Can lactose fermenter and enterobacter cause infection after hip replacement?

Yes, lactose fermenters, such as certain strains of Escherichia coli, and Enterobacter species can cause infections following hip replacement surgery. These bacteria can be part of the normal flora but may enter the surgical site or bloodstream, particularly if there are breaches in sterile technique or compromised immunity. Infections may lead to complications such as prosthetic joint infection, which can require further surgical intervention and antibiotic treatment. Prompt identification and management of such infections are crucial for successful recovery.
