| chromosomal genotypes (evolutionary lines) of salmonella berta. | the copy number and location of the insertion sequence is200, a mobile dna element, was established across a collection of salmonella berta. all strains contained one common site, assumed to be present in the evolutionary ancestor of this serovar. with one exception, all strains, including recent outbreak isolates from the uk and sporadic isolates of world-wide distribution, were representatives of a single genotypic clone which carried three common is200 insertion sites. this clone has acquired ... | 1992 | 1326468 |
| plasmid profiles as an epidemiological marker in salmonella enterica serovar berta infections. comparison of isolates obtained from humans and poultry. | plasmid profiles of 674 salmonella berta strains isolated in the period 1985-1989 from 674 cases of human infections were recorded. five hundred and eighty-nine of the strains examined (87.4%) contained plasmids and the mean number of plasmids was 1.8 per strain. sixteen different plasmid sizes were recognized, 13 of which had also been reported from s. berta of poultry origin. the plasmids formed 90 different profiles. forty-five of these profiles, comprising 90.7% of isolates, had previously b ... | 1992 | 1562315 |
| plasmid profiles demonstrate that an upsurge in salmonella berta in humans in england and wales is associated with imported poultry meat. | sixteen plasmid profile types have been identified in drug-sensitive isolates of salmonella berta isolated from humans and human food in england and wales in the ten-year period 1981-1990. since 1988 six profile types of epidemiological importance have caused infections in widely-separated geographical areas and of these, four types have been identified in s. berta isolated from chicken carcasses imported from denmark. the findings suggest that imported danish poultry has substantially contribut ... | 1992 | 1572428 |
| stability of plasmids in five strains of salmonella maintained in stab culture at different temperatures. | four strains of salmonella berta and one of salm. enteritidis were stored as stab cultures in sugar-free agar at 5 degrees, 22 degrees and 30 degrees c and in 15% glycerol at -80 degrees c. the stability of the plasmid profiles in each of the strains was monitored over a period of 2.5 years. plasmid profiles were stable in all strains stored at -80 degrees c, and only six of 450 colonies examined from strains kept in sugar-free agar at 5 degrees c had lost plasmid molecules. seventy of 440 colon ... | 1994 | 7961188 |
| separation of listeria monocytogenes and salmonella berta from a complex food matrix by aqueous polymer two-phase partitioning. | in the present study, the use of aqueous polymer two-phase systems for separation of pathogenic bacteria from a complex food sample was investigated. three different two-phase systems, a polyethylene glycol 3350/dextran t 500, a methoxy polyethylene glycol 5000/dextran t 500 and a polyethylene glycol 3350/hydroxypropyl starch system, were compared at ph 3 and ph 6 for their capacity to separate the pathogenic bacteria listeria monocytogenes and salmonella berta from a cumberland sausage. in all ... | 1998 | 9489033 |
| quantitative comparison of intestinal invasion of zoonotic serotypes of salmonella enterica in poultry. | the aim of the present study was to compare the invasion of selected zoonotic salmonella serotypes of poultry in an in vivo chicken intestinal loop model and also in vitro in epithelial cell cultures. invasion was measured relative to a reference strain, salmonella typhimurium 4/74 invh201::tnphoa. two serotypes demonstrated intracellular log(10) counts that differed significantly from all other serotypes tested: salmonella enteritidis pt4 being 1.5 log(10) colony forming units (cfu) (31-fold) h ... | 2002 | 12425791 |
| salmonella meningitis in an immunocompetent adult. | non-enteric salmonella infections in immunocompetent adults are exceedingly rare in the united states, and meningitis is one of the least common extra-intestinal sites. in addition, it is very unusual for a patient with bacterial meningitis to present with classic meningitis signs and symptoms of > 72 h duration. the objective of this work is to describe a rare case of salmonella meningitis in an immunocompetent adult and, in the context of previously published case reports, describe the frequen ... | 2011 | 18534805 |
| draft genome sequences of salmonella enterica subsp. enterica serovar berta atcc 8392 and a nalidixic acid-resistant isolate of this strain. | italic! salmonella entericasubspecies italic! entericaserovar berta has been isolated in multiple animal species and has been implicated in human disease. here, we report a 4.7-mbp draft genome sequence of italic! s. entericaserovar berta (atcc strain 8392) and a nalidixic acid-resistant isolate derived from this strain. | 2016 | 27103707 |
| first outbreak of food poisoning caused by salmonella enterica subspecies enterica serovar berta in italy. | to provide an epidemiologic interpretation of a suspected outbreak of food poisoning caused by salmonella enterica subspecies enterica serovar berta strains isolated from humans and from the leftovers of the implicated foods (cream, dairy-based desserts and eggs). | 2012 | 22607387 |
| salmonella berta myocarditis: case report and systematic review of non-typhoid salmonella myocarditis. | to study trends in the epidemiology, clinical presentation, microbiology and prognosis of non-typhoid salmonella (nts) myocarditis. | 2015 | 26730299 |
| salmonella berta meningitis in a term neonate. | we report the case of a 37-week male infant born via spontaneous vaginal delivery who developed salmonella berta sepsis and meningitis. the infant was born to a mother with active diarrhea and stool cultures growing s. berta. on day 3, the infant developed poor feeding, lethargy, apnea and bradycardia prompting a sepsis evaluation. blood, stool and cerebrospinal fluid cultures were positive for s. berta. an electroencephalogram performed for posturing revealed neonatal status epilepticus. extens ... | 2014 | 25263727 |
| a community outbreak of salmonella berta associated with a soft cheese product. | in september 1994, a complaint was registered at a public health unit concerning a cheese product. in addition, public health laboratories in ontario reported an increase in the number of isolates of salmonella berta from patients with diarrhoeal illness. a clinical, environmental and laboratory investigation was initiated to determine the nature of this outbreak. isolates of salmonella berta were compared using large fragment genomic fingerprinting by pulsed-field gel electrophoresis (pfge). by ... | 1998 | 9528815 |
