Abstract

 Objectives: Cholera is an endemic disease in Iran and some cases of this disease are reported throughout the world annually. The aim of this study was to determine epidemiology and antimicrobial resistance patterns of Vibrio cholerae O1 biotype ELTor serotype Inaba in 2005 summer outbreak in Iran.

 Methods: Stool samples were collected from patients suspected of having cholera who were admitted to hospitals and clinics and then were cultured in TCBS. Specimens examined by confirmed bacteriological methods and ultimately they were serotyped by special antiserums. Finally 5% of the isolates were sent to Cholera Reference Laboratory for confirmation, serotyping and susceptibility testing. Antimicrobial susceptibility testing was performed by disk diffusion methods and E-test minimal inhibitory concentration (MIC) as recommended by NCCLS.

 Results: Totally, 1118 patients were to have cholera the epidemicity. The Disease was reported from twenty six provinces. The majority of cases were reported from Tehran, Qum and Hamedan with 219, 190 and 150 cases respectively. 50% of patients were between 15-34 years old. 53% of patients were male and 47% female. 97.7% of patients had Iranian nationality, 2.3% were from Afghanistan and Pakistan. 20% of patients were hospitalized and 80% were treated as outpatients. Case mortality rate was 1%. 1104 isolates were Inaba serotype and only 14 cases were ogawa serotype. Our studies revealed that the origin of Vibrio cholerae was consumption of raw vegetables that were watered by sewage. We also isolated V. cholerae from sewages. All isolates were resistant to Co-trimoxazole, Nalidixic acid, Furazolidone, and intermediate to Chloramphenicole. All isolates were susceptible to Tetracycline, Ciprofloxacin, and Erythromycin. MIC for Co-trimoxazole and Nalidixic acid were over 256µg/ml and 1.5µg/ml for Erythromycin. The antibiogram results showed that all isolates had the same origin.

 Conclusion: Our study reveals that, unlike previous epidemics, the causative agent of cholera in summer outbreak of 2005 was V. Cholerae ELTor, serotype Inaba. Concering the similar antibiogram pattern they had the same origin.

Abstract

Background & Objective: Brucellosis is one of the most common zoonotic diseases in Iran and is endemic in all parts of the country. Patients recorded in 1988 were 71,051(132. 4 per 100,000). Brucella species are facultative intracellular bacteria, and therefore a limited number of antibiotics are effective against these organisms. The aim of this study was the
evaluation of in vitro sensitivity of various antimicrobial agents against 47 brucella melitensis strains isolated from blood culture.
Methods: The susceptibility of 47 Brucella melitensis isolates derived from clinical samples were tested in vitro. The minimum inhibitory concentrations (MICs) of the tested antimicrobials were measured by the agar dilution method.MIC90 and MIC50 values were defined as the lowest concentration of the antibiotic at which 90 and 50 percent of the isolates
were inhibited, respectively. The NCCLS criteria for slow growing bacteria were considered to interpret the results.
Results: Tetracycline (MIC50: 0.13μg/ml, MIC90: 0.25 μg/ml) and streptomycin (MIC50:0.003 μg/ml, MIC90:0.25 μg/ml) had the lowest MICs in vitro against the B. melitensis strains. Norfloxacin had the highest (8 μg/ml) MIC90 value. More than half
isolates presented reduced susceptibility to rifampin (MIC value: 2μg/ml).
Conclusion: Brucella isolates remain susceptible in vitro to most antibiotics used for treatment of brucellosis. There is no significantly important resistance problem for antibiotics targeted against Brucella species in Iran. However, since rifampin is commonly used for prevalent diseases such as tuberculosis, the regional susceptibility pattern of rifampin should be assessed periodically.
