Neisseria gonorrhoeae Introduction Neisseria gonorrhoeae is the obligate human pathogen that causes the sexually transmitted disease (STD) gonorrhea. This Gram-negative diplococci/gonococci does not infect other animals or experimental animals and does not survive freely in the environment. The gonococcal infection occurs in the upper or lower tract, pharynx, ophthalmic area, rectum, and bloodstream. During the 1980’s gonorrhea was also referred to as “the clap” when public awareness was quite
Neisseria gonorrhoeae is a fastidious Gram-negative cocci that require nutrient supplementation to grow in laboratory cultures, they grow on chocolate agar with carbon dioxide (www.wikipedia.com, 2016). A German physician by the name of Albert Ludwig Sigesmund Neisser subsequently undertook research on a skin infection called leprosy, which lead him to later discover syphilis and gonorrhea. The bacterium neisseria gonorrhoeae became known in 1879 after Neisser identified the coffee bean shaped diplococci
venereal disease to their infant during childbirth. Both genders are susceptible to gonorrhea. Gonorrhea is caused by Neisseria gonorrhoeae. Neisseria gonorrhoeae is a bacteria that grows and multiplies easily in the humid areas of the reproductive tract. The bacteria can develop in the cervix, uterus, and fallopian tubes of a woman and the urethra in both men and women. Neisseria
leading cause of the disease Gonorrhea is the proliferation of the bacteria Neisseria gonorrhoeae, also known as gonococci or gonococcus. This bacterium is a gram-negative diplococcus, meaning it has a thin peptidogylcan layer in its cell wall and it is spherical in shape and found in pairs. The organism is usually found in the cell in a phagocytic leukocyte, with various nuclei shapes. Because the bacteria Neisseria gonorrhoeae is found within a phagocytic white blood cell, it is unknown whether or
Gonorrhoea are fastidious gram-negative, facultative, intracellular and typically appear in pairs (diplococci), in the shape of coffee beans. Among various species of Neisseria that colonize humans, only N. gonorrhoeae is clinically important responsible for transmission through sexual contact (Elias J et al., 2011).They are non-motile, aerobic, capnophilic, non-sporulating, possess pilli to adhere the surfaces of mucous membrane of warm blooded hosts (Janda Wet et al., 2007). The type IV pili (Biais
for the bacterium gonorrhea is Neisseria gonorrhoeae, also known as gonococci or gonococcus. It is a species of gram-negative spherical-shaped diplococci bacteria that is responsible for this disease. It is usually seen in pairs with neighboring sides flattened. The organism is usually found in the cell in a particular category of white blood cells with various shapes of nuclei, of the gonorrhea pustule exudates with humans as its only natural host. N. gonorrhoeae is highly efficient in using
but scientists are working on a vaccine that the population could take at a young age to build a defense against the bacteria (Kollar et al., 2005). However, the difficulty in designing this drug is in the bacteria’s methods of resistance. Neisseria gonorrhoeae can change both its phenotype and genotype, and it can produce its own antigens, making it difficult for one antibiotic to target and destroy all types of the bacteria (Kollar et al.,
Gonorrhea is one of many highly contagious sexually transmitted infections caused by the bacteria Neisseria gonorrhoeae, a gram-negative intracellular diplococcus. These infectious bacteria can spread through sexual contact and intercourse, as well as transmission during childbirth from mother to fetus. This specific bacterium likes to grow in warm, moist areas of the body. They can multiply very fast and infect the mucous membranes. Gonorrhea is said to infect an approximate 820,000 people in the
together with a red base. • In rare occasions, C. trachomatis causes a syndrome called reactive arthritis - conjunctivitis, arthritis (typically sacroiliitis), and urethritis. • The most common organisms responsible for urethritis include Neisseria gonorrhoeae, Chlamydia trachomatis, and Mycoplasma genitalium. • Urethritis is less commonly caused by herpes simplex virus (HSV) or Trichomonas vaginalis infection. All of these are sexually transmitted
Neisseria gonorrhoeae, commonly known as gonorrhea, is a gram-negative bacteria found in the family Neisseriaceae. This proteobacteria does not form spores, cannot move (have no flagellum), are encapsulated in a bacterial capsule, and are non-acid fast. They are diplococci, found in pairs of round kidney-bean shaped bacteria. They are small, smooth and colourless with flattened sides. These obligate aerobes need oxygen, carbon dioxide, and other nutrient supplementation (usually chocolate agar) to
