans showed only two positive results (P. castanotis and R. dicolorus). An. hyacinthinus showed Ascarididae, Capillarinae and Trematoda eggs; whereas S. huhula had Ascarididae eggs. Regular parasitological examinations are essential for the timely detection and treatment of gastrointestinal infections in captive birds, thereby enhancing overall bird management.","PeriodicalId":55061,"journal":{"name":"Helminthologia","volume":"20 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141741443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study identified monogenean parasites in the twobar seabream, Acanthopagrus bifasciatus (Sparidae), inhabited the Arabian Gulf (Saudi Arabia). Following that, forty A. bifasciatus fish samples were visually examined for monogeneans. Parasite species were collected from the gills and then analyzed morphometrically, morphologically, and molecularly using the partial regions of the large subunit of ribosomal RNA (28S rRNA) and mitochondrial cytochrome C oxidase subunit I (COI) genes. Fish species were also identified using a DNA barcoding approach based on the COI gene. The monogenean species of Diclidophora merlangi (Diclidophoridae) were found in 45% of the fish species studied. The generic features of the Diclidophora genus distinguish this species. This species discriminated itself from congeners by having a muscular bulb with 17 grooved and recurved hooks, 218±10 (184–267) post-ovarian testes, and four pairs of pedunculated clamps of relative sizes. Partial 28S rRNA sequencing from monogeneans revealed that they grouped with members of the genus Diclidophora, forming a monophyletic group that supported the morphological descriptions. Molecular identification revealed that D. merlangi has a unique barcode made up of a COI sequence. The host identity was established as A. bifasciatus based on the COI gene sequences. Furthermore, a molecular phylogenetic study was performed to determine the phylogenetic affinity of parasite species and fish hosts. This study on Diclidophora species is considered the first record of this genus in the examined area.","PeriodicalId":55061,"journal":{"name":"Helminthologia","volume":"124 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141741445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
