The role of Toxocara cati as a zoonosis is reviewed. It is suggested that, despite case histories of human infection in the literature, historical factors have led to T. cati being under-recognized as a zoonosis, particularly when compared with the prominence given to Toxocara canis in dogs. Differentiation of the two infections remains challenging even today. It is recommended that further work be conducted to facilitate differentiation so that the importance of T. cati as a zoonosis can be clearly defined.

Article Synopsis
- The study focused on detecting parasite DNA in soil from 34 houses in rural Yucatan, Mexico, using a specialized technique to highlight environmental reservoirs for human parasites.
- Results showed that 65% of the houses had at least one type of parasite, with Acanthamoeba spp. being the most common, while some houses even had multiple parasites detected in a single sample.
- This research emphasizes the significance of soil as a habitat for various parasites, which can pose health risks to rural communities, marking an important finding in the field of environmental health.

A case of polyparasitism in an 8-year-old female cat from Southern Brazil is reported. Among the described clinical signs, both gurltiosis and lagochilascariasis are of rare occurrence, being categorized as neglected diseases. The diagnosis of feline crural parasitic paraplegia was established through clinical signs, necropsy lesion observations, and the presence of Gurltia paralysans in histological sections of the spinal cord.

Background: For several decades, the European wildcat (Felis silvestris) has gradually been returning to the forests of Germany, mainly in the central and southwestern regions. To increase the knowledge about this threatened species, the endoparasite status of dead found specimens from Germany was surveyed.
Methods: A total of 118 wildcats were examined for endoparasites in peritoneal organs and skeletal muscles.
Toxocariasis is a common zoonotic parasitic disease, primarily caused by the larvae of or . Humans become infected through accidental ingestion of infective eggs in soil contaminated with feces of infected animals, or by consuming undercooked meat from paratenic hosts harboring larvae. This cross-sectional study aimed to evaluate the seroprevalence of spp.

Article Synopsis
- Toxocara canis and Toxocara cati are parasitic worms found globally, particularly posing risks to children through their eggs in the environment, highlighting the need for effective diagnostic methods for detection.
- This study compared different detection techniques including a new sequential sieving protocol and a high-throughput qPCR method, evaluating their efficiency on cat and dog faecal samples.
- Results indicated that the new sieving method was superior in sensitivity for egg detection, while mechanical lysis of DNA samples outperformed enzymatic lysis, and both DNA detection and microscopy methods showed comparable results with newer techniques being cost-effective.
