MRSA is also common in infections of dogs and cats and transmission to humans can occur, since pet owners hug and kiss their pets or let them sleep in their beds. [116] While sharing of isolates can occur, infections in humans seem to originate from HA-MRSA rather than from pet-acquired CA-MRSA. [117]
The overuse of fluoroquinolone and other antibiotics fuels antibiotic resistance in bacteria, which can inhibit the treatment of antibiotic-resistant infections. [ 27 ] [ 28 ] [ 29 ] Their excessive use in children with otitis media has given rise to a breed of bacteria resistant to antibiotics entirely. [ 30 ]
Cefalexin is not effective against infections caused by methicillin-resistant Staphylococcus aureus (MRSA), most Enterococcus, or Pseudomonas. [4] Like other antibiotics, cefalexin cannot treat viral infections, such as the flu, common cold or acute bronchitis. [4] Cefalexin can be used in those who have mild or moderate allergies to penicillin ...
Resistance to these antibiotics has also led to the use of new, broad-spectrum anti-Gram-positive antibiotics, such as linezolid, because of its availability as an oral drug. First-line treatment for serious invasive infections due to MRSA is currently glycopeptide antibiotics (vancomycin and teicoplanin). A number of problems with these ...
Farmers typically use antibiotics in animal feed to improve growth rates and prevent infections. However, this is illogical as antibiotics are used to treat infections and not prevent infections. 80% of antibiotic use in the U.S. is for agricultural purposes and about 70% of these are medically important.

Cephalosporins can be indicated for the prophylaxis and treatment of infections caused by bacteria susceptible to this particular form of antibiotic. First-generation cephalosporins are active predominantly against Gram-positive bacteria, such as Staphylococcus and Streptococcus. [7]
The strain has become the dominant type of MRSA in European livestock, probably due to widespread antibiotic use in pig farming, researchers say. Highly antibiotic-resistant MRSA strain that arose ...
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.
