Disclosed is a method for preventing the transmission of an ectoparasite-borne pathogen to a mammal exposed to predation by the ectoparasite, wherein a time delay exists between attachment of the ectoparasite to the mammal and transmission of the pathogen from the ectoparasite to the mammal. The method comprises applying to the mammal an ectoparacide to kill the ectoparasite in place on the mammal, without necessarily finding or mechanically detaching the ectoparasite, at a time after the exposure of the mammal to the ectoparasite, and within the time delay, thereby preventing transmission of the pathogen from the ectoparasite to the mammal. |

DETAILED DESCRIPTION The invention provides a method for preventing the transmission of an ectoparasite-borne pathogen to a mammal exposed to predation by the ectoparasite, wherein a time delay exists between attachment of the ectoparasite to the mammal, and transmission of the pathogen from the ectoparasite to the mammal.
The method comprises applying to the mammal an ectoparacide to kill the ectoparasite in place on the mammal, without necessarily finding or mechanically detaching the ectoparasite, at a time after the exposure of the mammal to the ectoparasite, and within the time delay, thereby to prevent transmission of the pathogen from the ectoparasite to the mammal.
The invention may be utilized in a wide range of applications to prevent a wide range of mammalian diseases caused by the transmission of ectoparasite-borne pathogens, wherein a delay exists between the attachment of the ectoparasite to the mammal and pathogen transmission from the ectoparasite to the mammal.
The ectoparacide comprises a composition which is applied in a sufficient concentration to promptly kill the attached ectoparasite at a time after ectoparasite attachment to the mammal and before pathogen transmission.
The ectoparacide also may comprise any of a range of possible delivery vehicles including but not limited to, e.
g.
, a soap or a cream.
The ectoparacide may be applied, e.
g.
, directly, or, alternatively, as a spray, or utilizing any of a wide range of possible application methods available in the art.
In one embodiment, the ectoparacide may comprise a soap, and may be applied by washing the mammal with the soap.
Any of a wide range of possible insecticidal soaps available in the art may be utilized (e.
g.
, U.
S.
Pat.
No.
4,707,496).
In one embodiment, the soap conveniently can be rinsed off after just a short period of time.
When the mammal is periodically exposed to predation by the ectoparasite, the applying step may be repeated within the time delay after each periodic exposure.
The method of the invention successfully prevents pathogen transmission without the necessity of either finding or removing the ectoparasite
