Serosurvey of anti-treponema pallidum (syphilis), antihepatitis C virus and ant...
Felipetto,Laís Giuliani; Teider-Junior,Pedro Irineu; Silva,Felipe Fortino Verdan da; Couto,Anahi Chechia do; Kmetiuk,Louise BachABSTRACT Homeless persons have been considered as one of the most susceptible populations to sexually transmitted infections. In Brazil, these population experienced an increase of 140% from 2012 to 2020. Accordingly, the present study aimed to assess the seroprevalence of anti-Treponema pallidum, anti-HCV, anti-HIV antibodies, and the risk factors associated with homeless persons in a daytime attendance shelte...
Molecular detection of Leishmania infantum in donkeys and mules under semiarid ...
Limeira,Clécio Henrique; Oliveira,Murilo Duarte de; Araújo Júnior,João Pessoa; Malossi,Camila Dantas; Ullmann,Leila SabrinaAbstract Visceral leishmaniasis is a parasitic zoonosis that mainly affects poorest and most vulnerable populations, and domestic dogs are considered to be the main source of infection to the vector and therefore humans. However, several studies have investigated the role of other vertebrate hosts in the disease cycle. In this context, the aim of the present study was to conduct a survey of Leishmania infantum ...
Leptospira interrogans infection in tegu lizard (Tupinambis merianae), Brazil
Fernandes,Juciê Jales; Pinheiro,Tiago Junior; Costa,Diego Figueiredo; Araújo Júnior,João Pessoa; Malossi,Camila Dantas; Ullmann,Leila SabrinaABSTRACT: We used 12 tegu lizards (Tupinambis merianae) from northeastern Brazil, and we reported nine (75%) Leptospira sp. PCR-positive animals and six (50%) seropositive. Leptospira sp. DNA sequencing revealed 99% similarity with L. interrogans. Our findings indicated that this species may play a role in the transmission of human leptospirosis.
Anti-leptospirosis agglutinins in Brazilian capybaras (hydrochoerus hydrochaeris)
Langoni,Helio; Kuribara,Ivone Yumi; Correa,Ana Paula Ferreira Lopes; Ullmann,Leila Sabrina; Sánchez,Gabriela Pacheco; Lucheis,Simone BaldiniAbstract Background The interest in commercial use of wild animals is increasing, especially regarding raising of capybaras. Although this wild species is potentially lucrative for the production of meat, oil and leather, it is suggested as a probable reservoir of leptospires. Methods Due to the economic importance of this species and the lack of studies concerning leptospirosis, the presence of anti-leptospiro...
Mycobacterium genavense infection in two species of captive snakes
Ullmann,Leila Sabrina; Dias,Ramiro das Neves; Cagnini,Didier Quevedo; Yamatogi,Ricardo Seiti; Oliveira,Jose Paes; Nemer,VivianeAbstract Background: Mycobacterium is an important zoonotic agent with companion, livestock and wildlife animals reportedly playing a role as reservoirs. Although its association with reptiles has been described, the disease cycle remains to be fully established, particularly in snakes. Accordingly, this study aimed to report the occurrence of mycobacteriosis with clinical pneumonia in one exotic python snake (...
Seroprevalence and seroincidence of Leptospira infection in dogs during a one-y...
Morikawa,Vivien Midori; Bier,Daniele; Pellizzaro,Maysa; Ullmann,Leila Sabrina; Paploski,Igor Adolfo Dexheimer; Kikuti,Mariana; Langoni,HélioINTRODUCTION: Leptospirosis is a zoonosis that affects both humans and animals. Dogs may serve as sentinels and indicators of environmental contamination as well as potential carriers for Leptospira. This study aimed to evaluate the seroprevalence and seroincidence of leptospirosis infection in dogs in an urban low-income community in southern Brazil where human leptospirosis is endemic. METHODS: A prospective ...
Detection of anti-Toxoplasma gondiiantibodies in carthorses in the metropolitan...
Finger,Mariane Angélica; Villalobos,Eliana Monteforte Cassaro; Lara,Maria do Carmo Custódio de Souza Hunold; Cunha,Elenice Maria SequetinToxoplasma gondii, the agent for toxoplasmosis, has worldwide distribution. Horses normally play a secondary role in its life cycle, but movement around urban areas, feeding on grass and the increasing use of carthorses for gathering recyclable material in some urban areas of Brazil may increase their exposure to T. gondii infection. The aim of the present study was to investigate the frequency of anti-T. gondi...
Seroprevalence of Toxoplasma gondii infection in cats from Curitiba, Paraná, Br...
Cruz,Marúcia de Andrade; Ullmann,Leila Sabrina; Montaño,Patrícia Yukiko; Hoffmann,Juliano Leônidas; Langoni,Helio; Biondo,Alexander WelkerToxoplasmosis is a worldwide zoonosis caused by the protozoa Toxoplasma gondii which infects all warm-blood vertebrates. This study aimed to assess the seroprevalence of anti-Toxoplasma gondii antibodies in a population of domestic cats seen at a major cat-only veterinary clinic in Curitiba, Paraná State, Southern Brazil. Serum samples were processed by indirect immunofluorescence assay (IIFA) for the detection...
Surveillance of canine visceral leishmaniasis in a disease-free area
Frehse,Michele Salmon; Greca Júnior,Haroldo; Ullmann,Leila Sabrina; Camossi,Lucilene Granuzzio; Machado,Juliana G.; Langoni,HélioLeishmaniasis is an important re-emergent parasitosis worldwide, particularly in tropical countries. There are no reports of autochthonous disease in the State of Paraná, southern Brazil. No surveillance has been carried out in the most populated areas such as the city of Curitiba and its surroundings. The purpose of the present study was to determine the seroprevalence of visceral leishmaniasis in dogs at the ...
