Tissue samples of kidney and blood from 57, 50, 50, 51 and 50 cattle from the slaughter house in Bangkok Metropolitan, Nonthaburi, Pathumthani, Nakhon Pathom and Pha Nakhon Si Ayuthaya respectively were collected for the Microscopic Agglutination Test (MAT) to leptospires and Histopathological examination. The MAT of serum samples from Bangkok Metropolitan with titer at 1:50, 1:100 and 1:200 to leptospires were 5, 2 and 1 serovars, respectively. Serum samples from Nonthaburi with titer at 1:50, 1:100 and 1:200 to leptospires were 3, 2 and 1 serovars, respectively. Serum samples from Pathumthani with titer at 1:50 and 1:100 to leptospires weres 4 and 2 serovars, respectively. Serum samples from Nakhon Pathom with titer at 1:50 and 1:100 to leptospires were 8 and 5 serovars, respectively. Serum samples from Pha Nakhon Si Ayuthaya with titer at 1:50 and 1:100 to leptospires were 9 and 5 serovars, respectively. Histopathological examination of kidney lesions were Chronic Interititial Nephritis at cortex area. Bangkok Metropolitan found kidney lesions 22 (38.6 percent) samples, MAT positive 21 samples and MAT negative 1 sample. Nonthaburi, Pathumthani and Nakhon Pathom found kidney lesions 14 (28 percent), 12 (26 percent) and 24 (47 percent) samples, respectively. MAT positive were found all samples. Pha Nakhon Si Ayuthaya found kidney lesions 14 (28 percent) samples, MAT positive 13 samples and MAT negative 1 sample.
