That's part of what's interesting (and maybe provable) from a research standpoint -- that different "clients" would seek bio-weapons to target certain populations. With Lyme and fatiguing diseases, the speculation is that release of the bugs (literally ticks) was unintentional. But I can easily imagine that in a research environment, any specific targeting mechanisms (ethnic/gender/etc) would be very key to figuring out how the bugs behave and what value they'd be. And further, what defensive measures can be taken to mitigate an outbreak:

Experimental Ebola Serum Likely Treating Sick Americans
An American doctor working in West Africa and another health care worker, also American, who contracted Ebola there have both received experimental treatments for the deadly viral disease, according to news reports.
Nancy Writebol, a worker with the charity Samaritan's Purse, received an experimental serum, and Dr. Kent Brantly, from the same charity, received a blood transfusion from a patient who recovered from Ebola, according to NBC News. One or both of the health care workers are also being flown to an isolation unit in an American hospital for treatment, according to news reports.
Though there are conflicting reports, and no one is saying exactly what the experimental serum is, its likely that both of the reported methods contained antibodies to the Ebola virus, said Dr. William Schaffner, a professor of preventive medicine and infectious diseases at Vanderbilt University Medical Center in Nashville, Tenn. Delivering antibodies to a patient could slow the virus's replication, and give the immune system time to recover.
Diseases That Just Won't Quit
"There is a long tradition of using immune serum as treatment," Schaffner told Live Science. "You give the person antibodies, and you would hope that those antibodies would then bind the viruses and interfere with their multiplication."
No current treatments
This Ebola outbreak is the largest in history and has so far claimed 729 lives in Sierra Leone, Guinea and Liberia. Doctors without Borders has said that the crisis is "out of control." Sierra Leone has declared a national emergency, closed all of its schools and is quarantining disease hot spots. [2014 Ebola Outbreak (Infographic)]
There are no treatments or vaccines available for Ebola, though several are in the pipeline. A study in Nature this year reported that one drug improved survival in monkeys who were exposed to a closely related virus, called Marburg virus. Public Health Canada is testing another antibody-based treatment and the company Tekmira Pharmaceuticals has developed an experimental drug that uses a process called RNA interference to block the virus' replication, Forbes reported.
