IDENTIFICATION AND CHARACTERIZATION OF Eimeria spp. DURING EARLY NATURAL INFECTION IN GOAT KIDS IN BAJA CALIFORNIA SUR, MEXICO
The aim of this study was to characterize the natural infection by Eimeria spp. in goat kids, and to describe some pathophysiological responses to eimerosis in kids under intensive rearing conditions in B.C.S, Mexico. Nineteen adult crossbred does naturally infected with mixed Eimeria spp. and 20 An...

| description | The aim of this study was to characterize the natural infection by Eimeria spp. in goat kids, and to describe some pathophysiological responses to eimerosis in kids under intensive rearing conditions in B.C.S, Mexico. Nineteen adult crossbred does naturally infected with mixed Eimeria spp. and 20 Anglo Nubian x Creole crossbred kids were used. Oocyst per gram of feces (OPG) and identification of Eimeria species were determined in does (during the pre-kidding and post-kidding periods) and kids. Clinical signs, hematocrit, hemoglobin and alkaline phosphatase activity in blood serum were evaluated. OPG (mean±SD) was significantly higher (P<0.05) in pre-kidding (9,478±7,599) than in post-kidding (5,313±2,909) period. Oocyst elimination in feces began at age 59±9 days in kids. Eimerian species identified were E. arloingi, E. jolchijevi, E. ninakohlyakimovae, E. hirci, E. christenseni and E. alijevi. Kids were humanely sacrificed to evaluate pathological lesions. Intestinal lesions and lesion severity showed differences in duodenum, jejunum, ileum, cecum and colon, being more severe in duodenum. In conclusion, OPG increased during the late pregnancy in does which favored a doe-kid transmission mechanism. Our results support the notion of Eimeria reproduction rhythms during the late pregnancy period in goats, and this reproduction contribute to vertical transmission of Eimeria to the newborn. However, coccidian outbreaks are developed and clinically observed only when stressing factors such as when weaning occur. Coccidia had devastating effects on the intestine of kids, which might cause long-term permanent malabsortion consequences.
