seasonal transmission of fasciola hepatica in north central florida (u.s.a.).to assess seasonal transmission of fasciola hepatica 37 groups of fluke-free tracer sheep, one group of four sheep each month in succession, grazed an infected pasture in north central florida (u.s.a.) from june 1984 to june 1987. at the end of each month, tracers were moved to a fluke-free barn for 2 months, then necropsied and flukes counted. fluke transmission mostly occurred during the first half of the year, with peak transmission from february to april. no transmission occurred during the ...19902228432
the prevalence of fasciola hepatica in its snail intermediate host determined by dna probe assay.accurate snail intermediate host infection prevalence data have the potential to be extremely useful in determining seasonal transmission dynamics of fasciola hepatica. because the microscopic techniques currently used lack the sensitivity and specificity necessary to obtain meaningful infection prevalence data, we developed a highly accurate and efficient dna probe assay. the assay has a sensitivity of 100%, a specificity of > 99%, easily detects a single miracidia and does not cross-hybridize ...19979467746
efficacy and safety of clorsulon used concurrently with ivermectin for control of fasciola hepatica in florida beef cattle.the safety and anthelmintic efficacy of clorsulon (7 mg/kg of body weight, orally) given concurrently with ivermectin (0.2 mg/kg, subcutaneously) for control of fasciola hepatica were evaluated in 75 crossbred beef cattle. twenty-three control animals were given only ivermectin. fluke egg counts were significantly lower (p less than 0.0001) in clorsulon-treated animals by day 14 after treatment than before treatment (base line) and were significantly lower (p less than 0.005) after treatment in ...19853839640
effects of hexachlorethane on the milk yields of dairy cows in north florida infected with fasciola hepatica.hexachlorethane was evaluated as a fasciolicide in dairy cattle under field conditions. after treatment with hexachlorethane, fasciola hepatica-infected cows had a significant (p = 0.05) average daily milk yield increase (90 to 120 days after treatment) of + 4.2 kg/day (+ 5.0 kg/day for single treatment and + 4.0 kg/day for double treatment) over daily yields of the previous lactation. nontreated controls and noninfected treated animals did not have significant gains over yields of the previous ...19807369597
