MARKET DRIVERS
Bacteria represent the essential class of micro-organisms that play a crucial role in the development of infection of any disease in human beings and animals. They are classified into two types on the basis of gram staining test, viz., gram-positive bacteria and gram-negative bacteria. Neisseria is one of the most important classes of bacteria that form colonies on the mucosal surfaces of animals. Neisseria comprises 11 species, of which two are pathogenic and others are harmless. These belong to the gram-negative class of bacteria because these species show a negative response to the gram test.
As per the U.S. Centers for Disease Control and Prevention (CDC), more than 300,000 new cases of gonorrhea were reported in the U.S. in 2012, an enhancement of around 4% in contrast to 2011. Therefore, such a rising prevalence of infections is an important growth driver of the market. Further, due to extensive R&D practices, a number of drugs and formulations are on the way to entering the market during the forecast period. Some of the important pipeline products include AXD0914, Cribrostatin-6, SM-295291, and SM-369926 amongst numerous others. In addition, owing to the rising incidences of homosexuality and bisexuality, the threat of gonorrhea has also increased. These factors are aided by rising awareness regarding infections and diseases and rising medical expenditure. Due to these, the market is anticipated to grow at a steady rate.
On the other hand, factors such as government austerity, high cost of treatment and R&D, and ignorance towards the symptoms may hamper the growth of the market to a certain extent.
