What is it?
Roundworms, also called nematodes, are common intestinal parasites in Barbary squirrels, particularly when they are raised in captivity or in groups.\n\nThese worms live in the animal's digestive tract and feed in part on its diet, which can cause progressive weight loss and a general decline in fitness.\n\nThe infestation often remains discreet at first, which makes regular monitoring particularly important in this species of rodent.
Commonly observed signs
These signs are neither exhaustive nor specific. Only a veterinarian can establish a diagnosis.
Related signs — each one links to its page:
The most common signs are diarrhea that is sometimes intermittent, hair that becomes dull and less silky, weight loss despite a retained appetite or, on the contrary, a decrease in appetite.\n\nThe stomach may appear swollen in young individuals. In large infestations, we can sometimes observe roundworms, resembling small whitish threads, directly in the stools.\n\nA parasitized squirrel may also appear less active, more despondent, with slowed growth in young ones.
When to consult without delay
This list does not replace veterinary advice. It gathers situations that justify a prompt consultation.
Causes and risk factors
The disease is caused by intestinal nematodes, non-segmented roundworms, several species of which can affect squirrels and related rodents. These parasites lay eggs passed in the stool, which then contaminate the environment.
Young squirrels, animals living in groups or in poorly maintained enclosures, as well as those with insufficient litter hygiene, are most at risk. Stress, an unbalanced diet or weakened immunity also increase the risk of severe infestation.
Transmission
Contamination occurs mainly orally, by ingesting worm eggs present in an environment soiled by contaminated excrement: litter, soil, food or water. Close contact between animals in the same enclosure favors the spread.
Diagnosis and care
Diagnosis is the veterinarian's responsibility, based on clinical examination and laboratory tests. Care is decided case by case.
The veterinarian confirms the diagnosis by examining the stool under a microscope, called coproscopy, which can identify worm eggs. Several samples may be necessary if the infestation is weak.
Treatment
Treatment is based on the administration of antiparasitics specific to nematodes, prescribed and adapted by the veterinarian to this particular species. Nutritional support may be associated in the event of significant weight loss.
Treatment depends on the cause and the animal's condition: it must be determined by a veterinarian. No self-medication.
Prevention
Frequent and rigorous cleaning of the enclosure, litter and accessories greatly limits the risk of contamination.\n\nIt is recommended to avoid overcrowding in the same space and to quarantine any new animal before introducing it into a group.\n\nRegular parasitic checks, on veterinary advice, make it possible to detect an infestation before the appearance of marked symptoms.
Possible complications
A massive, untreated infestation can lead to intestinal obstruction, severe dehydration and significant general weakening, especially in young animals, which can be life-threatening.
When to see a veterinarian
Presence of visible worms in the stools.\nPersistent or recurrent diarrhea.\nUnexplained weight loss.\nAbdominal bloating in a young squirrel.\nDejection or prolonged loss of appetite.
Prognosis
The prognosis is generally good when the infestation is detected and treated early. He becomes more reserved in the event of a delay in treatment, particularly in young people or already weakened animals.
Frequently asked questions
Are squirrel roundworms transmissible to humans?
The risk of transmission to humans is considered very low for nematodes specific to this species, but good hygiene after handling is still recommended.
How do I know if my squirrel has worms?
Only a stool examination carried out by a veterinarian can confirm an infestation, because the visible signs are not always present.
Should we treat all the squirrels in the same enclosure?
Yes, in general, because contamination spreads easily between animals sharing the same space and the same bedding.
Can we completely prevent the appearance of roundworms?
It cannot be completely eliminated, but rigorous hygiene and regular checks significantly reduce the risk.
