Background: Antimicrobial resistance is a serious problem worldwide and differs from region to region. This study was planned to determine the incidence and sensitivity pattern of Klebsiella pneumoniae (K. pneumoniae), Escherichia coli (E. coli) and Pseudomonas aeruginosa (P. aeruginosa) in our region and discuss the general issues related to antimicrobial resistance.Methods: Prospective study was carried out between March to October 2015. Samples of urine, blood, pus, CSF and miscellaneous samples (fluids, swabs, sputum and stool) were collected from indoor and outdoor patients for isolation and antimicrobial susceptibility of K. pneumoniae, E. coli and P. aeruginosa in the Department of Microbiology G.R. Medical College, Gwalior (MP).Results: Out of the 5000 samples analyzed 1684 showed growth. K. pneumoniae (38.50%), E. coli (33.29%) and P. aeruginosa (28.19%) constituited a total of 805 isolates. Both E.coli and K. pneumoniae showed highest sensitivity for doxycycline (75%; 67% resp.) and second highest for levofloxacin (70%; 64% resp.), whereas, P. aeruginosa showed highest 57% sensitivity for amikacin followed by 48% for levofloxacin. β-lactam antibiotics and aminoglycosides showed high mean resistance (K.pneumoniae-83%, E.coli-79%, P. aeruginosa-86.4%) and (K. pneumoniae-75%, E. coli-61%, P. aeruginosa-70%) resp.Conclusions: The data indicates high resistance among the gram-negative bacteria for β-lactam and aminoglycoside antibiotics. Increasing resistance to doxycycline and flouroquinolones for K. pneumoniae and E. coli and multidrug resistance to P. aeruginosa is a cause of concern in this region. Thus, there is a need to stop misuse of antibiotics with immediate effect and to implement a strong antimicrobial stewardship program.

Мета роботи — вивчити резистентність до антибіотиків бактеріальних збудників інфекцій сечових шляхів (ІСШ), виділених у пацієнтів урологічного стаціонару в м. Києві. Матеріали і методи. Досліджено 1612 штамів бактерій, виділених із сечі хворих з ІСШ (цистит, уретрит, пієлонефрит), госпіталізованих в урологічне відділення ДУ «Інститут урології НАМН України» у м. Києві протягом 2016 р. Серед пацієнтів переважали жінки — 1201 (74,5 %). Вік хворих становив від 17 до 74 років. Для збору даних використано медичну документацію лікарні. Мікробіологічні дослідження виконано у лабораторії мікробіології ДУ «Інститут урології НАМН України». Аналізували результати культурального дослідження зразків сечі, зібраних за наявності клінічних ознак ІСШ. Дослідження клінічного матеріалу та інтерпретацію отриманих результатів проводили загальноприйнятими методами. Вивчено чутливість уропатогенів до 31 антибіотика дискодифузійним методом відповідно до рекомендацій Інституту клінічних та лабораторних стандартів США (Clinical and Laboratory Standards Institute (CLSI)). Результати та обговорення. Аналіз мікробного спектра сечі виявив домінування серед уропатогенів штамів Escherichia coli (32,0 %), Enterococcus faecalis (19,5 %), Klebsiella pneumoniae (10,9 %), Staphylococcus epidermidis (8,9 %), S. haemolyticus (6,5 %) та Pseudomonas aeruginosa (6,4 %). Частка Enterococcus faecium, Enterobacter aerogenes і Streptococcus viridans становила відповідно 2,5, 2,2 і 1,6 %, Enterobacter cloacae, Klebsiella oxytoca, Acinetobacter baumannii, Proteus vulgaris та Providencia rettgeri — менше 1,0 %. У більшості випадків (69,7 %) мікроорганізми виділено у монокультурі, у решті випадків — у мікробних асоціа- ціях. Високу резистентність до тестованих антибіотиків виявили штами E. aerogenes (45,1 %), E. cloacae (45,7 %), E. faecium (40,9 %), E. faecalis (40,7 %), E. coli (39,9 %), P. aeruginosa (34,0 %), K. pneumoniae (28,6 %). Найбільш активними до уропатогенів були іміпенем (E. coli — 87,6 %, P. aeruginosa — 75,7 %, E. cloacae — 67,3 %, E. aerogenes — 72,6 %, K. pneumoniae — 93,2 %), меропенем (E. coli — 89,1 %, P. aeruginosa — 76,7 %, K. pneumoniae — 82,6 %), лефлоцин (E. coli — 74,5 %, ентерококи — 78,7 %, P. aeruginosa — 76,7 %, E. cloacae — 73,9 %, E. aerogenes — 80,4 %, K. pneumoniae — 83,5 %), амоксицилін/клавуланат (ентерококи — 84,6 %), фурагін (ентерококи — 82,6 %), цефоперазон (K. pneumoniae — 89,2 %, P. aeruginosa — 73,8 %), цефтріаксон (K. pneumoniae — 80,1 %). Висновки. Антибіотикорезистентність збудників ІСШ — важлива терапевтична проблема. Найбільшою активністю до уропатогенів характеризуються іміпенем, меропенем, лефлоцин, амоксицилін/ клавуланат, фурагін, цефоперазон, цефтріаксон, які можна розглядати як препарат вибору для призначення стартової терапії ІСШ. Необхідно здійснювати постійний моніторинг за резистентністю до дії антибіотиків. Політику використання антибіотиків у кожному стаціонарі слід визначати залежно від локальних даних щодо резистентності до протимікробних препаратів.

