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...
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...
Prevalence of antibodies against Neospora spp. and Sarcocystis neurona in donke...
Gennari,Solange Maria; Pena,Hilda Fátima de Jesus; Lindsay,David Scott; Lopes,Marcos Gomes; Soares,Herbert Sousa; Cabral,Aline DinizAbstract Sarcocystis neurona and Neospora hughesi are coccidian protozoa that can cause neurological illness in horses in America. In this study we report seroprevalence of Neospora spp. andS. neurona in sera of 333 donkeys from the northeastern region of Brazil. Antibodies to Neospora spp. were detected in 2% (7 donkeys) of 333 sera tested by the indirect fluorescent antibody test (IFAT) with a cut-off dilutio...
Demographic characteristics of owned dogs and cats of Votorantim, São Paulo Sta...
Baquero,Oswaldo Santos; Chiozzotto,Evelyn Nestori; Garcia,Rita de Cassia Maria; Amaku,Marcos; Ferreira,FernandoA two-stage cluster sample design was used to estimate population parameters of dogs and cats of the urban area of Votorantim, São Paulo State, Brazil, to support the planning and implementation of population management programs for companion animals. For dogs, the total and density estimates were 27,241 dogs (95% confidence interval [CI]=23,903-30,578) and 951 dogs km-2 (95% CI=835-1,068), respectively. For ca...

Souza,Vanessa Aparecida Feijó de; Cortez,Luiz Ricardo Paes de Barros; Dias,Ricardo Augusto; Amaku,Marcos; Ferreira Neto,José SoaresA space-time analysis of American visceral leishmaniasis (AVL) in humans in the city of Bauru, São Paulo State, Brazil was carried out based on 239 cases diagnosed between June 2003 and October 2008. Spatial analysis of the disease showed that cases occurred especially in the city's urban areas. AVL annual incidence rates were calculated, demonstrating that the highest rate occurred in 2006 (19.55/100,000 inhab...

Paulin,Lília Márcia Silva; Samartino,Luis Ernesto; Conde,Sandra Beatriz; Federsoni,Igor Stefan Poppovic; Ferreira,Fernando; Amaku,MarcosThe objective of the present study was to compare the performance of three serological tests for diagnosis of Brucella abortus infections in buffaloes (Bubalus bubalis). Serum samples collected from 696 adult females were submitted to the competitive enzyme-linked immunosorbent assay (ELISA-C), (I-ELISA), fluorescence polarization test (FPA), 2-mercaptoethanol test (2-ME) and complement fixation test (CFT). The...

Lopes,Marcos Gomes; Mendonça,Ivete Lopes; Fortes,Kleber Portela; Amaku,Marcos; Pena,Hilda de Fátima Jesus; Gennari,Solange MariaThis study aimed to evaluate the presence of antibodies against Neospora caninum, Toxoplasma gondii and Leishmania infantum in dogs attended at the Veterinary Hospital of the Federal University of Piauí, Northeastern Brazil, where there are no reports of the occurrence of N. caninum and T. gondii in dogs. Serum samples from 530 dogs of genders, different ages and breeds from the municipality of Teresina and nea...
Spatial clustering analysis of the foot-and-mouth disease outbreaks in Mato Gro...
Negreiros,Rísia Lopes; Amaku,Marcos; Dias,Ricardo Augusto; Ferreira,Fernando; Cavalléro,João Crisostomo Mauad; Ferreira Neto,José SoaresIn the southern region of Mato Grosso do Sul state, Brazil, a foot-and-mouth disease (FMD) epidemic started in September 2005. A total of 33 outbreaks were detected and 33,741 FMD-susceptible animals were slaughtered and destroyed. There were no reports of FMD cases in other species than bovines. Based on the data of this epidemic, it was carried out an analysis using the K-function and it was observed spatial ...
Comparison of three decontamination methods for Mycobacterium bovis isolation
Ambrosio,Simone Rodrigues; Oliveira,Eugenia Márcia de Deus; Rodriguez,Cesar Alejandro Rosales; Ferreira Neto,José Soares; Amaku,MarcosSixty samples of tissue fragments with lesions suggestive of tuberculosis from bovine abattoirs, kept in saturated solution of sodium borate, were subjected to four treatments: 4% NaOH (Petroff Method), 12 % H2SO4 and 1.5% HPC (1-Hexadecylpyridinium Chloride) decontamination, and physiological saline solution (control). The HPC method showed the lowest contamination rate (3%) when compared to control (88%, p<0....
