• Researches for canine lepotspirosis were carried out on the 471 stray dogs captured at Sakai-city, 11 at Kochi-city and 23 at Fukui-city and following results were obtained. 1. The 41 strains of leptospira were isolated from the stray dogs at Sakai, of which 26 were proved to be L. canicola. Remaining 15 were identified indirectly by host serum, of which 11 were L. canicola and 4 were L. icterohaemorrhagiae. Three strains were isolated in Kochi and 2 in Fukui and all of them were L. canicola. All cases carrying leptospira in their kidneys were serologically positive. 2. Out of the 471 serum samples of Sakai, 227 (48.2%) were positive by serological examination, of which 202 were positive with L. canicola, 14 with L. icterohaemorrhagiae and 11 showed same titers with L. canicola and L. icterohaemorrhagiae. Each 4 samples of Kochi and Fukui were positive with L. canicola and remaining one of Kochi with L. icterohaemorrhagiae. 3. Out of the 505 kidneys of Sakai, Kdchi and Fukui, 247 (48.9%) had various lesions of interstitial nephritis which were classified in the following 4 types according to the pathological process, i.e. I-type (acute, slight), II-type (acute, severe), III-type (subacute) and IV-type (chronic). Interstitial nephritis was observed in all of the 46 kidneys carrying leptospira and also in 212 (89.8%) of the 236 serologically posive cases, whereas in only 35 (13.0%) of 269 serologically negative ones. Thus the considerable correlations between leptospira isolation, antibodies and interstitial nephritis were demonstrated.
