“…In the USA, Trichinella spiralis larvae were identified in wild boar meat samples [49]. Mixed infection by T. spiralis and T. britovi in a wild boar was reported in Spain [50] and mixed infection by T. spiralis and T. pseudospiralis in wild boars in Germany [51]. The monitoring plan revealed the sporadic presence of Trichinella britovi in the wild boar population in two municipalities in the Piacenza province (Figure 1).…”

In recent years, the growth of wild ungulates has increased the focus on their health monitoring. In particular, the health status of wild boars is relevant for the economic impact on the pig industry. The Emilia-Romagna region activated a wildlife monitoring plan to better evaluate the health status of the wild boar population. Between 2011 and 2021, samples of found dead and hunted wild boar have been examined for trichinellosis, tuberculosis, brucellosis, african swine fever, classical swine fever, Aujeszky’s disease, swine vesicular disease, and swine influenza A. Trichinella britovi was identified in 0.001% of the examined wild boars; neither M. bovis nor M. tuberculosis were found in M. tuberculosis complex positive samples; 2.3% were positive for Brucella suis; 29.4% of the sera were positive for Aujeszky’s disease virus; and 0.9% of the samples were positive for swine influenza A virus. With an uncertain population estimate, the number of animals tested, the number of positives, and the sampling method do not allow us to make many inferences but suggest the need to implement and strengthen the existing surveillance activity, as it seems to be the only viable alternative for safeguarding animal and human health.

“…The genus Trichinella is divided into an encapsulated clade and a non-encapsulated clade, referring to the collagen capsule that surrounds the larvae of some species in the host muscle. Currently, the genus Trichinella is classified into eight species ( T. spiralis , T. nativa , T. britovi , T. pseudospiralis , T. murrelli , T. nelsoni , T. papuae and T. zimbabwensis ) and three unclassified genotypes ( Trichinella T6, Trichinella T8 and Trichinella T9) (Pozio & Zarlenga, 2005; Rodriguez et al , 2008). All known Trichinella species are morphologically indistinguishable except for T. pseudospiralis , which is smaller in size than other species.…”

The first occurrence of Trichinella murrelli in wild boar in Iran and a review of Iranian trichinellosis

Trichinella larvae isolated from the thigh muscle of a wild boar, Sus scrofa, captured from Gilan Province, northern Iran, was processed for DNA analysis. Polymerase chain reaction (PCR) for amplification of the 5S rDNA fragment demonstrated a 700 bp band on agarose gel. Analysis of DNA sequencing by BLAST confirmed the isolate as T. murrelli. This report constitutes the first recorded occurrence of T. murrelli in Asia, and also the first occurrence in a wild boar host.

Wild boars (Sus scrofa) are indigenous in many countries in the world. These free-living swine are known reservoirs for a number of viruses, bacteria and parasites that are transmissible to domestic animals and humans. Changes of human habitation to suburban areas, increased use of lands for agricultural purposes, increased hunting activities and consumption of wild boar meat have increased the chances of exposure of wild boars to domestic animals and humans. Wild boars can act as reservoirs for many important infectious diseases in domestic animals, such as classical swine fever, brucellosis and trichinellosis, and in humans, diseases such as hepatitis E, tuberculosis, leptospirosis and trichinellosis. For examples, wild boars are reservoirs for hepatitis E virus, and cluster cases of hepatitis E have been reported in Japan of humans who consumed wild boar meat. In Canada, an outbreak of trichinellosis was linked to the consumption of wild boar meat. The incidence of tuberculosis owing to Mycobacterium bovis has increased in wild boars, thus posing a potential concern for infections in livestock and humans. It has also been documented that six hunters contracted Brucella suis infections from wild swine in Florida. This article discusses the prevalence and risk of infectious agents in wild boars and their potential transmission to livestock and humans.
