Retrospective study of clinical and laboratory findings of autosomal recessive cholesterol deficiency in Holstein calves in Japan
Provedor de dados: 19
Autores: Inokuma, Hisashi; Horiuchi, Noriyuki; Watanabe, Ken-ichi; Kobayashi, Yoshiyasu.
This retrospective study was conducted to clarify the clinical findings of an autosomal recessive cholesterol deficiency disorder in Holstein calves. Thirty-three calves with poor growth by uncertain causes from 2007 to 2016 comprised the study population of calves that were homozygous (n = 12) and non-homozygous (n = 21) for the disease. No significant group-dependent differences were found in the proportion with diarrhea or fever. Fewer calves with ataxia and anorexia were found in homozygotes. All affected calves showed muscular atrophy. Median RBC, Hb, and Ht values in affected calves were significantly lower. Median total cholesterol (TC) in homozygotes was extremely low, at 6.5 mg/dl (range, 5.0-15.0). TC readings under 10 mg/dl were thought to be...

Serological methods were utilized to detect Anaplasma and Ehrlichia infection in domestic animals in Xinjiang Uygur Autonomous Region, China. By using an indirect immunofluorescence assay (IFA), antibodies that reacted with Anaplasma phagocytophilum and Ehrlichia chaffeensis were detected mainly in ruminants kept on pastureland in Altai, Ili and Kashgar area. Antibody titers up to 1:320 were recorded. These results indicate that ruminants kept in these areas may be infected with some species of Anaplasma and Ehrlichia.

Pericardial mesothelioma with severe congestive heart failure in a Holstein cow
Provedor de dados: 19
Autores: Suzuki, Haruka; Watanabe, Ken-ichi; Horiuchi, Noriyuki; Kobayashi, Yoshiyasu; Inokuma, Hisashi.
A 58-month-old Holstein cow showed anorexia, edema of the lower jaw and dewlap, jugular venous engorgement, abdominal gas, and watery diarrhea. Heart sounds were faint on auscultation, and decreased rumen motility was noted in physical examination. Echocardiography findings included adhesion of fibrin-like structures to the pericardium, highly echogenic periaortic region, and pericardial effusion, which suggested traumatic pericarditis or tumor formation. Although atypical mesothelial cells were observed in bloody pericardial fluid, no diagnosis was made. At complete necropsy, milky mass formation was observed on the epicardium. Histopathological examination led to a diagnosis of primary malignant pericardial mesothelioma. © 2017, Hokkaido University. All...

Clinical usefulness of antibodies against Babesia gibsoni detected by ELISA with recombinant P50
Provedor de dados: 19
Autores: Miyama, Takako; Inokuma, Hisashi; Itamoto, Kazuhito; Okuda, Masaru; Verdida, Rodolfo A.; Xuan, Xuenan; 猪熊, 壽; 玄, 学南.
The clinical usefulness of antibodies against Babesia gibsoni detected by ELISA with recombinant P50 was examined in dogs in an area where B. gibsoni infection was endemic. Only 8 among 14 dogs with acute type B. gibsoni infection without a previous history of infection were positive. This high percentage of false-negative results is thought to be a weak point of ELISA as a diagnostic tool. However, 14 other anemic dogs with a confirmed history of B. gibsoni infection were all positive, thus confirming the higher sensitivity of ELISA in detecting a history of infection.

Provedor de dados: 19
Autores: Ybañez, Adrian Patalinghug; Ybañez, Rochelle Haidee D.; Claveria, Florencia G.; Cruz-Flores, Mary Jane; Xuenan, Xuen; Yokoyama, Naoaki; Inokuma, Hisashi.
A total of 658 cattle in 6 provinces in the Philippines were screened for Anaplasma marginale infection by using a diagnostic heat-shock operon (groEL) gene-PCR assay. The screening-positive samples were further tested using the major surface antigen protein 1a (Msp1a) gene-PCR assay. Screening PCR results showed 130 cattle (19.8%) were positive for the A. marginale infection. Subsequent amplification using the Msp1a gene only showed 93 samples (14.1%) to be positive. In addition, 37 tandem-repeat structures, including 20 novel structures, and 41 distinct genotypes were identified. Interestingly, multiple infections of 4 different genotypes were also observed in A. marginale-infected cattle. The present study demonstrated the prevalence and...

