Investigation of canine visceral leishmaniasis in a non-endemic area in Brazil ...
Sevá,Anaiá da Paixão; Brandão,Ana Pérola Drulla; Godoy,Silvia Neri; Soares,Rodrigo Martins; Langoni,Helio; Rodrigues,Bruna CristineAbstract INTRODUCTION: Visceral leishmaniasis (VL) is an important zoonosis in Brazil. Previous identification of parasitized dogs can also help prevent the disease in humans, even in non-endemic areas of the country. The Brazilian Ministry of Health recommends diagnosis in dogs using a DPP® (rapid test) as a screening test and an immunoenzymatic assay (ELISA) as a confirmatory test (DPP®+ELISA), and culling in...
Molecular characterization of Toxoplasma gondii and Sarcocystis spp. in raw kib...
Langoni,Helio; Generoso,Diego; Hayasaka,Ênio Yoshinori; Mantovan,Karine Bott; Menozzi,Benedito Donizete; Richini-Pereira,Virgínia BodelãoAbstract Toxoplasmosis occurs worldwide causing economic losses to the animal production and problems to the public health. The study aimed to detect Toxoplasma gondii and Sarcocystis spp.in 141 meat products from commercial meat cuts of pork, beef, and kibbeh sold in commercial markets from Botucatu, SP, Brazil. Samples were bioassayed in mice to isolate the parasite, and the parasite DNA detected by PCR targe...
Cumulative incidence and spatial distribution of dogs exposed to Toxoplasma gondii
Olbera,Alisson Vinícius Gimenes; Fornazari,Felipe; Babboni,Selene Daniela; Rossi,Rodolfo Santos; Sevá,Anaiá Paixão; Latosinski,Giulia SoaresAbstract Toxoplasma gondii is one of the most important protozoa parasites worldwide. Although many seroprevalence studies have been performed in domestic and wild species, data on the cumulative incidence and the spatial distribution of T. gondii in animals are extremely scarce. In the present study, dogs from Botucatu municipality, São Paulo state, were followed for one year and their blood samples were colle...
Microbiological and molecular detection of Mycoplasma bovis in milk samples fro...
Salina,Anelise; Timenetsky,Jorge; Barbosa,Maysa S.; Azevedo,Cristiane M.; Langoni,HelioABSTRACT: The genus Mycoplasma includes more than 200 bacterial species that cause disease in animals. It is responsible for causing mastitis in bovines and may be related to other manifestations, such as arthritis and pneumonia in calves and heifers. The present study aimed to detect Mycoplasma bovis isolated from milk samples of bovine clinical mastitis, and to compare the isolation rates in two culture media...
Serological and molecular investigation of Leishmania spp. infection in cats fr...
Bezerra,José Artur Brilhante; Oliveira,Ilanna Vanessa Pristo de Medeiros; Yamakawa,Ana Carolina; Nilsson,Mariana Guimarães; Tomaz,Klívio Loreno RaulinoAbstract The aim of this study was to investigate the occurrence of Leishmania spp. antibodies, and its association with feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV), in domestic cats from an area endemic for canine and human leishmaniasis in Rio Grande do Norte State, Brazil. Ninety-one cats were subjected to a complete clinical exam, and blood samples were collected. An epidemiological...
Bacterial identification, somatic cell count, antimicrobial profile and toxigen...
Lavor,Ubirajara L.; Guimarães,Felipe F.; Salina,Anelise; Mioni,Mateus S.R.; Langoni,HelioABSTRACT: Bovine mastitis has a negative impact on milk production and can pose risks to public health. The present study aimed to evaluate the quality of bovine milk from small farms in the Botucatu/SP region. Somatic cell counts (SCC), identification of pathogens involved in mastitis, and sensitivity antimicrobial profile of staphylococci isolated were performed. The presence of enterotoxin encoding genes in ...
INFECÇÃO POR Toxoplasma gondii, Neospora caninum, Leishmania major E Trypanosom...
Paz,Giselle Souza da; Colhado,Bruna da Silva; Anton,Mariane Martinez; Rocha,Katarine de Souza; Silva,Daniela Barbosa daResumo Realizou-se inquérito sorológico para Toxoplasma gondii, Neospora caninum, Leishmania spp. e Trypanosoma cruzi em cães dos municípios de Castanhal e Belém, no Estado do Pará, e estudou-se a associação entre os animais sororeagentes e fatores como sexo, idade, acesso a rua e procedência dos animais. Foram utilizados 269 cães de diferentes idades, sadios, provenientes de abrigos de animais, canil comercial...
Prevalência de Mycoplasma bovis em rebanhos de vacas leiteiras
Manzi,Marcela P.; Joaquim,Sâmea F.; Guimarães,Felipe F.; Bruder-Nascimento,Ariane Cristina M.O.; Pantoja,José Carlos F.; Langoni,HelioRESUMO: Mycoplasma é um patógeno altamente contagioso, podendo causar mastite, pneumonia, artrite, entre outras enfermidades. Seu isolamento requer meios e condições específicas devido ao seu crescimento fastidioso. Devido à complexidade do seu diagnóstico, acredita-se que a real prevalência de casos de mastite por micoplasma seja subestimada. O objetivo do presente estudo foi identificar a prevalência de Mycop...
Considerações sobre o tratamento das mastites
Langoni,Helio; Salina,Anelise; Oliveira,Gabriela Capriogli; Junqueira,Nathália Brancato; Menozzi,Benedito Donizete; Joaquim,Sâmea FernandesRESUMO: A mastite é considerada o maior problema dos animais destinados à produção de leite. Altera a sua composição e aumenta a contagem de células somáticas (CCS). Os micro-organismos envolvidos na doença podem ser origem infecciosa, como Staphylococcus aureus, ou ambiental, tal como Escherichia coli. A cultura bacteriana é uma ferramenta de diagnóstico e auxilia na detecção do patógeno causador da mastite. N...
Genotyping of Toxoplasma gondii and Sarcocystis spp. in road-killed wild mammal...
Richini-Pereira,Virgínia Bodelão; Marson,Pâmela Merlo; Silva,Rodrigo Costa da; Langoni,HelioAbstract INTRODUCTION: Road-killed wild animals host zoonotic pathogens such as Toxoplasma gondii, offering a new opportunity for the epidemiological study of these infectious organisms. METHODS This investigation aimed to determine the presence of T. gondii and other apicomplexan parasites in tissue samples of 64 road-killed wild animals, using polymerase chain reaction (PCR). Positive samples were then typed ...
