Molecular Detection of Anaplasma phagocytophilum from Larvae of Haemaphysalis longicornis in Ibaraki, Japan.

We collected 1,084 ticks by flagging vegetation in Tsukuba and Moriya (Ibaraki, Japan), where several cases of canine granulocytic anaplasmosis were reported. The DNA of the collected ticks was molecularly examined for infection with the family Anaplasmataceae. Twenty-six positive samples of Anaplasmataceae-specific PCR of partial 16S rRNA gene were subjected to semi-nested PCR, covering the divergent regions, the gene, and sequence analysis.

Subclinical Infections of Anaplasma phagocytophilum and Anaplasma bovis in Dogs from Ibaraki, Japan.

We evaluated the prevalence of Anaplasma infection in 332 dogs from Ibaraki, Japan, using serological and molecular methods. An immunofluorescence antibody assay against Anaplasma phagocytophilum indicated that 7 of the 328 serum samples tested (2.1%) were positive for A.

First Molecular Detection and Phylogenetic Analysis of Anaplasma phagocytophilum from a Clinical Case of Canine Granulocytic Anaplasmosis in Japan.

Anaplasma phagocytophilum DNA was detected from a dog with canine granulocytic anaplasmosis (CGA) in Japan. Phylogenetic analysis of the DNA using 16S rRNA, gltA, and groEL sequences revealed that the strain was nearly identical to A. phagocytophilum detected from Apodemus agrarius (black-striped field mouse) in China and Korea.

Canine serum thermostable alkaline phosphatase isoenzyme from a dog with hepatocellular carcinoma.

A dog histopathologically diagnosed with hepatocellular carcinoma (HCC) showed very high serum alkaline phosphatase (ALP) activity. A supernatant of ascitic fluid and tumor tissue extracted from the dog also showed much higher ALP activity than normal. ALP isoenzyme analysis of samples was performed using polyacrylamide gel disk electrophoresis, and a wide, broad abnormal band was observed.
