Curriculum for Youth

Dr. Chantel Wilson, a 4-H STEM Specialist from Virginia State University, has developed a curriculum using stuffed animals and other fun stuff to teach youth about internal parasites in goats and sheep. To learn more about her innovative curriculum, contact her at

Intensity of Parasitic Infections

Chinese researchers conducted a study to compare the infection intensity of gastrointestinal parasites on farms with different feeding and management regimes: confinement (indoors), semi-confinement (3-4 hr grazing per day), and grazing (semi-desert grassland/rangeland). Two farms from each type were included in the study. Thirty young sheep (6-12 months) from each farm were sampled for fecal egg count (FEC). There was a statistical difference in FEC among the three regimes. EPG was low in confinement, moderate in semi-confinement, and high in grazing. Teladorsagia (Ostertagia) was the primary worm species; Haemonchus sp. was less prevalent. While OPG counts were numerically different -- h

TST vs. Whole Flock Treatment

Researchers in Ontario, Canada, reported on a study in which they compared whole flock treatments (WT) vs. targeted selective treatment (TST) of periparturient ewes. Six client-owned farms were utilized in the study. On the whole treatment farms (n=3), all of the ewes were treated with an anthelmintic at lambing (closantel @10 mg/kg). On the TST farms (n=3), ewes were only treated if they met at least one of four criteria: 1) the last grazing season was the first grazing season; 2) body condition score <2; 3) FAMACHA© score >4; or 4) nursing 3 or more lambs. The number of animals treated on TST farms was reduced by as much as 47 percent. Parasite burdens were higher on TST farms, but fecal

Bacteria Eats Parasitic Worms

Scientists at the University of Glasgow have discovered a new bacteria that eats parasitic roundworms from the inside out. Before roundworms attack their final host – an animal or a human – they first feed on bacteria as they develop. Usually those bacteria are disabled before they reach the parasite's stomach, making them harmless. But Chryseobacterium nematophagum not only survives, it fights back. The scientific name the scientists chose for the new bacteria means “golden bacteria, nematode-eating.” C. nematophagum bacteria could prove very useful in helping control the spread of such worms (or nematodes) in plants, animal livestock, and even human beings.
