Equine sarcoid of the glans penis with bovine papillomavirus type 1 in a
miniature horse (Falabella)
Kikumi OGIHARA Akikazu ISHIHARA Makoto NAGAI Kazutaka YAMADA Testuya MIZUTANI Mei HARAFUJI Hisanari NISHIO Hiroo MADARAME 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2021,83(6):1016
A 23-year-old Falabella gelding kept in Tochigi, Japan, for more than 20 years presented with a recurrent mass of the glans penis that was first noticed about a year earlier. Partial phallectomy was performed with no adjunctive therapy for local regrowth of the mass. The horse was euthanized 3 months after surgery for urinary retention due to suspected regrowth. The resected mass affected the genital and urethral mucosa of the glans penis, and was diagnosed as equine sarcoid by histopathology and identification of bovine papillomavirus (BPV) DNA. Phylogenetic analysis of the BPV genome of the sarcoid showed high sequence homology to BPV type 1 (BPV-1) from Hokkaido, Japan, suggesting a geographical relationship for BPV-1 in Japan. 相似文献

The present study examined the presence of Babesia parasites in 104 domestic dogs in Nigeria. Sequentially, Babesia parasites infecting domestic dogs underwent genetic and phylogenetic analyses. The results of nested PCR based on the Piroplasmida 18S rRNA gene illustrated that 13.5% (14/104) of the samples were positive. The obtained positive samples determined the nucleotide sequences of the 18S rRNA genes. In the genetic and phylogenetic analyses, four of five nucleotide sequences were similar to Babesia canis rossi, and one sample exhibited a close similarity to a Babesia sp. isolated from a raccoon in Hokkaido, Japan. The present study revealed the widespread presence of B. canis rossi among domestic dogs in Nigeria. 相似文献

The purposes of this study were to examine the relationship between male artificial insemination (AI)
fertility and sperm acrosomal conditions assessed by new and conventional staining techniques and to identify
possible reproductive dysfunctions causing low conception rates in AI using frozen-thawed spermatozoa with
poor acrosomal conditions in Japanese Black bulls. We investigated individual differences among bulls in the
results concerning (1) acrosomal conditions of frozen-thawed spermatozoa as assessed by not merely peanut
agglutinin-lectin staining (a conventional staining technique) but also immunostaining of acrosomal
tyrosine-phosphorylated proteins (a new staining technique), (2) routine AI using frozen-thawed spermatozoa as
assessed by pregnancy diagnosis, (3) in vivo fertilization of frozen-thawed spermatozoa and
early development of fertilized eggs as assessed by superovulation/AI-embryo collection tests and (4)
in vitro fertilization of frozen-thawed spermatozoa with oocytes. The percentages of
frozen-thawed spermatozoa with normal acrosomal conditions assessed by the abovementioned staining techniques
were significantly correlated with the conception rates of routine AI, rates of transferable embryos in
superovulation/AI-embryo collection tests and in vitro fertilization rates. These results are
consistent with new suggestions that the distribution of acrosomal tyrosine-phosphorylated proteins as well as
the acrosomal morphology of frozen-thawed spermatozoa are AI fertility-associated markers that are valid for
the prediction of AI results and that low conception rates in AI using frozen-thawed spermatozoa with poor
acrosomal conditions result from reproductive dysfunctions in the processes between sperm insemination into
females and early embryo development, probably failed fertilization of frozen-thawed spermatozoa with
oocytes. 相似文献

<Emphasis Type="Italic">Turnip yellow mosaic virus</Emphasis> isolated from Chinese cabbage in Japan
Namiko Kirino Koji Inoue Koji Tanina Yuya Yamazaki Satoshi T. Ohki 《Journal of General Plant Pathology》2008,74(4):331-334
A virus that caused a distinct yellow mosaic was isolated in Okayama, Japan from Chinese cabbage (Brassica rapa L., Pekinensis group). The virus, with spherical particles ca. 28 nm in diameter, was mechanically transmissible only to
cruciferous species. From the host range, characteristic morphology of virus particles, serology and sequence analysis of
coat protein gene, the causal virus was identified as Turnip yellow mosaic virus (TYMV). Seed transmission of TYMV at 0–2.2% in Chinese cabbage was confirmed. This report is the first of TYMV from Chinese
cabbage and in Japan.
The nucleotide sequence data reported are available in the DDBJ/EMBL/GenBank databases as accessions AB358971 and AB358972. 相似文献

Genetic parameters for carcass grading traits, image analysis traits, and monounsaturated fatty acid (MUFA) percentages were estimated in 29,942 Japanese Black cattle from Hyogo Prefecture. The analyzed traits included five carcass grading traits, two image analysis traits, fat area ratio and fineness index, and two MUFA traits, one measured in intermuscular fat using near-infrared spectroscopy (NIRS) and the other in intramuscular fat using gas chromatography (GC). The heritability estimates of image analysis traits and MUFA were moderate to high, ranging from 0.395 to 0.740, and it was considered that they could be improved simultaneously with carcass grading traits because no severe genetic antagonism was observed. Although the heritability of the NIRS-based intermuscular MUFA was slightly lower than that of the GC-based intramuscular MUFA, the genetic correlation between the two methods was as high as 0.804. These results indicate that the NIRS method can be used as an alternative evaluation procedure to predict MUFA in intramuscular fat in the longissimus muscle. 相似文献
