Epidemiology and Control of Neosporosis and Neospora caninum
TLDR
This review is focused mainly on the epidemiology and control of neosporosis in cattle, but worldwide seroprevalences of N. caninum in animals and humans are tabulated.Abstract:
Neospora caninum is a protozoan parasite of animals. Until 1988, it was misidentified as Toxoplasma gondii. Since its first recognition in dogs in 1984 and the description of the new genus and species Neospora caninum in 1988, neosporosis has emerged as a serious disease of cattle and dogs worldwide. Abortions and neonatal mortality are a major problem in livestock operations, and neosporosis is a major cause of abortion in cattle. Although antibodies to N. caninum have been reported, the parasite has not been detected in human tissues. Thus, the zoonotic potential is uncertain. This review is focused mainly on the epidemiology and control of neosporosis in cattle, but worldwide seroprevalences of N. caninum in animals and humans are tabulated. The role of wildlife in the life cycle of N. caninum and strategies for the control of neosporosis in cattle are discussed.read more

Bacterial and fungal infectious etiology causing mastitis in dairy cows in the highlands of Boyacá (Colombia).
TL;DR: The infectious agents involved in the development of mastitis in specialized dairies herds in the Highlands of Boyaca, Colombia were determined and Streptococcus agalactiae and Staphylococcus aureus were the most prevalent microorganisms that cause mastitis.
Journal ArticleDOI
Effects of Neospora caninum infection on brain microvascular endothelial cells bioenergetics.
TL;DR: N. caninum is able to grow in HBMECs without markedly disrupting their normal proliferation or mitochondrial integrity, however, it is associated with an increase in infected cell respiration, whether this increase reflects numeric addition of the parasites own respiration or results from an additional energy demand upon the host cell remains to be elucidated.
Journal ArticleDOI
Seroprevalence of antibodies of Neospora spp. and Toxoplasma gondii in horses from southern Italy.
TL;DR: Although T. gondii infection rates were low, the risk of human infection should not be dismissed, particularly in Italy where consumption of raw or undercooked horse meat has a long tradition.

Dose-dependent immunogenicity of a soluble Neospora caninum tachyzoite-extract vaccine formulated with a soy lecithin/β-glucan adjuvant in cattle.

TL;DR: This is the first dose-response study performed in cattle using sNcAg as antigen and the profile and magnitude of the immune response elicit by this vaccine can be modified by the antigen-dose and vaccination schedule.

Dogs are definitive hosts of Neospora caninum.

TL;DR: Dogs are a definitive host of Neospora caninum, and mice inoculated with canine faecal extracts were monitored for evidence of neosporosis using a variety of morphologic, immunohistologic, serologic, and genetic analyses.

A review of Neospora caninum and neosporosis
TL;DR: Neospora caninum is a recently recognized protozoan parasite of animals, which until 1988 was misidentified as Toxoplasma gondii, and its life cycle is unknown.

Newly recognized fatal protozoan disease of dogs
TL;DR: A newly identified parasite, Neospora caninum, structurally distinct from T gondii, was found in 10 dogs and formed meronts in many tissues of the dogs, especially the brain and spinal cord.

Neonatal Neospora caninum infection in dogs: isolation of the causative agent and experimental transmission.
TL;DR: Neospora caninum infection was diagnosed in 5 young dogs from 2 litters with a common parentage that developed hind limb paresis 5 to 8 weeks after birth and was isolated in cell cultures, mice, and dogs inoculated with infected canine tissues.
