O objetivo do presente estudo foi avaliar o perfil de resistência de microrganismos isolados em fones de ouvidos de alunos de uma instituição de ensino superior (IES) de Juazeiro do Norte-CE. Foram adquiridas 40 amostras aleatoriamente com os discentes da IES e acondicionadas em tubos contendo solução salina, essas amostras foram levadas para o laboratório de microbiologia do Centro Universitário Dr. Leão Sampaio, onde foram abertos e inoculados em meio Brain Hair Infusion (BHI), onde foram incubados em estufa bacteriológica a 37 ºC. Após 24 horas foi realizado o semeio nos meios de cultura (Agar Manitol Salgado, Agar Sangue e Agar Eosina Azul de Metileno - EMB), posteriormente foram realizadas as provas bioquímicas para confirmação das espécies, por fim realizou-se o antibiograma  utilizando os  discos de Amicacina, Gentamicina, Ofloxacina, Oxacilina, Norfloxacina, Ciprofloxacina e Penicilina G. Foi observado que 100 % das amostras encontravam-se contaminadas por um ou mais tipos de microrganismos (12,5 % de Streptococcus sp, 70 % de Staphylococcus aureus, Staphylococcus coagulase negativa 30%, Citrobacter freundii 7,5 %, Enterobacter aerogenes 2,5 % e Cândida sp. 35 %). A partir do antibiograma foi possível observar resistência das cepas para os antibióticos Penicilina G e Oxacilina. Baseado nos resultados obtidos é necessário que os discentes tenham um cuidado maior com os fones de ouvidos uma vez que, eles mal higienizados podem aglomerar diversos tipos de bactérias resistentes e podem causar infecções no canal auditivo.

A Infecção no Trato Urinário (ITU) acometendo pacientes em Unidades de Terapia Intensiva (UTIs) é uma realidade preocupante, agravada pelo uso irracional de antimicrobianos e a alarmante multirresistência em microrganismos. Nós avaliamos o nível de assertividade quanto ao uso de antimicrobianos durante à antibioticoterapia empírica (ATE), em pacientes diagnosticados com ITU, comparando tal tratamento farmacológico empírico e o realizado após o antibiograma (antibioticoterapia direcionada), além disto, estimamos a prevalência dos agentes etiológicos e analisamos os fatores de risco associados. Este é um estudo observacional e transversal, realizado em 2015, no qual foram avaliados pacientes de ambos os sexos e todas as idades apresentando ITU e submetidos à antibioticoterapia, internados em uma UTI de um hospital no sul de Minas Gerais, Brasil. Dos 49 pacientes avaliados (28 mulheres [M] e 21 homens [H]), a média de idade foi 55±19 anos (IC(95) 49-61) e a faixa etária ≥70 anos foi a predominante. Quatorze diferentes microrganismos foram causadores de ITUs, sendo que 28,3% (IC(95%) 16,2-40,4) dos isolados clínicos tiveram Escherichia coli como o agente etiológico (33,3% H e 28,6% M); 18,9% (IC(95%) 8,3-29,4) Acinetobacter baumannii (33,3% H e 10,7% M); 15,1% (IC(95%) 5,5-24,7) Klebsiella pneumoniae (19% H e 14,3% M); 11,3% Pseudomonas aeruginosa (9,5% H e 14,3% M); 5,7% Enterobacter aerogenes (14,3% H); 3,8% Klebsiella oxytoca; 3,8% Staphylococcus aureus (7,1% M); e 1,9% para cada um dos seguintes microrganismos: Enterococcus faecalis (4,8% H); Proteus mirabilis (3,6% M); Enterobacter cloacae (3,6% M); Providencia rettgeri (4,8% H); Citrobacter koseri (3,6% M); Citrobacter freundii (3,6% M); e Fungos leveduriformes (4,8% H). As prevalências de ITUs causadas por A. baumannii e P. aeruginosa foram influenciadas pelo sexo (χ² com p<0,001). No sexo masculino, houve correlações positivas “substanciais” entre o aumento da idade (em anos) e a prevalência de ITU causada por E. coli (r = 0,69) ou entre idades menos avançadas e a prevalência de ITU causada por A. baumannii (r = -0,7). No sexo feminino, houve uma correlação positiva “extremamente forte” entre o aumento da idade e a prevalência de ITU causada por E. coli (r = 0,94; IC(95) 0,66-0,99; p<0,0014). Os antibióticos mais utilizados de forma empírica (ATE) foram: Ciprofloxacina (14,3% IC(95%) 4,7-24,1), Cefepima (14,3%) e Vancomicina (10%), e após o antibiograma (antibioticoterapia direcionada): Ceftazidima (16,3% IC(95%) 6-26,7), Ciprofloxacina (14,3% IC(95%) 4,5-24,1), Polimixina B (10,2%), Imipenem (10,2%) e Ampicilina + Sulbac. (8,2%). Em 20% dos casos, as terapias empíricas (ATE) foram consideradas “inapropriadas/não acertadas”. Contudo, também devemos ter ciência da necessidade clínica e quanto ao imediatismo para o tratamento de uma ITU em UTI, uma vez que a doença pode ser fatal se uma terapia não for instituída, portanto, nós aconselhamos avaliações mais minuciosas, tanto da racionalidade do uso de antibióticos, quanto dos fatores de risco para o desenvolvimento de ITUs em UTIs.

