ABSTRACT
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 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 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 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 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.

PIP: In the course of 2 years of surveillance of whooping cough by fortnightly home visits among a population of 24,000 in a rural area of Kenya, 918 cases were observed with a peak of 218 in December 1974-January 1975. The attack rate was highest (15.8%) during the 1st year of life; for those ages 0-6 it was 12.8%. 90% of the cases occurred in children age 6 or younger. The median age was 3.5 years, the age range 1 month-13 years. Girls were significantly more affected than boys. The overall case fatality rate was 1.3% but among infants, it was 2.5 times higher. In order to contribute to the improvement of immunization coverage in countries where health resources are limited, a schedule of child immunization requiring a minimum number of contacts with the children was introduced into the study area with the aim of evaluating its effectiveness in protecting children from clinical pertussis. In this trial, the effect of 2 and 3 diphtheria-pertussis-tetanus (DPT) vaccine doses was compared. Pertussis agglutinating antibody determinations showed an equally satisfactory response after 2 and 3 DPT vaccine doses. (author's)^ieng

The first isolation of two leptospira strains belonging to the serotype andamana from the kidney of Rattus norvegicus is reported. A strain of this serotype has never before been isolated in the Middle East, nor from any rodent in any other part of the world. Its epidemiologic significance and the classification of this serotype as part of the saprophytic Biflexa species is discussed.

Leptospirosis in swine, caused by serotype lora (serogroup Australis) was detected both serologically and by culture. The most important symptoms consisted in abortion during the final month of gestation and the birth of dead or not viable piglets.