Abstract Background Although Escherichia coli is the most frequently isolated microorganism in acute biliary tract infections with bacteremia, data regarding its virulence are limited. Results Information on cases of bacteremia in acute biliary tract infection in a retrospective study was collected from 2013 to 2015 at a tertiary care hospital in Japan. Factors related to the severity of infection were investigated, including patient background, phylogenetic typing, and virulence factors of E. coli, such as adhesion, invasion, toxins, and iron acquisition. In total, 72 E. coli strains were identified in 71 cases, most of which primarily belonged to the B2 phylogroup (68.1%). The presence of the iutA gene (77.3% in the non-severe group, 46.4% in the severe group, P = 0.011) and the ibeA gene (9.1% in the non-severe group, and 35.7% in the severe group, P = 0.012) was significantly associated with the severity of infection. Among the patient characteristics, diabetes mellitus with organ involvement and alkaline phosphatase were different in the severe and non-severe groups. Conclusions We showed that bacteremic E. coli strains from acute biliary tract infections belonged to the virulent (B2) phylogroup. The prevalence of the iutA and ibeA genes between the two groups of bacteremia severity was significantly different.

Anualmente o tráfico de animais silvestres retira milhões de aves da natureza. Os cardeais (Paroaria coronata) e cardeais-do-nordeste (Paroaria dominicana) estão incluídos entre as espécies de aves mais traficadas. A microbiota cloacal de passeriformes de vida livre é composta principalmente por bacilos e cocos gram-positivos, já os bacilos gram-negativos predominam em aves de cativeiro. Em situações de estresse e baixa de imunidade as bactérias gram-negativas podem causar infecções oportunistas. O presente trabalho identificou bactérias da microbiota da cloaca de 49 espécimes de P. coronata e P. dominicana apreendidas do tráfico de animais silvestres em São Paulo (SP). Foram isoladas treze espécies de bactérias gram-negativas, incluindo Salmonella spp. e Pseudomonas aeruginosa. A maior frequência de ocorrência foi de Escherichia coli, identificada em 42/49 (85,7%) das amostras fecais. Dentre os isolados de E. coli, 21/42 pertenciam aos grupos filogenéticos B2 e D, relacionados a estirpes patogênicas que causam doença extraintestinal em humanos. Klebsiella pneumoniae foi isolada em 28/49 (57,1%) das amostras. Esses resultados reforçam que as condições estressantes a que esses animais são submetidos em situações de tráfico, incluindo o contato com humanos, podem favorecer a colonização da microbiota cloacal das aves por patógenos, o que representa um risco para a sua reintrodução na natureza considerando-se o possível contato com humanos e outros animais.

