Opis:
B6C3F₁ mice were infected with 200 or 500 larvae of Trichinella spiralis per mouse and pulmonary NK cell-mediated clearance of semisyngeneic tumour cells was determined in vivo on days 10, 20, 30, and 60 after the infection. Cytotoxic activity of NK cells in the lungs was substantially elevated on days 20 and 30 after challenge with both „doses" of the parasite. At the same time large granular lymphocytes (LGLs) as well as cells expressing surface asialo-GM₁ molecules were isolated in elevated numbers from spleens of the infected as opposed to the normal mice. Expression of other markers of differentiation, such as THy 1, CD4, and CD8 was also enhanced on splenocytes isolated from the infected mice on day 30 but not 20 after administration of the larvae. The present results indicate that NK cell-mediated activity in vivo is stimulated above the baseline level during migration and early muscle phases of the infection with T. spiralis in mice. The possible impact of this effect upon the course of trichinellosis as well as upon the growth of tumours in the infected host is discussed.

Opis:
The aim of this study was to present the current situation of trichinellosis, basing on the results of examination of the tissues of animals hunted in Poland. Investigation was carried out from 1st January to 30th June 2022 in the Department of Parasitology and Parasitic Diseases of National Veterinary Research Institute in Poland. Samples were collected out of 103 wild boars (Sus scrofa) and one wolf (Canis lupus), originating from 14 voivodeships. The study of wild boars muscle tissues revealed 89 positive samples, including 60 T. spiralis, 21 T. britovi, two T. pseudospiralis, and five mixed invasions with T. spiralis and T. britovi. In one case no amplification products were obtained. T. britovi was also found in the sample of wolf muscle tissue. This study emphasize the fact that trichinellosis in hunting animals is still a zoonotic threat, and should be closely monitored.

Opis:
ELISA can be used to measure produced antibodies or Trichinella spp. antigens in the samples. They are detected with antibodies linked to an enzyme that reacts with a substrate and generate a colour reaction. The optical density (OD) of the reaction is measured spectrophotometrically. ELISA assays can be done in several different procedures called „direct”, "indirect", "sandwich", and "competition" ELISA. Since the 1970s, the studies have been done on improving or replacing direct methods of Trichinella diagnosis with serological methods based on the ELISA. When somatic antigens of L1 T. spiralis were used, the specificity of the ELISA was poor due to a high probability of cross-reactions with other pathogens. During the 1980s the specificity of the ELISA was improved by excretory-secretory (E/S) antigens obtained during Trichinella muscle larvae incubation in vitro. Recently a synthetic glycan antigen has been developed and the increasing of ELISA specificity and sensitivity was noticed. The sensitivity of the ELISA using an E/S antigen ranging from 93.1 to 99.2% but the specificity from 90.6 to 99.4%. The ELISA method is relatively simple to apply, reliable, readily standardized and provides an acceptable balance of sensitivity and specificity. But all modified procedures should be validated. In Poland, the studies on the usefulness of ELISA for antibodies detection against T. spiralis in pigs and wild animals are limited. Own ELISA procedure was prepared in Pathophysiology Lab. in W. Stefański Institute of Parasitology of PAS. ELISA was used to examine IgG level against L1 T. spiralis in pigs and wild boars serum samples. Of 1474 pig samples, only 12 were positive. Of 1880 wild boar samples only 14 were positive. The results of this study are comparable with performance obtained using commercial sets. The results showed the usefulness of ELISA for T. spiralis diagnosis in pigs and wild boars and confirmed the possibility of use the ELISA test for application in the slaughterhouse.

Opis:
Backround. Since Owen first described Trichinella as a human patogen in 1835, the number of organisms comprising this genus has grown dramatically. This etiological agent of human trichinellosis shows worldwide distribution in domestic and/or sylvatic animals. Material and method. The aim of the presented paper was to determine the distribution of Trichinella species in wild animals such as red foxes, wolves, wild boars, and domestic pigs in Poland. Muscle samples from diaphragm and forelegs were collected from animals killed by hunters. Muscle larvae were recovered from the muscle after artificial digestion and identified at the species level by RAPD, PCR-RPLF and multiplex PCR. Results. Of 75 nematode isolates from red foxes: (Vulpes vulpes), 50 resulted as T. britovi, 6 T. spiralis, 6 were mixed infections of these two species. Fifteen Trichinella isolates remained unidentified. Of 97 nematode isolates from wild boars (Sus scrofa), 21 resulted as T. britovi, 69 T. spiralis, 2 were mixed infections of these two species. Five Trichinella isolates remained unidentified. Of 6 examined wolves (Canis lupus) killed in the Bieszczady region, 3 animals were positive against T. britovi. Of 6 examined raccon dogs (Nyctereutes procyonoides) from Pomorskie region, 2 animals were positive against T. spiralis. Of 21 nematode isolates from domestic pigs, 1 resulted as T. britovi and 21 as T. spiralis. Up to date, two Trichinella species are detected as the etiological agents of epidemiology among domestic and wildlife animal in Poland: T. britovi is the dominant species in red foxes and T. spiralis is the dominant species in wild boars and domestic pigs.
