Nematodes of the genus are important pathogens of humans and animals. This study aimed to enhance the genomic and transcriptomic resources for (non-encapsulated phenotype) and (encapsulated phenotype) and to explore transcriptional profiles. First, we improved the assemblies of the genomes of (code ISS13) and (code ISS534), achieving genome sizes of 56.

Background: Worms of the nematode genus Trichinella are zoonotic pathogens with a worldwide distribution. The first report of Trichinella on the Mediterranean island of Sardinia was for Trichinella britovi, one of the four species of this genus circulating in Europe, which was identified in 2005 following an outbreak of trichinellosis in humans due to the consumption of pork from pigs reared in the wild. Since then, T.

The main reservoir hosts of nematodes of the genus are wild carnivores, although most human infections are caused by the consumption of pork. This group of zoonotic parasites completes the entire natural life cycle within the host organism. However, there is an important phase of the cycle that has only been highlighted in recent years and which concerns the permanence of the infecting larvae in the striated muscles of the host carcasses waiting to be ingested by a new host.

Article Synopsis
  • Trichinella spp. infections were studied in bobcats from 41 counties in Oklahoma, revealing a 5.9% infection rate among the 306 bobcats examined.
  • Infected bobcats were found in 10 out of the 41 counties, but no significant prevalence differences were observed across the counties.
  • The study identified T. murrelli as the primary species, with one case of T. pseudospiralis reported, marking the first discovery of this species in bobcats and Oklahoma.

Background: Domesticated pigs are the main source of Trichinella sp. infections for humans, particularly when reared in backyards or free-ranging. In temperate areas of southern Europe, most pigs are farmed under controlled housing conditions, but sows and sometimes fattening pigs have access to outdoors to improve animal welfare.

Article Synopsis
  • Trichinella spiralis is a major foodborne parasite responsible for trichinellosis outbreaks, particularly in pig farms and wild boars, and identifying its sources is crucial for controlling its spread.
  • Traditional molecular methods fall short in distinguishing infection sources due to limited genetic variation in T. spiralis in Europe, but microsatellite markers have been effective for related parasites with more genetic diversity.
  • This study used microsatellite markers to analyze T. spiralis larvae from two pig farm outbreaks and ten wild boars, revealing uniform parasite populations at each farm, a genetic link between the outbreaks, and greater genetic variation in wild boar parasites.

  • A non-encapsulated species within its genus has been identified as the first to infect mammals and birds, with the first detection in a wolf from Central Italy in October 2020.
  • This species was previously found in various animals in Italy, including a red fox, three bird species, and five wild boars, and is linked to a human outbreak of trichinellosis in 2015.
  • The rarity of this nematode in carnivorous mammals compared to its encapsulated counterparts raises questions about the role of these carnivores as potential reservoirs for the parasite.

Laboratory tools for diagnosing taeniosis/cysticercosis in non-endemic countries are available; however, there is little data on their performance. To provide information on the sensitivity, specificity, and reproducibility of these tools, inter-laboratory studies were organized within the EU COST-Action CYSTINET (TD1302). Two serological and one coprological Ring Trials (RTs) were organized to test a panel of human-derived sera and stool samples using assays routinely conducted by the participating laboratories to detect spp.

Human trichinellosis can be diagnosed by a combination of medical history, clinical presentation, and laboratory findings, and through detection of anti-Trichinella IgG in the patient's sera. ELISA using excretory-secretory (E/S) antigens of Trichinella spiralis larvae is currently the most used assay to detect Trichinella spp. antibodies.

Trichinella spiralis has historically been deemed "the pig parasite" owing to its initial classification within a monospecific genus. However, in recent years, the genus has expanded to include 10 distinct species and at least 3 different genotypes whose taxonomic status remains unstipulated. In contrast to T.

Trichinellosis is a zoonotic disease due to the ingestion of raw or undercooked meat from animals infected with the larvae of nematodes belonging to the genus Trichinella. In January-February 2015, an outbreak of trichinellosis occurred in Genoa, Northern Italy. The epidemiological link was traced back to a dinner served at an agritourism farm on 31 December 2014, where a majority of the 52 guests had consumed the 'beef' steak tartare.

Background: Domesticated and wild swine play an important role as reservoir hosts of Trichinella spp. and a source of infection for humans. Little is known about the survival of Trichinella larvae in muscles and the duration of anti-Trichinella antibodies in pigs with long-lasting infections.

Bulgaria is one of European countries where trichinellosis continues to be regularly diagnosed and registered. The clinical and epidemiological features of 72 cases of trichinellosis associated with five outbreaks caused by Trichinella spiralis and Trichinella britovi between 2009 and 2011, are described. At hospital admission, patients were often initially treated with antibiotics, without any improvement.

Being able to identify the species or genotype of is of paramount importance not only for epidemiological studies but to better ascertain the source of outbreaks that still occur worldwide. This has become more critical in recent years given the increase in imported meat products and the relationship that wild animals play in the domestic and sylvatic transmission cycles. In contrast to a time when the genus was considered monospecific, research in recent years has revealed that the genus consists of 9 species and at least 3 additional genotypes which have yet to be named.

Domestic and wild animals which consume meat are at risk of becoming infected with and therefore may pose a public health risk. Among domestic livestock, pigs are most commonly associated with infection, but human outbreaks have also resulted from consumption of horsemeat, wild boar, bear, walrus and other wild animals. For animals that are not produced under controlled management conditions and for wild animals, specific steps should be taken to prevent human exposure to .

The scientific basis that led to the development of a multispecies concept within the Trichinella genus originated in the 1950s, when scientists began reporting an increasing number of host-specific peculiarities among different geographic isolates. This led to speculation that important geographic variability existed within Trichinella spiralis, the only species in the genus at that time. Comparative infection results sparked great interest among investigators and led to similar studies using various geographic isolates of the parasite.

  • Human trichinellosis is an infection caused by the Trichinella worms, and in Italy, reporting these cases is mandatory, but annual incidence data is lacking.
  • A study from 2005 to 2016 found that 70.6% of hospital records incorrectly reported trichinellosis, highlighting significant data inaccuracies.
  • The research suggests creating a national registry to improve surveillance and identification of cases, which could reduce unnecessary treatments and economic costs to Italy’s healthcare system.

This study identified helminth species of wild boar (Sus scrofa) originating from northeastern and northwestern regions of Tunisia using 297 lungs, 297 livers, 264 intestinal tracts, 120 samples of muscle tissue (tongue, masseter, diaphragm, inter-costal) and 232 faecal samples derived from a total of 591 animals. Host gender was registered for the lung and liver wild boar group, which included 163 males and 134 females. All animals, excluding those used to retrieve muscular samples, were classified into three age classes, <2 (n = 212), 2-3 (n = 208) and ⩾4 years old (n = 141).
