A new leptospiral serovar from India in the Javanica serogroup.

A new serovar in the Javanica serogroup is described after parallel investigation by the 'classical' comparative cross-agglutinin absorption test method and by a method derived from factor analysis. The strain was isolated from a bandicoot (Bandicota bengalensis) trapped in Mannuthy, Trichur, India. The serovar name menoni with reference strain Kerala, is proposed.

Three new leptospiral serovars from Kenya.

Three new serovars isolated from rodents in Kenya are described. The strains were investigated by the 'classical' comparative cross-agglutinin absorption test method. In the Tarassovi serogroup the new serovar kanana with reference strain Kwale is proposed and in the Autumnalis group the new serovar lambwe with reference strain Lambwe. The new serovar kenya with reference strain Njenga seems to have a position in between the Ballum and Ranarum serogroup.

A new leptospiral serovar in The pyrogenes serogroup.

A new leptospiral serovar in the Pyrogenes serogroup is described. Parallel investigations by the 'classical' cross-agglutinin absorption test method and the 'factor analysis' method determined the serological properties of the new serovar. The serovar name kwale with reference strain Julu is proposed.

A new leptospiral serovar in the Australis serogroup.

A new serovar in the Australis serogroup is described after parallel investigations by the "classical" comparative cross-agglutinin absorption test method and by a method derived from factor analysis. The serovar name ramisi with reference strain Musa is proposed.

Two new leptospira serovars belonging to the Hebdomadis serogroup.

Two new serovars in the leptospira Hebdomadis serogroup are described following parallel investigations by the "classical" comparative cross-agglutinin absorption test method and by a method derived from factor analysis. The serovar names nyanza with reference strain Kibos and dikkeni with reference strain Mannuthi are proposed.
