Previously we have shown that the open reading frame 2 protein (ORF2 protein), which is encoded at the 3 ' end of serine protease of Aeromonas sobria (ASP), functions as a chaperone protein in periplasm in the production of ASP. Both proteins, ASP and ORF2 protein, associate in periplasm and ORF2 protein helps ASP to take an active form. ASP which is dissociated from ORF2 protein emerges in milieu...<br/><br/>Rasel Khan, Eizo Takahashi, Thandavarayan Ramamurthy, Yoshifumi Takeda, Keinosuke Okamoto (2007) <i>Microbiol Immunol</i> <i></i> <i></i> 51: 10 963-976<br/>

Aeromonas sobria causes septic shock, a condition associated with high mortality. To study the mechanism of septic shock by A. sobria infection, we examined the vascular leakage (VL) activity of A. sobria serine proteinase (ASP), a serine proteinase secreted by this pathogen. Proteolytically active ASP induced VL mainly in a bradykinin (BK) B(2) receptor-, and partially in a histamine-H(1) recepto...<br/><br/>Takahisa Imamura, Hidemoto Kobayashi, Rasel Khan, Hidetoshi Nitta, Keinosuke Okamoto (2006) <i>J Immunol</i> <i></i> <i></i> 177: 12 8723-8729<br/>

Antibiotic resistance in Helicobacter pylori is a growing public health problem. Many H. pylori isolates carry plasmid DNAs of extremely variable size but so far no drug resistance properties were mediated by H. pylori plasmids. In this study, we investigate the primary antibiotic resistant rates of H. pylori to four different antibiotics. The frequency of plasmids as well as the relation between ...<br/><br/>Rasel Khan, Hidetaka Matsui, Morikazu Onji (2005) <i>Bangladesh J Microbiol</i> 22: 2 87-92<br/>

Resistance of Helicobacter pylori to clarithromycin is mostly associated with point mutations, generally adenine-to-guanine transition at either position 2142 or 2143 or an adenine-to-cytosine transversion at position 2142 in domain V, the macrolide binding pocket, of 23S rRNA gene. Furthermore, many H. pylori isolates carry plasmid DNAs of extremely variable size but so far no drug resistance pro...<br/><br/>Rasel Khan, Hidetaka Matsui, Morikaju Onji (2005) <i>Bangladesh J Microbiol</i> 22: 2 113-116<br/>

Twelve clarithromycin-resistant (MIC, > or = 1 microg/ml) Helicobacter pylori isolates were analyzed for point mutations in the 23S rRNA gene. Sequence analysis of all of the resistant isolates revealed a T-to-C transition mutation at position 2182. Transformation experiments confirmed that a single T-to-C transition mutation at position 2182 is associated with clarithromycin resistance.<br/><br/>Rasel Khan, Shamsun Nahar, Jinath Sultana, Mian Mashhud Ahmad, Motiur Rahman (2004) <i>Antimicrob Agents Chemother</i> <i></i> <i></i> 48: 9 3567-3569<br/>

Antimicrobial susceptibility of 120 Helicobacter pylori isolates to metronidazole, tetracycline, clarithromycin, and amoxicillin was determined, and 77.5, 15, 10, and 6.6% of the isolates, respectively, were resistant. Only rdxA inactivation and both rdxA and frxA inactivation were responsible for metronidazole resistance in 66% (8 of 12) and 33% (4 of 12) of the isolates, respectively.<br/><br/>Shamsun Nahar, Asish K Mukhopadhyay, Rasel Khan, Mian Mashhud Ahmad, Simanti Datta, Santanu Chattopadhyay, Swapan Chandra Dhar, Shafiqul Alam Sarker, Lars Engstrand, Douglas E Berg, G Balakrish Nair, Motiur Rahman (2004) <i>J Clin Microbiol</i> <i></i> <i></i> 42: 10 4856-4858<br/>

PCR surveillance of the rstR genes of CTX phages in Vibrio cholerae O1 and O139 showed no relationship between the incidence of disease and changes in the rstR but showed variations in their presence in O1 and O139 strains and the occurrence of multiple types in a few strains.<br/><br/>Suraia Nusrin, G Yeahia Khan, N A Bhuiyan, M Ansaruzzaman, M A Hossain, Ashrafus Safa, Rasel Khan, Shah M Faruque, David A Sack, T Hamabata, Yoshifumi Takeda, G Balakrish Nair (2004) <i>J Clin Microbiol</i> <i></i> <i></i> 42: 12 5854-5856<br/>

Sixty-nine bacteriologically confirmed Streptococcus pneumonie strains were tested for antimicrobial susceptibility between 1998 and 1999. Of the 15 (21.7%) penicillin-resistant isolates, 2 (13.3%) showed complete resistance (MIC ≥ 2.0 microgram/ml) and 13 (86.7%) showed intermediate resistance (MIC, 0.12 to 1.0 microgram/ml). The overall percentages of all isolates resistant to ampicillin, chlo...<br/><br/>Rasel Khan, Md.

Shigella dysenteriae type 1 is the causative agent of the most severe form of bacillary dysentery, which occurs as epidemics in many developing countries. We isolated a bacteriophage from surface water samples from Bangladesh that specifically lyses strains of S. dysenteriae type 1. This phage, designated SF-9, belongs to the Podoviridae family and has a 41-kb double-stranded DNA genome.

Data on the seroprevalence of antibodies protective against the varicella-zoster virus are needed to develop strategies to prevent varicella infections in Bangladesh. Of 1209 patients evaluated at referral-level health facilities in Dhaka, 943 (78%) had no known history of chickenpox and were tested by latex agglutination for the presence of varicella-zoster antibody in serum.

Bacillary dysentery caused by Shigella species is a public health problem in developing countries including Bangladesh. Although, shigellae-contaminated food and drinks are often the source of the epidemic's spread, the possible presence of the pathogen and transmission of it through environmental waters have not been adequately examined. We analyzed surface waters collected in Dhaka, Bangladesh, ...<br/><br/>Shah M Faruque, Rasel Khan, M Kamruzzaman, Shinji Yamasaki, Q Shafi Ahmad, Tasnim Azim, G Balakrish Nair, Yoshifumi Takeda, David A Sack (2002) <i>Appl Environ Microbiol</i> <i></i> <i></i> 68: 8 3908-3913<br/>
