Summary: | Previous research conducted in our laboratory found a significant prevalence of multi-drug resistant (MDR)
Salmonella
and MDR
Escherichia coli
(MDR EC) in dairy calves and suggests that the MDR EC population may be an important reservoir for resistance elements that could potentially transfer to
Salmonella
. Therefore, the objective of the current research was to determine if resistance transfers from MDR EC to susceptible strains of inoculated
Salmonella
. The experiment utilized Holstein calves (approximately 3 weeks old) naturally colonized with MDR EC and fecal culture negative for
Salmonella
. Fecal samples were collected for culture of
Salmonella
and MDR EC throughout the experiment following experimental inoculation with the susceptible
Salmonella
strains. Results initially suggested that resistance did transfer from the MDR
E
.
coli
to the inoculated strains of
Salmonella
, with these stains demonstrating resistance to multiple antibiotics following in vivo exposure to MDR EC. However, serogrouping and serotyping results from a portion of the
Salmonella
isolates recovered from the calves post-challenge, identified two new strains of
Salmonella
; therefore transfer of resistance was not demonstrated under these experimental conditions. |
