Abstract
The study explores the relationship between flumethrin resistance and Anaplasma marginale infection in Rhipicephalus (Boophilus) microplus of cattle in South Gujarat, India. Adult Immersion Test (AIT) was used to assess flumethrin resistance and polymerase chain reaction (PCR) to confirm A. marginale infection. Species-specific PCR resulted in the amplification of 576 bp of msp5 gene of A. marginale in 17.69% (49/277) groups of ticks, and subsequent digestion with EcoRI cleaved it into two distinct segments. Navsari district, noted level Ι resistance [resistance factors (RF) = 1.78-3.34], and A. marginale prevalence was 16.67, 15.38, 23.08, 15.38, and 11.76% in Navsari, Jalalpore, Gandevi, Chikhli, and Vansda sub-districts, respectively. Similarly, Vyara and Dolvan sub-districts of Tapi observed level Ι resistance (RF = 1-3.63), with A. marginale positivity of 21.43 and 22.22%, while Valod and Songhad demonstrated susceptibility, with 14.29 and 12.50% of A. marginale, respectively. Moving to Surat, the Mahuva, Bardoli, Mandvi, Palsana, and Kamrej sub-districts observed the level Ι resistance (RF = 1.94-2.89), coupled with 14.29, 17.65, 20, 20, and 21.43% of A. marginale, respectively. Lastly, in Valsad district, Dharampur, Kaparada, Valsad, and Umbergaon noted level Ι resistance (RF = 1.67-1.81), and corresponding A. marginale positivity rates of 18.18, 19.23, 15.00, and 20.00%. The scatter plot unveiled a significant moderate positive correlation between RF and A. marginale positivity% (p = 0.0362), characterized by a Pearson correlation coefficient (r) of 0.4963. The covariance (1.1814) highlighted fluctuations, while the coefficient of determination (r2) (0.2463) clarified that 24.63% of the variability in A. marginale positivity% could be attributed to the RF.
