This is an ecological, descriptive, retrospective study, with quantitative and qualitative data on the mosquito fauna collected in 10 areas. A total of 2,787 Culicidae were collected and allocated in 8 genera and 23 species. Of the total specimens captured, 2,341 (84%) were females and 446 males (16%). Haemagogus janthinomys occurred in 2.7% (74) of the cases and Haemagogus leucocelaenus in 4.5% (125); Sabethes chlropterus occurred in 0.1% (3) of the cases, Sabethes albiprivus in 1% (28), and Sabethes glaucodaemon in 0.3% (8); Aedes aegypti occurred in 19.7% (548) and Aedes albopictus in 3.9% (108) of the cases. The Sa. glaucodaemon species was recorded for the first time in Goiânia. Yellow fever infection was not detected in the collected specimens. We conclude that the presence of wild vectors, in addition to potential urban vectors, enabled the classification of receptive and vulnerable areas to the circulation of the yellow fever virus. \u0000KEYWORDS: Entomological surveillance; vector mosquitoes; epizootics; yellow fever.","PeriodicalId":513668,"journal":{"name":"Revista de Patologia Tropical / Journal of Tropical Pathology","volume":" 44","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140387945","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}

These nematodes have low host specificity and zoonotic potential, affecting the liver of their hosts. The objective of this work is to describe the first case, as far as the authors are aware, of C. hepaticum causing granulomatous hepatitis in captive Mandrillus sphinx. A necroscopic examination was performed and the organs were removed and evaluated; then, 1 cm³ fragments were collected and preserved in 10% buffered formalin. After fixation, the samples were submitted to histotechnical processing to make histological slides. At macroscopic examination, the liver showed heterogeneous red surface with light brown and whitish areas distributed throughout the parenchyma, with diverse punctiform structures measuring 1 to 3 mm in diameter. Histopathology revealed abundant multifocal granulomas with fibrosis and bioperculated barrel-shaped eggs, typical of C. hepaticum. Artificial tissue digestion of the liver was performed and the morphometric measurements of the parasite were as follows: 0.054 ± 0.002 mm in length, 0.031 ± 0.008 mm in width, wall thickness of 0.004 ± 0.0007 mm and opercula of 0.006 ± 0.001 mm. Parasitism was not the cause of death, but an incidental finding. However, further investigations are essential to choose control and prevention measures to prevent the infection of other animal groups and even humans. \u0000KEY WORDS: Nematoda; parasitism; primates; zoo medicine; wildlife pathology.","PeriodicalId":513668,"journal":{"name":"Revista de Patologia Tropical / Journal of Tropical Pathology","volume":" 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140390480","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}

Multiple factors are related to KS pathogenesis. The interleukin-23 (IL-23) is an immunomodulatory cytokine with pro-carcinogenic role. The aim of this study was to evaluate the detection of IL-23 in cutaneous lesions of patients with KS classic and KS-AIDS. This was a cross-sectional study conducted at the public Hospital in Natal, Rio Grande do Norte, Brazil. This study included 13 biopsies of patients which presented KS with histopathological confirmation. For detection of IL-23, the immunohistochemical analysis was made with monoclonal antibody anti-IL-23. The immunostaining for IL-23 in biopsies was positive in 61.5% (8/13) of cases. Of seven lesions classified as patch-stage, three were positive for IL-23 (42.8%); two of three samples classified as plaque-stage were positive for IL-23 (66.7%); all the nodular-stage lesions were positive for IL-23. The positivity found in KS-AIDS lesions was 66.7% (6/9) and KS classic 50% (2/4). Our data supports the concept that IL-23 might be a pro-carcinogenic mediator, detected in KS lesions, probably favoring the progression of the tumor. \u0000KEY WORDS: Sarcoma; Kaposi; interleukin-23; tumor microenvironment. \u0000 ","PeriodicalId":513668,"journal":{"name":"Revista de Patologia Tropical / Journal of Tropical Pathology","volume":"2 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140396157","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}