Anaplasma species of veterinary importance in Japan
Provedor de dados: 19
Autores: Ybañez, Adrian Patalinghug; Inokuma, Hisashi.
Anaplasma species of the family Anaplasmataceae, order Rickettsiales are tick-borne organisms that can cause disease in animals and humans. In Japan, all recognized species of Anaplasma (except for Anaplasma ovis) and a potentially novel Anaplasma sp. closely related to Anaplasma phagocytophilum have been reported. Most of these detected tick-borne pathogens are believed to be lowly pathogenic in animals in Japan although the zoonotic A. phagocytophilum has recently been reported to cause clinical signs in a dog and in humans. This review documents the studies and reports about Anaplasma spp. in Japan. c Ybanez and Inokuma.

DNA fragments of 'Candidatus Mycoplasma haemominutum', a feline heamobartonella pathogen, were detected from unfed Ixodes ovatus collected from vegetation in Hokkaido, Fukushima and Yamaguchi Prefectures, and unfed Haemaphysalis flava in Yamaguchi Prefecture. This finding suggests that ixodid tick is a possible vector of 'C. Mycoplasma haemominutum'. Spiroplasma DNA was also detected from unfed I. ovatus in Hokkaido, Fukushima and Yamaguchi Prefectures. The analysis of nucleotides sequence suggested that this Spiroplasma was distinct from registered species.

Autores: Watanabe, Malaika; Oikawa, T; Hiraoka, Hiroko; Kaneko, N; Itamoto, Kazuhito; Mizuno, Tohru; Okuda, Masaru; Inokuma, Hisashi; 猪熊, 壽.
Three beagle dogs were inoculated with mice spleen/liver homogenate infected with Ehrlichia species detected from Ixodes ovatus (EIO) and one dog was used as a control. All three infected dogs did not show clinical signs of disease except for mild pyrexia throughout the 41-day study period. Splenomegaly was observed from Day 7 post-inoculation (p.i.) in two of the dogs. Hematological and biochemical abnormalities included mild thrombocytopenia, hypoproteinaemia, hypoalbuminaemia and increased C-reactive protein values. One of the dogs' splenic aspirate sample was PCR-positive for Ehrlichia Day 7 p.i. and another dogs' blood and bone marrow aspirate sample was PCR-positive Day 41 p.i. Sequence analysis of the PCR products showed 100% homology with the...

Provedor de dados: 19
Autores: Sashika, Mariko; Abe, Go; Matsumoto, Kotaro; Inokuma, Hisashi; 松本, 高太郎; 猪熊, 壽.
Rickettsial infection in feral raccoons (Procyon lotor) in Hokkaido, Japan was analyzed by molecular methods. Genus-specific nested polymerase chain reaction (PCR) analysis based on the Rickettsia citrate synthase (gltA) gene showed that 13 of 699 raccoons (1.9%) examined were positive for Rickettsia. Twelve of the 13 partial gltA sequence amplicons were successfully analyzed. The nucleotide sequence of one amplicon was identical to both Rickettsia heilongjiangensis and R. japonica, one was identical to R. felis, and the rest to R. helvetica. This is the first report on the detection of rickettsial agents in peripheral blood of raccoons.

Provedor de dados: 19
Autores: Hiraoka, Hiroko; Shimada, Yojiro; Sakata, Yoshimi; Watanabe, Malaika; Itamoto, Kazuhito; Okuda, Masaru; Masuzawa, Toshiyuki; Inokuma, Hisashi.
Ticks removed from 1136 dogs and 134 cats all over Japan were examined for Borrelia infection by PCR and sequencing. The 5S-23S rDNA intergenic spacer of Borrelia was detected from two Ixodes persulcatus ticks from two dogs and two unidentified Ixodes spp. from another two dogs in Hokkaido, and two Ixodes granulatus ticks from two cats in Okinawa. Additional 2 I. granulatus from the same cats also showed positive. Sequence analysis of the PCR products revealed that the one from Hokkaido was similar to B. garinii, the three from Hokkaido to B. tanukii, and the four from Okinawa to a novel Borrelia sp. closely related to B. valaisiana. The data was confirmed by analysis of the flagellin gene sequence. Infected ticks carried by companion animals can be...

