Resistance to Antibiotics in Thermophilic Campylobacters.

() is one of the most frequent causes of bacterial enterocolitis globally. The disease in human is usually self-limiting, but when complications arise antibiotic therapy is required at a time when resistance to antibiotics is increasing worldwide. Mechanisms of antibiotic resistance in bacteria are diverse depending on antibiotic type and usage and include: enzymatic destruction or drug inactivation; alteration of the target enzyme; alteration of cell membrane permeability; alteration of ribosome structure and alteration of the metabolic pathway(s).

Prevalence of antimicrobial resistance in Campylobacter spp.: A review of the literature.

Campylobacter spp. are commensal organisms in the intestinal tract of food producing and companion animals. There is an increasing trend of human campylobacteriosis worldwide, including complicated cases that request treatment by antibiotics.

Campylobacter concisus.

Campylobacter concisus has been described as the etiological agent of periodontal disease, inflammatory bowel diseases, and enterocolitis. It is also detected in healthy individuals. There are differences between strains in healthy individuals and affected ones by production of two exototoxins.

Inhibitory effects of propolis and essential oils on oral bacteria.

Introduction: Propolis is a natural composite balsam. In the past decade, propolis has been extensively investigated as an adjuvant for the treatment of periodontitis. This study aimed to investigate antimicrobial activities of propolis solutions and plant essential oils against some oral cariogenic (Streptococcus mutans, Streptococcus mitis, Streptococcus sanguis, Lactobacillus acidophilus) and periodontopathic bacteria (Actinomyces odontolyticus, Eikenella corrodens, Fusobacterium nucleatum).

Antimicrobial susceptibility and β-lactamase production in Bacillus cereus isolates from stool of patients, food and environment samples.

Background/aim: Bacillus cereus (B. cereus) usually ingested by food can cause two types of diseases: vomiting due to the presence of emetic toxin and diarrheal syndrome, due to the presence of diarrheal toxins. Systemic manifestations can also occur.
