Serological studies on Philippine naegleria isolates
Mice immunized intravenously (IV) and intraperitoneally (IP) with NSRI and RITM Naegleria isolates produced agglutination titers of 1:256 and 1:643 respectively for both homologous and heterologous antisera. Intraperitoneal immunization with adjuvant produced the same titer as in IV route while no a...
