Despite this significance, few studies address the parasite epidemiology of these species in the Caribbean region and particularly in the island of Trinidad and Tobago where the iguana is recognized as a popular 'wild' meat animal. This study investigates the presence of gastrointestinal (GI) parasites in both captive and wild Green iguana populations in Trinidad and Tobago. A total of 52 faecal samples were obtained from wild (n=26) and captive (n=26) iguana populations across both islands and then analysed for parasite egg presence. Results indicated no significant difference between the captive status and sex for parasite load and diversity between captive and wild iguanas. Overall, most individuals exhibited two types of parasite eggs in their faeces (Oxyurids and Ascarids), with three distinct parasite egg types identified (Ascarids, Oxyurids and Tapeworms). This study reveals the parasite load and diversity of GI parasites in Trinidad and Tobago iguana populations, offering insights crucial for wildlife disease and conservation management in the region.","PeriodicalId":55326,"journal":{"name":"Brazilian Journal of Biology","volume":"85 ","pages":"e289502"},"PeriodicalIF":0.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143765880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To do this, DNA was extracted from the blood of buffaloes and was subjected to PCR testing and sequencing of the genes NC3 and MICB. The RNA extracted from the placentome and intercotyledonary region of buffaloes in their first (n = 6), second (n = 6) and third (n = 6) trimesters of gestation was subjected to real-time PCR. Explants were created using the chorioallantoic membrane and two experimental groups were established: control and stimulated with LPS for four hours to evaluate the gene expression profile. Analysis on the sequences obtained showed that the genes NC3 and MICB of buffaloes were homologous with those of cattle, with high similarity in the analysis on the sequence variation pattern. The gene expression analysis showed that the genes assessed were transcribed at stages and in placental tissue that differed from what was seen in cattle. The transcription of these genes varied in the tissues studied, with greater transcription of MICB in the intercotyledonary region over the first third of gestation, while the genes studied in the placentome presented low rates of transcription. The trophoblastic cells of the chorioallantoic membrane stimulated with LPS for six hours did not present non-classic MFC-I transcription alterations. The present study therefore provides additional knowledge regarding the immune regulation of placental tissues of buffaloes.","PeriodicalId":55326,"journal":{"name":"Brazilian Journal of Biology","volume":"85 ","pages":"e281304"},"PeriodicalIF":0.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143765878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study aimed to determine the prevalence of hepatitis B and C among the general population of Bahawalpur, along with various recognized risk factors. Samples were collected from December 2021 to May 2022. In total, 263 blood samples were collected from the patients who visited Bahawalpur Victoria Hospital, Bahawalpur Pakistan. A rapid diagnostic test (ICT) was used to diagnose Hepatitis B surface antigen and anti-HCV, followed by an enzyme-linked immunosorbent assay (ELISA). The data were analyzed using IBM SPSS version 22. In total, 263 samples were tested; 5.3% (14/263) tested positive for HBV, 25.4% (67/263) tested positive for HCV, and 0.76% (2/263) were co-infected. The study found a significant association between illiteracy 24% (63/263) and literacy 7.6% (20/263) (P = 0.001), age (31-40 years) 11% (29/263) (P = 0.027), hospitalization 38% (100/263) versus non-hospitalization 62% (163/263) (P = 0.008), and patients who had received any dental treatment 20.9% (55/263) versus those who had not 79.1% (208/263) (P = 0.057).
