Introduction

Neospora Ab refers to antibodies produced in response to infection by the parasite Neospora caninum, which primarily affects cattle and is a major cause of abortion in livestock. The Detection of Neospora Ab is crucial for the management and control of neosporosis in agricultural settings.

What is Neospora Ab?

Neospora Ab are immunoglobulins produced by the host organism as a defense mechanism against Neospora caninum. This protozoan parasite primarily affects cattle, leading to reproductive issues such as abortions, stillbirths, and early fetal death. The presence of Neospora Ab is indicative of exposure to the parasite, and their levels can be used to assess the infection status of an animal. Quantitative serological assays measure these antibodies, providing insight into herd health status.

Detection Methods

The detection of Neospora Ab is primarily conducted through serological tests. The following are the main methodologies:

Enzyme-Linked Immunosorbent Assay (ELISA)

ELISA is the most commonly used method due to its high sensitivity and specificity. It involves the following parameters:

• Sensitivity: ≥95%
• Specificity: ≥98%
• Turnaround Time: 24-48 hours

Indirect Fluorescent Antibody Test (IFAT)

IFAT is a microscopy-based method providing visual confirmation of antibodies, with the following specifications:

• Sensitivity: 90-95%
• Specificity: 95-97%
• Turnaround Time: 48-72 hours

Polymerase Chain Reaction (PCR)

While PCR targets the DNA of Neospora caninum and not antibodies directly, it is often used in conjunction with serological tests to confirm active infection:

• Sensitivity: 80-90%
• Specificity: 98-99%
• Turnaround Time: 24-48 hours
