In a descending order, distribution of 78 isolates recovered from streak canal swab samples of buffaloes was as follows: S.
Scrutiny of comparative contemporaneous association (defined in the context of the present study as co-occurrence of a microorganism in streak canal swab and quarter foremilk sample) of streak canal organisms with the intramammary organisms in cows and buffaloes revealed that recovery of 44 and 27 isolates, respectively in cows and buffaloes was common to both streak canal swab and quarter foremilk samples (Table 3).

Table 3: Comparative contemporaneous association of streak canal organisms with the intramammary organisms in cows and buffaloes
In cows (n=20), a total of 44 isolates belonging to 18 microbial categories were recovered simultaneously from streak canal swab and foremilk quarter samples.
In a comparable number (n = 20) of buffaloes sampled in the present study, 27 isolates of 15 microbial categories recovered from streak canal and quarter foremilk samples showed a contemporaneous association (identity).
n=1) were recovered simultaneously from streak canal and quarter foremilk samples of 20 buffaloes.
Of the 80 streak canal swab samples each of cow and buffalo collected in the first two months of the lactation, 73 (91.
The higher prevalence of streak canal infections both in cows and buffaloes in the present study than that reported by this worker may partly be explained on the following grounds: a) Muhammad (1992) reported only staphylococcal infections; infections by other microorganisms which might have infected streak canal were disregarded.
