Aspectos epidemiológicos de la neosporosis bovina en el Nordeste español. Una perspectiva clínica
(Asociación Interprofesional para el Desarrollo Agrario, 2009-12)El parásito protozoo intracelular Neospora caninum ha sido descrito en un amplio rango de especies animales y se considera una de las causas más importantes de aborto en ganado vacuno en todo el mundo. En España, la ... -
Chronic Neospora caninum infection and repeat abortion in dairy cows: a 3-year study
(Elsevier, 2007)The serological status of Neospora was monitored in animals older than 6 months in a dairy herd with a 3-year history of prevalent N. caninum and N. caninum-associated abortions. The numbers of animals in the herd tested ... -
Different humoral mechanisms against Neospora caninum infection in purebreed and crossbreed beef/dairy cattle pregnancies
(Elsevier, 2011)The antigen-specific IgG subclass response may be a convenient indicator of the underlying nature of T helper cell regulation. The aim of the present study was to identify possible differences in Neospora caninum-specific ... -
Dynamics of anti-Neospora caninum antibodies during gestation in chronically infected dairy cows
(Elsevier, 2007)The dynamics of antibody production against Neospora caninum during the gestation period was examined in chronically infected dairy cows. Data were obtained from 86 pregnant parous dairy cows, 21 of which had suffered ... -
Early postabortion recovery of Neospora-infected lactating dairy cows
(Elsevier, 2009)This study was designed to assess the reproductive performance of Neospora caninum–infected dairy cows (Bos taurus) after abortion. The population examined was composed of 92 aborting cows subsequently subjected to at ... -
Effects of crossbreed pregnancies on the abortion risk of Neospora caninum-infected dairy cows
(Elsevier, 2009)Previous studies have shown that the use of beef bull semen significantly reduces the rate of abortions due to Neospora caninum in artificially inseminated (AI) seropositive dairy cows. In addition, certain beef breeds ... -
Foetal death in naive heifers inoculated with Neospora caninum isolate Nc-Spain7 at 110 days of pregnancy
(Elsevier, 2016-09)Neospora caninum infection is a leading cause of abortion in cattle worldwide. The pathogenesis of bovine neosporosis, particularly during the second term of gestation when most abortions occur in naturally infected dams, ... -
Progesterone supplementation during mid-gestation increases the risk of abortion in Neospora-infected dairy cows with high antibody titres
(Elsevier, 2007)Progesterone has been reported to reduce Th1 responses during pregnancy. Thus, given that an excessive Th1 response could lead to abortion in Neospora-infected dairy cows, we hypothesized a reduction in abortion risk ... -
Specific anti-Neospora caninum IgG1 and IgG2 antibody responses during gestation in naturally infected cattle and their relationship with gamma interferon production
(Elsevier, 2009)Gamma interferon (IFN-g) production has been attributed a protective role against abortion in Neospora-infected dairy cows. This study investigate possible relationships between plasma levels of the N. caninum-specific ...
