No full textIn this study, a case of candidemia caused by Candida hellenica as the
first report in our country was presented. Fluconazole and liposomal
amphotericin B treatment was initiated in a 20-year-old male patient in
October 2018 due to the diagnosis of candidemia following esophageal
surgery. The patient had a history of multiple esophageal operations.
The patient was discharged during the last 24 hours due to the lack of
fever, improvement in general condition and lack of growth in blood
cultures. Germination tube test of the Candida isolate grown in blood
culture was negative and the colony morphology in corn meal tween 80
agar was not defining. It was identified as C.hellenica according to the
profile obtained from the ID32C (R) (bioMerieux, France) method based on
carbohydrate assimilation. The target ITS regions of the rRNA genes were
amplified by polymerase chain reaction and sequenced using suitable
primers for the confirmation of the identification on species level. The
DNA sequences obtained were searched by using the ``National Center for
Biotechnology Information (BLAST){''}
(http://www.ncbi.nlm.nih.gov/BLAST/) database and the isolate was
identified as C.hellenica with a 99\% homology with GenBank sequences.
MALDI-TOF (Vitek MS, bioMerieux) could not identify the yeast isolate.
The reference microdilution method was performed according to the
recommendations of the Clinical and Laboratory Standards Institute in
order to test the antifungal susceptibility. The minimal inhibitory
concentrations for the isolate, determined after 24-hour incubation were
0.25 mu g/ml for amphotericin B, 8 mu g/ml for fluconazole, 0.25 mu g/ml
for voriconazole, and 0.25 mu g/ml for itraconazole. As our case had a
previous history of gastrointestinal tract surgery it was thought that
gastrointestinal tract was the endogenous source of candidemia by
leading to mucosal disruption and this mucosal disruption might
facilitate the translocation of Candida. The carbohydrate assimilation
test ID32C (R), was able identify the causative agent of candidaemia at
the species level in this case. However, uncommon or previously
unrecognized organisms may be misidentified by commercial systems. While
the phenotypic definition is sufficient in routine laboratories, it is
mandatory to confirm the microorganism species definition by DNA
sequence analysis, as done in this case. We have presented a correctly
identifed and successfully treated candidemia case. Although the
candidemia was not mortal in our patient, the mortality rate of
candidemia which is 50\%, should be remembered. A total of two
C.hellenica infections have been reported in the literature, including
one candidaemia and one respiratory tract colonization. Our successfully
treated case was presented to draw attention to this rare infectious
agent

No full textDetermination of Electron Swarm Parameters and Limiting Electrical Field during Martian Dust Storm Season Using Boltzmann Analysis
No full textIn the ternary mixture of 95.7\% CO2 + 2.69\% N-2 + 1.59\% Ar with
various dust loads representing the Martian atmosphere, ionization,
attachment, electron mean energies and electron drift velocities are
numerically calculated by a two-term Boltzmann equation analysis at L-s
= 270 degrees. The attachment coefficient defined carries dissociative
attachment collisions of the CO2 component in the ternary mixture
together with electron attachment to uncharged dust grains in the dusty
storm season. The limiting E/N values for the critical condition where
ionization rates are balanced by attachment collisions in the low
pressure plasma (E is the electric field produced by the dust storm and
N is the total number density of gas molecules in the ternary mixture)
are evaluated for various dust loads. The limiting E/N increases as a
function of dust grain size and the effect is more pronounced for dust
loads with higher grain densities
