Seroprevalence and spatial distribution of Toxoplasma gondii infection in cats, dogs, pigs and equines of the Fernando de Noronha Island, Brazil.
Abstract: Little is known about toxoplasmosis in animals of the Fernando de Noronha Island, Brazil. Therefore, we investigated the prevalence of Toxoplasma gondii infection in the total population of pet cats (n=348), dogs (n=320), pigs (n=27), equines (n=101), as well as a significant portion of the population of feral cats (n=247) of the Island by Indirect Fluorescent Antibody Test. Anti-T. gondii IgG antibodies were found in 71.26%, 54.74%, 48.75%, 51.85% and 22.7%, of the pet and feral cats, dogs, pigs and equines, respectively, demonstrating a high prevalence of T. gondii infection in the wild and domestic animals of the Island. The Kernel intensity estimator showed a correlation between areas with high prevalence of infection in cats and occurrence of infection in the other studied species. We suggest that the island's health authorities should develop initiatives to reduce the population of cats and alert the island's population about the risk of T. gondii infection.

The research article focuses on investigating the prevalence of Toxoplasma gondii infection, a parasitic disease commonly known as Toxoplasmosis, in different species of animals (cats, dogs, pigs, and equines) on the Fernando de Noronha Island, Brazil.
Overview of the Research
This research investigates the occurrence of Toxoplasma gondii infection in animals on the Fernando de Noronha Island, Brazil. The species studied include pet cats, dogs, pigs, equines, and a significant portion of the population of feral cats.
- The objective was to study the prevalence and spatial distribution of Toxoplasma gondii infection.
- The method used for detecting the infection was the Indirect Fluorescent Antibody Test that measures anti-T. gondii IgG antibodies.
Findings of the Study
The results showed that the T. gondii infection was prevalent in animals studied.
- The infection rate was found to be the highest in pet and feral cats at 71.26% and 22.7% respectively.
- The occurrence in dogs stood at 54.74%, while for pigs and equines, the prevalence rates were 48.75% and 51.85% respectively.
- The Kernel intensity estimator, a statistical method used for identifying patterns, showed that in areas where cats had a higher prevalence of the infection, there was an also higher occurrence of infection in other species studied.
Suggested Future Actions
In light of these findings, the research proposed some preventive measures to prevent the spread of the T. gondii infection:
- The Island’s health authorities should develop initiatives to reduce the population of cats, who were found to be the most affected species.
- It was recommended to alert the Island’s population about the risk of T. gondii infection.
