Abstract: A lytic virus specific for a target strain of a microorganism and substantially free of undesirable genes may be utilized in processes including control of populations of microorganisms. The virus may include a host-range mutant, or “h-mutant.” A method for generating virus includes growing virus-resistant variants of a target strain of a microorganism in the presence of viruses that are specific for the target strain. Only h-mutant viruses will proliferate. Wild-type virus-resistant and virus-resistant variants of a microorganism are also disclosed, as are methods generating such variants. Methods for controlling target strain microorganisms include introducing virus into a treatment site where control of a population of a target strain microorganism is desired or introducing virus-resistant variants of a microorganism into treatment sites where the presence of the microorganism is desired.

Abstract: Methods for disinfecting external layers from animals include applying phage to the external layers. Phage may be applied before an external layer is removed from a remainder of an animal's body, during the removal process, or following removal of the external layer from the remainder of the animal's body.

Abstract: There is provided a security mailbox for receiving mail and securely retaining the mail until removed by the mailbox owner. Outgoing mail may be placed in the mailbox and retained out of sight until accessed by the mail carrier. A visual indicator is provided to signal the presence of outgoing mail. Once mail has been deposited in the mailbox and secured within, additional mail may not be placed in the mailbox until the mailbox owner has unlocked and reset the mailbox. Another visual indicator signals the mailbox owner that mail has been deposited in the mailbox. The mailbox is sized to receive small packages such as boxes of checks from a check printer, packages of medications, and the like.
