Although laboratory dependence is an acknowledged problem in microbiology, it is seldom intensively studied or discussed. We demonstrate that laboratory dependence is real and quantifiable even in the popular model Escherichia coli. Here laboratory effects alter the equilibrium composition of a simple community composed of two strains of E. coli. Our data rule out changes in the bacterial strai...

Efficient water treatment is required to maintain high quality and control microbial growth in recirculating aquaculture systems (RAS). Here, we examined the effects of two methods, ozonation foam fractionation, separately combined, on microbiology twelve identical experimental RAS with rainbow trout (Oncorhyncus mykiss) during 8 weeks. Microbes suspended growing biofilter biofilms were using f...

We describe three cases of orthopaedic contamination caused by Ralstonia pickettii grown from prosthetic joint and implant material cultures following sonication in the microbiology laboratory. Given the temporal association between the cases, lack of clinical or intra-operative features of infection, growth of the organism in the water bath, and unlikely etiology of Ralstonia as a prosthetic j...

this experiment was conducted to determine the effects of dietary myrtle essential oil on small intestinal morphology and microbiology of broiler chickens. two hundred day-old broiler chickens (ross 308) were allocated to 5 treatments, 4 replications with a completely randomized design. the diets were supplemented with: no myrtle essential oil (control), each of myrtle essential oil at levels o...
