Enhancing the thermal destruction of Escherichia coli O157:H7 in ground beef patties using trans-cinnamaldehyde Trans-cinnamaldehyde (TC) is an active antimicrobial substance extracted from the spice cinnamon which offers meat processors a labelfriendly, non-artificial sanitising agent. The effectiveness of TC in the inactivation of the foodborne pathogen Escherichia coli 0157:H7 in undercooked...

The most notable method of infection from Escherichia coli O157 (E. coli O157) is through contaminated food products, usually ground beef. The objective of this study was to evaluate seven cast copper alloys (61 to 95% Cu) for their ability to reduce the viability of E. coli O157, mixed with or without ground beef juice, and to compare these results to those for stainless steel. E. coli O157 (N...

Consumption of food contaminated with Escherichia coli O157:H7 and Salmonella can cause enteric disease in consumers. If not properly sanitized, knives used during animal harvest can spread these and other pathogens. This study evaluated the reduction of E. coli O157:H7 and Salmonella on harvesting knives after nonthermal sanitation. Knives were inoculated in cocktails of E. coli O157:H7 or Sa...

The objectives of this study were to determine and compare the prevalence and antimicrobial resistance of Campylobacter species in swine reared in conventional and antimicrobial-free (ABF) production systems. Campylobacter coli was the predominant species, with 1,459 isolates (99%) in the study. We found significantly higher prevalence of C. coli on the ABF farms (77.3%) than on the conventiona...

Effects of different land uses on densities of Escherichia coli, enterococci, and Clostridium perfringens in the water and soil of a tropical watershed were investigated. Densities of fecal indicator bacteria (FIBs) in the watershed exhibited a clear land-use dependency in the stream water. Significantly higher concentrations were detected in the urban portion of the stream (417, 420, and 44 CF...

BACKGROUND Inflammatory bowel disease (IBD) is a common cause of signs of gastrointestinal disease in cats. A subset of cats with IBD has neutrophilic inflammation of the intestinal mucosa. HYPOTHESIS Neutrophilic enteritis in cats is associated with mucosal invasion by microorganisms, and specifically Campylobacter spp. ANIMALS Seven cats with neutrophilic IBD and 8 cats with lymphoplasmac...

Several thymidine diphosphate sugar compounds have been isolated from Escherichia coli strains and other microorganisms. TDP-X, isolated from E. coli strain Y-10 by Strominger and Scott (1) and from other strains of E. coli (2) and TDP-X2 isolated from E. coli strain B, by Okazaki, Okazaki, and Kuriki (3) are unusual acetamido sugar-containing nucleotides (4). The sugars are 4-acetamido-4,6-did...

OBJECTIVE In this study, the cytopathic effects of Trichomonas vaginalis were investigated in L929 mouse fibroblast cell cultures (FCC) under different conditions: only parasite, or coexistence with Candida albicans and Escherichia coli. METHODS The parasite was isolated from a symptomatic patient and cultured in Cysteine-Peptone-Liver infusion Maltose medium (CPLM). C. albicans strain 10235 ...

Among Escherichia coli strains of the O55:H7 serovar, which is considered the ancestor of Shiga toxin-producing E. coli (STEC) O157:H7, two subtypes, H7a,7b and H7a,7c (briefly, H7a,b and H7a,c, respectively), of the H7 flagellar antigen have been described previously [J. Wright and R. Villanueva, J. Hyg. (Camb.) 51:39-48, 1953; Y. A. Ratiner and V. A. Sinelnikova, Zh. Microbiol. Epidemiol. Imm...

Campylobacter species are one of the leading causes of foodborne disease in the United States. Campylobacter jejuni and Campylobacter coli are the two main species of concern to human health and cause approximately 95% of human infections. Molecular typing methods, such as pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) are often used to source track foodborne bact...
