Cappilaria aerophila infection may be of pathological
significance in Ursus americanus - American black
bears in Florida, USA. (B419.14.w14)
Occurrence
- Crenosoma sp. lungworms were found in the larger air passages of 3/53 adult Ursus americanus - American black
bears from New York (Adirondacks, plus five from Allegany State Park),
1956-1958. (J413.7.w1)
- Lungworms were found in the bronchi of the left apical lung in 3/10 adult
Ursus americanus - American black
bears trapped in the Adirondacks, and lungworm larvae were recovered from the faeces of one bear.
(J413.7.w1)
- Capillaria aerophila was found in the lungs of 10% of bears during a survey of Ursus americanus - American black
bears from six states in the southeastern USA, July 1973-November 1976. This is the first record of this parasite in
Ursus americanus. (J1.14.w10)
- Crenosoma sp. was found in the small bronchioles of 8% of bears during a survey of black bears from six states in the southeastern USA, July 1973-November 1976. It was found only in bears from mountainous areas.
(J1.14.w10)
- Capillaria aerophila was detected in the lungs and trachea of 73.2% of 46 Ursus americanus - American black
bears examined during a survey in Florida, October 1976-April 1981.
(J381.50.w1)
- Crenosoma vulpis were detected in the lungs of 2.4% of 46 Ursus americanus - American black
bears (i.e. one bear) examined during a survey in Florida, October 1976-April 1981.
(J381.50.w1)
- Crenosoma sp. was detected in the lungs of 2.4% of 46 Ursus americanus - American black
bears (i.e. one bear) examined during a survey in Florida, October 1976-April 1981.
(J381.50.w1)
- Crenosoma sp. lungworms were found in bears (in three of
53 wild Ursus americanus - American black
bears from New York). (J345.3.w2)
- These were found in the larger air passages. (J345.3.w2)
- An unidentified nematode, 300 mm long (average) and 1.5 mm wide was
found in the bronchi of a wild Ursus thibetanus - Asiatic black bear
in the south-eastern USSR. (J345.3.w2)
- Capillaria aerophila were found in the lungs of one bear (out
of 17 in which the lungs were examined) during a survey of 22 Florida black bears
Ursus americanus floridanus (Ursus americanus - American black bear)
cubs (up to 12 months old) between 1998 and 2003, with four nematodes
found. (J11.90.w2)
- Crenosoma petrowi were found in eight of 64 bears examined
during a survey of Ursus
americanus - American black bears in central Ontario, Canada,
1975-1977. In two bears there was a mixed infection with Crenosoma
potos. There was no associated gross pathology. (J30.56.w4)
- Crenosoma potos were found in three of 64 bears examined
during a survey of Ursus
americanus - American black bears in central Ontario, Canada,
1975-1977. In two bears there was a mixed infection with Crenosoma
petrowi. There was no associated gross pathology. (J30.56.w4)
- Immature Crenosoma vulpis (41 worms) were found in a cub
which died due to an adverse reaction to the anaesthetic drug when
removed from its den bears during a survey of Ursus
americanus - American black bears in central Ontario, Canada,
1975-1977. There was no associated gross pathology. (J30.56.w4)
