Summary Introduction

Laboratory-associated infections (LAIs) are also known as laboratory-acquired infections or occupational illness. LAIs may arise in clinical laboratories, animal facilities, and also in production installations. LAIs are of community health concern, as an infected worker may transmit the infection to his relatives, colleagues, and family members. In the United States (U.S) about 500,000 laboratory workers are at risk of exposure to contagious agents, which may cause diseases that vary from mild to life-threatening infections.

What are “healthcare-associated infections” (HAI)and how are they acquired? What problems can theycause?
Discuss both persistent and transforming infections.
Q. Because you love to work with children, you accept a job offer at a local pediatric clinic. A concerned mother brings herdaughter who had eye infection (pink eye, caused by gram-negative bacteria). The doctor prescribes her Cephalosporinantimicrobial drug. After a few days, the mother returned to the clinic and complained that the medicine did not help herdaughter. This time, the physician prescribes Penicillin antimicrobial drugs. However, based on your knowledge inmicrobiology class answer:1) why Cephalosporins does not eliminate the bacteria? 2) why do you think the Penicillin antimicrobial drugs will not help the little girl, and the physician should prescribe aStreptomycin antimicrobial drug as eye drops? 3) If the same bacteria develop resistance to Streptomycin, describe the bacteria's possible resistance method against thisantimicrobial drug?
