Florida Panther 55
-The carcass of this approximately 11.5-year-old
radio-collared female was
recovered 12 July 2004, following detection of a mortality signal during a
routine monitoring flight. The
remains, which had been reduced to bones and hide by scavengers, were found in
the Big Cypress
National Preserve (BCNP) between US41 and I-75. Necropsy was performed at the
Wildlife Research
Laboratory (WRL) in Gainesville, and cause of death was suspected to be due to
intraspecific aggression
(ISA) based on compressive fractures of the nasal bones. No congenital defects
were observed although
severe autolysis and scavenging precluded complete examination (a slight kink
in the last vertebrae of the
tail was noted at previous captures). Rabies IFA and FeLV ELISA antigen test
were not possible due to
severe autolysis.
Florida Panther 59 - The carcass of this approximately 9.5-year-old
radio-collared male was
recovered on 22 November 2004, from private land just west of the Florida
Panther National Wildlife
Refuge (FPNWR) in Collier county. Numerous punctures were observed on the face
and cranium. Field
sign included panther scrapes on the trail to FP59’s location. FP131 was known
to be nearby and was
possibly the aggressor. Necropsy was performed at the WRL, and cause of death
was confirmed to be
ISA. Congenital defects observed included a slightly kinked tail, a cowlick,
and a cleft in the spleen.
Brain tissue tested unsatisfactory for rabies by IFA and thoracic blood was
negative for feline leukemia
virus (FeLV).
Florida Panther 117 - The carcass of this approximately 2.5-year-old
radio-collared male was
recovered from private lands to the east of Okaloacoochee Slough State Forest
(OKS) about one mile
from a major road on 28 July 2004, following detection of a mortality signal
during a routine flight.
There were no signs of thrashing or obvious signs of trauma, although blood
tinged fluid drained from the
mouth and nose when turned over for examination. Blood collected post-mortem
tested negative for
FeLV.
Necropsy was performed at the University of Florida, College of
Veterinary Medicine (UFCVM),
and an immediate cause of death was not determined. Upon microscopic
examination of tissues,
mild perivascular lymphocytic inflammation (encephalomyelitis) was seen in the
cerebrum, brainstem,
and spinal cord suggesting viral infection. However, viral culture, PCR
(canine distemper virus,
pseudorabies virus, Flaviviruses, Alphaviruses, encephalomyocarditis virus,
Neospora caninum,
Toxoplasma gondii, and Sarcocystis neurona), IHC (canine distemper virus), and
rabies IFA of brain
tissue were negative. PCR and IHC of brain tissue were also negative for FeLV.
Toxicological tests
performed at Michigan State University included gas chromatography (liver),
heavy metal concentrations
(kidney), anticoagulant screen (liver), and chlorinated pesticide
concentrations (fat); all tests were
negative or showed insignificant toxin levels. Congenital defects observed
were limited to a small cleft in
the spleen. The cause of death for FP117 remains open but was likely viral;
the case is still under
investigation.
Florida Panther 120 - FP120 was a 4-year-old radio-collared female (died at
5-years-of-age)
that was injured in a collision with a vehicle on 11 July 2004, on US41 at the
Turner River near Ochopee
in the BCNP. The panther was transported to UF–CVM for treatment and then to
White Oak
Conservation Center for rehabilitation. Ten months following the accident,
FP120 was released 6-7 miles
north of US 41 and 4-5 miles east of SR 29 in
Big Cypress National Preserve; BCNP biologists reported
that she began moving south immediately after her release and was located
within a half of mile north of
US 41 on 6 May 2005. FP120 was struck and killed by a vehicle on US 41 near
Turner River Road,
Collier County, 7 May 2005, three days after her release.
Vehicular collision was confirmed as the cause of death at necropsy. The
stomach was empty
except for unidentified small mammal hair and bones. Mild pleural adhesions
were noted in the left
thorax – possibly the result of the initial accident. Congenital defects were
limited to a small cleft in the
spleen. Rabies IFA and FeLV ELISA antigen tests were negative.
Florida Panther 126 - FP126 was a 1.5 year-old male panther that had been
relocated to OKS
due to its presence near the Green Corn Dance Ceremonial site. FP126
established a home range in and
around OKS during the subsequent 7 months but was found dead 3 January 2005 on
private land ½ mile
south of CR846 and 1.5 miles west of County Line Road following detection of a
mortality signal. Field
sign suggested ISA, and FP65 was located within ½ mile the same day.
