Última Contribution of different mechanisms to the resistance to fluoroquinolones in clinical isolates of Salmonella enterica BJID Rushdy,Abeer Ahmed; Mabrouk,Mona Ibrahim; Abu-Sef,Ferialla Abdel-Hamid; Kheiralla,Zeinab Hassan; Abdel -All,Said Mohamed; Saleh,Neveen Mohamed. OBJECTIVES: To study the potential factors include gene mutation, efflux pump and alteration of permeability associated with quinolone-resistance of Salmonella enterica strains isolated from patients with acute gastroenteritis and to evaluate the degree of synergistic activity of efflux pump inhibitors when combined with ciprofloxacin against resistant isolates. METHODS: Antimicrobial resistance patterns of fifty-eight Salmonella isolates were tested. Five isolates were selected to study the mechanism of resistance associated with quinolone group, including mutation in topoisomerase-encoding gene, altered cell permeability, and expression of an active efflux system. In addition, the combination between antibiotics and efflux pump inhibitors to overcome the...

Determining the profile of antigen expression among meningococci is important for epidemiologic surveillance and vaccine development. To this end, two new mouse monoclonal antibodies (MAbs) have been derived against Neisseria meningitidis proteins (class 5). The MAbs were reactive against outer membrane antigens and were bactericidal. Selected anti-class 5 MAbs [(5.1)-3E6-2; (5.3)-3BH4-C7; (5.4)-1BG11-C7; (5.5)-3DH-F5G9 also 5F1F4-T3(5.c)], and the two new monoclonal antibodies C14F10Br2 (5.8) and 7F11B5Br3 (5.9), were then tested against different meningococcal strains, (63 strains of serogroup A, 60 strains of serogroup C (from 1972 to 1974); and 136 strains of serogroup B (from 1992) meningococci). Our results demonstrated that the expression of class 5... Tipo: Info:eu-repo/semantics/article Palavras-chave: Neisseria meningitidis; Monoclonal antibodies; Outer membrane protein; Flow cytometry. Ano: 2001 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1413-86702001000300007 Protein and antigen profiles of Leptospira interrogans serovar Hardjo Ciência Rural Lafetá,Bárbara Nobre; Castro,Elaine Cristina de; Silva,Nivaldo da. The protein profile of the outer membrane of Leptospira interrogans serovar Hardjo subtype hardjoprajitno associated with the bovine natural immune response was investigated. The outer membrane proteins were extracted utilizing Triton X114 and precipitated with acetone. The protein sample was then resolved by SDS-PAGE and reacted in western blot against sera from a hyperimmune rabbit and from naturally infected bovines. In silver stained gels, 14 protein bands were observed, among which four proteins, with 22, 29, 47 and 63kDa, appeared as major constituents. Western blot tests with hyperimmune rabbit antiserum detected bands corresponding to proteins with 35; 27; 24; 21; 17 and 14kDa, while 32kDa and 45kDa proteins were the most immunoreactive with sera...
