Angka kematian infeksi aliran darah cukup tinggi, berkisar 20–50%. Patogen penyebab dapat dibuktikan dengan pemeriksaan kulturdarah yang dilanjutkan dengan uji kepekaan antibiotika. Metode pemeriksaan dapat dilakukan secara manual atau automatis baiksemiautomatis ataupun automatis penuh. Metode manual relatif tidak memerlukan biaya yang besar dibandingkan metode automatisasi.Penelitian ini merupakan analisis observasional dengan desain potong lintang. Metode identifikasi manual memakai metode API danuji kepekaan antibiotika metode difusi cakram antibiotika Kirby Bauer. Kedua metode ini dibandingkan dengan metode semiautomatisTDR-300B. Metode automatis penuh VITEK 2 digunakan sebagai metode rujukan untuk menilai kinerja metode konvensional dansemiautomatis. Bakteri penyebab infeksi aliran darah didominasi Gram negatif kebanyakan Eschericia coli dan Klebsiella pneumonia.Ketepatan metode identifikasi API terhadap VITEK 2 sebesar 87,87%, ketepatan identifikasi metode TDR-300B terhadap metode VITEK2 adalah 90,9%. Hasil ketepatan uji kepekaan antibiotika metode konvensional difusi cakram antibiotika Kirby Bauer terhadap metodeVITEK 2 adalah 84,64%. Ketepatan uji kepekaan antibiotika metode TDR-300B terhadap metode VITEK 2 sebesar 82,5%. Ketepatanmetode API terhadap metode TDR-300B sebesar 84,84%. Ketepatan uji kepekaan antibiotika metode konvensional terhadap metodeTDR-300B sebesar 78,21%. Hasil metode identifikasi dan uji kepekaan antibiotika konvensional tidak berbeda bermakna secara statistikdengan metode semiautomatis TDR-300B. Metode identifikasi dan uji kepekaan antibiotika konvensional masih dapat dipercaya terutamauntuk daerah dengan keterbatasan biaya atau pemeriksaan masih sedikit.

ABSTRACT: This study aimed to isolate Escherichia coli and Salmonella enterica from captured feral pigeons in Fortaleza, Brazil, and, in addition to evaluate the antimicrobial susceptibility profiles and diagnose diarrheagenic E. coli strains. Pigeons were captured in four public locations in Fortaleza with three techniques. Individual cloacal swab samples were collected and submitted to bacterial isolation, biochemical identification and antimicrobial susceptibility test. Disk diffusion technique was used with twelve antibiotics. E. coli strains were submitted to DNA extraction followed by PCR to diagnose five diarrheagenic pathotypes. A total of 124 birds were captured. One bird was positive for Salmonella enterica (0.81%) and 121 (97.58%) were positive for E. coli. Among these, 110 isolates were submitted to antimicrobial susceptibility test and 28.18% (31/110) presented resistance to at least one antibiotic. Resistance to azithromycin was the most frequent (21.82%), followed by tetracycline (10.91%) and sulfamethoxazole with trimethoprim (8.9%). Multidrug resistance, calculated as a resistance to at least 3 antimicrobial classes, was identified in 3.64% (4/110) of strains. The maximum number of antimicrobial classes to which one strain was resistant was seven. Results demonstrated nine different resistance profiles and the most frequent was tetracycline and sulfamethoxazole with trimethoprim (4 strains), followed by chloramphenicol, azithromycin, tetracycline and sulfamethoxazole with trimethoprim (3 strains). Amoxicillin with clavulanic acid and tobramycin presented lowest levels of antimicrobial resistance, to which none of the tested strains were resistant. A single strain was positive for the eltB gene, which is a diagnostic tool to identify the Enterotoxigenic E. coli (ETEC) pathotype. None of the other investigated genes (stx1, stx2, estA, eaeA, ipaH, aatA and aaiC) were identified. The single isolate of S. enterica was a rough strain of Salmonella enterica subsp. enterica, but serotype identification was not possible. However, this isolate presented resistance to amoxicillin, amoxicillin with clavulanic acid, tetracycline and sulfamethoxazole with trimethoprim. Therefore, captured feral pigeons of Fortaleza presented a low prevalence of S. enterica and diarrheagenic E. coli. Considering the investigated pathogens, our results suggest a good health status and a low public health risk. However, important antimicrobial resistance profiles were identified.

Test Result

Chryseobacterium indologenes (C. indologenes) is nonmotile, oxidase-, and indole-positive gram-negative aerobic bacillus. Immunosuppression, comorbidities, use of broad-spectrum antibiotics are known risk factors for C. indologenes-related infections. We report a neutropenic fever caused by C. indologenes in a 16-month-old boy who was treated due to the neuroblastoma. According to the antimicrobial susceptibility test result, he was treated with cephaperazone/sulbactam.
