Pseudomonas Aeruginosa: The Air-Breathing Troublemaker

One of the most dangerous super-bug today is Pseudomonas aeruginosa. And like any superbug available antibiotics today fails to work against its new strains. Knowing these bacteria allows you to be more careful in environments or places where these troublemakers about, and statistically infects people.

THE bacteria Pseudomonas aeruginosa (PA) normally resides in soil, water, skin flora, and man-made environments. It can be found regularly on the surfaces of plants, and occasionally, of animals. It is one of the most vigorous, fast-swimming bacteria seen in hay infusions and pond water samples. It is a stranger to the internal parts of the human body, though.

Characteristically PA needs minimal nutrition. It is even often observed growing in distilled water. It grows optimally at room temperature. And it has predilection to grow in moist environments, thriving on biofilms.

Still it is opportunistic. It exploits certain break in the human defenses to initiate infection. In fact, PA almost never infects uncompromised tissues. But if the defenses break down, it can infect almost any part of the body.

Because of that unnatural virulence, PA can cause... [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.
