Use of MAbs to detect the presence of virulence factors in L. monocytogenes channel catfish isolates and correlation with pathogenicity
L. monocytogenes catfish isolatea | Serovar | LLO | PC-PLC | Pathogenicityb |
---|---|---|---|---|
ATCC 15313 | 1 | − | + | − |

CCF1 | 1 | + | + | + |
CCF4 | 4 | − | − | − |
HCC7 | 1 | +c | + | + |
HCC23 | 4 | + | − | − |
CCF, channel catfish fillet; HCC, healthy channel catfish organs.
Pathogenicity data for CCF1, CCF4, HCC7, and HCC23 have not been published.
HCC7 is weakly positive for LLO.
