Field trial on the therapeutic efficacy of paromomycin on natural Cryptosporidium parvum infections in lambs

AbstractThe objective of this study was to evaluate the therapeutic efficacy of paromomycin against cryptosporidiosis in naturally infected lambs under field conditions. The 36 cross-bred neonatal lambs, 3–10 days old, were used. On the first day that lambs showed diarrhea (Day 1) they were randomly divided into three groups. The infected control group (14 lambs) remained unmedicated whereas the two other groups were orally medicated with paromomycin solution (Humatin®, Parke Davis, France): 12 lambs (Group A) at 100 mg/kg per day for three consecutive days (Days 1–3) and 10 lambs (Group B) at 200 mg/kg per day for two days (Days 1 and 2). Drug efficacy was assessed by evaluating the presence of diarrhea, oocyst shedding and weight gains from Days 1 to 23. The results show the efficacy of paromomycin in reducing both cryptosporidial oocyst output and severity of clinical signs. On Day 4, all unmedicated lambs remained infected and excreted large numbers of cryptosporidial oocysts (mean score: 2.5) whereas oocyst output had stopped in most medicated lambs (>60%) and low numbers of oocysts were excreted in the remaining lambs (mean score: 0.45 in Group A and 1 in Group B). Mean oocyst excretion was significantly reduced in medicated lambs from Days 2 to 5 (P<0.05). Treatment also reduced, but not completely prevented, clinical symptoms although diarrhea stopped in most medicated lambs just after drug withdrawal. The mean weight gains of Group A lambs were higher than that of unmedicated lambs throughout the study and statistically significant differences were found from Days 1 to 11 (1.99±0.81 versus 1.47±0.53) (P<0.05). By contrast, the growth rate of Group B lambs from Days 11 to 23 was impaired when compared with the two other groups (P<0.05) although no significant differences were found at the end of the study (Days 1–23).
