However, some adhesins (sfa/foc, papGIII), some toxins (hlyC, cnf1), and iroN were significantly overrepresented in pneumonia E.
In our study (Figure 1), pneumonia isolates differed from bacteremia isolates because they significantly more often carried sfa/foc, iroN (both belonging to PAI III), papGIII and cnf1 (belonging to PAI II), and hlyC (belonging to PAI I and II).
Indeed, virulence and antimicrobial-drug resistance were both higher in pneumonia isolates than in commensal isolates and the following were more highly represented: sfa/foc, papC, papGIII, fyuA, iroN, hlyC, and cnf1.

It is worth noting that, among the 16 VFs detected in phylogroup B2, two were exclusive to that group (sfaDEand cnf1), and six others (papC, irp2, kpsMT II, hlyA, ompT, and chuA) showed a statistically significant association (P [less than or equal to] 0.001) with that group (Table 1).
On the contrary, the VFs hlyA, sfaDE, cnf1, and ibe10 have been reported in higher frequencies, and cvaC and iss in lower frequencies than those found in this study (10,12,13).
In the present study, seven dogs (4.5%) were positive for strains containing cnf1, including one hybrid strain with eae and cnf1.
NTEC positive for cnf1 were also identified and were mostly in phylogroups B2 and D, which are associated with ExPEC.

We also describe in detail seven toxins: Staphylococcus aureus [Alpha]-toxin, Shiga toxin (Stx), cytotoxic necrotizing factor type 1 (CNF1), E.
CNF1, CNF2, and the dermonecrotic toxins from Bordetella species form a unique subset in this family, since these toxins have the capacity to activate Rho (Figure 1 C) (29-32).
