Two hundred and thirty-six E. coli isolates n=236 were collected. Antibiotic susceptibility and ESBL production were studied by disc diffusion and DDST (double disk synergy tests) according to Clinical Laboratory Standards Institute guidelines (CLSI)
and EUCAST for ESBL.
75 (32%)of total isolates demonstrated MDR (multi drug resistance),62 of resistant bacteria (26% of total) were determined as ESBL producers.
In conclusion, we recommend adding this standard, cheap ESBL detection method to the routine microbial susceptibility tests run in Syrian hospitals in order to determine and isolate the sources of MDR infections and do some effort to contain and eliminate those strains.
This research aims at establishing
and testing protocols for isolation, in vitro proliferation, phenotyping, and
differentiation of MSCs embedded in umbilical cord tissues of Syrian
newborns.
MSCs were isolated from two caesarian births depending
on their
adherence characteristic on plastic surfaces, and cells were cultured in MSC
medium for their growth and proliferation. Cell phenotyping was performed by
flow cytometry using fluorescent monoclonal antibodies specific to MSCs’
surface markers. Cultured cells were passed several times and a portion of
these cells was cryopreserved in liquid nitrogen, and cell viability was assessed.
Differentiation of these MSCs into adipocytes was conducted using culture
medium Indomethacin and hydrocortisone.
