BACKGROUND Kocuria, previously classified into the genus of Micrococcus, is commonly found on human skin. Two species, K. rosea and K. kristinae, are etiologically associated with catheter-related bacteremia. CASE PRESENTATION We describe the first case of K. kristinae infection associated with acute cholecystitis. The microorganism was isolated from the bile of a 56-year old Chinese man who ...

The laboratory findings and clinical presentations in urinary infections in 23 nurses, 10 caused by Micrococcus subgroup 3 and 13 by Escherichia coli, were studied, and the symptoms and possible predisposing factors compared. There were no important differences between the two groups. The infections caused by Micrococcus subgroup 3 were symptomatically severe, as were those caused by Escherichi...

Micrococcus lysodeikticus (A.T.C.C. 4698), a Gram-positive bacterium, stimulates the production of a high titre of antibodies of restricted heterogeneity, as seen by electrophoresis and sequence analysis (Van Hoegaerden et al., 1975; Van Hoegaerden & Strosberg, 1976). Simultaneous vaccination of rabbits with Micrococcus and another antigen, such as lysozyme methyl ester or tobacco-mosaic virus,...

Bee pollen, which is filled into the cells of honeycomb by honeybees to use in nutrition, enriched with digestive enzymes and organic acids from honey salivary gland secretions honeybees. Lactic acid fermentation takes place comb cell under anaerobic conditions bee bread formed. We have limited knowledge about bacteria yeasts are involved process. Samples collected 8 different beehives same api...

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. ...

The essential oils extracted from the young stems and leaves of Chamaecyparis lawsoniana (A.Murray) Parl. have been analysed by Gas Chromatography and Gas Chromatography coupled to Mass Spectrometry. A total of 66 compounds were identified representing around the 99% of the total oil. The oil was richer in monoterpenes than in sesquiterpenes. The only main component was limonene with a percenta...

OBJECTIVES Study was conducted to assess whether temporal variation exists in airborne microbial concentrations of a hospital ward (west-Chennai, India) using active and passive methods, and characterise the microorganisms. METHODS Air samples (duplicates) were collected simultaneously using exposed-plate, impingement (BioSampler) and filtration (personal sampling filter cassette loaded with ...

Endophytic microorganisms, defined as fungi or bacteria that colonize the interior of plants without causing any immediate negative effects or damages, have reciprocal relationships with host plants. In some cases their presence is beneficial to the host due to the synthesis of bioactive compounds, among which several alcohols, esters, ketones and others that may react with other compounds and ...

Resistance of microorganisms to antibiotics has increased. The use of natural components with antimicrobial properties can be of great significance to reduce this problem. The presented work is focused on the study of the effect of encapsulation of selected plant and animal antimicrobial substances (herbs, spices, lysozyme and nisin) on their activity and stability. Antimicrobial components wer...