Cefoxitin resistance in Klebsiella pneumoniae from Escherichia coli strains isolated in Greek hospitals was found to be due to the acquisition of similar plasmids coding for group 1 beta-lactamases. The plasmids were not self-transferable but were mobilized by conjugative plasmids. These elements have also been spread to Enterobacter aerogenes. The most common enzyme was a Citrobacter freundii-derived cephalosporinase (LAT-2) which differed from LAT-1 by three amino acids.

Bed linen is clearly recognized as a potential reservoir for microorganisms and could be a vector of disease transmission. The present study was aimed at isolating and characterizing bacteria and fungi from different kinds of bed linen of student in Ekiti State University hostels. Pour plate method was used for the enumeration of total bacteria count from the posterior and anterior end of the bed linen. The average bacteria count for the anterior and posterior end was 7.46 and 7.16 Log10 CFU/ml respectively. The most dominant microbial species were bacteria and these were mostly found in the environment and on human skin. The bacteria isolated were Staphylococcus aureus, Staphylococcus epidermidis, Proteus mirabilis, Enterobacter aerogenes, Bacillus cereus, Escherichia coli and Klebsiella aerogenes. Bacillus cereus had the highest frequency of occurrence (25%), followed by Staphylococcus aureus (15%), Escherichia coli (15%), Klebsiella aerogenes (15%), Staphylococcus epidermis (15%), Enterobacter aerogenes (10%) and Proteus mirabilis (5%). The fungi isolates were Aspergillus sulphureus, Aspergillus fumigatus, Aspergillus niger, Aspergillus flavus and Fusarium spp. Antibiotics susceptibility test was carried out on the bacteria isolates with gram negative bacteria showing resistance to Cotrimoxazole and gram positive bacteria showing resistance to Amplicillin. Most of the bacteria isolates have multiple antibiotics resistance. The bacterial isolates were susceptible to Ciprofloxacin. Plasmid profiling was also done with Escherichia coli having three high molecular weight plasmids, Bacillus cereus and Enterobacter aerogenes do not possess plasmid. The identified species are suspected to be opportunistic pathogens for human, representing a risk for people with weakened immune system, especially in cases of super-infection.

Silica gel thin-layer chromatography was employed to detect lecithinase activity induced from bacterial resting cell preparations induced from bacterial resting cell preparations incubated at 37 C for 4 h in the presence of purified egg yolk lecithin. Bacillus subtilis, Bacillus cereus, Serratia marcescens, and Pseudomonas aeruginosa hydrolyzed lecithin with the formation of free fatty acids as the sole lipid-soluble product. In none of the Escherichia coli and Citrobacter freundii strains tested could lecithinase activity be detected. Four among eight strains of Enterobacter aerogenes and one among 12 strains of Proteus tested produced negligible amounts of free fatty acid.

The purpose of the work was to investigate the organoleptic, physico-chemical and microbiological indices of traditional Carpathian cheeses, in particular, brynza, butz and vurda, made directly on the mountain valleys with traditional technology in Rakhiv district of the Transcarpathian region. Of 16 samples of cheese, 13 samples were cheese butz (samples 1, 2, 3, 5, 6, 7, 8, 9, 10, 11, 12, 13, 15); vurda cheese (samples 4 and 16) and cheese of brynza a year ago (sample 14). Experimental studies of organoleptic, physico-chemical and microbiological parameters of cheese samples were carried out in the laboratory of the milk and milk products department and in the department of biotechnology at Rzeszow University (Poland). In samples of cheese, organoleptic parameters were studied in accordance with GOST 7616-85; active acidity – by potentiometric method using the pH meter of the ARN-9 brand; titrated acidity – titrarily (in degrees Turner) according to GOST 3624-67. The mass fraction of salt in the cheese was determined by titration of the extract with nitric oxide silver (GOST 3627-81). The detection of bacteria of the genus Staphylococcus aureus was determined by sowing on a solid Gissa with mannitol, with further detection and confirmation of the belonging of the grown colonies to Staphylococcus aureus (GOST 30347-97). The detection of bacteria of the genus Salmonella was determined by sowing on the Endo solid medium (GOST 31659-2012). The bacteria of the intestinal stem group were determined by sowing on a Kessler liquid medium (GOST 9225-84). Cultivation of microorganisms was carried out at temperature +37 °С for 48 h. According to researches of organoleptic parameters of cheeses it was found that samples of cheese butz were characterized by sour milk, and samples of 3 and 5 sour taste and aroma, a dense humus consistency and from gray to white color. Figure – with single small and large bodies of irregular shape. According to studies of organoleptic parameters of cheese, the taste and aroma of the product should be given – light sour milk, salted, which is confirmed by the salt content – 4.6%. Consistency was crumbly, the color was yellow. Samples of cheese vurda were characterized by delicate butter, sour milk taste and smell, paste, crumbly consistency and white color. Analyzing the acidity of butz cheese it was that it was high particularly in samples 3, 8 and 14, which was reflected in organoleptic parameters. In the samples of vurda titrated acidity was 75 °T in sample 4 (pH 5.7) and 16 °T in sample 16 (pH 6.4), while brynza was characterized by the highest acidity – 260 °T (pH 4.9). According to microbiological parameters, all specimens were characterized by the presence of pathogenic microflora. In particular, 1, 3, 5–9, 11–15 samples showed Staphylococcus aureus, 10 sample of Staphylococcus epidermis, 2 sample of bacteria of the genus Salmonella, 16 sample of Enterobacter aerogenes, and 4 samples of mold.
