Comparison of Virulence between Seoul Virus Strain SR‐11 and Hantaan Virus Strain 76–118 of Hantaviruses in Newborn Mice
Microbiology and Immunology - Tập 37 Số 7 - Trang 557-562 - 1993
Yung Choon Yoo, Kumiko Yoshimatsu, Ryu Yoshida, Mizuho Tamura, Ichiro Azuma, Jiro Arikawa
AbstractVirulence of hantavirus strain of SR‐11 Seoul virus and Hantaan 76–118 (HTN) of Hantaan virus were compared. Infections of both strains were lethal in newborn mice. However, inoculum required to cause lethal infection was about 4,000 times higher for strain HTN (1.65 × 103 PFU/mouse/LD50) than for strain SR‐11 (0.36...... hiện toàn bộ
Anti‐inflammatory properties of intestinal Bifidobacterium strains isolated from healthy infants
Microbiology and Immunology - Tập 56 Số 1 - Trang 27-39 - 2012
Ekaterina V. Khokhlova, Smeianov Vv, Б. А. Ефимов, Л. И. Кафарская, С. И. Павлова, Andrey N. Shkoporov
ABSTRACTCertain Bifidobacterium strains have been shown to inhibit inflammatory responses in intestinal epithelial cells. However, the precise mechanisms of these effects, including the chemical nature of the active compounds, remain to be elucidated. Here partial characterization of the anti‐inflammatory properties of Bifido...... hiện toàn bộ
Amplification of all 11 RNA segments of group A rotaviruses based on reverse transcription polymerase chain reaction
Microbiology and Immunology - Tập 56 Số 9 - Trang 630-638 - 2012
Yoshiki Fujii, Takashi Shimoike, Hirotaka Takagi, Kosuke Murakami, Reiko Todaka‐Takai, Youngbin Park, Kazuhiko Katayama
ABSTRACTGroup A rotaviruses (RVA) are a major cause of acute infantile gastroenteritis. The viral genome comprises 11 double‐stranded RNA segments and the respective gene segments are classified into more than eight genotypes, according to the nucleotide sequence similarities. So far, it has been difficult to amplify full‐length sequences of long RNA segments of ro...... hiện toàn bộ
Detection of antibodies against Fusobacterium necrophorum and Porphyromonas levii-like species in dairy cattle with papillomatous digital dermatitis
Microbiology and Immunology - Tập 54 Số 6 - Trang 338-346
Kyaw Kyaw Moe, Takahisa Yano, Kazuhiro Misumi, Chikara Kubota, Kazumi Nibe, Wataru Yamazaki, Michio Muguruma, Naoaki Misawa
Detection and Genetical Characterization of Shiga Toxin‐Producing Escherichia coli from Wild Deer
Microbiology and Immunology - Tập 42 Số 12 - Trang 815-822 - 1998
Hiroshi Asakura, Sou‐ichi Makino, Toshikazu Shirahata, Teizo Tsukamoto, Hisao Kurazono, Tetsuya Ikeda, Kouichi Takeshi
AbstractShiga toxin (Stx)‐producing Escherichia coli (STEC) strains isolated from wild deer in Japan were examined. A total of 43 fecal samples were collected 4 times from 4 different sites around Obihiro City, Hokkaido, Japan, in June and July 1997. Seven STEC strains were isolated by PCR screening, all of them were confirmed by ELISA an...... hiện toàn bộ
Rapid detection and quantification of Ebola Zaire virus by one‐step real‐time quantitative reverse transcription‐polymerase chain reaction
Microbiology and Immunology - Tập 61 Số 3-4 - Trang 130-137 - 2017
Young‐Tae Ro, Anysha Ticer, Ricardo Carrion, Jean L. Patterson
ABSTRACTGiven that Ebola virus causes severe hemorrhagic fever in humans with mortality rates as high as 90%, rapid and accurate detection of this virus is essential both for controlling infection and preventing further transmission. Here, a one‐step qRT‐PCR assay for rapid and quantitative detection of an Ebola Zaire strain using ... hiện toàn bộ
Maternal Transmission and Dental Caries Induction in Sprague‐Dawley Rats Infected with Streptococcus mutans
Microbiology and Immunology - Tập 32 Số 8 - Trang 785-794 - 1988
Takashi Ooshima, Norio Sumi, A Izumitani, S Sobue
AbstractThirty‐four female rats (18 days old) were infected with Streptococcus mutans MT8148R (serotype c) or 6715 (g). Diets containing different proportions of sucrose were used to prepare the dams which harbored various levels of S. mutans in their oral ca...... hiện toàn bộ
An Evaluation of Serodiagnostic Tests in Patients with Candidemia: Beta‐Glucan, Mannan, Candida Antigen by Cand‐Tec and D‐Arabinitol
Microbiology and Immunology - Tập 37 Số 3 - Trang 207-212 - 1993
Shigeru Kohno, Kotaro Mitsutake, Shigefumi Maesaki, Akira Yasuoka, Takashige Miyazaki, Mitsuo Kaku, Hironobu Koga, Kohei Hara
AbstractThe serodiagnostic tests, beta‐glucan, mannan, candida antigen by Cand‐Tec, and D‐arabinitol were evaluated in 10 patients with candidemia, 14 patients with suspected fungemia, and 10 healthy persons. By blood culture or lysis centrifugation, C. albicans was isolated from 5 patients, C. parapsilosis...... hiện toàn bộ
Kinetics of Anti‐Mannan Antibodies Useful in Confirming Invasive Candidiasis in Immunocompromised Patients
Microbiology and Immunology - Tập 40 Số 2 - Trang 125-131 - 1996
A. Johanna M. van Deventer, Wil H. F. Goessens, J H van Zeijl, Jan W. Mouton, M. F. Michel, Henri A. Verbrugh
AbstractIn studying the anti‐mannan antibodies longitudinally in serial serum samples of three immunocompromised patients, it was observed that anti‐mannan antibodies started to increase shortly after the moment that cultures of deep‐tissue sites became positive with Candida albicans. The mean anti‐mannan antibody titers determined in a g...... hiện toàn bộ
The Relationship between Microbiota and Polyamine Concentration in the Human Intestine: A Pilot Study
Microbiology and Immunology - Tập 51 Số 1 - Trang 25-35 - 2007
Mitsuharu Matsumoto, Yoshimi Benno
AbstractThe fecal microbiota of 10 hospitalized elderly subjects and 14 healthy adults were analyzed by terminal‐restriction fragment length polymorphism (T‐RFLP) analysis using HhaI, MspI, HaeIII, and AluI, as well as fecal polyamine (PA) concentration. The ...... hiện toàn bộ
