| emerging bacterial zoonotic and vector-borne diseases. ecological and epidemiological factors. | among the etiologic agents of emerging infectious diseases are several bacterial organisms that naturally reside in animal and arthropod hosts. the most compelling emerging bacterial zoonotic and vector-borne diseases in the united states are lyme disease; a southern erythema migrans-like illness; human monocytic ehrlichiosis; human granulocytic ehrlichiosis; a novel cat flea-associated typhus group rickettsiosis; bartonelloses of immunocompetent and immunocompromised persons, particularly with ... | 1996 | 8627968 |
| [the state of in vitro breeding of lice and fleas] | laboratory breeding of lice, fleas and other bloodsucking arthropods is necessary for developing and testing the efficacy of new drugs and alternative arthropod control methods. they are necessary to investigate their role as vectors of pathogens and to develop methods for diagnosis and therapy of arthropod caused or transmitted diseases. to date, it is not possible to replace rabbits as natural blood sources for breeding lice colonies (pediculus spp.). but on the base of the knowledge about lic ... | 1996 | 11178453 |
| effect of combing time on cat flea (ctenocephalides felis) recovery from dogs. | combing the haircoat to count fleas has been used to determine the efficacy of insecticides against fleas on dogs, but no standardization of method has been reported. in this study, the effect of combing time on flea recovery from dogs was examined. six beagle dogs were infested with 100 unfed, adult ctenocephalides felis (bouché) on each of three consecutive days. a crossover design, balanced for carryover effects, was used to evaluate flea removal rates from each dog by comb-counting for three ... | 1995 | 8644450 |
| disinfestation of experimentally infested cat fleas, ctenocephalides felis, on cats and dogs by oral lufenuron. | in vivo efficacy of orally administered lufenuron, an insect growth regulator, in disinfesting cat fleas was evaluated, using flea-free cats and dogs which were purchased and infested every 10 days with cat fleas from a colony kept in our laboratory. lufenuron was orally administered as a single dose of 15, 30, or 60 mg/kg to cats, and 5, 10 or 20 mg/kg to dogs. in cats, adult flea emergence was intensively prevented for 30 days by dosing of 15 mg/kg of lufenuron and 40 days by 30 or 60 mg/kg. t ... | 1995 | 8519893 |
| the cat, the flea, and pesticides. | recent advances in our knowledge of cat flea biology and the discovery of new nontoxic control methods have greatly simplified and improved flea control. instead of relying on adulticides for the bulk of flea control, the veterinarian now focuses on the immature stages, particularly the larvae and the eggs. by doing this, environmentally "friendly" flea control methods are employed that are much safer for the veterinarian, the pet owner, and the cat. | 1995 | 8525567 |
| airborne insecticide residues after broadcast application for cat flea (siphonaptera: pulicidae) control. | airborne residues of chlorpyrifos, propetamphos, and permethrin were measured up to 50 h after broadcast treatment for cat flea, ctenocephalides felis (bouché), control in residences. type of insecticide, time after treatment, ventilation regime, and height above floor significantly affected airborne residues. before spraying chlorpyrifos, residues were low or undetected. in nonventilated residences, chlorpyrifos residues peaked 0-6 h after treatment at 38 ng/liter, then slowly declined through ... | 1995 | 8537544 |
