Rapid PMed and real time antibiotic resistance Flashcards
what are the public health impacts of gonorrhoea?
Genital Discharge Syndrome
Reproductive and Child Health Pelvic Inflammatory Disease Ectopic Pregnancy, Infertility Congenital disease
Adult gonococcal conjunctivitis
Keratitis and rapid corneal scarring
Disseminated gonococcal infection
Risks of HIV transmission
multidrug resistance and extensive drug resistance in neiserria gonorrhoea

name the first XDR gonorrhoea strain
h041, emerged 2014, heterosexual man/japanese partner
what happens in h041 strain?
sequence variation in two hypervariable loci, porB and tbpB.
technological innovations to address antimicrobial resistance?
Molecular and Rapid Diagnostics and AMR prediction
Whole genome sequencing
Rapid Sequencing
Real Time Surveillance
how can rapid AMR detection reduce AMR transmission?
Determine Drug Susceptibility at Diagnosis
Treat patient empirically with ABx that work
Reduce Transmission of drug resistant confidently
Re-use old discarded Abx
reduced selection pressure on 1st line Abx
what is the POC test for AMR of gonorrhoea
The io ® cartridge can multiplex using a combination of 4 detection chambers and up to 6 electrochemical labels to detect up to 24 analytes from a single patient sample in 30 minutes
genital discharge and antibiotic resistance
1) treating genital discharge syndrome Chlamydia trachomatis Neiserria gonorrhoeae Trichomonas vaginalis Mycoplasma genitalium
treat with: Doxycycline
Ceftriaxone & Azithromycin
Metronidazole
Azithromycin or Moxifloxacin or Pristinamycin
what is rapid NAAT?
nucleic acid amplification test (NAAT) is a molecular technique used to detect a particular pathogen (virus or bacterium) in a specimen of blood or other tissue or body fluid. It does so by detecting and amplifying the RNA or DNA of the pathogen, that is, making extra copies of its nucleic acids