O conhecimento da microbiota que compõe as diferentes áreas do organismo tem importância reconhecida para a compreensão de doenças infecciosas que podem acometer os avestruzes, embora se disponha de dados limitados acerca deste assunto na literatura. Foi objetivo deste estudo determinar as espécies de microrganismos (bactérias aeróbias e fungos) que compõem a microbiota normal de avestruzes. Para tanto, foram coletadas amostras de cloaca (N=50) e orofaringe (N=50) de avestruzes hígidos de um criadouro. Das amostras de cloaca, foram isolados Escherichia coli (76% das amostras positivas), Bacillus spp. (60%), Streptococcus spp. (18%), Staphylococcus coagulase-negativo (16%), Pseudomonas aeruginosa (8%), Rhodotorula spp. (8%), dentre outros microrganismos isolados em cultura pura ou em associação com outras bactérias e/ou fungos. Das amostras de orofaringe, foram isolados E. coli (74% das amostras positivas), Candida albicans (44%), Bacillus spp. (38%), Staphylococcus coagulase-negativo (32%), Klebsiella pneumoniae (32%), Rhodotorula spp. (8%), Criptococcus spp. (4%), dentre outros microrganismos isolados em cultura pura ou em associação com outras bactérias e/ou fungos. Verificou-se predominância de bactérias Gram negativas em relação às Gram positivas, nas microbiotas da cloaca e orofaringe. Verificou-se freqüência de ocorrência semelhante entre bactérias Gram negativas nas microbiotas da cloaca e orofaringe, bem como de bactérias Gram positivas nestes mesmos sítios. Observou-se maior ocorrência de leveduras em amostras de orofaringe quando comparadas com as de cloaca.

Sensitivity Pattern

The rapid emergence of antimicrobial resistance in major uropathogens has created a global threat especially in the developing countries. In Bangladesh, prescribers of different regions generally diagnose microbial infection on clinical judgment and select antimicrobial on empirical basis, which unfavorably affects the sensitivity pattern of microbes. The present study was designed to determine the prevalence of antimicrobial resistance of Escherichia coli and Klebsiella species isolated from patients with UTI in a tertiary care hospital. This was a cross sectional study conducted at Sylhet MAG Osmani Medical College Hospital, Sylhet from 1st January to 31st December 2016. A total of 200 clinically suspected urinary tract infection patients aged 16-85 years were included in this study. The isolated Escherichia coli and Klebsiella species were tested for antimicrobial susceptibility according to the guideline of Clinical and Laboratory Standards Institute (CLSI) 2011 using the modified Kirby- Bauer disc diffusion technique. Out of 107 pus cell positive ( 05/HPF) urine samples, 75 (70.1%) yielded significant bacteriuria of which 49 (65.3%) were Escherichia coli and 9 (12%) were Klebsiella species. The isolated Escherichia coli showed absolutely high resistance to ampicillin and cefuroxime (100%), moderately high resistance to ceftazidime (81.6%), ciprofloxacin (77.6%), cotrimoxazole (75.5%), cefotaxime (67.4%) and ceftriaxone (59.2%), moderate rate of resistance to amikacin 48.9% and imipenem 46.9% and least rate of resistance to gentamicin (22.5%), nitrofurantion (22.5%) and netilmicin (6.1%). In addition, Klebsiella species revealed completely resistance to ampicillin, cotrimoxazole, cefuroxime, cefotaxime, ceftriaxone, ceftazidime (100%), moderately high resistance to imipenem (88.9%), nitrofurantoin (77.8%), moderate resistance to ciprofloxacin (44.4%), amikacin (33.3%) and gentamicin (33.3%) and least resistance to netilmicin (11.1%). Hence very high resistance rates of 1st line drugs found in uropathigenic Escherichia coli & Klebsiella species, it is necessary to diagnose clinically followed by culture and sensitivity testing. Regular antibiotic surveillance of a particular geographical area is required to establish reliable information regarding susceptibility pattern of uropathogens in order to preserve the continued usefulness of most antimicrobial agents.Medicine Today 2018 Vol.30(2): 61-66
