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.
PCNA is synthesized in early G1 and S-phases of cell cycle. Tight linkage to cell
proliferation has led to the investigation of its role in the evaluation of tumors for
prognosis. The aim of this study is to use computerized image analysis to measu
re
PCNA and CD31 antibodies in a series of canine melanocytic tumors to assess density
of marked cells by these antibodies, and to correlate density of marked cells with
malignant degree of these tumors through comparative study between CD31, PCNA
and microscopic aspect. 12 dog melanic tumors were diagnosed during the period
2001–2010 in Pathology Department USAMV Cluj-Napoca, for PCNA expression
study, and 10 samples of them were treated with CD31 marker by immunohistochemical
for comparative study.
