“…Jongwutiwes et al (1998) reported elevated levels of CPK, LDH, AST and ALT in human patients infected with Trichinella pseudospiralis. Increased serum levels of ALT in pigs infected with T. spiralis have also been previously reported (Ribicich et al 2007). However, elevated serum levels of these enzymes are not necessarily indicative of Trichinella infection, as there may be other causes (Koudela & Schanzel 1980;Ribicich et al 2007;Srivastava & Chosdol 2007;Tassi et al 1995;Wisniewska 1970).…”

Comparisons between rats and human patients indicated that an increase in enzyme levels is dependent on the individual response from the host rather than being correlated with intensity of infection or clinical severity (Wisniewska 1970).…”

Fifteen crocodiles were randomly divided into three groups of five animals. They represented high-infection, medium-infection and low-infection groups of 642 larvae/kg, 414 larvae/kg and 134 larvae/kg bodyweight, respectively. The parameters assessed were blood glucose, creatine phosphokinase (CPK), lactate dehydrogenase (LDH), aspartate transaminase (AST) and alanine transaminase (ALT). The humoral immune response to Trichinella zimbabwensis infection was evaluated in all three groups by an indirect ELISA method. The results showed deviations from normal parameters of blood glucose, CPK, LDH, AST and ALT when compared with reported levels in uninfected reptiles. Contrary to studies involving mammals, hypoglycaemia was not observed in the infected groups in this study. Peak values of blood glucose were reached on post-infection (PI) Day 49, Day 42 and Day 35 in the high-infection, medium-infection and low-infection groups, respectively. Peak values of LDH and AST were observed on PI Day 56, Day 49 and Day 42 in the high-infection, medium-infection and low-infection groups, respectively. Peak values of CPK were observed on Day 35 PI in all three groups. Peak ALT values were reached on Day 56 in the high-infection group and on Day 28 PI in both the medium-infection and low-infection groups. No correlations between the biochemical parameters and infection intensity were observed. Peak antibody titres were reached on Day 49 PI in the medium-infection group, and on Day 42 PI in both the high-infection and low-infection groups. Infection intensity could not be correlated with the magnitude of the humoral immune response or time to sero-conversion. Results from this study were in agreement with results reported in mammals infected with other Trichinella species and showed that antibody titres could not be detected indefinitely.

“…The cougar in this work showed a better overall condition than the one described by Hidalgo et al (2013). Although the disease has been reported in animals (Rice, et al, 1990;Ribicich, et al, 2007;Bowman, 2009;Ribicich, et al, 2013), the infecting dose necessary for clinical signs is usually high, resulting in higher larvae densities than that observed in this report. Another likely cause for the lack of clinical signs is that the animal is in the chronic phase of the infection.…”

“…1). The cougar did not show external physical signs of acute trichinellosis (Ribicich, et al, 2007;Bowman, 2009;Ribicich, et al, 2013); it only showed facial lesions attributable to the cause of death.…”

“…Conversely, the transmission of parasites between native and introduced mammals is a major issue in conservation biology, because introduced species (including parasites) are one of the most signifi cant causes of species loss (Wilcove, et al, 1998;Wilcove & Master, 2005). Given that clinical diseases in animals experimentally infected by Trichinella infection have been documented, especially when infecting dose is high (Rice, et al, 1990;Ribicich, et al, 2007;Bowman, 2009;Ribicich, et al, 2013), it is expected that native carnivores would show clinical signs after a highly loaded prey consumption. From this point of view, the identifi cation of the Trichinella species circulating in wild mammals allows us to establish whether these parasites were or not transmitted from introduced hosts.…”

Research Note. Trichinella spiralis parasitizing Puma concolor: first record in wildlife in Chile

et al. 2015

SummaryThe genus Trichinella is widespread in all continents but Antarctica. The only way to identify the species/genotypes is through molecular analyses. In Chile, only one study has reported Trichinella larvae in a cougar, but the species of Trichinella was not identifi ed. In this work, the fi nding of Trichinella larvae in a cougar, together with their genotypic identifi cation, is the fi rst documentation of such in Chile. The cougar was found run over by a vehicle in the Biobío Region. Larvae were isolated following artifi cial digestion of the diaphragm and analyzed by means of multiplex polymerase chain reaction (PCR). A PCR product of 173 base pairs allowed for the classifi cation of the larvae as T. spiralis. It is the fi rst record of the species in Chilean wildlife. This fi nding in Chile is interesting in terms of human health, suggesting a possible role of the cougar as a reservoir for this parasite
