Monitoring changing toxigenicity
of a cyanobacterial bloom by molecular methods.
According to cultural characters, biochemical tests and Elek's toxigenicity
test, these were C.
At CDC's Diphtheria Laboratory, this isolate demonstrated weak toxigenicity
coli are classified into distinct groups on the bases of toxigenicity
diphtheriae isolates were sent to National Institute of Public Health-National Institute of Hygiene for confirmation and toxigenicity
testing, biotyping, pulsed-field gel electrophoresis (PFGE), multilocus sequence typing (MLST), and ribotyping.
Atehnkeng J, Ojiambo PS, Donner M, Ikotun T, Sikora RA, Cotty PJ and R Bandyopadhyay Distribution and Toxigenicity
of Aspergillus species isolated from maize kernels from three agro-ecological zones in Nigeria.
Information on biochemical identification, toxigenicity
and antimicrobial susceptibility to this bacterium is scanty.
For most cases, toxigenicity
was confirmed by using the Elek phenotypic test (9).
FRC24 is a toxigenic isolate; toxigenicity
was confirmed by both tox gene detection and Elek test (1).
was verified by real-time PCR (8) and a modified Elek test (6).
The presence of ctxA and ctxB genes confirmed the toxigenicity
of all isolates, and tcpA PCR product size and sequence identified El Tor biotype strains.
of the strain, named KL126, was verified by using a C.
