What Is A Virus? What Is A Viral Infection?
A virus (from the Latin virus meaning toxin or poison) is a microscopic organism consisting of genetic material (RNA or DNA) surrounded by a protein, lipid (fat), or glycoprotein coat. Viruses are unique organisms because they cannot reproduce without a host cell. After contacting a host cell, a virus will insert genetic material into the host and take over the host"s functions. The cell, now infected, continues to reproduce, but it reproduces more viral protein and genetic material instead of its usual products. It is this process that earns viruses the classification of "parasite".

HIV Testing Kits To Be Distributed To Residents In Washington, D.C., This Week
On Wednesday, a national HIV testing campaign called "Don"t?Guess?Test!" is making a "controversial move" by distributing free HIV testing kits that have not been approved by FDA in the lead up to National HIV Testing Day on June 27, the Washington Business Journal reports. The kits have been clinically tested and are available in Africa, Asia and Europe, according to the Business Journal. Due to the sensitive nature of the non-FDA-approved kits, campaign officials are not disclosing how many tests will be distributed or the location of distribution at this time (Plumb, Washington Business Journal, 6/22).

Carbapenems And Other Agents That Provide Broad-Spectrum Activity Are Preferred By Surveyed Physicians For The Treatment Of Intra-Abdominal Infections

Arlington Medical Res (AMR) and Decision Res find that surveyed physicians will increase prescribing of Wyeth"s Tygacil, Merck"s Invanz and Johnson & Johnson"s Doribax in the next five years for the treatment of intra-abdominal infections because of their potent broad-spectrum activity and efficacy against gram-negative and anaerobic organisms. "Treatment for intra-abdominal infections is largely empiric," stated Lisa Arias, analyst at Decision Res. "A variety of organisms, particularly gram-negative aerobic bacteria and anaerobes, are documented in patients with an intra-abdominal infection. In fact, the leading attribute that physicians surveyed look for in a drug to treat intra-abdominal infections is its activity against anaerobes." The new report entitled Hospital Anti-Infectives Insight Series: Intra-Abdominal Infections also finds that 96 percent of surveyed physicians cite a drug"s activity against anaerobes as the leading attribute in antibiotic selection. Intra-abdominal infections are often polymicrobial in nature and involve anaerobes specific to the etiology of the infection, so activity against these organisms is advantageous even without bacterial confirmation. "Physicians also rank availability in intravenous formulation and a low propensity to induce resistance as other important drug attributes that influence their selection in antibiotics," added Ms. Arias. "While some agents with anaerobic and gram negative activity, such as carbapenems, address some of these attributes, no antibiotic captures all of the top most important attributes which leaves opportunity for novel products to differentiate themselves."
