A botfly's larva, called a cuterebra, can infect humans, dogs, cats, and ferrets. A parasitic larva that can develop and live beneath the skin of a mammal until it's ready to emerge and finish its life cycle seems like something from a science fiction film. Treating this extremely common problem involves removing the unwanted larva. Here are some things to be aware of regarding feline cuterebra.
What is Cuterebra?
What is Cuterebra?
The scientific term "cuterebra" refers to a particular kind of botfly that, when its larvae enter a cat's body, can cause cuterebriasis, a parasitic infection. Warbles are an alternate term for cuterebral lesions. Although they are not the best hosts for cuterebra, cats can contract the infection if they come into contact with botfly eggs. Larvae of cuterebra are often as much as an inch long, have a gray or brownish appearance, and resemble short, fat worms.
The Cats' Infection by Cuterebra
Large flies called cuterebra, also known as warble flies, lay their eggs close to the burrows and nests of small mammals such as rabbits and rats. The eggs may attach themselves to passing hosts and hatch when the host animal's body heat is sufficient. During grooming, the freshly hatched larvae usually penetrate the animal's body through the mouth, nose, or open skin wounds. Through a tiny, circular breathing orifice on the skin, the larvae travel and develop within the host's body. The larvae grow after around 30 days and fall off their host to pupate on the soil before becoming adult flies.
Cats with Cuterebra symptoms
Usually, a cuterebra shows as a swollen region beneath the skin without a little hole in the middle. Although they can appear everywhere on the cat's body, these lesions are frequently observed close to the head or neck. Unless they encroach on delicate tissues, they are usually not unpleasant. But the swelling can annoy the cat and make it groom itself more. The breathing opening of the larva may be covered in matted hair.
Cuterebra lesions typically go undetected until the larva grows to the point where it produces a lump and swelling. Sometimes the larva will reach adulthood and emerge from the cat's body before anyone ever sees it. An abscess may develop from a bacterial infection in the residual skin lesion.
Cuterebra Problems
Cuterebra larvae can move to the sensitive tissues of the head, brain, nose, eyes, and throat in rare but dangerous circumstances. If a lesion affects the brain and spinal cord, it can cause cerebrospinal cuterebriasis, which can result in neurological issues like seizures, circling, abnormal behavior, and blindness. Feline ischemic encephalopathy is a neurological disorder that may be brought on by cuterebra infections. If your cat exhibits any swelling anywhere on its body, get in touch with a veterinarian. If a larva has left the cat, treatment can still be necessary.
What Leads to Cat Cuterebra?
Cuterebra considers cats to be "accidental" hosts. Most frequently, when they are out hunting and investigating the burrows filled with tiny wild animals, they come into contact with botfly eggs. As a result, indoor cats are considerably less likely than outdoor cats to get cuterebriasis. Cuterebra is widespread throughout the Americas. In North America, the summer and autumn are when infestations happen most frequently. Although humans cannot contract Cuterebra from their cats, direct contact with botfly eggs can result in the development of a lesion.
How to Handle Cat Cuterebra
If fly larvae are present, removing them from the body is the initial step in treating cuterebra lesions. To get rid of the larvae and effectively clean the wound, your veterinarian could advise giving your cat some sort of anesthesia. Larva removal is a relatively simple process but can be challenging. It is best to remove the larva in its entirety to prevent infection. The veterinarian will use forceps to grab the larva after enlarging the breathing opening.
Following the entire removal of the larva, the residual incision is cleansed and drained. Cuts are made to unhealthy tissue to encourage recovery. Antibiotic therapy may be required for the afflicted feline. If the wound is really inflamed, a prescription for painkillers and anti-inflammatory medicines may be issued to ease the discomfort.
Prognosis of Cuterabra in Cats
As long as they are prevented from grooming the injured region while the lesion heals, cats usually recover well from cerebral lesion excision. It could be necessary for your cat to wear an e-collar, or cone, until the wound heals entirely.
How do you prevent cuterebra in cats?
The best defense against Cuterebra infections for cats is to keep them inside all the time. Outdoor cats may encounter Cuterebra larvae while hunting small mammals. If the cat does venture outside, make sure to frequently examine him for symptoms of edema. If you see something strange, get in touch with your vets.
All cats should get routine health checkups, usually once or twice a year. By doing these examinations, your veterinarian can detect a cerebral lesion or cure it before your cat becomes symptomatic.
