TaqMan PCR for Accurate Diagnosis of Tick-Transmitted Pathogens in Cattle | Research - Kerala, India
π¬ About This Study:
This video discusses a research study that utilized TaqMan-based qualitative Real-Time PCR (qPCR) for the accurate and confirmatory diagnosis of multiple tick-transmitted pathogens affecting the bovine population in Kerala, India. Conventional microscopy-based methods often fail to identify pathogens at the species level, especially when they have similar infective stages. This study highlights the advantages of molecular diagnostics in detecting co-infections and secondary pathogens that impact cattle health.
π Key Findings:
Sample Collection: 60 peripheral blood samples (EDTA) were randomly collected from five private cattle farms in Wayanad & Thrissur districts, Kerala.
Pathogens Detected: The study identified Theileria spp., Mycoplasma haemocanis, and Pasteurella multocida using highly sensitive TaqMan qPCR.
Ct (Cycle Threshold) Values:
Theileria genus: Avg Ct = 12.79 (Range: 4.1β36.19)
M. haemocanis: Avg Ct = 22.42 (Range: 2.66β37.6)
P. multocida: Avg Ct = 20.20 (Range: 2.74β35.72)
(Lower Ct = Higher pathogen load in initial sample)
P. multocida as a Secondary Pathogen: Found to cause severe issues due to immune suppression by primary tick-borne infections.
π‘ Implications for Cattle Health Management:
Vaccination Strategies: Co-infections may interfere with seroconversion & duration of immunity, requiring tailored vaccination programs.
Need for Advanced Diagnostics: Microscopy alone is insufficient; molecular methods like TaqMan PCR improve detection accuracy.
π Methodology:
DNA extraction: High Pure PCR Template Preparation Kit
Primer efficiency tested via standard curve using custom-synthesized positive clones
Cycling conditions optimized for each pathogen
π Why This Matters?
Tick-borne diseases severely impact cattle productivity. This study emphasizes the need for advanced diagnostic tools like TaqMan qPCR to detect multiple pathogens simultaneously, aiding in better treatment and vaccination planning by the Department of Animal Husbandry, Kerala.
