A non-human papilloma pseudovirus or virus like particle has at least one papilloma capsid protein codon-optimized for expression in eukaryotic cells or cell lines. A pharmaceutical composition includes the non-human papilloma pseudovirus or virus like particle, and a diagnostic agent, an imaging agent, and a therapeutic agent. A non-human papilloma pseudovirus or virus like particle can be used as a medicament. A method for producing a non-human papilloma pseudovirus or virus like particle involves codon-optimizing of capsid proteins of non-human papillomaviruses for expression in eukaryotic cells, synthesizing of the sequences and cloning of the synthesized sequences into expression vectors, and producing non-human papilloma pseudovirus or virus like particles. t-carrageenan can be used as transduction enhancer for non-human papilloma pseudovirus or virus like particles in vitro.
