During 2009-2010, 161 tissue samples (142 placentas, 16 brains, and 3 livers) from aborted ovine fetuses on Sardinia Island, Italy, were tested for toxoplasmosis. Organs that showed a positive result by nested polymerase chain reaction (PCR) targeting the ITS1 region for Toxoplasma gondii were also amplified with 11 genetic markers (SAG1, 5'-SAG2, 3'-SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1, and Apico) and then subjected to PCR/RFLP for genetic typing. T. gondii DNA was found in 5 placentas, 14 brains, and 2 livers by PCR analysis and all isolates displayed Type II alleles at all 11 loci with all 11 markers. The results indicate that the Type II T. gondii is associated with ovine abortion.

Alzheimer's Disease (AD) is the most prevalent type of dementia and is characterized by the presence of senile plaques and neurofibrillary tangles. There are various theories concerning the causes of AD, but the connection between viral and bacterial infections and their potential role in the pathogenesis of AD has become a fascinating area of research for the field. Various viruses such as (HSV-1), (EBV), Cytomegalovirus (CMV), influenza viruses, and Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), as well as bacteria such as (CP), (HP), (), Spirochetes and eukaryotic unicellular parasites (e.

Background: Toxoplasma gondii is a zoonotic parasite with a great impact on the health of Neotropical primates (NP). The aim of this study was to compare the agreement between the immunofluorescent antibody test (IFAT) and the modified agglutination test (MAT) to detect IgG anti-T. gondii antibodies in NP.

Background: transmission can occur during pregnancy if the mother contracts the infection for the first time. Treatment strategies include the use of antimicrobial medications and providing supportive care. Spiramycin is commonly used to treat toxoplasmosis in pregnant women and to hinder the disease's transmission.

Background And Aim: Zoonotic diseases caused by various blood parasites are important public health concerns that impact animals and humans worldwide. The traditional method of microscopic examination for parasite diagnosis is labor-intensive, time-consuming, and prone to variability among observers, necessitating highly skilled and experienced personnel. Therefore, an innovative approach is required to enhance the conventional method.
