The Yellow Menace

As microbes start to learn defying the science behind antimicrobials, more superbugs are noted more and more. Let's look on what happens with superbug 'Streptococcus aureus.'

THIS minute, “bundle of grapes-looking” bacteria naturally resides on the mucous membranes of the body and on the human skin. Staphylococcus aureus (aureus is Latin for “yellow”) is present in around a third of any human population, with 20 percent being long-term carriers of this silent menace.

And it is very adaptable to antibiotic threats. Being so, it is one of the five most common causes of nosocomial infections, those diseases that we got for getting so sick and hospitalized.

The first cases of resistance to penicillin, the groundbreaking discovery of Alexander Fleming in 1928, appeared in 1947 (four years after mass production started in 1943).

So methicillin became the antibiotic of choice. But then reports of significant toxic effects on the kidney came out. Methicillin-resistant Staphylococcus aureus then appeared (first detected in Great Britain in 1961). Since then the phenomenon became common in hospitals.

Oxacillin came out to take up the cudgels. But then new waves of resistant strains appeared. Half of all Aureus infections in the United States, for instance, are resistant to penicillin, methicillin, tetracycline and erythromycin, so that... [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...

Death By Heat Stroke in the Philippines

The hotter and earlier-onset El Niño phenomenon this year 2010 poses a threat to the Filipino lives. How much life it took? See incidence that reached the news.

Although rushed to the hospital immediately, he died shortly afterwards (around 11 a.m.) due to heat stroke. That day Isabela peaked at 38.2 degrees Celsius. Sixteen others were rushed to the hospital for dehydration and heat exhaustion. (Check report ) On 28 April 2010, a veteran Cavite cop, PO3 Florencio Gamana Alivio (48), succumbed to cardiac arrest as a result to heatstroke while having tae bo with his colleagues at the Cavite Police Provincial Office (CPPO) grounds in Camp General Pantaleon.
