Lessons Learned
Lessons Learned
• Improvisation is an important tool for any
scientist in an austere environment
Leishmaniasis
• Endemic to any river adjacent area in
Iraq
• Samples to Walter Reed Army Institute
of Research
• Saw 0 cases contracted in Tikrit in 2010
• Tested four wounds which were
recurring rashes irritated by scratching
Malaria
• Endemic to the region
• Saw only two cases of Malaria
in one year (both imported)
Malaria
A. The BinaxNow Rapid Malaria Assay reporting 3 lines: positive control, T1 and T2, indicating an
infection with Plasmodium Falciparum alone or mixed with other Plasmodium species. B. A
trophozoite in a erythrocyte. C. A trophozoite in an acanthocyte (spiculated RBC). D. Two cells with
trophocytes and a gametocyte.
Lessons Learned
• Improvisation is an important tool for any
scientist in an austere environment
• Just because you are looking for it doesn’t
mean you will find it
Bacterial Resistance
• Itinerant population
– Soldiers who are coming and going on
missions
– Contactors whose health problems may
send them back to their home countries
– Locals who may or may not be allowed to
return for additional medical attention
• Unconventional use of antibiotics
CSH Relocation
• Moved 2 miles up the road
• OR, EMT & ICU moved from hard
stand buildings (brick and wood) into
temper (tents)
• First two cases in OR micro found
pseudomonas and acinetobacter
Dehydration
• The majority of Micro testing was from urine
samples (371)
• Urine culture was a reflexed test in the chain:
– Urinalysis (cloudy, blood, leukocytes)
– Microscopic (bacteria 1+, RBC 1+, WBC)
– Urine Culture
• Test strip specific gravity (correlated with
refractometer data) > 1.030 in 76 of urine
cultures
Lessons Learned
• Improvisation is an important tool for any
scientist in an austere environment
• Just because you are looking for it doesn’t
mean you will find it
• Microbiology is IMPORTANT
Identification Without Alcohol
• Siemens Autoscan VP requires
alcohol reconstitution of reagent
• In Lieu of reagent ran testing without
VP well and looked at results (pos &
neg) and correlated with colony
morphology and clinical
manifestation
Identification of No Bacteria
• Refrigeration temperature
easy to maintain
• Subzero not difficult
• Room temperature most
difficult
Identification of No Bacteria
• Found that growth well Pos, all
other wells Neg = acinetobacter
• Colony morphology and growth
identical to very slow growing,
susceptible enterobactericeae
species
Lessons Learned
• Improvisation is an important tool for any
scientist
• Just because you are looking for it doesn’t
mean you will find it
• Microbiology is IMPORTANT
• Overreliance on equipment can be
problematic
