Definition/Description[edit | edit source]
Tularemia, named after the infectious gram-negative bacterium Francisella tularensis, is a zoonotic disease. A zoonotic disease is one that is spread from animal to human (infected humans can NOT pass the disease to other humans). This spread may be directly i.e. handling contaminated meat or through a carrier i.e. a tick. It is also known as “Ohara’s disease”, “rabbit fever”, “deer-fly fever”,[1] “market’s men disease”, “meat-cutter’s disease”, “glandular type of tick fever”, “water rat-trappers’ disease”. It is highly infectious, <10 organisms causing severe disease in both humans and animals.[2] There are 4 sub-types of the bacterium, the most common in the United States are Type A, tularenis, and Type B, holarctica. It is on the Center for Disease Control’s list of bioterroism threats.
Prevalence[edit | edit source]
The prevalence of Tularemia in the United States depends on the geographical location and the time of year. During the spring and summer months (May-September), there is a rise in reported cases. South-Central, Pacific Northwest, and parts of the East Coast have the highest incidence of Tularemia. While the population most effected is young males 5-9 years old and those > 75 years old.[3]
The above images from: http://www.cdc.gov/tularemia/statistics/.
Characteristics/Clinical Presentation[4][5][6][3][1][edit | edit source]

|
|
Note: The 2 most common forms are glandular/ulcerglandular and pneumonic.
Those occurring in ≥25% of those infected with the glandular and ulceroglandular form are in bold[4]
Those occurring in ≥25% of those infected with the pneumonic form are in italics[4]
Expectations/Prognosis[5][edit | edit source]
Untreated: Fatality ~5%
Treated: Fatality <1%
Poor outcomes have been associated with those who have underlying co-morbidities such as alcoholism or diabetes and those who delay seeking medical treatment.[4]
Medications[4][edit | edit source]
Antibiotic therapy is used to treat Tularemia. Streptomyocin and Gentamicin are usually the first administered. Ciprofloxacin along with other fluoroquinolones. Tetracycline and chloramphenicol may also be used to treat Tularemia, however they have higher relapse rates than the previously mentioned.
Resistant to beta-lactam antibiotics and azithromycin.
Diagnostic Tests/Lab Tests/Lab Values[4][5][edit | edit source]
There are numerous ways to test for F. tularensis:
• Gold Standard: Bacteriologic Culture[2]
• Most Common: Serology[2]
• Polymerase Chain Reaction of sample ulcer
• Direct Stains
• Blood Culture
• Direct Fluorescent Antibody Stain
• Slide Agglutination
• Antimicrobial Susceptibility
• Biochemical Identification
• Enviornmental Specimen Evaluation
• Chest X-ray
Etiology/Causes [2][edit | edit source]
Direct transmission occurs from direct contact with the infected animal or direct contact from soil, water, or landscape. This may be from ingestion of contaminated meat (most likely rabbit), water, or inhaled dust. It can also be passed from handling or skinning contaminated animals or from a bite/scrath from a contaminated animal. Animal hosts that may spread Tularemia include lagomorphs (rabbit and hare), rodents, insectivores, carnivores, ungulates, marsupials, birds, amphibians, fish, and invertebrates. Secondary carriers include ticks, mosquitoes, biting flies or deerfly. With such a wide variety of hosts and carriers available of this disease, it is has the possibility to appear/outbreak in other regions.
Systemic Involvement [4],[5][edit | edit source]
- Supporation of local lymph nodes
- 2o Pneumonia
- Hematogenous Spread to other organs resulting in:
Pericarditis
Osteomyelitis
Meningitis
Sepsis
Hepatitis/Jaundice
Splenic Rupture
Encephalitis
Peritonitis
- Renal Failure
- Rhabomyolisis (typhoidal form)
- ARDS (penumonic form)
- Lung Abscess (pneumonic form)
- Fibrosis/Calcification of affected lung areas (pneumonic form)
- Pleuritis (pneumonic form)
With all forms of Tularmemia illness MAY result in such debilitating conditions (more so when other systems are involved), that recovery can take several months.
Medical Management (current best evidence) [edit | edit source]
Antimicrobials are currently the best treatment option for Tularemia infections. After beginning treatment one should expect to see an improvement in symptoms and fever within 24-48 hours.[4]
- Aminoglycosides[1]
- Streptomyocin 10-14 days (1st choice)
- May also be treated with gentamicin or tetracycline for 14+ days
Tetracycline should not be used as a treatment in those whose permanent teeth have not came in.[5]
- Quinolones
- Contraindicated in those < 18 years of age
- "well tolerated, achieve adequate blood levels...and have excellent intracellular penetration"[6]
A review of 10 documented treatment cases in the United States found that those treated with Aminoglycosides have a 6-12% relapse rate of infection, while those treated with Quinolones had a 0% relapse rate.[6]
Physical Therapy Management (current best evidence)[edit | edit source]
Currently did not come across any management in regards to physical therapy.
Points to consider:
- Pt's with tularemia present with generalized musculoskeletal aches.
- Pt's who have complications develop 2o to their primary Tularemia infection may take months to recover. During this time physical therapy may play a roll in conditioning,balance retraining, rebuilding strength and endurance, and regaining patient's independence in their functional roles in society and home.
Differential Diagnosis[edit | edit source]
Alternative Diagnosis
Differential Characteristics to rule out Tularemia
Glandular[4][edit | edit source]
- Bubonic Plague

- Cat-Scratch Disease
History of cat scratch
Takes weeks to develop
- Myobacterial Infection
Lymph Nodes painless/non-tender
- Sporotrichosis
No systemic symptom
Lymph nodes painless
History of contact w/ soil/plants
Lesions along lymphatic chains