Provedor de dados: 19
Autores: Kondoh, Daisuke; Kawano, Tomomi; Kikuchi, Tomoaki; Hatate, Kaoru; Watanabe, Kenichi; Sasaki, Motoki; Yamagishi, Norio; Inokuma, Hisashi; Kitamura, Nobuo.
Background: Laterality disorders of the abdominal organs include situs inversus totalis that mirrors the arrangements of all internal organs and heterotaxy syndrome (situs ambiguus) in which the thoracic or abdominal organs are abnormally arranged. Heterotaxy is often accompanied by multiple congenital malformations, and it generally comprises asplenia and polysplenia syndromes. To our knowledge, polysplenia syndrome has been reported in only three cattle, and computerized tomographic (CT) images of these animals were not obtained. Case presentation: A six-month-old Holstein heifer had ruminal tympani and right abdominal distension. CT imaging showed that the rumen occupied the right side of the abdominal cavity, the omasum and abomasum occupied the left...

Autores: Adrian Patalinghug Ybañez; Rochelle Haidee Daclan Ybañez; Yokoyama, Naoaki; Inokuma, Hisashi.
Aim: Anaplasma platys, the causative agent of infectious canine cyclic thrombocytopenia, is a tick-borne pathogen that also has been implicated as potentially zoonotic. To provide molecular evidence on the multiple infections of A. platys variants in Philippine dogs. Materials and Methods: DNA fragments of A. platys from infected dogs in the Philippines were molecularly characterized. For screening, 25 dogs suspected to have canine anaplasmosis were tested using a 16S rRNA-based nested polymerase chain reaction (PCR). Infection was confirmed by sequencing of positive amplicons. Second round PCR targeting a longer 16S rRNA fragment was subsequently performed on the first round PCR amplicons of the positive samples. Further characterization using the...

Provedor de dados: 19
Autores: Sakamoto, Leo; Ichikawa, Yasuaki; Sakata, Yoshimi; Matsumoto, Kotaro; Inokuma, Hisashi; 松本, 高太郎; 猪熊, 壽.
The prevalence of Ehrlichia and Anaplasma in 1,427 dogs from 32 Japanese prefectures was evaluated by PCR and DNA nucleotide sequencing. PCR screening demonstrated that 18 dogs (1.3%) were positive for Anaplasmataceae. Sequence analysis revealed that 14 of the amplicons were most closely related to Wolbachia spp., symbionts of Dirofilaria immitis, whereas three were identified as Anaplasma bovis. The remaining amplicon could not be sequenced. Almost the entire sequence of 16S rRNA (1,452 bp) from one of the positive specimens was determined, and subsequent phylogenetic analysis confirmed that the detected sequence was that of A. bovis. This is the first detection of A. bovis DNA fragments in dogs. Species-specific nested PCR showed that 15 (1.1%) of the...

Autores: Sasaki, Hiromi; Goyama, Takashi; Noda, Yoichiro; Matsumoto, Kotaro; Kobayashi, Yoshiyasu; Inokuma, Hisashi; 松本, 高太郎; 古林, 与志安; 猪熊, 壽.
A 2-month-old male Holstein calf showed clinical signs of abdominal bloating, melena, and pain and was suspected of having a perforating abomasal ulcer. Necropsy revealed a large mass located preferentially around the abomasum and a large perforating abomasal ulcer on the pyloric antrum. Milky white masses of various sizes were also found in the abdominal cavity that consisted of agglutinated nodules ranging in size from a pinhead to a golf ball and were distributed on the surfaces of the liver, reticulum, omasum, abomasum, and diaphragm. Microscopic examination revealed that the masses were composed primarily of hyaline matrices, epithelioid tumor cells, and large atypical cells with hyaline droplets and/or vacuoles. Stromal hyaline matrices and hyaline...
