Three strains of chicken anemia virus (CAV) were detected in 11 to 14-weeks old chickens, showing depression, wasting, and increased mortality, from three farms in eastern Japan. Another strain was detected in 12-weeks old chickens from one farm without clinical signs. Bacterial infections were suggested in three farms with clinical signs and its involvement in the occurrence of the diseases might be suspected. Sequence analysis of the VP1, VP2, and VP3 genes of four CAV strains revealed that the three from farms with clinical signs belonged to genotype A2, whereas that from the apparently-normal farm belonged to A3. This may be a rare case report about the diseases suspected of the involvement of the CAV infection in older birds.

Ascitic feline coronavirus (FCoV) RNA was examined in 854 feline infectious peritonitis (FIP)-suspected cats by RT-PCR. The positivity was significantly higher in purebreds (62.2%) than in crossbreds (34.8%) (P<0.0001). Among purebreds, the positivity in Norwegian Forest Cat (92.3%) and Scottish Fold (77.6%) were significantly higher than the average of purebreds (P=0.0274 and 0.0251, respectively). The positivity was significantly higher in males (51.5%) than in females (35.7%) (P<0.0001), whereas no gender difference has generally been noted in FCoV antibody-prevalence, indicating that FIP more frequently develops in males among FCoV-infected cats. Genotyping was performed for 377 gene-positive specimens. Type I (8.3%) was far more predominantly detected than type II (10.6%) (P<0.0001), similar to previous serological and genetic surveys.

Induction of mucosal immune responses against Porphyromonas gingivalis within the oral cavity of dogs was studied by immunizing with pH-sensitive fusogenic polymer (MGluPG)-modified liposome-associated cell lysate. Dogs immunized with P. gingivalis cell lysate-containing MGluPG-modified liposomes by intraocular (eye drop) route displayed significant levels of P. gingivalis cell lysate-specific serum IgG and IgA as well as mucosal IgA antibodies in saliva secretion. Serum and salivary antibodies generated by intraocularly immunized with MGluPG-modified liposome-associated P. gingivalis cell lysate revealed a significant aggregation activity against P. gingivalis, whereas serum and saliva from dogs receiving MGluPG-modified liposomes unentrapping P. gingivalis cell lysate did not show the aggregation activity against P. gingivalis. Furthermore,P. gingivalis-specific antibodies in saliva of immunized dogs inhibited the adherence of P. gingivalis to cultured HeLa cells. More importantly, salivary antibodies induced by intraocular immunization with P. gingivalis cell lysate-containing MGluPG-modified liposomes significantly inhibited the coaggregation of P. gingivalis with A. naeslundii and the cell damage activity of P. gingivalis against FaDu cells, an oral epithelial cell. These results suggest that intraocularly administered P. gingivalis cell lysate-containing MGluPG-modified liposomes should be an effective mucosal vaccine against P. gingivalis infection in dogs and may be an important tool for the prevention of periodontitis.

A 7-year-old spayed female domestic short-haired cat presented with dysuria and hematuria that had been unresponsive to medical therapy. Imaging tests such as ultrasonography, urethrocystography and computed tomography revealed a pelvic mass compressing the urethra. Based on histological examination of the mass following surgical resection, the cat was diagnosed squamous cell carcinoma (SCC) derived from the uterine remnant. After surgery, dysuria was resolved, but on instead, urine and fecal incontinence were observed. Then, about four months after surgery, recurrence of the mass and the symptoms was observed. Consequently, the cat was ultimately euthanized. This is the first report of SCC arising from the uterine remnant in a spayed female cat.
