Neosporosis is an infectious disease which is caused by a protozoan called and characterized by endemic and epidemic abortions in adult cattle and congenital encephalomyelitis in calves. Our case was a female calf from the Holstein breed which was born in a farm with abortion and infertility problems and was unable to stand up after birth.. It was stated that it was the third pregnancy of the mother cow and that the previous pregnancy was aborted in the fifth month. In clinical examination, sucking reflex of the calf was present and there was spastic paralysis starting from pelvic muscle in rear limbs. Blood (EDTA and spare tube) sample was taken from the cow and from the calf before sucking first colostrum and cerebrospinal fluid was collected from the calf.. Based on the clinical and serological findings, a diagnosis of congenital neosporosis was made. As a result, neosporosis must be considered in the clinical diagnosis of calves with neurological symptoms during the neonatal period.

Article Synopsis
- A 3-month-old Cane Corso puppy suffered from severe symptoms, including hindlimb lameness and eventual paralysis, leading to its critical condition at the Purdue Veterinary Hospital.
- Blood tests revealed significant abnormalities, including high levels of creatine kinase, and the puppy tragically went into cardiac arrest shortly after diagnostics.
- Necropsy findings showed widespread muscle degeneration and inflammation, along with protozoal cysts confirmed by elevated antibody levels, highlighting disseminated neosporosis as a rare but critical cause of ascending paresis in young dogs.

This study aimed to assess the fluctuations of antibody serum titers for and in naturally infected crossbred cows during gestation and to investigate transplacental transmission of ; 51 cows were monitored during pregnancy by monthly serologic testing by indirect fluorescent antibody test. 33 cows were seronegative for both and , 10 were seropositive only for , 5 were seropositive only for and 3 were seropositive for both and . In both protozoan infections, great variation in antibody levels in pregnant cows was observed, and there was significant increase (p<0.

Article Synopsis
- The study isolated four new strains of Neospora caninum from various sources, including calves affected by abortion and asymptomatic cases, and characterized their differences in phenotype and microsatellites.
- Researchers explored the implications of these variations on virulence, invasion, and vertical transmission through cell cultures and murine models.
- Genomic analyses revealed that the NcURU isolates exhibit low virulence and distinct phenotypic traits, providing insights for future diagnostic and vaccine development.

Introduction: and are closely related obligate intracellular protozoan parasites. They are considered to be the major causes of infectious abortions and congenital abnormalities in livestock worldwide resulting in huge economic losses. Currently, there are no reports on the prevalence of neosporosis or toxoplasmosis in cattle in Beheira, Egypt's most important region for cattle industry.
