Fish is a very important component of human diet. A total 64 samples Clarias gariepinus were collected from two fish ponds each in Yaba, Ijegun, Ikorodu and Epe Lagos State, Nigeria. The bacterial flora the fishes determined quantitatively qualitatively. mean viable count ranged log10 7.6 cfu/g to 7.9 cfu/g. load on skin intestine generally higher than gills. Salmonella between 7.2 it was highe...

The antimicrobial activity of crude tissue sample of sea star Astropecten indicus collected from Mudasal Odai, southeast coast of India was evaluated with the testing human microbial pathogens viz., Escherichia coli, Klebsiella pneumonia, K. oxytoca, Staphylococcus aureus, Streptococcus sp., Pseudomonas aeruginosa, Salmonella paratyphi and S. typhi using solvent system methanol and ethyl acetat...

Cefoperazone (a third generation cephalosporin) has effective in vitro activity against majority of pathogens. Levofloxacin (a flouroquinolone) is one which prescribed more due to its increased antibacterial activity against Gram-positive, Gram-negative, and atypical bacteria. Microbial resistance to antibiotics is now prevalent and poses a serious clinical threat. An attempt has been made to e...

Characterization of Salmonella enterica Serovar Typhi isolates for their Vi capsular polysaccharide antigen-related genetic sequences is desirable to define the role of isolates lacking such sequences in differential replication at unusual sites, including those coinfected with human immunodeficiency virus (HIV). Infection with Vi-negative strains might produce typhoid fever among those immuniz...

The use of microorganisms for biological purpose has become an effective alternative to control pathogens. Bacteria from marine environment are an underutilized source of novel antibiotics. A total of 100 bacteria were isolated from marine samples (Fish, Water and Crustaceans) of Baluchistan coast and screened for antagonistic interaction. Out of these 15 strains showed antibacterial activity. ...

Five different isolates of Pseudomonas aeruginosa were obtained from surgical specimens and minced meat. The isolates were tested for the production of the blue pigment; pyocyanin. Considerable amounts of blue pigment were produced by P. aeruginosa isolates when grown on the four tested media. Müller-Hinton agar was further used for growth, pigment production and sensitivity tests. Pigment prod...

We described previously (W.M. Shafer, L.E. Martin, and J.K. Spitznagel, Infect. Immun. 45:29-35, 1984) the presence of a 37-kilodalton cationic antimicrobial protein (37K CAP) in extracts of granules prepared from human polymorphonuclear granulocytes (PMN). In this investigation, we prepared 37K CAP from PMN granule extracts by sequential ion-exchange and molecular-sieve chromatography and exam...

Aim: To assess the antibacterial activity of crude ethanolic and water extracts stem Rothmannia whitfieldii on clinically isolated typed pathogenic bacterial strains.
 Study Design: This experiment was performed in duplicates under aseptic condition.
 Place Duration Study: Department Microbiology, University Nigeria, Nsukka, Enugu State, Nigeria between April 2005 to August, 2005.&#x0...

A great number of researches over the last years are allocated to know cancer reasons, prevention and treatment strategies. Bacterial infections are one of the promoting factors in cancer development. The present study was carried out to study effects of heat-killed bacteria on cancer cell lines MCF7 and HT-29. To this purpose, four bacterial strains including Salmonella typhi, Sta...

conclusions these extracts can be used as antibacterial agents in treating infectious diseases. further studies are needed for considering this plant as an antibacterial plant and benefit from its clinical applications for routine use. background tagetes genus contains 56 species and is native in north and south america, but some have become widespread around the world. objectives this study wa...
