The Bloody Scourge

One of the deadly genera of bacteria that have mutating strains making invulnerable to common antibiotics is the scourge of the blood. Discover which microorganism it is.

“BLOOD smelled much the same, whatever the source,” wrote David Hewson in his first book, The Seventh Sacrament (2007).

The Group-A Streptococci (chainlike circles) are known among laboratory scientists for its unique ability to burst the red blood cells. And to this bloody scourges Streptococcus pyogenes belongs.

If you had a strep throat or sore throat recently, Pyogenes caused that. It is a mild infection in the leagues of impetigo, erysipelas, and cellulitis.

But Pyogenes can be life-threatening when it causes “necrotizing fasciitis,” a rare infection of the deeper layers of the skin. It is commonly known as “flesh-eating disease” for the obvious reason that the affected tissues simply turn violet (blisters may appear afterwards) and then die away. As high as 73 percent of patients with this disease die if left untreated.

It is not that Pyogenes “eats” the tissues for meals. But that it... [READ MORE]

Deadly X-Gene Mutants

A RECENT study on macrophages (i.e. defensive cells in our body that engulf threatening substances inside our body) introduced me to a lethal, genetic disease that targets the male population. This disease is called Duchenne muscular dystrophy (DMD), named after the French neurologist Guillaume Benjamin Amand Duchenne, who described it in 1861. While it has an incidence of one in 3,500 newborn males, health experts consider this as the most common lethal disease of childhood around the world. Mutation in the male (X) chromosome [dystrophin gene, locus Xp21] causes a rapid degeneration of the muscles, leading into an eventual loss of walking ability and then death. While females do not exhibit symptoms, they can be carriers of these defective genes, especially if the father had this condition or the mother is also a carrier. Symptoms usually appear before age five; at times visible in early infancy. These symptoms involve... ( Read more .) This article appears in Sun-Star Ce...

Joy, Temperance and Repose

“I RECKON being ill as one of the great pleasures of life, provided one is not too ill and is not obliged to work till one is better,” wrote Samuel Butler in The Way of All Flesh (1903). The term “antioxidant” was originally used in the 18th century to refer to a chemical that prevents the consumption of oxygen in laboratory experiments. However, in the late 19th and early 20th century, extensive study exploded... ( Read more ) This article appeared in SunStar Cebu newspaper on 02 June 2010.
