Parasites + English

  • Heartworm treatment involves several components to combat potential bacterial infection, kill heartworm larvae (microfilaria), kill adult heartworms, and then test to confirm successful treatment. Complete rest for a dog undergoing treatment is essential.

  • Hepatozoonosis in dogs is caused by ingestion of one of two organisms: H. americanum and H. canis. Both parasites are more common in the southern United States. The clinical sign and treatments for dogs with hepatozoonosis differ depending on the parasite species causing the infection. In either case, with appropriate treatment, the prognosis is generally good.

  • Imidocarb dipropionate is an injectable medication that is administered by a veterinarian to treat babesiosis in dogs. It is also used off-label to treat other protozoal infections in dogs, cats, and horses. Most common side effects include mild drooling, tearing, vomiting, or nasal drip. Do not use in pets with exposure to cholinesterase-inhibiting drugs, pesticides, or chemicals. If a negative reaction occurs, please call your veterinary office.

  • Ivermectin + pyrantel is a heartworm disease preventive that treats and controls hookworms and roundworms in dogs. Ivermectin + pyrantel is given by mouth as a flavored chew tablet. At prescribed doses, ivermectin + pyrantel is well-tolerated. Some dog breeds (e.g., collies, sheepdogs, and collie- or sheepdog-cross breeds) are more sensitive to ivermectin than others; your veterinarian will advise you on the safety of using this medication in your dog. If you suspect an overdose or an adverse reaction to the medication, call your veterinary office immediately.

  • Ivermectin + pyrantel + praziquantel is a combination of anti-parasitic medications used to prevent heartworms and control roundworm, hookworm, and tapeworm in dogs. It is given by mouth as a flavored chew tablet. At prescribed doses, this product is generally well-tolerated but some dogs may experience decreased appetite, vomiting, diarrhea, or burping. Certain drugs may interact with those in this combination product; it is extremely important to let your veterinarian know about any medications or supplements that your pet is taking. If your dog has an adverse reaction to this product, call your veterinary office immediately.

  • Platynosomiasis is a disease caused by a parasitic worm called a liver fluke. It affects cats in tropical and subtropical regions. The lifecycle is complex and involves several hosts. Cats can become infected by ingesting lizards or amphibians that have the larval stages of the fluke. The flukes live in the bile ducts and gall bladder of affected cats, causing symptoms of liver disease.

  • Liver fluke (Heterobilharzia americana) is a parasitic worm that affects dogs in the southern Atlantic and Gulf states and causes a disease called schistosomiasis. The fluke’s lifecycle is complex and involves a freshwater snail. Dogs can become infected by swimming or wading in water that has the larval stages of the fluke. The flukes cause granulomas (inflammatory nodules) to form in the liver, intestines, and other abdominal organs. Symptoms of gastrointestinal and liver disease may be present.

  • Lotilaner + moxidectin + praziquantel + pyrantel (brand name Credelio Quattro®) is a combination antiparasitic used to protect against ticks, fleas, heartworm disease, roundworms, hookworms, and tapeworms in dogs and puppies 8 weeks of age and older and weighing at least 3.3 lb (1.5 kg). It comes in a chewable tablet to be given monthly. Its use is currently only approved for dogs.

  • In North America, many parasitic lungworms infect cats. Cats can become infected by swallowing infective stages of parasitic lungworm. The exact means of becoming infected varies according to the life cycle of the particular parasite. Signs can include coughing, heavy breathing, wheezing, sneezing, poor appetite or anorexia, weight loss, fever, enlarged lymph nodes, and ocular or nasal discharge, and may be more prominent in kittens due to their immature immune systems. Although the success rate of treatment depends on the severity of symptoms and the number of parasites present, the prognosis for recovery is generally good.

  • Milbemycin oxime + lufenuron is a heartworm disease preventive that also treats internal parasites (e.g., whipworms, hookworms, and roundworms) and controls flea populations in dogs. Milbemycin oxime + lufenuron is given by mouth as a flavored chew tablet. At prescribed doses, this medication is well-tolerated; when used off-label at higher doses for treating mites, side effects have been observed. Your veterinarian will advise you on the safety of milbemycin oxime + lufenuron use in your dog. If you suspect an overdose or an adverse reaction to the medication, call your veterinary office immediately.
