However, due to the high cost many clinical microbiology laboratories use alternative methods such as the double-disc synergy test (DDST
) and the combined disc (CD)/disc potentiation test (DPT).
In regard to developmental assessment, 741 out of the 1000 subjects (74.1%) had normal, 140 (14%) had risky, and 119 (11.9%) had abnormal findings on the DDST
The DDDT test was used to confirm that strains were positive by DDST
. Standardized inoculum conforming to 0.5 McFarland standards of suspected ESBL-producing isolates were inoculated as previously described.
In addition, they deployed a DDST
to Port Arthur, Texas, and several personnel to support sister battalion operations in San Diego and Philadelphia.
with imipenem-EDTA DDST
or alternative DDSTs
, such as those using 2-mercaptopropionic acid, which appears to be more sensitive for detecting MBLs among Acinetobacter spp.
ESBL screening using DDST
and CDDT showed that 110 (73.3%) isolates were confirmed as ESBL belonging to female patients and age groups of 16-35 (56.7%) and 36-50 (16.7%) years old.
Among the CP strains, MBL was detected in 134/138 (97.1%) isolates both by CDT and DDST
including 90 (67.16%) Klebsiella pneumoniae and 44 (32.84%) E.coli.
Comparison of DDST
and CLSI confirmatory test showed that the DDST
detected 145 (67.8%) isolates while 213 (99.5%) ESBL K.
* The 839th Battalion Headquarters and DDST
supported exercise Natural Fire 10 by conducting cargo download and upload operations in Mombasa, Kenya and coordinating onward movement to training areas in Kampala, Uganda.
Phenotypic identification for ESBL production was confirmed by double disk synergy test (DDST
) and phenotypic confirmatory double disk test (PCDDT) according to CLSI guidelines.
However, due to high cost many laboratories use alternative methods as the DDST
