Seroprevalence and hematological abnormalities associated with Ehrlichia canis ...
Paula,Warley Vieira de Freitas; Taques,Ísis Indaiara Gonçalves Granjeiro; Miranda,Vanessa Carvalho; Barreto,Ana Laura GonçalvesABSTRACT: Ticks are significant parasites of dogs in the tropics, where tick-borne pathogens are highly prevalent, especially in areas where tick control measures are frequently neglected. This study investigated the seroprevalence and hematological abnormalities associated with Ehrlichia canis in dogs referred to a veterinary teaching hospital in Central-western Brazil. Out of 264 dogs tested for anti-Ehrlichi...
Anti-Ehrlichia properties of the dichloromethane fraction of Ageratum conyzoide...
Rosário,Carla Janaina Rebouças Marques do; Rocha,Claudia Quintino da; Aguiar,Daniel Moura de; Lima,Cristian Alex Aquino; Coutinho,Denise FernandesABSTRACT: The increasing number of cases of canine ehrlichiosis caused by Ehrlichia canis in hospitals and veterinary clinics has demonstrated the need for a new drug protocol for this disease. Doxycycline is used to treat ehrlichiosis, but the resistance of the microorganism to this treatment protocol, as well as the various side effects to the animals, has become a concern. Several studies have shown a positi...
Detection molecular of Rangelia vitalii in dogs from Parana State, Southern Brazil
Silva,Bianca Ressetti da; Ferreira,Morgana de Fátima Kuteques; Maffezzolli,Gabriela; Koch,Marília de Oliveira; Beltrame,Olair CarlosAbstract Rangelia vitalii infects erythrocytes, leukocytes and endothelial cells of dogs. The present study aimed to report the molecular detection confirmed by sequencing of R. vitalii in the state of Paraná, as well as describe the clinical, hematological and biochemical alterations of the infected dogs. Three sick dogs from the metropolitan area of Curitiba, PR, Brazil, underwent a physical exam, and laborat...
Antibodies anti-Toxoplasma gondii and anti-Neospora caninum in backyard pigs fr...
Minetto,Make Kawatake; Witter,Rute; Oliveira,Anderson Castro Soares de; Minetto,João Augusto; Barros,Marcelo Luís; Aguiar,Daniel Moura deAbstract To estimate the seroprevalence of Toxoplasma gondii and Neospora caninum, using an indirect immunofluorescent assay (IFA), and identify the risk factors associated, serum samples were collected from 1,070 pigs from 320 backyard pig farming in the of Mato Grosso state. The animal-level seroprevalence of T. gondii and N. caninum was 32.48% and 13.49%, respectively, with a herd seroprevalence of 55.63% fo...
Molecular survey of tick-borne pathogens in small mammals from Brazilian Amazonia
Colle,Ana Cláudia; Mendonça,Ravena Fernanda Braga de; Maia,Maerle Oliveira; Freitas,Leodil da Costa; Witter,Rute; Marcili,Arlei; Aguiar,Daniel Moura deAbstract Small non-volant mammals (marsupials and small rodents) were captured at three different timepoints from 23 forest fragments across three municipalities (Alta Floresta, Sinop and Cláudia) covering the Amazonian biome of the Mato Grosso State in Midwestern Brazil. The animal tissues (liver and spleen) and blood were screened using molecular tools for the detection of Babesia, Coxiella, Cytauxzoon, Hepat...
Seroprevalence, spatial analysis and risk factors of infection with Neospora ca...
Schmidt,Ana Carolina; Pacheco,Thábata dos Anjos; Barddal,Janice Elena Ioris; Oliveira,Anderson Castro Soares de; Aguiar,Daniel Moura deAbstract Neosporosis is caused by an obligate intracellular protozoan, Neospora caninum . It is considered one of the most widespread and frequent causes of abortion in cattle worldwide. To evaluate the prevalence of anti-N. caninum antibodies and associated risk factors, serum samples were collected from 2,452 bovines at 262 farms in the northern Pantanal, state of Mato Grosso, Brazil. Each farmer was asked to...
Firocoxib on aqueous humor prostaglandin E 2 levels for controlling experimenta...
Schroder,Deise Cristine; Stocco,Matias Bassinello; Isoton,Deborah de Arruda; Silva,Carla Patricia Amarante e; Braga,Ísis Assis; Silva,Érica Pereira daABSTRACT: This study aimed to evaluate the effects of firocoxib for controlling experimentally-induced breakdown of the blood-aqueous barrier in healthy and Toxoplasma gondii -seropositive cats. Thirty two cats with no ocular abnormalities were used. Groups (n=8/each) were formed with healthy cats that received 5mg g-1 of oral firocoxib (FH) or no treatment (CH) on day 0; seropositive cats for anti -T. gondii s...
Serological evidence of exposure to tick-borne agents in opossums (Didelphis sp...
Melo,Andréia Lima Tomé; Aguiar,Daniel Moura de; Spolidorio,Mariana Granziera; Yoshinari,Natalino Hajime; Matushima,Eliana Reiko; Labruna,Marcelo BahiaAbstract This work involved a serological investigation of tick-borne pathogens in opossums in eight municipalities of the state of São Paulo, Brazil. Serum samples from 109 opossums (91 Didelphis aurita and 18 Didelphis albiventris) were tested to detect antibodies to Rickettsia rickettsii (Taiaçu strain, 1:64 cut-off) and Ehrlichia canis (São Paulo strain, 1:40 cut-off), by indirect immunofluorescence assay (...
Infection by Neospora caninum in dairy cattle belonging to family farmers in th...
Boas,Ricardo Vilas; Pacheco,Thábata dos Anjos; Melo,Andréia Lima Tomé; Oliveira,Anderson Castro Soares de; Aguiar,Daniel Moura deNeosporosis is considered a major cause of abortion among cattle worldwide. The aim of this study was to investigate the prevalence of anti-Neospora caninum antibodies in dairy cattle and correlate them with possible risk factors on 63 small farms (family farms) in the municipality of Ji-Paraná, the main milk-producing region of the state of Rondônia, northern Brazil. For this purpose, 621 serum samples were co...
Detection of Ehrlichia canis in domestic cats in the central-western region of ...
Braga,Ísis Assis; Santos,Luana Gabriela Ferreira dos; Ramos,Dirceu Guilherme de Souza; Melo,Andréia Lima Tomé; Mestre,Gustavo Leandro da CruzEhrlichiosis is a worldwide distributed disease caused by different bacteria of the Ehrlichia genus that are transmitted by arthropod vectors. Its occurrence in dogs is considered endemic in several regions of Brazil. Regarding cats, however, few studies have been done and, consequently, there is not enough data available. In order to detect Ehrlichia spp. in cats from the central-western region of Brazil, bloo...
