Cefazolin works by stopping bacteria from making cell walls, which eventually causes the bacteria to die.

Portland has four distinct seasons, but none of them are extreme. Summer weather really starts in July and ends in September. Summer temperatures average around 80 degrees but do go over a 100 for one or two days a year. Overnight temperatures average around 60 degrees. This is a 90 day period that typically has very little (and sometimes none) rain. The summer is really one of the best parts about Portland.
