Hookworm infections remain a significant public health concern in tropical and subtropical regions, including Thailand. This study investigated the species and genetic diversity of hookworm infections in domestic dogs from northeastern Thailand. The molecular analysis focused on amplifying and sequencing specific regions of ribosomal RNA genes (ITS1-5.8S-ITS2 region) and the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene in hookworm larvae recovered from 21 domestic dog stool samples. Among 21 larvae (one larva per infected dog) analyzed, 14 had sequences identical to Ancylostoma caninum, and 7 showed sequences almost identical to Ancylostoma ceylanicum. Phylogenetic analysis of cox1 sequences placed A. caninum and A. ceylanicum in separate clades. The median-joining network of A. caninum cox1 sequences from Thailand showed high haplotype diversity and belonged to the same cluster as sequences from Australia while forming separate clusters from those of A. caninum samples from the USA. The available published A. ceylanicum cox1 sequences (n = 33), in combination with seven sequences in the present study, represented 15 haplotypes distributed among three clusters. Interestingly, A. ceylanicum sequences from dogs and humans shared the same haplotypes. These findings are crucial for recognizing the potential for zoonotic transmission, highlighting the necessity for targeted control measures, and increasing awareness among pet owners and healthcare professionals to mitigate the risk of hookworm transmission to humans.

Soil-transmitted helminths (STH) include species responsible for hookworm disease, ascariasis, and trichuriasis. In the United States, STH infections have been greatly reduced with anthelmintic medications and improved hygiene and sanitation, however, cases still regularly occur, but limited epidemiological data exist. We investigated the occurrence of STH infections using big-data analytics of inpatient medical discharge records (1998-2020).

Background: Routine epidemiological data are essential for monitoring the effectiveness of preventive chemotherapy (PC), optimizing resource allocation, and addressing the evolving needs in the elimination of soil-transmitted helminthiasis (STH). This study assesses the prevalence, intensity, and associated risk factors of STH following five rounds of albendazole-based PC in three implementation units (IUs) in Ondo State, Nigeria.

Methodology: Fresh stool samples were collected from 2,093 children aged 5-14 years across 45 systematically selected schools in three IUs: Ese-Odo, Irele, and Ile-Oluji.

Background: Intestinal parasitic infections are a significant public health concern, especially among food handlers, who can transmit these infections to the public through food preparation and handling. This systematic review and meta-analysis aimed to determine the pooled prevalence and associated factors of intestinal parasitic infections among food handlers in the East African region.

Methods: A systematic review and meta-analysis on intestinal parasitic infections among food handlers involved a comprehensive search across various databases, including Scopus, PubMed, ScienceDirect, Google Scholar, and the institution's library registers.

BACKGROUND Ancylostoma caninum is a soil-borne, soil-transmitted helminth with infective larvae and produces cutaneous larva migrans in humans. The objective of this study was to confirm the presence of A. caninum in domestic dogs from the urban-marginal and rural sectors of the Ecuadorian coast through morphometry, culture, and molecular techniques.

Background: Hookworm infection is a common problem among schoolchildren and mothers in tropical and subtropical countries, causing cognitive impairment, growth retardation in children and anaemia, low birth weight, preterm birth, and intrauterine growth delay in susceptible mothers. Since schoolchildren generally have a higher prevalence due to behavioral and hygiene-related factors, our systematic review and meta-analysis aimed to determine the prevalence and risk factors for Hookworm infection among schoolchildren in Ethiopia.

Methods: Relevant studies were retrieved from several search databases.
