Characterization of Immune Cell Infiltration in the Placentome of Water Buffaloes (Bubalus bubalis) Infected with Neospora caninum During Pregnancy
(Elsevier, 2014-05)Neospora caninum infection in cattle stimulates host immune responses, which may be responsible for placental damage leading to abortion. Susceptibility of water buffaloes (Bubalus bubalis) to neosporosis is not well ... -
Cytokine expression in the placenta of pregnant cattle after inoculation with Neospora caninum
(Elsevier, 2014-09-15)Neospora caninum is recognized as a major cause of reproductive losses worldwide but its pathogenesis is not completely understood. Immune mediated placental pathology has been reported as being responsible for compromising ... -
Development of maternal and foetal immune responses in cattle following experimental challenge with Neospora caninum at day 210 of gestation
(BMC, 2013-10)This study examined the immunological responses of pregnant cattle and their foetuses following an experimental challenge with live Neospora caninum tachyzoites at day 210 of gestation. Animals were bled prior to and weekly ... -
Evaluation and comparison of serological methods for the detection of bovine neosporosis in Argentina = Evaluación y comparación de pruebas serológicas para la detección de la neosporosis bovina en Argentina
(Asociación Argentina de Microbiología, 2015-12)Neospora caninum is a protozoan parasite that causes abortion and important economic losses in cattle worldwide. The accurate diagnosis of neosporosis is essential for management and control measures. The aims of this study ... -
Evaluation of frequency of antibodies against Neospora caninum, Toxoplasma gondii and Brucella melitensis, risk factors and spatial distribution of infection in goat and sheep flocks from Argentina
(Elsevier, 2023-11)Neospora caninum, Toxoplasma gondii and Brucella melitensis are pathogens that cause abortion in small ruminants. Besides, B. melitensis and T. gondii are zoonotic pathogens. The aim of this study was to describe the ... -
Evaluation of frequency of antibodies against toxoplasma gondii, neospora caninum and Sarcocystis spp. and transmission routes in sheep from Humid Pampa, Argentina
(2018)The aim of this study was to describe the frequency of ovine specific antibodies to Toxoplasma gondii, Neospora caninum and Sarcocystis spp. and to estimate different transmission routes of these infections. One hundred ... -
Experimental inoculation of Neospora caninum in pregnant water buffalo
(Elsevier, 2012-06-08)The aim of this study was to characterize the pathogenesis of Neospora caninum in experimentally inoculated pregnant water buffalo (Bubalus bubalis). Twelve Mediterranean female water buffaloes ranging in age from 4 to 14 ... -
Fate of Neospora-seropositive animals: an opinion
(Sociedad Chilena de Parasitología, 2005-12)Neospora caninum is an abortive protozoon in cattle, which causes severe economic losses worldwide. Chronically infected cattle however develop immune responses protecting against further Neospora induced abortions. ... -
First report of seroprevalence of Toxoplasma gondii and Neospora caninum in dairy sheep from Humid Pampa, Argentina
(Springer, 2013-10)The aim of this study was to describe the occurrence of antibodies to Toxoplasma gondii and Neospora caninum in dairy sheep from the Humid Pampa region, Argentina. Blood samples from 704 dairy sheep belonging to six flocks ... -
Frequency of Neospora caninum infections in beef cow–calf operations under extensive management
(2016-03-30)The aim of this study was to evaluate the frequencies of Neospora caninum horizontal and vertical transmissions in beef cow–calf operations under three different extensive management systems: group A: 0.75 head per hectare ... -
High rate of transplacental infection and transmission of Neospora caninum following experimental challenge of cattle at day 210 of gestation
