A wide range of mathematical models of recognition and confusion in psychological experiments is examined. A taxonomy for the classification of these models is proposed. thk taxonomy ‘includes discriminant models, feature-confusion models, sophisticated guessing models and choice models. Both the within-class and between-class relationships of these models are examined so as to provide a framew...

Background: Antimicrobial resistance genes are an acquired phenomenon in nosocomial pathogens as results to uncontrolled and randomly used of antibiotics. Methods: A total 308 samples were collected from different places surfaces for bacterial contamination three main hospitals Wasit province. Bacteria isolated identified using biochemical test, then PCR was order analysis he 16S rRNA gene isol...

Abstract Staphylococcal enterotoxins (SE) are essential in human and animal infection food poisoning. This study analyzed ten genes ( sek, sel, sem, sen, seo, sep, seq, ser, ses , set ) encoding new staphylococcal enterotoxin isolated from animals humans by multiplex polymerase chain reaction (PCR). In Yogyakarta, Indonesia, samples cases (174 isolates), cattle (5 goats isolates) resulted a tot...

Infesting Fusarium species isolated from banana fruit samples were identified and quantified by morphological, mycotoxicological and molecular tools. A total of 19 Fusarium isolates were obtained: F. semitectum was most predominant (26%), followed by F. proliferatum (16%), F. circinatum (16%), F. chlamydosporum (10.5%), F. solani (10.5%), F. oxysporum (10.5%) and F. thapsinum (5%). Fumonisin B1...

Using PCR, we screened 105 isolates of poultry-associated Campylobacter jejuni for the presence of class 1 integrons. Of those isolates, 21% (22 of 105) possessed the integrase gene, but only 5 isolates produced an amplicon in a 5'-3' conserved sequence PCR directed toward amplification of the resistance cassettes. DNA sequencing demonstrated that all five isolates possessed the aminoglycoside ...

Difficulties in accurately identifying serovar 4,[5],12:i:- as monophasic variants of Salmonella enterica serovar Typhimurium mean there is confusion in the reporting of serovars Typhimurium and 4,[5],12:i:-. To gain insight into the prevalence and diversity of these monophasic variants in England and Wales, screening for fljB, hin and the serovar 4,[5],12:i:- DT193-associated genomic island wa...

We investigated the presence of carbapenemases in carbapenem-resistant Pseudomonas aeruginosa isolates, which were collected over a 14-month period Turkish hospital, with in-depth molecular characterization carbapenemase-producing isolates. Among 45 study 2 isolates identified as carbapenemase producers by both Carba NP and Carbapenem Inactivation Method tests, only 1 them gave positive result ...

Duplex PCR was developed to screen Salmonella enterica serovar Typhimurium phage type DT104 and related strains in Thailand because a phage typing laboratory of serovar Typhimurium is not available. Of 46 isolates of serovar Typhimurium and 32 isolates of S. enterica serovar 1,4,[5],12:i:-, 15 (33%) and 30 (94%) were duplex PCR positive, respectively. All isolates were submitted for phage typin...
