In this study, we aimed to evaluate the distribution features and antimicrobial susceptibility test results of the microorganisms isolated from the wounds of pediatric and adult patients with burn. The culture and susceptibility test results of the microorganisms, isolated from the wound swabs of the patients hospitalized in a tertiary-burn care center in 10-year period, were retrospectively screened on the microbiology department databases. Their distribution of isolated microorganisms regarding species and susceptibility test results were compared with previous studies. A total of 367 microorganisms, isolated from the burn wounds of 293 patients (13 +/- 18.9 years, F/M: 0.93) (73 adults and 220 pediatric patients), were included in this study. A solitary agent was isolated in 239 (81.6%) patients, while 2 were isolated in 43 (14.7%) and 3 or more agents in 11 (3.8%). From these, 33% of the isolated microorganisms were gram-positive cocci, 61% were gram-negative bacteria, and 6% were Candida spp. The most common isolated microorganisms were Staphylococcus aureus (18.5%), Pseudomonas spp. (16.9%), and Escherichia coli (11.2%), while the least common was Streptococcus spp. (2.5%). Methicillin resistance was 15% among the S. aureus strains. No resistance was observed against levofloxacin, vancomycin, teicoplanin, linezolid, daptomycin, fusidic acid, and tigecycline in S. aureus strains. The highest resistance rates were observed against levofloxacin (64%), tobramycin (64%), pip/tazobactam (63%), imipenem (63%), and the lowest against colistin (5%) and ceftazidime (29%), among Pseudomonas spp. The most common causative agents in burn wound infections and their current antimicrobial susceptibility features should be well identified, in order for prevention of serious complications and optimal management the condition to occur.
Ticks and Fleas Infestation on East Hedgehogs (Erinaceus Concolor) in Van Province, Eastern Region of Turkey

Background: Ixodid ticks (Acari: Ixodidae) and fleas (Siphonaptera) are the major vectors of pathogens threatening animals and human healths. The aim of our study was to detect the infestation rates of East Hedgehogs (Erinaceus concolor) with ticks and fleas in Van Province, eastern region of Turkey. Methods: We examined fleas and ticks infestation patterns in 21 hedgehogs, collected from three suburbs with the greater of number gardens. In order to estimate flea and tick infestation of hedgehogs, we immobilized the ectoparasites by treatment the body with a insecticide trichlorphon (Neguvon (R)-Bayer). Results: On the hedgehogs, 60 ixodid ticks and 125 fleas were detected. All of the ixodid ticks were Rhipicephalus turanicus and all of the fleas were Archaeopsylla erinacei. Infestation rate for ticks and fleas was detected 66.66 % and 100 %, respectively. Conclusion: We detected ticks (R. turanicus) and fleas (A. erinacei) in hedgehogs at fairly high rates. Since many ticks and fleas species may harbor on hedgehogs and transmit some tick-borne and flea-borne patogens, this results are the important in terms of veterinary and public health.
