Gastrointestinal nematode burden in working equids from humid tropical areas of central Veracruz, Mexico, and its relationship with body condition and haematological values.

摘要: The east coast of Veracruz, Mexico, has an important equine population used for working in rural production systems. objectives this study were (1) to calculate the prevalence tropical equids (donkeys, mules and horses) infected with gastrointestinal nematodes (GINs) GINs involved, (2) measure body condition score (BCS) haematological values each equid its relationship faecal worm egg count (EPG). One hundred forty randomly selected from five different villages along central state Veracruz blood samples obtained animal. Gastrointestinal parasite burdens determined using McMaster technique. Packed cell volume, total plasma proteins, red white measured sample. Prevalence was higher than 90 %. Mules had highest median counts (875 EPG), followed by horses donkeys 400 EPG. There no correlation between EPG BCS or (p > 0.05). Results suggest that despite high burdens, involved trial are not being seriously affected. This provides information which might help designing future strategies control nematode infections Mexican tropics; more emphasis should be placed on other inputs (nutrition perhaps), individual anthelminthic treatment those animals when signs present themselves.
