AI Article Synopsis
- Ancylostoma ceylanicum is a hookworm species that can mature in the human intestine and is known to infect humans in neighboring countries, but has not been reported in Vietnam until now.
- A study conducted in Long An Province collected 526 fecal samples, revealing an overall human hookworm infection rate of 16.2%.
- The presence of larvae confirmed the existence of two hookworm species, with single infections of Necator americanus and A. ceylanicum, as well as mixed infections occurring in the samples.
Article Abstract
Ancylostoma ceylanicum is recognized as the only zoonotic hookworm species that is able to mature into adult stage in the human intestine. While human infections caused by this hookworm species have been reported from neighboring countries and this hookworm is prevalent in dogs in Vietnam, human infection has never been reported in Vietnam. The present study, therefore, aimed to identify human infections with A. ceylanicum in Vietnam. A total of 526 fecal samples from the residents in Long An Province were collected and the presence of hookworm eggs was detected by the Kato-Katz method. The results indicated that the overall prevalence of human hookworm infection was 85/526 (16.2%). After filter paper culture, 3rd stage larvae were successfully obtained from 48 egg-positive samples. The larvae were identified for their species using semi-nested PCR-RLFP on the cox1 gene. As a result, two hookworm species were confirmed; single species infections with Necator americanus or A. ceylanicum, and mixed infections with both species were found in 47.9%, 31.3%, and 20.8% of the samples, respectively.

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.

Canine hookworm (Ancylostoma caninum), a gastrointestinal nematode of domestic dogs, principally infects the small intestine of dogs and has the potential to cause zoonotic disease. In greyhounds and pet dogs in the USA, A. caninum has been shown to be resistant to multiple anthelmintics.

Introduction: Increasing urbanization has particularly affected rivers and their outer edges in cities, including Kathmandu Valley, which encompasses Lalitpur, the nation's third-largest city. This study aims to conduct a parasitological survey to investigate the occurrence of zoonotic intestinal protozoa and helminths along the Karmanasa River bank in central Nepal.
Methods: Faecal samples from openly defaecating animals were collected via non-invasive techniques, and coproscopy was carried out using direct wet mount, concentration and acid-fast staining methods to ensure reliable findings.

Infections with hookworms ( and ) remain a major public health problem in low- and middle-income countries. However, the information about the distribution of each species is inaccurate in many countries since their traditional diagnosis is based only on the identification of eggs in stool under a microscope. We aimed to identify the prevalence of hookworm species using morphological stools to identify L3 larvae to gain insights into the distribution of both species in five regions of Cameroon.

There is a growing number of reports on the occurrence of benzimidazole resistance-associated single nucleotide polymorphisms (SNPs) in the β-tubulin isotype 1 gene of various helminths of veterinary, and public health concerns. However, a comprehensive analysis of their occurrence, and their contributions to conferring benzimidazole resistance among hookworms has yet to be done. The objectives of this systematic review are to summarize and synthesize peer-reviewed evidence on the occurrence of these resistance-associated mutations in hookworms, document their geographical distribution, and assess their contributions to conferring phenotypic resistance.
