Nesfatin-1 is an anorexic peptide derived from a precursor, nucleobindin-2 (NUCB2), which is distributed in various organs, coexists with ghrelin in the gastric X/A-like cells and closely relates to an appetite control in rodents and humans. Nesfatin-1 may be a significant factor addressing the satiety also in veterinary medicine, however, there are few reports about nesfatin-1 in dogs. In the present study, we detected canine NUCB2/nesfatin-1 mRNA in various tissues, especially abundant in pancreas, gastrointestinal tracts, testis and cerebellum. We examined circulating nesfatin-1 concentrations and NUCB2/nesfatin-1 mRNA expressions in upper gastrointestinal tracts (gastric corpus, pyloric antrum and duodenum) in dogs fed on different types of diets. Plasma nesfatin-1 concentrations in the dogs were approximately 4 ng/ml and they did not change after feeding through the study, however, NUCB2/nesfatin-1 mRNA expressions in pyloric antrum were 1.84-fold higher in the dogs fed on a High fiber/High protein diet (P<0.001), 1.48-fold higher in the dogs fed on a High fat/Low protein diet (P<0.05) and 1.02-fold higher in the dogs fed on a Low fat/High carbohydrate diet (not significant) comparing to those on a control diet. It was concluded that High fiber/High protein and High fat/Low protein diets increased NUCB2/nesfatin-1 production in canine gastrointestinal tracts. These results may set the stage for further investigations of canine NUCB2/nesfatin-1, which may relate to satiety effects in dogs.

Both calcined shell calcium, which was recently reported to have bactericidal effects on Escherichia coli O157 : H7, Pseudomonas aeruginosa, and Staphylococcus aureus, and calcium oxide, which is the main component in calcined shell calcium, were examined as a bactericide against Legionella species. A calcined shell calcium solution of 0.025% or above reduced L. pneumophila counts from the original 7.0 × 106 CFU/ml to less than 300 CFU/ml after an incubation period of 1 hr. In water samples taken from the cooling tower of a prefabricated house, a calcined shell calcium solution of 0.05% or above reduced L. pneumophila counts to less than 10 CFU/ml after an incubation period of 1 hr. There was no difference between the bactericidal effects of the calcined shell calcium manufactured from the shells of surf clams and that manufactured from oysters; surf clams and oysters are equally effective. Calcium oxide also showed similar bactericidal effects against L. pneumophila, and thus we believe that the effect is not specific to calcined shell calcium, but rather to effects caused by the alkalinity of calcium oxide. The use of calcium oxide or calcined shell calcium as a bactericidal agent against Legionella species in the cooling tower water of hotels or other buildings is therefore expected.
