Diagnosis is through culture, Gram stain, or nucleic acid tests, such as polymerase chain reaction, of a urine sample, urethral swab, or cervical swab. Chlamydia co-testing and testing for other STIs is recommended due to high rates of co-infection. Microbiology
Neisseria species are fastidious, Gram-negative cocci that require nutrient supplementation to grow in laboratory cultures. Neisseria spp. are facultatively intracellular and typically appear in pairs (diplococci), resembling the shape of coffee beans. Neisseria is non-spore-forming, capable of moving using twitching motility, and an obligate aerobe (requires oxygen to grow). Of the 11 species of Neisseria that colonize humans, only two are pathogens. N. gonorrhoeae is the causative agent of gonorrhea and N. meningitidis is one cause of bacterial meningitis. Culture and identification
N. gonorrhoeae is usually isolated on Thayer–Martin agar (or VPN) agar in an atmosphere enriched with 3-7% carbon dioxide. Thayer–Martin agar is a chocolate agar plate (heated blood agar) containing nutrients and antimicrobials (vancomycin, colistin, nystatin, and trimethoprim). This agar preparation facilitates the growth of Neisseria species while inhibiting the growth of contaminating bacteria and fungi. Martin Lewis and New York City agar are other types of selective chocolate agar commonly used for Neisseria growth. N. gonorrhoeae is oxidase positive (possessing cytochrome c oxidase) and catalase positive (able to convert hydrogen peroxide to oxygen). When incubated with the carbohydrates lactose, maltose, sucrose, and glucose, N. gonorrhoeae will oxidize only the glucose. Surface molecules
On its surface, N. gonorrhoeae bears hair-like pili, surface proteins with various functions, and sugars called lipooligosaccharides.
Paternal rights
The paternity rights of a father with regard to his children differ widely from country to country often reflecting the level of involvement and roles expected by that society. Paternity leaveParental leave is when a father takes time off to support his newly born or adopted baby. Paid paternity leave first began in Sweden in 1976, and is paid in more than half of European Union countries. In the case of male same-sex couples the law often makes no provision for either one or both fathers to take paternity leave. Child custodyFathers rights movements such as Fathers 4 Justice argue that family courts are biased against fathers. Child supportChild support is an ongoing periodic payment made by one parent to the other; it is normally paid by the parent who does not have custody. Paternity fraudAn estimated 2% of British fathers experiences paternity fraud during a non-paternity event, bringing up a child they wrongly believe to be their biological offspring. Role of the father
In almost all cultures fathers are regarded as secondary caregivers. This perception is slowly changing with more and more fathers becoming primary caregivers, while mothers go to work, or in single parenting situations and male same-sex parenting couples. Fatherhood in the Western World
In the West, the image of the married father as the primary wage-earner is changing. The social context of fatherhood plays an important part in the well-being of men and their children. In the United States 16% of single parents were men as of 2013.
