Pets and worms and wormers

My friend sent this and I thought I should share it with you all. This is about horse worms but they are the same as dog,cats and other pets get. xxx Kentucky researchers report that roundworms and small strongyles, two common equine intestinal parasites, are developing resistance against most of the commercially available worming products. What's worse, no new drugs against either of these parasites are forthcoming on the market. "Since drug resistance by small strongyles and roundworms has been increasing since the late 1950s, the purpose of this study was to obtain field data regarding the efficacy of commercial wormers to obtain more information on the development of drug resistance," explained Eugene Lyons, PhD, from the University of Kentucky's Gluck Equine Research Center. Drug resistance by small strongyles and roundworms has been increasing since the late 1950s. Between June 1 and December 20, 2007, foals on five farms located in Central Kentucky were monitored in this field study. Efficacy of fenbendazole, oxibendazole, pyrantel pamoate, and ivermectin were evaluated by calculating the reduction in the number of foals with roundworm eggs or small strongyle eggs in their feces before versus after treatment. "Our results showed that there was a significant reduction in roundworm eggs after treatment with fenbendazole and oxibendazole, but not ivermectin or pyrantel pamoate," summarized Lyons. "In addition, only ivermectin reduced the number of small strongyle eggs--the remaining three drugs were ineffective." Lyons explained that while ivermectin still appears to be effective against small strongyles, research using worm count data in addition to egg count data needs to be done in order to evaluate why eggs of these parasites are returning more quickly than previously after treatment. "In this study, we calculated eggs counts only one to two weeks post-worming. This might have been too early and providing misleading information because other studies have suggested that small strongyle eggs counts are returning more quickly than they used to post-treatment," said Lyons. (See Study: Small Strongyles Developing Resistance to Ivermectin for more on this.) Parasite resistance to these drugs is a serious concern for horse owners, veterinarians, and the scientific community in general. The study, "Evaluation of parasiticidal activity of fenbendazole, ivermectin, oxibendazole, and pyrantel pamoate in horse foals with emphasis on ascarids (Parascaris equorum) in field studies on five farms in Central Kentucky in 2007," was published in the July 2008 edition of Parasitology Research.

We raise Llamas and found the same situation, so for 5 years we have been giving diatomaceous earth, that's right the stuff you use in swimming pool filters, but in this case use food grade. You have to go on the internet to find a supply. We add it to our mineral suppliment and not only do we not have a worm problem but we don't have flys in the poop piles. I give a tiny bit to my dog each night and also the cats. The only worwms I have to deal with are tapes from the hunting cats. We also eat a small amount ourselves on our cereal,guess what? no worms. Doctors have found that people who work around animals often get worms and several of our ranchers had a severe problem with this, a Homopathic Doctor put them on this as a medication to elimenate the worms and it worked.

I like that, I knew that for gardening, diatomaceous earth is a regular solution to worm like infestations. It actually grinds the body and they dehydrate. I am so impressed. I could do this with my cats. I have one that stays wormy most all of the time, from the fleas. It would probably work to dust them with as well. Glad I read this response!! Maybe my health food store has it.

It is good to keep your pets vaccinated against these worms. We take our dog yearly for his shots. We also have him on heartguard prevention also to prevent heartworms.

I have a cat that seems to reinfect often. Is there any natural remedy that is helpful?

That's a real shame. Ivermectin and fenbendazole have been around since forever and are the wormers of choice.
