Bacterial STI’S Flashcards
(22 cards)
What type of bacteria is chlamydia infection?
Gram-negative(sort of)
What are the features of a chlamydia bacterial cell?
No cell wall
Chlamydia bacterium comes in two forms what are these?
Elementary bodies (EB) and reticulate bodies (RB)
What’s the difference between elementary bodies and reticulous bodies in chlamydia infection
Reticular bodies cause disease an elementary bodies cause infection of other people
What type of cells are chlamydia cells
Intracellular pathogens
Describe some features of chlamydia bacteria
- Do you not have genes required for ATP production.
- Require a host cell to produce ATP
- Require two forms for development
What are the three species of chlamydia
Chlamydia trachomatis this is the one that causes STIs , chlamydia pneumonia which is one that causes pneumonia and chlamydia Psittaci ( from birds ) flu like symptoms/pneumonia
How is Chlamydia transmitted?
- Unprotected vagina, oral or anal sex
- Unwashed sex toys
- Genital genital contact (no penetration, orgasm or ejaculation)
– Semen or vagina fluid in eye 
What is contract tracing in STI
Whereby the person who has tested positive for an STI has to inform the previous sexual partners and then they have to inform the sexual partners and so on… 
What are the symptoms of chlamydia in women?
- Often asymptomatic (85%) – Unusual vagina discharge – Pain when urinating – Pain during sex or bleeding after sex – Secondary infection can lead to pelvic inflammatory disease
Symptoms of chlamydia in men?
– Most men have symptoms (75%)
– white/cloudy watery discharge
– Pain or burning when urinating
– Testicular pain or swelling
Why are penicillins and cephalosporins not suitable in treating chlamydia infection?
These agents can only stop further growth of the bacteria but cannot kill them, meaning that after the antibiotic is stopped, the infection tends to return.
Name the four types of bacterial STI is common in the UK
– Chlamydia
– Gonorrhoea
– Syphilis
– Non-specific urethra -itis
What type of bacteria is gonorrhoea?
Gram-negative
What is a true pathogen? 
A true pathogen is whereby if somebody has that in their body and it is causing an infection. 
A confirmed diagnosis of gonorrhoea can be a sign or indication of child/ sexual abuse ? True or false
True
Chlamydia infection found in the child can indicate child/sexual abuse question. True or false?
False, children can carry the disease and this does not necessarily mean abuse. 
Symptoms of gonorrhoea in a man
- Insufferably symptomatic – Acute inflammation – Painful urination – Oozing discharge (drippy Willy) – Can invade prostate and epididymitis (that is the tube at the back of the testes) and can cause infertility
What are symptoms of gonorrhoea in the female?
- Often asymptomatic
– Often mistaken for bladder infection
– Infects cervix
– Can lead to PID (pelvic inflammatory disease) which can lead to infertility
Can penicillins and cephalosporins  be used to treat chlamydia?
No due to the inability to kill the disease, they only stop growth and therefore the disease is likely to return. 
What is the treatment for chlamydia?
Either a single dose azithromycin or 7 days treatment of doxycycline or 14 days of erythromycins
What is the treatment for gonorrhoea?
Single intramuscular antibiotic injection of ceftriaxone 
Followed by a single antibiotic dose of Azithromycin
It is sometimes possible to have another antibiotic tablet instead of an injection (cifixime or ciprofloxacin)
