World Health Organisation has released the list of 12 most deadly superbugs. According to WHO report, these drug-resistant superbugs pose threat to humans.

The WHO states that these superbugs are resistant to drugs because of overuse of antibiotics by humans. Britain’s chief medical officer Sally Davies has compared the threat from the superbugs to terrorism.

The 12 deadly superbugs have been selected on the basis of their resistance to drugs, the number of deaths they caused, the frequency at which people get infected and the fact that knowledge about them needs to be further explored.

Take a look at them.

 Acinetobacter baumannii

Acinetobacter baumannii is an opportunistic pathogen in humans, and it affects the immune system directly. This superbug is resistant to carbapenem antibiotic. Carbapenems are used for treatment of infections which are caused by multi-drug resistant (MDR) bacteria.

 Pseudomonas aeruginosa

Pseudomonas aeruginosa is a pathogen which is associated with infections caused by toxins in the body. But these bacteria are also carbapenem-resistant due to excessive use of the drug in hospitals.

Enterobacteriaceae

They are also called carbapenem-resistant EnterobacteriaceaeThis is because they are resistant to carbapenem category of drugs.

 Enterococcus faecium

Enterococcus faecium is a non-hemolytic bacterium in genus Enterococcus. They are resistant to antibiotic vancomycin. This antibiotic is used to treat an infection of intestines.

Staphylococcus aureus

Staphylococcus aureus is round-shaped bacterium which is found in respiratory tract and nose. It is resistant to two antibiotics called vancomycin and methicillin.

Helicobacter pylori

Helicobacter pylori is a bacterium found in the stomach. These bacteria are responsible for ulcers. They are resistant to clarithromycin antibiotic, which is used to treat bacterial infections.

 Salmonellae

Salmonellae is a rod-shaped bacterium, and it is caused due to contamination of food. It is also fluoroquinolone-resistant.

Neisseria gonorrhoeae

It is also known as gonococci and is responsible for sexually transmitted infection called gonorrhoea. They are cephalosporin-resistant. Cephalosporin is an antibiotic which is used to treat different infections in the body.

Streptococcus pneumoniae

Streptococcus pneumoniae is an alpha and beta hemolytic member of genus Streptococcus. It is recognised as a primary cause of pneumonia. This bacteria is resistant to penicillin group of antibiotics.

Haemophilus influenzae

Haemophilus influenzae is a gram-negative bacterium and is responsible for wide range of localised and invasive infections. This bacterium is ampicillin-resistant, which treats respiratory infections.

Shigella

Shigella is a facultative anaerobic bacterium that causes dysentery, diarrhoea with blood. This bacterium is also fluoroquinolone-resistant.
