discuss Infection caused by a specific bacteria (gonococcus) Neisseria gonorrhoeae
Gonorrhoea is a Sexually Transmitted Infection(STI)caused by the bacteria Neisseria gonorrhoeae that,if untreated may cause infertility.It can infect both men and women and typically affects one or more of the following
*urethra. *throat. *rectum. *cervix
Regular screening can help detect instances when an infection is present despite having no symptoms.Overtime ,the bacteria that causes gonorrhoea can spread to the blood stream and other parts of the body .This can lead to a serious medical condition known as Systemic gonococcal infection or Disseminated Gonococcal Infection(DGI).This infection is treatable by a medical professional .It requires a medical diagnosis.
How it spreads:
*Spreads by sexual contact.
*By having unprotected vaginal ,anal or oral sex
*People who have unprotected sex.
*People with multiple sex partners
*From mother to baby by pregnancy ,labour ,or nursing.
Symptoms:
*painful urination
*Abnormal thick discharge from the genital area
*Men may experience testicular pain and women may experience pain in the lower stomach.
*spotting between menstrual periods
*painful bowel movements
*Anal itching
In some case gonorrhoea has no symptoms .

Pick one of the following and discuss: Characteristic Virulence factor Infection caused by specific bacteria. Example: subject – Chap 18: Virulence factors of Staphylococcus aureus.
Pathophysiology: Describe the sequences of events from a Neisseria gonorrhoeae bacterial infection and any potential consequences in a male.
For the following bacteria, Neisseria gonorrhoeae, please answer the following: Name of disease and associated pathogen stated in both scientific and common form. Method(s) of transmission described. Short and long-term effects on the body described in detail. Detailed explanation of incidence of disease (who, where, when) including relevant, current statistics from credible sources
Neisseria has acquired resistance to penicillin. How can it achieve this? A) Neisseria bacteria are dormant and penicillin works on active cells B) Neisseria bacteria are too small for penicillin to kill C) Neisseria bacteria are constantly changing for penicillin to work D) Neisseria bacteria produces proteins to make penicillin ineffective
QUESTION 14 Through the microscope, these bacteria appear as Gram-negative diplococci typically flattened where the cocci meet. There are 13 serogroups that are transmitted person to person by aerosolized respiratory tract secretions. The bacteria typically infect the nasopharynx of humans causing a usually mild or subclinical upper respiratory infection, but in about 15% of these individuals the organism invades the blood and disseminates causing septicemia. From here it often crosses the blood-brain barrier causing 2000 - 3000 cases of meningitis...
A patient has a blood infection caused by a gram negative bacteria species. Why might it be dangerous to treat this infection with fast acting "cidal" antibiotic?
NEISSERIA EXPERIMENT MICROBIOLOGY LAB (Revised March 2016) Background There are two main pathogens in the genus Neisseria: N.gonorrhoeae and N meningitidis, along with many species which are normal flora for mucus membranes like the nasopharynx, vagina, urogenital tract, etc. In order to diagnose gonorrhea in a male, a Gram stain of the urethral discharge should reveal Gram negative diplococci and many white blood cells. This is considered sufficient grounds to treat for gonorrhea. In a female, diagnosis must be based...
QUESTION 22 These cell wall proteins allow many bacteria to adhere tightly to host cells, colonize, and resist flushing. This is used as a virulence factor by Bordetella pertussis, Helicobacter pylori, and Streptococcus pneumoniae, and Neisseria gonorrhoeae. This best describes what? Bacterial flagella and axial filaments. Bacterial cell surface proteins called adhesins. Bacterial capsules (glycocalyces). Bacterial invasions Bacterial pili.
Research a specific type of drug-resistant bacteria. Discuss the mechanisms by which resistance arose in this type of bacteria. If this type of bacterium was present at the same time in the same person as another mildly pathogenic bacterium, how would the resistance spread to the second type of bacteria and how would that bacteria become more pathogenic over time?
QUESTION 18 These structures are protein tubules with adhesive tips that the bacterium can change. The adhesive tips are able to adhere to receptors on host cells, enabling the bacterium to colonize and resist flushing. They are used as a virulence factor by such bacteria as Neisseria gonorrhoeae and Neisseria meningitides, and Pseudomonas aeruginosa. This best describes what? Bacterial flagella and axial filaments. Bacteria cell surface proteins called adhesins, Bacteria capsules (glycocalyces) Bacteria invasions Bacteria pili
