In this study, synanthropic rodents and their helminth parasites were used as sentinels to assess the potential impact of land use on zoonosis. Rats were collected in different ecosystems, namely agricultural, agroforest, and residential areas in the northeastern sub-watersheds of Mount Makiling, Laguna, Philippines. Three (3) species of rats were captured, namely, <jats:italic>Rattus tanezumi, Rattus norvegicus,</jats:italic> and <jats:italic>Rattus exulans</jats:italic>. Of the total 180 rats collected, 92.7 % were found infected with helminth parasites, namely <jats:italic>Hymenolepis diminuta, Hymenolepis nana, Taenia pisiformis,</jats:italic> and <jats:italic>Strobilocercus fasciolaris</jats:italic> (cestodes); <jats:italic>Angiostrongylus cantonensis, Nippostrongylus brasiliensis</jats:italic>, <jats:italic>Strongyloides ratti, Capillaria hepatica, Trichuris muris</jats:italic>, and <jats:italic>Rictularia</jats:italic> sp. (nematodes); and <jats:italic>Echinostoma ilocanum</jats:italic> (trematode). Of these 11 species, nine (9) were considered zoonotic. This study provides important information on the helminth parasites of rats in the northeastern sub-watersheds of Mount Makiling and the potential threat of zoonotic transmission due to increasing land use change and urbanization in the area. Moreover, urbanization can provide favorable eco-epidemiological conditions for rodent-borne pathogens, such as parasites, that are seriously threatening agricultural settings and human settlements in these areas.","PeriodicalId":55061,"journal":{"name":"Helminthologia","volume":"29 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140800382","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}

These provide suggestions as to the number of animals to be sampled and the minimum number of eggs that must be counted to produce statistically meaningful results. One of the considerations for study design is the multiplication factor of the FEC method to be used; methods with lower multiplication factors require fewer animals to be sampled because they are presumed to count more eggs per test. However, multiplication factor is not the sole determinant of the number of eggs counted by any given method, since different techniques use very different sample extraction methodologies that could affect the number of eggs detected beyond just the amount of feces examined. In this light, we compared three commonly used manual FEC methods (mini-FLOTAC, McMaster and Wisconsin) and two automated methods (Imagyst and Parasight All-in-One) with respect to how many equine strongylid and ascarid eggs they counted in the same samples. McMaster and mini-FLOTAC (multiplication factors of 25x and 5x, respectively) produced the most accurate results of the methods tested but mini-FLOTAC counted approximately 5-times more eggs than McMaster. However, Wisconsin and Parasight (multiplication factor = 1x) counted 3-times more ova than mini-FLOTAC, which was less than the 5-fold difference in their multiplication factors. As a result, these tests perform with multiplication factors more akin to 1.6x relative to mini-FLOTAC. Imagyst, due to its unique sample preparation methodology, does not have a traditional multiplication factor but performed similarly to McMaster with respect to egg recovery.","PeriodicalId":55061,"journal":{"name":"Helminthologia","volume":"21 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140800278","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}

Our study characterized two popu lations of <jats:italic>P. coffeae</jats:italic> (associated with Ming aralia and coffee) and compared them with other popu lations from previous studies in Vietnam and other countries in the world. The identification of <jats:italic>P. coffeae</jats:italic> in our study was confirmed by the comprehensive analysis encompassing morphological examination, morphometric data, and molecular characterizations of the <jats:italic>COI</jats:italic> mtDNA and D2D3 of 28S rRNA regions. The cluster and MDS analyses revealed that the two populations of <jats:italic>P. coffeae</jats:italic> from Vietnam are closely related to those from Japan and Indonesia. The D2-D3 sequences of 28S rRNA and <jats:italic>COI</jats:italic> mtDNA regions exhibited high similarity among these populations, indicating a stable genetic profile.

Therefore, nematologists are investing many efforts to develop alternative approaches as proxies applicable in biomonitoring assessment. Recently, an alternative method that combines morpho-functional traits was proposed for detecting assemblage changes of marine nematodes. In view of the promising results, it was tested the same approach to document taxonomic structure changes of soil free-living and plant parasitic nematodes. Specifically, this attempt was carried out using three data sets that include studies from various European regions and different types of ecosystems: forests, grasslands and maize crops. Multivariate statistical analysis revealed that the simple combination of the four traits (i.e., buccal cavity cuticularization occurrence, amphideal fovea size and shape, morphology of the cuticle and pharynx) in a single code number perfectly mirrors the taxonomic structure trends of the nematode assemblage at genus level. Therefore, we predict that similar results can be also obtained by directly encoding nematode specimens with the selected traits and we point to new important advances if this procedure can be coupled with advanced machine learning.","PeriodicalId":55061,"journal":{"name":"Helminthologia","volume":"21 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140800369","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}

The detection of helminth eggs in these samples was performed using sodium hypochlorite (NaOCl) as a diagnostic technique. The study reveals an overall prevalence rate of <jats:italic>T. trichiura</jats:italic> at 0.97 % (35 out of 3600) in the contaminated soil samples from Lahore’s slum areas.

One of the most peculiar characteristics of the Nurse cell of <jats:italic>Trichinella spiralis</jats:italic> (<jats:italic>T. spiralis</jats:italic>) is the complete loss of the contractile capabilities of its derivative striated muscle fiber. The aim of the present study was to clarify the expression of nNOS protein and mRNA in striated muscles during the muscle phase of <jats:italic>T. spiralis</jats:italic> infection in mice. Muscle tissue samples were collected from mice at days 0, 14, 24, and 35 post infection (d.p.i.). The expression of nNOS was investigated by immunohistochemistry, and the expression levels of mRNA of mouse Nitric oxide synthase 1 (<jats:italic>Nos1)</jats:italic> by real-time PCR.

The earthworm, <jats:italic>Eisenia fetida</jats:italic>, is used as a model worm to evaluate the anthelminthic activity of MyE. <jats:italic>Eimeria labbeana</jats:italic>-like oocysts are used as a model protozoan parasite in anticoccidial assays. The sporulation and inhibition (%) of <jats:italic>E. labbeana</jats:italic>-like were assessed by MyE compared to other chemical substances. FT-IR revealed the presence of twelve active compounds. Our results showed that paralysis and death of earthworms at MyE (100 mg/ml) were 7.88 ± 0.37 and 9.24 ± 0.60 min, respectively, which is more potency when compared to mebendazole (reference drug). In all treated worms, microscopic examinations revealed obvious surface architecture abnormality. This study shows that MyE affects oocysts sporulation in a dose-dependent manner.
