| [structure of the salmonella from animals, birds and the environment through the period of 1970-1975]. | studied were biochemically and serologically the species of a total of 8738 salmonella cultures. most of the investigated strains belonged to subgenus i--95 species; to subgenus ii belonged one species (salmonella sofia); to subgenus iii belonged 4 species: salmonella arizonae 11:b:1, 7; salmonella arizonae 35:r:z35; salmonella arizonae 35:z52:1, 5, 7; salmonella arizonae 58:rz53:z57 of three serologic groups. the attention was focused on more than 20 (new to this country) salmonellae among whic ... | 1977 | 595376 |
| epidemiology of salmonella sofia in australia. | in recent years, the incidence of isolation of salmonella sofia in australia has risen from 33% of all poultry isolates in 1982 to a peak of 49% of isolates in 1988. a parallel rise has not been seen in s. sofia isolated from humans. in israel, however, s. sofia has been commonly isolated from both humans and poultry. we investigated the possibility that the israeli strains may belong to a different clonal group and express virulence determinants not seen in the australian isolates, accounting f ... | 1991 | 1674653 |
| the occurrence and growth of microorganisms during the fermentation of fish sausage. | minced fish (mullet) sausage mixes containing added sugar, salt, nitrate, nitrite and spices were fermented (48 h, 30 degrees c) by indigenous flora or by a starter culture (pediococcus acidilactici) and the microbial ecology and behaviour of various bacteria was monitored. pediococcus pentosaceus and lactobacillus plantarum dominated the indigenous fermentation, achieving populations of 10(7)-10(8) cfu/g by 48 h, and decreasing the ph of the mix to 4.5-4.7. significant growth (10(5)-10(7) cfu/g ... | 1991 | 1909546 |

| a non-motile salmonella mutant (6, 7:-:-) and two serological variants encountered in saudi arabia. | a non-motile mutant of salmonella group c1 and two serological variants were isolated during the performance of a national salmonella surveillance program in saudi arabia. most of the biochemical reactions of the strains conformed to those of the genus salmonella except for some atypical reactions. the three strains exhibited different susceptibility patterns to 21 antimicrobial agents. the serological analysis revealed the following antigenic structures: 1, 4, 12, 27:b: - salmonella sofia var. ... | 1984 | 6741347 |
| survival of enterobacteria in liquid cultures during microwave radiation and conventional heating. | bacteria in food have been reported to survive in larger numbers after processing by microwave radiation than after conventional processing. the bactericidal effect of a domestic microwave oven (sharp r-7280) on certain pathogenic enterobacteria species was investigated in vitro, in comparison with conventional heating (boiling). the death rates of different nosocomial strains of escherichia coli, salmonella sofia, salmonella enteritidis, proteus mirabilis and pseudomonas aeruginosa were tested. ... | 1995 | 12099299 |

| a fluorescent amplified fragment length polymorphism study of salmonella enterica serovar sofia, the major salmonella serovar isolated from chickens in australia. | fluorescent amplified fragment length polymorphism (faflp) analysis was performed on 68 isolates of salmonella enterica subsp. salamae serovar sofia (s. sofia). fifty eight isolates were obtained over a period of approximately 15 years from a range of human, chicken industry and environmental sources throughout australia. a further ten isolates were identified from human and poultry sources in israel from 1972 to 1987. analysis of faflp profiles for fragments between 50 to 500 base pairs in leng ... | 2003 | 14695065 |
| a baseline survey of the microbiological quality of chicken portions and carcasses at retail in two australian states (2005 to 2006). | raw poultry products were purchased from the retail market place in two australian states, new south wales (n = 549) and south australia (n = 310). the products sampled on a proportional volume basis were chicken portions with the skin off or skin on, in bulk or tray packs, and whole carcasses. they were collected from butcher shops, supermarkets, and specialty stores from urban areas during the winter (2005) and summer (2006) months. the samples were analyzed to determine the prevalence and con ... | 2008 | 18592737 |
| salmonella sofia differs from other poultry-associated salmonella serovars with respect to cell surface hydrophobicity. | salmonella enterica is one of the most important foodborne pathogens. salmonella enterica subsp. ii 4,12:b:- (salmonella sofia) is commonly found in australian poultry. it has been suggested that physicochemical properties such as surface charge and hydrophobicity may affect bacterial attachment to surfaces and their ability to persist in food systems. a possible link between hydrophobicity cell surface charge and persistence of salmonella from the poultry system was examined. hydrophobicity of ... | 2008 | 19244894 |
| attachment of different salmonella serovars to materials commonly used in a poultry processing plant. | salmonella can adhere to poultry and food contact surfaces and persist to cause diseases. adhesion of salmonella sofia (n = 14), s. typhimurium (n = 6), s. infantis (n = 3) and s. virchow (n = 2) to teflon, stainless steel, glass, rubber and polyurethane were assayed using epifluorescence microscopy. surface free energies of bacteria and materials were calculated using contact angle values and interfacial free energy between isolates and materials determined. surface roughness of the materials w ... | 2009 | 19835771 |
