Several trichomonad pathogens are of significant veterinary importance due to their role in diseases that cause high mortality rates in chickens. Despite the importance of Trichomonadida in poultry health, molecular studies on these protozoa in North Africa are limited. This study addresses this gap by investigating the genetic diversity and evolutionary relationships of Trichomonadida isolated from G. gallus domesticus and its nematode parasite Heterakis gallinarum (Schrank, 1788) in Tunisia, using a multilocus molecular approach with 18S rRNA and α-actinin 1 genes. Based on both markers, all Tunisian haplotypes, which clustered with those from France, were found to belong to genotype2. 18S rRNA analysis revealed the existence of protozoans such as Histomonas meleagridis (Smith, 1895) and Parahistomonas wenrichi Lund, 1963 in coinfection with H. gallinarum, confirming a possible mixed infection. Additionally, when analysing caecal samples, other Trichomonadida species were identified, including Simplicimonas sp. and Tetratrichomonas gallinarum (Martin et Robertson, 1911). These findings suggest a complex protozoan community within the studied hosts. Phylogenetic analysis revealed a close relationship between H. meleagridis and P. wenrichi, as well as between Simplicimonas sp. and the Monoceromonas-Tritrichomonas group. Both H. meleagridis genotypes 1 and 2 exhibited a sister-group relationship with P. wenrichi, with strong support for a common evolutionary origin. Tetratrichomonas gallinarum was basal in the tree, suggesting early divergence in the Trichomonadida lineage. This study provides, for the first time, insights into the genetic diversity of trichomonadids in Tunisia. The 18S rDNA locus proved to be effective for assessing the genetic diversity of H. meleagridis, P. wenrichi, T. gallinarum and Simplicimonas sp. and showed a possible mixed infection. The findings provide valuable insights into the genetic characteristics of these parasites in Tunisian poultry farms and contribute to the understanding of Trichomonadida diversity, enhancing disease control and prevention efforts.</p>","PeriodicalId":55154,"journal":{"name":"Folia Parasitologica","volume":"72 ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145336693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Another root was studying behavioural changes and cytokine gene expression in the brain of rodents sensitised and exposed to aeroallergens. We \"piggy-backed\" our project funded to study coupling between aeroallergen sensitisation and exposure in patients with recurrent mood disorders, by measuring Toxoplasma gondii (T. gondii) antibodies in existing samples, and found associations between IgG serointensity and past suicide attempts. Successively, we then reported significant associations between T. gondii seropositivity and/or serointensity and suicidal behaviour in patients with schizophrenia in Germany, recent attempters in Sweden, and longitudinally in a cohort of Danish mothers. In the Danish mothers the exposure to T. gondii preceded self-directed harm and violent suicide attempts; the association was stronger with higher serointensity strata demonstrating a dose-effect. Furthermore, we identified links between T. gondii IgG and suicide endophenotypes of aggression and impulsivity in both individuals with no history of mental illness, and in patients with Intermittent Explosive Disorder (IED). We also found associations between T. gondii and risk factors of suicidal behaviour such as hopelessness and anhedonia in the Amish, depressive symptoms in pregnant women and women Veterans, frailty in older adults, and cognitive deficits in patients with bipolar disorder. Recently, we reported positive associations between T. gondii IgG serointensity with suicidal ideation, impulsivity, depression scores, and daytime dysfunction due to sleep problems in US Veterans who previously attempted suicide. Toxoplasma gondii emerged rather unexpectedly and then took over a considerable proportion of our neuroimmune research portfolio. It satisfied both intellectual appetites, and brought celebrations of discovery, with three systematic reviews and meta-analyses published to date, and a substantial majority of primary articles confirming our initial observations. Toxoplasma gondii also brought considerable frustrations, such as initial grant application setbacks, inability to completely demonstrate causality and, so far, prophylactic and therapeutic impotence for mental health applications in general. While we do not have, as of today, effective and safe treatments for chronic toxoplasmosis with demonstrated mental health benefits in immunocompetent hosts, there are reasons to be optimistic regarding future discoveries.

Despite extensive parasitological investigations, no definitive host excreting T. crassiceps eggs was found in the zoological facility where the lemur was kept. These results emphasise the possibility of indirect environmental transmission and highlight the susceptibility of lemurs as atypical intermediate hosts.

This study assessed whether pregnant women in the first trimester infected with Toxoplasma gondii have different cytokine levels than uninfected women. This study also examined whether women with discordant test results for toxoplasmosis represent a distinct group or a mixed group composed of infected women with unusually low levels of anti-Toxoplasma antibodies and uninfected women with high levels of cross-reacting antibodies. We measured 18 cytokines (IL-1β, IL-1ra, IL-2, IL-4, IL-7, IL-9, IL-17A, Eotaxin, FGF basic, G-CSF, IFN-γ, IP-10, MCP-1, MIP-1α, MIP-1β, PDGF-BB, RANTES, TNF-α) in 78 pregnant women, classified as Toxoplasma-positive, Toxoplasma-negative or Toxoplasma-discordant (negative by IgG ELISA, positive by complement fixation test [CFT]). Using exploratory factor analysis, we identified two factors, the first explaining 29.6% and the second 24.9% of the total variability in cytokine concentrations. Toxoplasma-positive women scored significantly higher in the second factor, primarily associated with cytokines linked to Th1-driven inflammation and cellular immunity. Specifically, these women exhibited elevated levels of IL-1β, IL-1ra, IL-2, FGF basic and PDGF-BB compared to Toxoplasma-negative women. This finding suggests that pregnant women with latent toxoplasmosis experience some degree of chronic inflammation. Additionally, our results indicate that Toxoplasma-discordant women are likely Toxoplasma-negative individuals with detectable anti-Toxoplasma IgM antibodies. However, as this study focused on pregnant women, further research is necessary to validate these conclusions in broader populations.</p>","PeriodicalId":55154,"journal":{"name":"Folia Parasitologica","volume":"72 ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144692519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
