Microscopic agglutination test: Variables that affect the time of serological confirmation of human leptospirosis cases
Exequiel Scialfa, Mariana Rivero, Sergio Moreno, Marcela Ortiz, Fabricio Bongiorno
Rev Argent Microbiol. 2020;52:278-82
568
Highlights

  • 64% of cases are confirmed by MAT with the first clinical sample.

  • Human cases of leptospirosis are confirmed 21 days after the onset of clinical signs.

  • Ballum and Canicola were the most reactive serogroups.

  • The confirmation time depends on the distance of the health region from the reference laboratory.

  • The number of serogroups that cross-reacted decreased as the disease progressed.

Highlights

  • Co-occurrence of qnrS and VIM-11 in P. aeruginosa was detected.

  • qnrS1 and blaVIM-11 were located in the different plasmids.

  • qnrS1 harboring plasmid corresponded to IncR group.

  • qnrS1 plasmid was non-conjugative, however it presented an OriT region (transferable plasmid).

  • qnrS1 plasmid also carried aminoglycoside resistance genes.

Rev Argent Microbiol. 2020;52:272-7
492
Highlights

  • The use of the RHT significantly increased the frequency of HIV diagnosis.

  • Approximately one of three individuals had never tested for HIV previously.

  • No access to medical care and irregular condom use associated with no HIV testing.

  • Tendency toward a higher HIV prevalence in patients with no prior HIV testing.

  • Use of RHT slightly incremented the receipt of confirmatory results.

Highlights

  • The prevalence of syphilis is high in HIV-infected men in Istanbul, Turkey.

  • The rate of syphilis was found to be significantly higher in MSM HIV infected patients than heterosexual HIV infected patients in Turkey.

  • Findings of the study highlight the fact that patients infected with HIV must be screened for syphilis at least annually and must be informed about STDs.
