Hi, My niece has been diagnosed with klebsiella pneumoniae, she is 32 weeks pregnant with her 3rd child and is an insulin dependant diabetic, she has a UTI a severe cough and mastitis, and has been admitted to the local maternity unit so that they can treat the infection, I would like to know if her other 2 children need to be tested for klebsiella pneumoniae, as they also have severe coughs but also have colds?
