Experimental Inoculation of BFDV-Positive Budgerigars (Melopsittacus undulatus) with Two Mycobacterium avium subsp. avium Isolates

Table 4

Occurrence of M. avium positive samples.

Group	Crop swab	Cloacal swab
P	0.019^1	0.154^b2
Ph	0.000	0.136^b
K	0.000	0.000^a

1Crop swabs for M. avium were not analyzed because of too few positive samples in the experiment (for the two groups, K and Ph, M. avium was not detected at all, and for C it was detected in only a few samples).
²The different letters in the column represent a different mean share of the positive samples for birds within the two corresponding groups.
