Identification of immunodominant Babesia microti antigens using genome-wide immunoscreening is described. Candidate antigens were screened against sera from patients with clinical babesiosis. Also described are diagnostic assays with high sensitivity and specificity for detecting B. microti-specific antibodies in patient samples using the identified immunodominant antigens.

The present invention concerns a method for expressing a recombinant DNA molecule in a eukaryotic host cell, comprising the steps of: (a) expressing or introducing at least one chimeric protein, in said host cell, wherein said chimeric protein comprises: (i) at least one catalytic domain of a capping enzyme, in particular selected in the group consisting of cap-0 canonical capping enzymes, cap-0 non-canonical capping enzymes, cap-1 capping enzymes and cap-2 capping enzymes; and (ii) at least one catalytic domain of a DNA-dependent RNA polymerase, in particular a bacteriophage DNA-dependent RNA polymerase, (b) constitutively or transiently downregulating the phosphorylation level of subunit a of translation initiation factor eIF2 (eIF2α) in said host cell.

The invention also concerns an isolated nucleic acid molecule or a set of nucleic acid molecules, comprising or consisting of (1) at least one nucleic acid sequence encoding a chimeric protein comprising at least one catalytic domain of a capping enzyme; and at least one catalytic domain of a DNA-dependent RNA polymerase; and (2) at least one nucleic acid sequence downregulating the phosphorylation level of eIF2α in a eukaryotic host cell or encoding a polypeptide downregulating said phosphorylation level; and (3) optionally, at least one nucleic acid sequence encoding a poly(A) polymerase, as well as vectors, kits and cells comprising said nucleic acid molecule or set, and different uses and applications thereof.
