| description | Eimeria tenella, an intestinal parasite, has brought huge economic losses to the poultry industry. The prevalence and severity of the development of drug resistance has increased the challenge of coccidiosis control. We previously identified the enolase 2 of E. tenella (EtENO2) was differentially expressed in drug-sensitive (DS) and drug-resistant strains using RNA-seq. In this study, the expression of EtENO2 in diclazuril-resistant (DZR), maduramicin-resistant (MRR), and salinomycin-resistant (SMR) strains was analyzed by quantitative real-time PCR (qRT-PCR) and western blots. EtENO2 was highly expressed in several drug-resistant strains compared with the DS strain. The qRT-PCR showed that the transcription level of EtENO2 in the field-isolated resistant strains was upregulated compared with the DS strain. The enzyme activity results indicated that the catalytic activity of EtENO2 in the drug-resistant strains was higher than in the DS strain. In addition, qRT-PCR and western blots showed that the expression level of EtENO2 was higher in second generation merozoites (SM) and unsporulated oocysts (UO) than that in sporozoites (SZ) and sporulated oocysts (SO). Immunofluorescence localization revealed that EtENO2 was distributed throughout SZ and SM and on the surface of the parasites. After the SZ invasion DF-1 cells, it was also observed on the parasitophorous vacuole membrane. Our secretion experiments found that EtENO2 could be secreted outside the SZ. This study indicated that EtENO2 might be related to the interaction between E. tenella and host cells and be involved in the development of E. tenella resistance to some anticoccidial drugs. |
