Occasional deaths occur in young, previously healthy individuals because of blood volume depletion (due to dehydration), and in people who are elderly or immunocompromised.Some individuals (1–2 in 100,000 cases) develop Guillain–Barré syndrome, in which the nerves that join the spinal cord and brain to the rest of the body are damaged, sometimes permanently. This occurs only with infection of C. jejuni and C. upsaliensis. Other factors
In patients with HIV, infections may be more frequent, may cause prolonged bouts of dirty brown diarrhea, and may be more commonly associated with bacteremia and antibiotic resistance. In participants of unprotected anal intercourse, campylobacteriosis is more localized to the distal end of the colon and may be termed a proctocolitis. The severity and persistence of infection in patients with AIDS and hypogammaglobulinemia indicates that both cell-mediated and humoral immunity are important in preventing and terminating infection. Cause
Campylobacteriosis is caused by Campylobacter bacteria (curved or spiral, motile, non–spore-forming, Gram-negative rods). The disease is usually caused by C. jejuni, a spiral and comma-shaped bacterium normally found in cattle, swine, and birds, where it is nonpathogenic, but the illness can also be caused by C. coli (also found in cattle, swine, and birds), C. upsaliensis (found in cats and dogs) and C. lari (present in seabirds in particular).One effect of campylobacteriosis is tissue injury in the gut. The sites of tissue injury include the jejunum, the ileum, and the colon. C jejuni appears to achieve this by invading and destroying epithelial cells.C.
Risk Factors
Infection with certain strains of Neisseria gonorrhoeae
Prolonged infection
Female sex (due to asymptomatic infection, and therefore prolonged infection)
Sexual promiscuity
Immune system deficiencies
Infection during menstruation, pregnancy, or in the puerperium period

Symptoms
Fever
Migratory arthralgias
Hemorrhagic pustules
Tenosynovitis
Rarely headache, neck stiffness, and visual changes (associated with meningitis)

Treatment
Treatment typically consists of cephalosporin and fluoroquinolone antibiotics. Gonococcemia is typically treated with intravenous or intramuscular cephalosporin antibiotics. Approximately 10-30% of gonorrheal infections present with a co-infection of chlamydia, so it is common to add a one-time dose of oral azithromycin or doxycycline for coverage of Chlamydia trachomatis. Bacterial resistance to antibiotics is increasingly common in Neisseria gonorrhoeae, so it is often advised to check susceptibility of the bacterial culture and then adjust the antibiotic therapy as needed. Pathogenesis
Neisseria gonorrhoeae is transmitted during sexual contact with an infected individual. The bacteria invade the non-ciliated columnar epithelium of the urogenital tract, oral mucosa, or anal mucosa following exposure. Invasion of the host cells is made possible due to virulence factors such as Pili, LOS, Opa, and others. Similarly, these virulence factors can be used for avoiding the host immune system, which may explain prolonged infection, bacterial resistance, and gonococcemia. See also
