Zoonotic smooth and rough Brucella in dogs: seroprevalence and associated facto...
Bernardino,Maria das Graças da Silva; Silva,Edijanio Galdino da; Nogueira,Denise Batista; Angelo,Débora Ferreira dos Santos; Diniz,Vanda Teixeira JalesABSTRACT: Canine brucellosisis an infectious disease caused by bacteria of the genus Brucella, with world wide distribution and zoonotic impact, and in humans and animals is a neglected disease. In the present study, the sero prevalence of B. canis and B. abortus were determined in a probabilistic sample of housed dogs from the Atlantic Rainforest area of the state of Paraíba, Brazil, and the factors associated...
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.
High seroprevalence and associated factors for visceral leishmaniasis in dogs i...
Bernardino,Maria das Graças da Silva; Angelo,Débora Ferreira do Santos; Silva,Raizza Barros Sousa; Silva,Edijanio Galdino daAbstract Dogs have been implicated as main reservoirs for visceral leishmaniasis (VL) in urban areas. Therefore, studies on this species provide important data for public health. Thus, the objective of the present study was to ascertain the seroprevalence of canine VL (CVL) and the associated factors in the Brejo Paraibano microregion, northeastern Brazil. A total of 409 dogs were sampled from the eight municip...
Clinical aspects and diagnosis of leishmaniasis in equids: a systematic review ...
Limeira,Clécio Henrique; Alves,Clebert José; Azevedo,Sérgio Santos de; Santos,Carolina de Souza Américo Batista; Melo,Marcia Almeida deAbstract Leishmaniases are a group of diseases of zoonotic importance caused by over 20 species of protozoa of the genus Leishmania, in which domestic dogs are considered to be the main reservoir for the disease. However, the involvement of other vertebrates as reservoirs for these parasites has also been investigated. Therefore, the objective of the present study was to carry out a systematic review with meta-...
Isolation and identification of Mycobacterium bovis in bovines with positive re...
Ramos,Joelson Marcolino; Heinemann,Marcos Bryan; Ferreira Neto,José Soares; Souza Filho,Antonio Francisco de; Cárdenas,Nicolás CéspedesABSTRACT: In areas where human tuberculosis and bovine tuberculosis coexist, differentiation between M. bovis and M. tuberculosis is important for monitoring the spread of M. bovis among cattle and from cattle to humans. The objective of this study was to isolate and identify M. bovis in bovines with positive diagnosis identified on tuberculin test in the State of Paraíba, Northeastern Brazil. Thirty-two bovine...
Leptospirosis in native mixed-breed sheep slaughtered in a semiarid region of B...
Costa,Diego Figueiredo da; Silva,Aline Ferreira da; Brasil,Arthur Willian de Lima; Loureiro,Ana Paula Pereira; Santos,Fabrine Alexandre dosABSTRACT: Sheep breeding is an economic activity of great value for the Brazilian livestock industry, and infectious diseases can significantly compromise its productivity. The aim of this study was to detect Leptospira spp. in mixed breed sheep from a semiarid region of the State of Paraíba, Northeast Brazil. In total, 49 blood and renal tissue samples, as well as 25 urine samples, were collected from 49 sheep...
Isolation and identification of Mycobacterium bovis in milk from cows in northe...
Ramos,Joelson Marcolino; Heinemann,Marcos Bryan; Ferreira Neto,José Soares; Filho,Antônio Francisco de Souza; Cárdenas,Nicolás CéspedesABSTRACT: Milk samples from 16 cows that tested positive on the tuberculin test in the state of Paraíba, northeastern Brazil, were used for mycobacteria isolation and identification. Mycobacteria were isolated from five (31.25%) of the 16 milk samples; three samples were classified as M. bovis, and two as belonging to the Mycobacterium genus. This is probably the first study of isolation and identification of M...
Prevalence and risk factors for Toxoplasma gondii in sheep in the State of Para...
Correia,Érico Luís de Barros; Feitosa,Thais Ferreira; Santos,Fabrine Alexandre dos; Azevedo,Sérgio Santos de; Pena,Hilda Fátima de JesusThe aims of this survey were to determine the flock-level and animal-level prevalences of anti-Toxoplasma gondii antibodies in sheep in the State of Paraíba, Northeastern Brazil, and to identify risk factors. Blood samples were collected from 540 sheep in 63 flocks in 14 municipalities in the Sertão mesoregion. To serologically diagnose T. gondiiinfection, the indirect immunofluorescent antibody test (IFAT) was...
Isolation of Actinobacillus seminis from a goat with clinical epididymo-orchiti...
Santos,Fabrine Alexandre dos; Azevedo,Edísio Oliveira de; Azevedo,Sérgio Santos de; Garino Júnior,Felício; Mota,Rinaldo AparecidoThe present study reports the first isolation of Actinobacillus seminis from a goat in Brazil. A four-year-old Moxotó breeding goat in a flock of 70 goats and 65 sheep reared together in the county of Patos, semiarid region of Northeastern Brazil, showed clinical signs of unilateral orchitis and epididymitis. Diagnosis of A. seminis infection was confirmed by association of clinical findings, bacterial isolatio...
