«We had some clues that
oral secretions of beetles suppressed defenses, but no one had followed up on that research.»
According to Felton, the beetles do not have salivary glands and so they
regurgitate oral secretions onto the leaves to begin digestion.
Surprisingly, the application of
larval oral secretions inhibited the transduction of calcium signals to neighboring leaves in the experiment.
Cats can be infected by direct contact with nasal and
oral secretions of infected cats or dogs.
The bacteria can be transmitted through nasal and
oral secretions and also picked up if the animal sneezes or coughs.
Transmission: Calicivirus is easily transmitted through direct contact with nasal or
oral secretions.
During these recurrences, infected cats shed the virus profusely in their eye, nasal, and
oral secretions, increasing the risk of infecting other cats.
