In the period October 1980-May 1981, 5 young men, all active homosexuals, were treated for biopsy-confirmed Pneumocystis carinii pneumonia at 3 different hospitals in Los Angeles, California. Two of the patients died. All 5 patients had laboratory-confirmed previous or current cytomegalovirus (CMV) infection and candidal mucosal infection. Case reports of these patients follow.
Last week, the State Department performed a small but smart gesture towards countering the continued outbreak of the Ebola virus in West Africa by releasing a video featuring President Barack Obama speaking to the people of Liberia, Sierra Leone, Guinea, and Nigeria.
This may come as a total shock, but pure forms of illicit drugs can be hard to come by. Certain controlled substances are frequently adulterated, if not outright contaminated, by products that range from the household to the industrial to the pharmaceutical. Of course, some substances are more easily, frequently, and profitably adulterated than others: cocaine purchased on the retail level is on average 31%, well, not cocaine, while the purity of heroin on the street is even lower, resting around 65% (1).
Unbeknownst to many of the public, August was National Immunization Awareness Month. I know, I know: it’s been overshadowed by some very exotic and thrilling headliners this month. The Ebola epidemic blazing defiantly in West Africa. The jaw-dropping videos shown on Discovery Channel’s “Shark Week.” The ALS Ice Bucket Challenge clogging everyone’s social feeds. Vaccines are just not as sexy or as flamboyant as these issues. Truthfully, they’re a bit dull to talk about, not a topic you would tend to bring up at cocktail parties or at the water cooler.

In the twentieth century, men toiling in British and American coal mines relied on a primitive alert system for imperceptible dangers: the bright canary bird. Miners toted the caged birds into the depths of the earth to serve as early warnings against poisonous and potentially fatal gas leaks. If the tiny birds suddenly slumped in their cages due to the presence of odorless and colorless carbon monoxide, miners would beat a hasty retreat to safer, cleaner air.
Many pitfalls await the undergraduate in the laboratory. Bunsen burners! Liquid nitrogen! The slack work ethic of one’s peers! The dreaded group projects! But the most common risk budding researchers face are the rubber glove-donners themselves, perpetrator and victim rolled into one lab coat-wearing pipetter, armed and often dangerous with great knowledge but little know-how.
Medicine is an imperfect science, its history shot through with barbaric and dubious practices from grave robbing to bloodletting. Since even before the time of that father of modern medicine, it can seem that physicians have more often violated Hippocrates’ decree “above all, do no harm” than abided by it.
“Water-borne pathogen.” Three gut-twisting words with enough power to make any epidemiologist, public health official, or globetrotting tourist double over. One of the most common forms of disease transmission is the microbial hijacking of our most precious fluid. This mechanism of infection is employed by a motley crew of microscopic organisms that have adapted to prey upon our unquenchable thirst, from pervasive bacteria like cholera and typhoid to often less famous but no less formidable parasites such as giardia and dracunculiasis.
Ask any political scientist: regime change has unforeseen consequences. The vacuum left in the wake of a collapsing leadership and the disorganization that follows, whether greeted with joy in the case of liberation or fear in the case of tyranny, brings unexpected change. For the central Asian states of the former Soviet Union in the early 1990s, among these aftereffects was the appearance of a curious and frightful little worm that saw, in the collapse of the monolithic political powerhouse, a bright opportunity for itself.
Microbial Misadventures is a recurring series on Body Horrors looking at instances and incidents where human meets microbe in novel and unusual circumstances that challenge our assumptions about how infections are spread.
Shout “fire” in a crowded room and watch the occupants fly for the exits. Speak the word “malaria” and watch as all within earshot reach for the nearest can of DEET. The incontrovertible fact of malaria’s relationship with mosquitos is one that has been known since Sir Ronald Ross discovered the parasite nesting within the belly of a mosquito in 1897. Such is the natural order, an incontestable necessity of the protozoan parasite’s life cycle. Humans, however, are rather adept at bucking that system – see cronuts, labradoodles, and the college bowl ranking system for examples. Also due to the interference of mankind, as a 1995 Taiwanese medical mystery proved, malaria can indeed be spread without the assistance of their obnoxious arthropod cronies.
