Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
49 words
A medicament for the treatment of the eyes of bovine comprising a biologically inert, bioerodible, nonallergenic, insoluble carrier and an amount of an attenuated strain of Moraxella bovis effective to induce immunity to pinkeye in said cattle, wherein the unattenuated strain of said Moraxella bovis causes pinkeye in bovine.
Claim 2
Dependent Claim
49 words
A medicament for the treatment of the eyes of bovine comprising a biologically inert, bioerodible, nonallergenic, insoluble carrier and an amount of an attenuated strain of Moraxella bovis effective to induce immunity to pinkeye in said cattle, wherein the unattenuated strain of said Moraxella bovis causes pinkeye in bovine.
Claim 3
Dependent Claim
9 words
The medicament of claim 1, which includes an antibiotic.
Claim 4
Dependent Claim
33 words
The medicament of claim 1 or 2 in the form of an ocular insert in which the carrier is release rate controlling material and is permeable to the passage of attenuated Moraxella bovis.
Claim 5
Independent Claim
59 words
The method of inducing in bovine an immunity to pinkeye which is infectious keratoconjunctivitis, comprising applying to the bovine eye which eye has been unaffected by pinkeye disease, a composition comprising an amount of an attenuated strain of Moraxella bovis which is effective to immunize said eye to pinkeye, wherein the unattenuated strain of said Moraxella bovis causes pinkeye.
Claim 6
Independent Claim
59 words
The method of inducing in bovine an immunity to pinkeye which is infectious keratoconjunctivitis, comprising applying to the bovine eye which eye has been unaffected by pinkeye disease, a composition comprising an amount of an attenuated strain of Moraxella bovis which is effective to immunize said eye to pinkeye, wherein the unattenuated strain of said Moraxella bovis causes pinkeye.
Claim 7
Dependent Claim
52 words
The method of claim 4, wherein said composition is in the form of an ocular insert formed of a matrix of a release rate controlling naturally occurring or synthetic material which is biologically inert, bioerodible, non-allergenic and insoluble in tear fluid and wherein said ocular insert is disposed in the conjunctival sac.
Claim 8
Dependent Claim
22 words
The method of claim 4 which further includes the step of treating said eye with an antibiotic prior to applying said composition.
Claim 9
Dependent Claim
40 words
The method of claim 4, wherein the attenuated Moraxella bovis has been attenuated by subjecting unattenuated Moraxella bovis to a heat treatment of serial temperature changes over a range of temperatures of from about 32° C. to about 48° C.
Claim 10
Dependent Claim
38 words
The method of claim 7, wherein the heat treatment is undertaken in two stages wherein in one stage the temperature is decreased to about 32° C. and in another stage the temperature is increased to about 48° C.
Claim 11
Dependent Claim
13 words
The method of claim 7, wherein said attenuated Moraxella bovis is antibiotic dependent.
