Genus Tatumella
Tatumella ptyseos is the only species of the genus
Tatumella
...
In addition, Tatumella isolates are slow growing,
produce tiny colonies, and are relatively nonreactive in
laboratory media
...

Scientific information
about
Tatumella
species is scarce, as
are confirmed human
infections
...
Ptyseos
(Tatumella
from
Harvey Tatum a CDC
microbiologist,
and
ptyseos, epithet of
sputum, given the
large
number
of
isolates from that
source)

...
Differences between T
...
DNA studies
have shown Enterobacter agglomerans to be the closest
Enterobacteriaceae species, but the homology does not
exceed 38%
...
ptyseos and both E
...
A tight phylogenetic affiliation
between Pantoea and Tatumella was recently
demonstrated by partial sequencing of elongation factor
Tu gene (tuf) and F-ATPase â sub unit gene (atpD)
...

T
...
Causes infection
usually in patients with low immunity (associated with
diabetes and tuberculosis)
...
Newborn and old
organisms are more susceptible
...
It was found sensitive to all the drugs tested
...
She reported a gastric reduction surgery two
years before; an emergency
exploratory laparotomy was performed
...
Two days
later she started to have
high fever, chills, tremor and hypotension
...
An intravenous central line
with secretions was observed;
no other obvious source of infection was identified
(Normal abdominal CT, chest X ray and urinanalysis);
consequently, a sepsis-associated catheter diagnosis was
made

antimicrobial susceptibilities (MIC): amikacin (<16),
ampicillin (>16), ampicillin/sulbactam (<8/4), ceftazidime
(<2), cefazolin (<4), cefepime (<4), cephalothin (<8),
ceftriaxone (16), ciprofloxacin (<0

She was put on a
new antibiotic scheme with ampicillin/sulbactam; after 10
days, she was discharged, completely recovered
