Immunological characterization of recombinant Wuchereria bancrofti cuticular collagen (COL-4) as putative vaccine candidate for human lymphatic filariasis.

Objective: To elucidate immunoprophylactic potential of recombinant Wuchereria bancrofti (W. bancrofti) cuticular collagen (COL-4) in BALB/c mice and filarial clinical samples.

Methods: col-4 gene was PCR amplified from W.

Evaluation of synthetic peptides of WbSXP-1 for the diagnosis of human lymphatic filariasis.

Parasitic nematodes infect nearly half of the world's human population, resulting in significant morbidity and mortality. Though filariasis is not fatal, it is the second leading cause of permanent and long-term disability worldwide. Filariasis has a spectrum of disease manifestation and infectivity found among the infected individuals and also goes unnoticed for years.

Molecular characterization of a truncated antigen (Wb14) of SXP-1 of Wuchereria bancrofti from four endemic regions in India.

Wb14 of Wuchereria bancrofti, an orthologue of Brugia malayi SXP-1 and W. bancrofti SXP-1, was amplified from genomic DNA of W. bancrofti microfilaria collected from four distant geographical locations in India viz.

Brugia malayi: comparison of protective immune responses induced by Bm-alt-2 DNA, recombinant Bm-ALT-2 protein and prime-boost vaccine regimens in a jird model.

Immunization of jirds with Bm-alt-2 elicited partial protection against challenge infection with the filarial parasite Brugia malayi. In this study, we initially compared the protective immune responses elicited following immunization with recombinant Bm-ALT-2 protein regimen and Bm-alt-2 DNA regimen. These studies showed that protein vaccination conferred approximately 75% protection compared to DNA vaccination that conferred only 57% protection.
