Preparation and Evaluation of Rifampicin and Co-trimoxazole-loaded Nanocarrier against Brucella melitensis Infection

Hydrophobic gentamicin-loaded nanoparticles are effective against Brucella melitensis infection in mice.

The clinical management of human brucellosis is still challenging and demands in vitro active antibiotics capable of targeting the pathogen-harboring intracellular compartments. A sustained release of the antibiotic at the site of infection would make it possible to reduce the number of required doses and thus the treatment-associated toxicity. In this study, a hydrophobically modified gentamic...

Brucella melitensis prosthetic joint infection

Periprosthetic joint infection (PJI) due to Brucella spp. is rare. We report a case in a 75-year-old man and review 29 additional cases identified in a literature search. The diagnosis of Brucella PJI is challenging, in particular in non-endemic countries. Serological tests prior to joint aspiration or surgical intervention are reasonable. Involvement of infection control and timely information...

Comparison of living vaccines in producing immunity against natural brucella melitensis infection in sheep and goats in Iran

Immunization against brucella infection. II. Effectiveness of a streptomycin-dependent strain of brucella melitensis.

In previous reports (Elberg and Herzberg, 1953; Herzberg and Elberg, 1953) the isolation and characteristics of a streptomycin-dependent mutant of Brucella melitenis were described.2 The streptomycin-dependent strain retained the biochemical and antigenic characteristics of the virulent parent strain but differed in a requirement for streptomycin for its growth. Growth in vivo was not influence...

Comparison of the efficacy of Brucella abortus strain RB51 and Brucella melitensis Rev. 1 live vaccines against experimental infection with Brucella melitensis in pregnant ewes.

To test the efficacy of rough Brucella strain vaccines in sheep, a vaccine recently developed in cattle (Brucella abortus strain RB51) was assessed in comparison with the conventional Rev. 1 vaccine. Forty-five ewes from twelve to fourteen months of age, from brucellosis-free flocks, were allotted to three groups of fifteen ewes each. Group one was vaccinated by the conjunctival route with 1.73...

Oral immunization of mice with Omp31-loaded N-trimethyl chitosan nanoparticles induces high protection against Brucella melitensis infection

Brucellosis is a group of closely associated zoonotic bacterial illnesses caused by members of the genus Brucella. B. melitensis Omp31 is a promising candidate for a subunit vaccine against brucellosis. This study surveyed the immunogenicity of Omp31 alone and with incomplete Freund's adjuvant (Omp31-IFA) and N-trimethyl chitosan (TMC/Omp31) nanoparticles (NPs), as well as the effect of Omp31 i...