Intraspecific aggression as the
cause of death was confirmed at necropsy.
Congenital defects were limited to a
small cleft in the spleen.
Rabies IFA was not performed due to severe autolysis; FeLV SNAP test of
thoracic blood was negative.
Florida Panther 132 - FP132 was a 3 year-old radio-collared male that died 22
July 2004, due
to septicemia likely secondary to FeLV infection. The panther’s movements had
become restricted
approximately 5 days prior to death. Necropsy revealed a large abscess over
the right quadriceps muscle,
interstitial pneumonia, and septicemia. Aerobic cultures were taken of the
abscess and lungs resulting in
heavy growth of â-hemolytic Streptococcus sp. FeLV SNAP test of serum and
aqueous humor, and IFA
of blood smears were positive. Immunohistochemistry of spleen and lymph node
were positive for p27
antigen. ELISA antigen of serum at Antech Diagnostics was negative, but this
is believed to be an
erroneous result. Virus was cultured at OSU. FP132 was positive for FeLV by
ELISA antigen (venous
serum), IFA (blood smear), IHC, PCR, and viral culture. FP132 may have been
infected by FP123
following ISA in March 2004. Congenital defects were limited to a cleft in the
spleen.
Florida Panther 136 - FP136 was a 4 year-old radio-collared female that was
found dead due to
unknown causes 14 June 2005, in the Turner River Unit of BCNP. The panther had
originally been
captured and radio-collared by the NPS on 13 January 2005. At capture, NPS
personnel noted chronic
healed injuries to the left shoulder and back (scapula and adjacent spinous
processes).
FP136 had
restricted movements since 25 May 2005, and had been in the same location for
approximately 2 weeks
before death. FP136 was emaciated but there were no obvious signs of trauma.
The panther was collected
by NPS within 2 hr of death and was delivered to the Wildlife Research
Laboratory (Florida Fish and
Wildlife Conservation Commission, Gainesville).
FP136 was subsequently
transported to the UF-CVM
for necropsy the next day (15 June).
Whole body radiographs taken prior to necropsy revealed bullet fragments
beneath the skin and in
the musculature on the right side of the chest. Healed fractures were observed
in the left scapula and
spinous processes of the adjacent cervical vertebrae. A more recent fracture
and dislocation of the spinal
column was also observed lower in the back (2nd and 3rd lumbar vertebrae).
Rounding of the fracture
edges indicated the lumbar vertebral fractures to be approximately 2-3 weeks
old.
At necropsy, gross findings included emaciation, abrasions and ulcers on the
hindlimbs, healed
fractures of the left scapula and adjacent spinous processes, and acute
fracture/luxation of the lumbar
vertebrae. Copper-plated bullet fragments were recovered from the muscle and
subcutaneous tissues of
the thorax, primarily on the right side. No evidence of trauma (skin
perforation, hemorrhage,
muscle/tissue damage) associated with the bullet fragments was observed.
Microscopically, chronic inflammation was observed in tissues around the
bullet fragments.
Interestingly, evidence of degeneration (demyelination and vacuolation) was
observed in the white matter
of the mesocephalon of the brain. The causes of these and changes and their
relationship to the panther’s
condition are unknown but similar changes have been seen in at least one
captive panther. Further
examination of these tissues is being performed by veterinary pathologists at
the University of California
(Davis).
Bullet fragments recovered at necropsy were sent to the National Fish and
Wildlife Forensics
Laboratory (Ashland, Oregon) for analysis. The fragments were examined
macroscopically,
microscopically, and by x-ray fluorescence spectrometry; however, rifling was
not present and caliber
could not be determined.
FP136 survived a shooting at some time prior to her initial capture. The
bullet likely entered the
left side and fragmented after hitting the dorsal aspect of the left scapula
and cervical spinous processes.
These fragments continued into the subcutaneous tissues and muscle of the
right side. The fragments
apparently did not penetrate the thorax and are not believed to have resulted
in serious injury. The lumbar
vertebrae fracture likely occurred 3 weeks before death. The cause of this
fracture is unknown.
Congenital defects observed were limited to small cleft in the spleen. Rabies
IFA and FeLV
ELISA antigen tests were negative.
Florida Panther Kitten 94 - The carcass of this 3.25-year-old uncollared male
was recovered
from the median on I-75 near mile marker 98 beyond the panther fence wildlife
crossing area on 17
August 2004. A transponder chip was found identifying it as K94, a kitten of
FP88 that was last handled
by NPS at 3 weeks of age in May 2001. Necropsy was performed at WRL, and
vehicular collision was
confirmed as the cause of death. Congenital defects observed were limited to a
double cleft in the spleen.
