MITES
Mites are the most common and most dangerous of the external parasites of captive
snakes. These mites feed on the blood of their hosts, causing anemia (often severe with heavy infestations). Blood-feeding
can also transmit viruses, at least one very serious disease-causing bacterium, and blood parasites.
The snake mite completes its life cycle on its host The females, however, lay up
to 80 eggs off the snake within the immediate environment This is one reason why particulate floor coverings (corn-cob
material, pebbles, etc.) are not recommended. These substrates provide too many hiding places for the mites and
their eggs.
Snakes that are most likely to be seriously compromised by this external parasite
are those that have been recently imported and those housed under crowded, unhygienic conditions. Heavily parasitized
snakes are also likely to be adversely affected when they are suffering from malnutrition and/or other diseases
at the same time.
Veterinarians must be consulted when these various circumstances arise. These snakes
must be carefully examined and thoroughly evaluated so that underlying disease and problems with husbandry can
be identified and corrected. Furthermore, the recommended treatment can often be injurious, especially to snakes
suffering from debility and/or disease. The veterinarian must perform a thorough physical examination and may recommend
a blood analysis to fully evaluate the patient, the advisability of treatment, and the least harmful method of
treatment for mites
Several treatments are available for snake mites. One popular method involves suspending
a No-Pest Strip (Shell) above or adjacent to the snake's enclosure for 2-5 days. One expert recommends a "dosage"
of 0.2 inches of commercial strip per 10 cubic feet of enclosure. An alternative is to Place a 1-inch section of
a No-Pest Strip within a 35-mm film container with multiple perforations and suspend it inside the enclosure for
2-5 days. These products should be used cautiously, however. They can be especially toxic to severely ill and debilitated
snakes.
Flea sprays formulated for use on dogs and cats can be applied to a small towel
and the chemical can be wiped onto the skin and scales This procedure should be repeated about 10 days later. During
treatment, any particulate floor covering (gravel, crushed corncob, wood shavings, etc.) within the enclosure must
be replaced by paper or towels. All water containers should also be removed. The enclosure itself should be thoroughly
cleaned and fumigated with 10-15% solution of formalin and hot water. After a thorough rinsing, the enclosure should
be allowed to completely dry before it is re-inhabited. Treated snakes should be closely monitored for several
months for signs of re-infestation and mite-related disease.
Snake Tick infestation: Ticks resemble
oversized mites and occupy many of the same sites on the skin and scales of snakes as mites. They are often found
just inside the mouth, nostrils or vent. Even under conditions of captivity, ticks rarely reach the burdensome
numbers reached by mites. Recently imported snakes are usually the most heavily parasitized.
Like mites, ticks feed on blood of the host snake and can cause severe, life-threatening
anemia. Their blood-feeding habit enables them to transmit certain blood-borne diseases to snakes.
Manual removal of each individual tick is the most expedient treatment for tick
infestations. The hobbyist must exercise great care in performing this task Simply pulling off the tick leaves
the ticks mouth parts embedded in the skin. A small amount of alcohol applied to the exposed parts of the tick
causes it to relax and facilitates removal. The treatment methods recommended for mites are also effective. Parasitized
snakes usually require a minimum of 4 days' exposure to No-Pest Strips to kill ticks. Enlist the services of an
experienced veterinarian for a thorough pretreatment evaluation of the snake, especially if the use of a No-Pest
Strip is anticipated.
Cancer
Cancer occurs in snakes, but the number of reports is quite limited. Some of the
tumors have been diagnosed on living snakes, but most were diagnosed at the time of autopsy. As with mammals, tumors
of snakes can be benign or malignant and originate from any organ or tissue of the body, including blood.
Boa constrictors seem to be more often affected by cancer than other snakes commonly
kept in captivity. This observation, however, may be the result of the disproportionately large number of boa constrictors
kept by hobbyists because of their tremendous popularity. It is interesting to note, however, that most life-threatening
malignancies that we have diagnosed in snakes have involved boa constricts. Snake owners must be vigilant and seek
prompt veterinary help when a growth or lump is detected on their snake(s) (especially if a boa constrictor is
involved). "Mole-like" growths have been especially troublesome in our experience. Wounds that fail to
heal despite treatment should make you equally suspicious.
Organ Failure
Failure of vital organ function may be the result of advancing age or cancer but
is usually a consequence of chronic and unchecked disease among captive snakes. Disease that has gone undetected
and/or untreated can have devastating and sometimes, fatal consequences. Under theses circumstances, organ function
is greatly compromised and the snake's usually smooth-running metabolism is threatened. Dehydration and uric acid
build-up within the kidneys and possibly other vital organs further complicate the picture.
