Furthermore it was reported that these strains pose a zoonotic risk because they could be transferred directly from birds to humans or serve as a genetic pool for ExPEC strains.
Given the these reassorted strains pose the greatest risk to human and animal health and have been responsible for all past human pandemics of the 20th and 21st centuries, the ability to rapidly and reliably establish the origins and evolutionary history of such strains at a molecular level is of paramount importance.
Given that these strains pose the greatest risk to human and animal health and have been responsible for all human pandemics of the 20th and 21st centuries, there is a vital need for the origins and evolutionary history of these strains to be rapidly established.
Fluoroquinolone-resistant Campylobacter strains pose a significant public health threat in the United States.
These strains pose a pandemic threat if they become capable of being transmitted efficiently from person to person and if limited protective immunity exists in the human population.
Whether these strains pose a major threat to human health in light of the low livestock density and continued spread of epidemic hospital and community strains of MRSA in Canada remains unknown.
The emergence and transmission of drug-resistant M. tuberculosis strains, especially Multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains pose significant clinical, economic, as well as societal challenges.
Furthermore, new communicable diseases have emerged: HIV/AIDS prevalence has been steadily increasing over the last two decades and epidemics such as H1N1 with genetically evolved strains pose specific periodic risks.
Vaccination with M2, with key sequences represented, may provide broad protection against influenza A. Yearly development of influenza vaccines that are antigenically matched to circulating strains pose extraordinary challenges.
Emergent highly pathogenic H5N1 and H7N9 avian influenza A strains pose a continuing danger to the human population, particularly as they have very high mortality rates (>60%) (45, 60).
Health officials said the strain posed no serious threat to humans.