Rabies IFA and a FeLV snap test were both negative.
Florida Panther Kitten 128 - The carcass of this 2.5-year-old uncollared male
was recovered
on 7 December 2004, from CR832 about 1 mile east of the old railroad grade. A
transponder chip
identified the carcass to be K128, a kitten of FP75 that was last handled when
10 days old in June 2000.
Necropsy at the WRL confirmed vehicular collision as the cause of death.
Congenital defects included a
kinked tail, a cowlick, and a cleft in the spleen. Rabies IFA and a FeLV snap
test were negative.
Florida Panther Kitten 156 - Big Cypress National Preserve biologists
recovered the carcass of
K156 from US41 east of Ochopee in Collier County on 2 August 2004. The female
kitten was
approximately 6 months of age and weighed 20 lbs. K156 was one of two kittens
whose mother, FP120,
was captured on 11 July 2004 for treatment following collision with a vehicle.
Attempts to find her two
kittens were unsuccessful following her capture. Necropsy was performed at WRL,
and vehicular
collision was confirmed as the cause of death. The kitten was severely
emaciated and would not likely
have survived had it not been hit by car. Congenital defects observed were
limited to a small cleft in the
spleen. A FeLV snap test of thoracic blood was negative; rabies IFA was not
performed due to severe
skull/brain trauma.
Uncollared Florida Panther 67 - UCFP67 was a dependent 1-week-old female
kitten of FP113
found dead 2 September 2004 in the FPNWR. No sign of a den or other kittens
was seen. Necropsy was
performed at WRL and abnormalities observed included dehydration, emaciation,
enlarged kidneys,
enlarged submandibular lymph nodes, and numerous small lacerations over the
caudal portion of the
body. There was no milk in the stomach. Cause of death was likely septicemia,
dehydration, and
malnutrition. No congenital defects were observed. A FeLV snap test of
thoracic blood was negative.
Uncollared Florida Panther 68 - This uncollared 3 to 6-year-old female Florida
panther was
found approximately 1 mile north of BCNP Oasis Visitor Center in a small pine
island surrounded by
swamp buggy trails on 30 September 2004.
It was estimated to have been dead up
to 2 days. Based on
matted vegetation, it is thought that the panther was alive and at the site
for several days. There was no
sign of thrashing or struggle, no sign of other panthers, and no sign of
humans other than the exotic plant
removal crew who found the carcass. A necropsy was performed at WRL and cause
of death could not be
determined; however, severe autolysis and scavenging precluded complete
examination. No congenital
defects were observed (spleen not available for examination). Whole body
radiographs were negative for
bullet fragments. An FeLV snap test of thoracic blood was negative.
Uncollared Florida Panther 69 - This uncollared approximately 2-year-old female
was found
dead 25 October 2004, on SR29 approximately 2.5 miles north of CR858. Necropsy
was performed at
WRL, and vehicular collision was confirmed as the cause of death. Numerous
tapeworms were found in
the small intestine. Congenital defects observed included a kink in the tail,
a cowlick, and a cleft in the
spleen. A FeLV snap test of thoracic blood was negative. Brain was
unsatisfactory for Rabies IFA.
Uncollared Florida Panther 70 - This uncollared approximately 1-year-old
female was killed 1
December 2004, on SR29 at the curve by owl hammock radio tower about 5.5 miles
south of Immokalee.
Necropsy was performed at WRL, and vehicular collision was confirmed as the
cause of death.
Congenital defects observed were limited to a cleft in the spleen. Rabies IFA
and FeLV SNAP test of
venous blood were negative.
Uncollared Florida Panther 71 - This uncollared 2 to 3-year-old male was killed
on US41 just
east of 11-mile Road 11 February 2005. Necropsy was performed at WRL, and
vehicular collision was
confirmed as the cause of death. Congenital defects observed were limited to a
cleft in the spleen. Rabies
IFA and FeLV SNAP test of venous blood were negative.
Uncollared Florida Panther 72 - This uncollared approximately 2-year-old male
panther was
hit and killed 25 February 2005, on SR29 in Jerome. The moderately scavenged
carcass was transported
to WRL for necropsy, and vehicular collision was confirmed as the cause of
death. Congenital defects
observed were limited to a cowlick and a cleft in the spleen. A FeLV snap test
was negative. Rabies IFA
was not performed due to severe autolysis.
