Boston, Massachusetts — When thousands of experimental biology researchers gather in Boston this weekend, many of them undoubtedly will be presenting work related to the hunt for the next generation of antibiotics and how to battle back existing and emerging superbugs. For one scientist from the Texas Rio Grande Valley, it's not about what the research of tomorrow holds, it's about the kind of action the people in communities like his need today.

Subburaj Kannan, an instructor of microbiology at Southwest Texas Junior College, is passionate when he talks about how antibiotic resistance is affecting patients in Eagle Pass, Texas, a town with a population of 26,000 just across the border from Mexico's Piedras Negras.

Despite enactment of laws intended to stem the tide of antibiotics from Mexico, the drugs remain relatively easy to acquire and commonly are shared among relatives and neighbors. On top of that, many residents aren't fully aware of the consequences of not taking antibiotics as directed by a physician and of taking antibiotics for nonbacterial infections. Together, these factors likely are creating conditions just right for the emergence of antibiotic-resistant microbes.

" In South Texas, you can walk across the bridge into Mexico and buy medicine in a different manner than in the United States. In the US, you need to get a prescription from the doctor and take it to the pharmacy where they check the insurance coverage, then give you the medicine," Kannan explains. "But, if you walk across the bridge, what you want is your call. You can buy any medicine with limited restrictions."

Complicating matters is that uninsured people who come down with a cold or the flu simply want to get their hands on something that will make them feel better. "Whatever medicine comes close to them, they take," Kannan says. "Due to limited knowledge and the lack of access to the appropriate health care, a considerable portion of the border community utilizes medications - whether it's antibiotic, antiviral, or anti-parasitic - to get better. Especially antibiotics," he emphasizes.

Eventually, he says, if the misuse of antibiotics continues at this pace, "we won't have any effective antibiotics for clinical treatment. If we don't have the proper medicine, meaning antibiotics, it can lead to the wide-ranging spread of infectious diseases in the general population. It can go across states and all across the globe. If we don't have the proper tools to combat infectious diseases, secondary illness, such as organ failure, respiratory system failure, and cardiovascular arrest can develop."

Kannan, who is collaborating with officials at the Fort Duncan Regional Medical Center, the Texas Commission on Environmental Quality, the US Department of Agriculture, and other institutions, will present on Sunday a preliminary outreach model that he hopes could help mitigate antimicrobial resistance in his community and others.

Message Will be Two-Fold

"The focus of this presentation will be that the government and the nongovernmental agencies should take this issue as seriously as they do global warming, abortion, or pornography. They think those topics are so hot and of public interest," he says. "This is a far more serious issue than any other topic in this day and age."

Secondly, he says, "the goal is to get the message out that, yes, it is possible for the nonmedical community to generate awareness in the general public about how serious this problem really is."

Kannan's poster presentation will include potential strategies for preventing antimicrobial resistance in health care settings, offer ideas for partnerships with organizations not usually recruited for public-health campaigns, and suggest seemingly untraditional venues for this kind of outreach, such as casinos, beaches, and churches.
