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...
Digestive diseases of cattle diagnosed at the “Clínica de Bovinos de Garanhuns”...
Soares,Gliére S.L.; Costa,Nivaldo A.; Afonso,José Augusto B.; Souza,Maria I.; Cajueiro,Jobson F.P.; Silva,Jean C.R.; Ferreira,FernandoABSTRACT: Diseases of the bovine digestive system make up an important group of diseases, often being responsible for significant economic losses in the livestock sector. The current work aimed to carry out a retrospective study of the diseases of the digestive system in cattle diagnosed at the “Clínica de Bovinos de Garanhuns”, “Universidade Federal Rural de Pernambuco”, from January 1999 to December 2018. In ...
Seroprevalence and incidence of Toxoplasma gondii and Neospora caninum infectio...
Sevá,Anaiá da Paixão; Chiebao,Daniela Pontes; Brandão,Ana Perola Drulla; Godoy,Silvia Neri; Jimenez-Villegas,Tatiana; Pena,Hilda Fátima JesusAbstract Dogs are hosts of the protozoans Toxoplasma gondii, which causes an important public health disease, and Neospora caninum. Studies that have evaluated toxoplasmosis and neosporosis for prolonged periods in dog populations are rare. We analyzed infection by both parasites in a domestic dog population over three consecutive years in São Paulo state, Brazil. In the 1st, 2nd and 3rd years of collection, 18...
Seroprevalence and incidence of Leptospira spp. in domestic dogs in the Southea...
Sevá,Anaiá P.; Brandão,Ana Pérola D.; Godoy,Silvia N.; Souza,Gisele O.; Souza Filho,Antonio Francisco; Jimenez-Villegas,Tatiana; Heinemann,Marcos BryanABSTRACT: Leptospirosis is a zoonotic disease caused by Leptospira and domestic dogs can act as host of some serovars. In order to analyze the transmission dynamics in a dog population, with and without immunization, a longitudinal study was carried out with a focus to evaluate antibody response and to identify serovars. Blood samples were collected in three consecutive years (2015 to 2017) from 331, 373 and 34...
Actinomycosis, a lurking threat: a report of 11 cases and literature review
Paulo,Catarina Oliveira; Jordão,Sofia; Correia-Pinto,João; Ferreira,Fernando; Neves,IsabelAbstract Actinomycosis remains characteristically uncommon, but is still an important cause of morbidity. Its clinical presentation is usually indolent and chronic as slow growing masses that can evolve into fistulae, and for that reason are frequently underdiagnosed. Actinomyces spp is often disregarded clinically and is classified as a colonizing microorganism. In this review of literature, we concomitantly p...
SSR-based genetic analysis of sweet corn inbred lines using artificial neural n...
Ferreira,Fernando; Scapim,Carlos Alberto; Maldonado,Carlos; Mora,FreddyAbstract Studies on genetic diversity and population structure provide basic information at the molecular level, which is a key input for breeding programs of crop species. This study evaluated the genetic diversity of 12 elite lines of sweet corn, using 20 microsatellite markers. To determine the genetic differentiation among lines, we used an artificial neural network with the self-organizing map (SOM) algori...
Dog and cat population dynamics in an urban area: evaluation of a birth control...
Garcia,Rita C.M.; Amaku,Marcos; Biondo,Alexander W.; Ferreira,FernandoABSTRACT: For canine and feline population management in an urban area, a set of well-developed strategies is required to prevent overpopulation, the abandonment of animals, and zoonosis. An understanding of the dynamics of these populations and a characterization of these populations are necessary for action planning. The proposed strategies should be monitored and evaluated so that canine and feline populatio...
Factors associated with the prevalence of helminths in Mangalarga Marchador hor...
Rosa,Marina H.F.; Garcia,Adriana M.; Daher,Débora O.; Lima,Imara G.; Félix,Marcelle B.; Capellari,Luiz A.; Ferreira,Fernando; Rocha,Christiane M.B.M.ABSTRACT: Horses are highly susceptible to parasitism. Helminth infections cause great harm to the animals and to their breeders. This study aimed at evaluating socioeconomic, cultural and management factors associated with the prevalence of gastrointestinal helminths of horses. A total of 40 farmas the Mangalarga Marchador horse breed were visited in southern Minas Gerais, Brazil, where interviews were conduct...
Cattle trade between and within biomes in the state of Mato Grosso, Brazil
Negreiros,Rísia L.; Grisi-Filho,José H.H.; Dias,Ricardo A.; Ferreira,Fernando; Homem,Valéria S.F.; Ferreira Neto,José S.; Ossada,Raul; Amaku,MarcosABSTRACT: The analysis of animal movement patterns may help identify farm premises with a potentially high risk of infectious disease introduction. Farm herd sizes and bovine movement data from 2007 in the state of Mato Grosso, Brazil, were analyzed. There are three different biomes in Mato Grosso: the Amazon, Cerrado, and Pantanal. The analysis of the animal trade between and within biomes would enable charact...
Frequency and spatial distribution of animal and object hoarder behavior in Cur...
Cunha,Graziela Ribeiro da; Martins,Camila Marinelli; Ceccon-Valente,Marília de Fátima; Silva,Liana Ludielli da; Martins,Flavia Dias; Floeter,DircianeAbstract: This study aimed to establish the frequency and spatial distribution of animal and object hoarding in Curitiba (Paraná State), the eighth most populous city in Brazil. All hoarding complaints received by the City Secretaries of Health, Environment and Social Assistance between September 2013 and April 2015 were collected (n = 226) and suspicious cases were individually investigated. A total of 113/226...
