Enterovirus-D68 (EV-D68) is a virus that can cause mild to severe respiratory symptoms, especially in children. Since 1987, small numbers of EV-D68 cases in the US have been reported regularly to CDC. The number of people with new, confirmed EV-D68 infection was much greater in 2014 than that reported in previous years. The term that best describes the status of EV-D68 in 2014 is

Case study #3 Dental caries (dental decay) is the result of solubilization (dissolving) of tooth enamel by acid. The microbes associated with cavities, usually the Gram-positive Streptococcus mutans and Lactobacillus species living in biofilms as plaque, produce organic acids as the waste product of a specific metabolic pathway. Regular tooth brushing and chewing gum after meals, which increases saliva production, and are the two leading methods that can be preformed daily to prevent tooth decay.   The increased saliva production is a mechanical defense that is triggered by chewing gum. This is part of

Case study #4 Plasmodium falciparum is the most virulent causative agent of malaria. This parasite has a trophozoite form that must undergo a life cycle within the gut of the female Anopheles mosquito to be naturally transmitted to the next host. The parasite also has separate trophozoite forms in the liver and blood of humans. If the malaria parasite is introduced into a pregnant woman, it can cross the placental barrier and infect the developing fetus. People at increased risk for malaria infection are children under 5 years old, pregnant women, and people with AIDS (active HIV infection).   Defend your answer to the previous question – why or why not would chloramphenicol, which binds to the 50S ribosomal subunit, be effective at treating a P. falciparum infection?
