Trichinella spiralis and T. britovi in North-Eastern Romania: A Six-Year Retrospective Multicentric Survey.

Abstract: The genus includes species with a wide geographical spread that cause pathology in humans and animals. In this context, an epidemiological study of infection was carried out in the northeastern part of Romania to investigate for the first time the prevalence of this infection in pigs, horses, wild boars and bears, the geographical distribution of species and the natural reservoir of infection. Between 2010 and 2015, a total of 166,270 animals were examined by the method of artificial digestion, in order to calculate the annual and general prevalence of infection, according to the host and the species involved, the Pearson correlation coefficient (r), trendline and geographical distribution of species of the genus . Taxonomic framing was performed by the multiplex PCR method. The overall prevalence of infection in animals was 0.188%. Within the host species, the prevalence varied as follows: in pigs 0.096%, horses 0.021%, wild boar 1.46% and bears 36.76%. The geographical distribution showed that was dominant, occupying the entire northeastern part of Romania, being identified in pigs, horses, wild boars and bears. occupied five mountain counties, being identified only in wild boars and bears. These results validate the presence of and in domestic and game animals in the northeastern part of Romania.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

This research article evaluated the spread of the Trichinella spiralis and T. britovi parasites in North-Eastern Romania amongst various animal species like pigs, horses, wild boars and bears, and their ecological distribution. Between 2010 to 2015, a total of 166,270 animals were examined revealing an overall infection prevalence of 0.188%. T. spiralis was predominant, found in all examined animal species and across the region, while T. britovi was more geographically limited, found in wild boars and bears in mountainous areas.

Methodology

  • The researchers conducted a six-year multicentric survey from 2010 to 2015, examining a total of 166,270 animals using the artificial digestion method.
  • The animals investigated included pigs, horses, wild boars, and bears from north-eastern Romania.
  • The annual and overall Trichinella infection prevalence was calculated based on host and Trichinella species.
  • Pearson correlation coefficient (r), trendline, and geographical distribution analyses were used to track the spread of Trichinella species.
  • Trichinella species were identified through taxonomic framing performed by the multiplex PCR method.

Findings

  • Overall Trichinella infection prevalence in the animals studied was 0.188%.
  • The prevalence varied among host species: in pigs it was 0.096%, horses 0.021%, wild boars 1.46%, and bears 36.76%.
  • Trichinella spiralis parasite was found to be dominant in the north-eastern part of Romania, identified in all host species examined.
  • Trichinella britovi parasite was geographically limited to five mountain counties, identified only in wild boars and bears.

Implications

  • The survey validated the presence of Trichinella spiralis and T. britovi in domestic and game animals in north-eastern Romania, which can have a direct impact on public health as these parasites can cause diseases when transmitted to humans.
  • These findings highlight the need for continued animal health surveillance and appropriate control measures to prevent the spread of these parasites further.
