Among the most prevalent protozoan pathogens in children are <em>Entamoeba histolytica, Giardia lamblia,</em> and <em>Cryptosporidium</em> species. However, data on their genetic diversity, co-occurrence, and variability in Kenya remain limited. This study investigated the genetic diversity of <em>G. lamblia, Entamoeba</em> spp.<em>,</em> and <em>Cryptosporidium</em> spp. in children aged 10 years and below in Kiambu County, Kenya. A total of 550 stool samples were analyzed for enteric parasites using formal-ether concentration and Modified Ziehl-Neelsen staining. Genomic DNA was extracted from microscopy-positive samples, and species-specific nested polymerase chain reaction was performed to genotype <em>Entamoeba</em> spp. using the 18S ribosomal RNA gene. For <em>G. lamblia</em> and <em>Cryptosporidium</em> spp., nested PCR and sequencing targeted the <em>βeta-giardin</em>, triose phosphate isomerase, and 60-kDa glycoprotein genes, respectively. Microscopy detected <em>Entamoeba</em> spp. (29.6 %, 163/550), <em>G. lamblia</em> (14.6 %, 80/550), and <em>Cryptosporidium</em> spp. (1.3 %, 7/550). PCR analysis identified <em>E. histolytica</em> (3.3 %, 18/550), <em>E. dispar</em> (3.8 %, 21/550), <em>E. moshkovskii</em> (1.6 %, 9/550), <em>E. coli</em> (13.1 %, 72/550), and <em>E. hartmanni</em> (1.5 %, 8/550). Sequence analysis of the <em>tpi</em> and <em>β-giardin</em> genes identified <em>G. lamblia</em> assemblages A (20/50) and B (30/50). All assemblage A isolates were classified as sub-assemblage AII (20/20), while assemblage B isolates were further subdivided into sub-assemblages BIII (21/30) and BIV (9/30). All <em>Cryptosporidium</em> isolates were identified as <em>C. hominis</em>, with subtypes IbA9G3 (5/6) and IeA11G3T3 (1/6). Microscopy results revealed a significant association between <em>Entamoeba</em> spp. and <em>Cryptosporidium</em> spp. with both age groups and study sites. <em>Entamoeba dispar</em> by PCR and <em>G. lamblia</em> by microscopy showed significant differences between study sites. Additionally, the distribution of <em>G. lamblia</em> assemblages A and B, along with sub-assemblages AII, BIII, and BIV, differed significantly between the study sites. Among these, only sub-assemblage BIV showed a significant association with age groups. The detection of <em>E. histolytica</em> alongside related <em>Entamoeba</em> spp. underscores the importance of molecular diagnostics for accurate amoebiasis management and epidemiological surveillance. Additionally, the identification of <em>G. lamblia</em> sub-assemblages AII, BIII, and BIV, as well as <em>C. hominis</em> subtypes, suggests anthroponotic transmission, emphasizing the need for improved sanitation and public health interventions.</div></div>","PeriodicalId":37941,"journal":{"name":"Food and Waterborne Parasitology","volume":"39 ","pages":"Article e00268"},"PeriodicalIF":2.9,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143948800","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}

However, to accurately assess the risk of <em>Sarcocystis</em> infections in livestock and to develop effective prevention strategies, it is essential to investigate the environmental reservoirs of these parasites. The aim of this study was to identify <em>Sarcocystis</em> species with domestic animals as intermediate hosts by analysing environmental samples (water, hay, and soil) collected from Lithuanian farms and to compare their occurrence across different sample types. In total, 90 environmental samples were collected over 3 years and analysed for the presence of <em>Sarcocystis</em> spp. using nested polymerase chain reactions targeting the <em>cox1</em> gene. The results indicated that livestock are most likely to acquire infections via the ingestion of contaminated water or feed, while soil posed a lower risk of transmission. An assessment of species distribution across sampled farms revealed that the type of livestock raised did not influence the diversity of <em>Sarcocystis</em> spp. Notably, at least six of seven target species (<em>S. arieticanis</em>, <em>S. bertrami</em>, <em>S. bovifelis</em>, <em>S. capracanis</em>, <em>S. cruzi</em>, <em>S. miescheriana</em>, <em>S. tenella</em>) were detected at least once on eight of 10 farms. Additionally, two zoonotic <em>Sarcocystis</em> species, <em>S. hominis</em> and <em>S. suihominis</em>, were identified in environmental samples.

Due to the difficulties in isolating parasites prior to their identification, indirect detection methods are used, mostly relying upon targeted amplification of nucleic acids via PCR and/or qPCR. With the development of high throughput sequencing technologies, an untargeted detection method, shotgun metagenomics, became available. By sequencing the total DNA extracted from a given source, and through bioinformatics analyses of the sequencing reads, shotgun metagenomics allows profiling the entire microbial community therein present, including eukaryotes and, therefore, parasites. In this article, we reviewed the studies that specifically addressed the detection of parasites in food (<em>n</em> = 2) and water matrices (<em>n</em> = 10) by shotgun metagenomics. Most studies focused on wastewater samples and reported the detection of many parasites of human and veterinary importance from various areas of the world, highlighting the potential of shotgun metagenomics to provide important data for parasitic pathogens surveillance. After examining the different analytical workflows employed in these studies, which were not developed for detection of eukaryotes (or parasites), we identified two aspects deserving attention. First, that assignment based on short reads matching ribosomal sequences may generate false positives due to high sequence conservation among eukaryotic organisms. Second, that reassessing the relatively small number of reads of eukaryotic origin by a BLAST search can confirm, or deny, identification of parasitic pathogens.</div></div>","PeriodicalId":37941,"journal":{"name":"Food and Waterborne Parasitology","volume":"39 ","pages":"Article e00265"},"PeriodicalIF":2.9,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143895001","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}

This distorts perception of the geographical occurrence of fasciolosis, particularly in South Africa among other countries. We aimed to determine the infection rates of <em>Fasciola</em> spp. in cattle slaughtered at selected abattoirs in South Africa. A total of 13 abattoirs consisting of 10 high throughput and three low throughput abattoirs across six provinces, were visited to screen for liver fluke infection in slaughtered cattle including tracing of the animals' geographical origin.

Tracing of infected cattle showed that some abattoirs slaughtered cattle originating from other provinces. Forty-nine percent (29/57) of infected cattle had moderate body condition score (BCS) and recorded the highest intensity of fluke infection (&gt;100 flukes per liver). Furthermore, young animals had high infection rates (51 %; 29/57) compared to adults (49 %; 28/57) and females (54 %; 31/57) compared to males (46 %; 26/57).
