Concept explainers

Viral Infections

Viruses are abundantly found, minute entities that have genetic material enclosed within a protein coat. The proteinaceous material enclosing the genetic material of the virus is called a capsid. The genetic material could be either DNA (deoxyribonucleic acid) or RNA (ribonucleic acid). A virus is too minute to be looked at with naked eyes and therefore visualized with the help of a microscope. They are acellular entities that require a host for processes, such as replication, transcription, translation and multiplication. Plants, animals, and bacteria act as host wherein the virus reproduce. Viruses cannot multiply outside the host's body and thus are considered nonliving outside the host body.

As an illustration, a patient undergoing a laparoscopic-assisted vaginal hysterectomy (LAVH) procedure under general anesthesia might be happier not to know the numbers of portals of entry for potential transmission of pathogenic microbes to which she will be subjected. The anesthesia provider would be accessing the patients airway and vascular system by an IV line. Which portals of entry will the surgeon be accessing?

Which of the following is not a good portal for entry for a pathogen? A) Nasal cavity B) Skin C) Urinary tract D) Mucous membranes E) Muscle
Clostridium difficile infection is the leading causeof hospital-associated gastrointestinal illness. It is typicallytreated with a course of antibiotics, but the infection recursin about 20% of cases. C. difficile infections are difficult toeradicate because the bacteria exist in two forms: a repli-cating, toxin-producing form and a spore form that is resis-tant to antibiotics. Fecal microbiota transplantation—thetransfer of normal gut microbiota from a healthy individ-ual—can resolve >90% of recurrent infections, a much bet-ter cure rate than further antibiotic treatment alone. Whydo you suppose microbiota transplantation is so effective?
As microbes come in contact with humans there are variables that come into play determining if the microbe will cause infection, colonize onto the host without any issues or is removed by the hosts immune system. Microbes that become associated with us and don't cause any issues should be a benefit and provide us with something useful (i.e. vitamin or prevent colonization of other microbes). Please research a microbe that is normally associated with us, considered a normal flora, and provides a benefit. Answer each of the following about the microbe you choose. 1. Scientific name of the microbe. 2. Where it is normally found on/in the human body? 3. What is the benefit/advantage the microbe provides to us? Explain in 3-4 sentences. 4. An interesting fact about the microbe not related to the benefit/advantage. 5. Can this microbe cause disease in its human host? Explain why or why not in a few sentences.
