ZusammenfassungZiel: Ermittlung der Prävalenz prädisponierender Begleiterkrankungen (BE) bei Katzen mit bakteriellen Harnwegsinfektionen (HWI) und der Prävalenz von Bakterienspezies bei verschiedenen BE sowie deren Sensibilität gegenüber den bei HWI häufig eingesetzten Antibiotika Doxycyclin, Trimethoprim-Sulfamethoxazol (TMS), Amoxicillin-Clavulansäure (AMC), Cephalothin und Enrofloxacin. Material und Methoden: In die retrospektive Studie wurden Katzen mit positiver Urinkultur im Zeitraum 2003–2009 eingeschlossen. Basierend auf den Daten der Krankenakten erfolgte eine Einteilung in vier Gruppen: Katzen mit systemischen prädisponierenden BE, Katzen mit lokalen prädisponierenden BE, Katzen mit Harnblasendauerkathetern (HBDK) und Katzen ohne dokumentierte BE. Zur Ermittlung der wahrscheinlichen Effektivität der Antibiotika wurden deren antimikrobielle Impact-Faktoren berechnet. Ergebnisse: In die Studie gingen 194 Katzen mit 219 bakteriellen Isolaten ein. Davon wiesen 78,4% (152/194) eine BE auf. 49,5% (96/194) hatten eine systemische BE und 28,9% (56/194) hatten eine lokale BE oder einen HBDK. Katzen mit systemischen BE waren signifikant älter als Katzen der anderen Gruppen und häufiger weiblich als Katzen mit lokaler BE und HBDK. Mehr als 50% der Katzen mit systemischer BE zeigten keine klinischen Symptome einer Erkrankung des unteren Harntrakts. Escherichia (E.) coli, gefolgt von Streptococcus spp., Staphylococcus spp. und Enterococcus spp. waren die am häufigsten vorkommenden Isolate. Dabei lag der Anteil der E.-coli-Isolate bei Katzen mit systemischer BE signifikant höher, während bei Katzen mit HBDK und Katzen mit anderen lokalen BE der Anteil an Streptococcus- und Staphylococcus-spp.-Isolaten signifikant höher war. Bei Katzen mit lokaler BE und Katzen mit HBDK ergaben sich niedrigere antimikrobielle Impact-Faktoren als bei Katzen der anderen Gruppen. Schlussfolgerung und klinische Relevanz: Ein Großteil der Katzen mit HWI leidet unter einer prädisponierenden BE. Katzen mit systemischer BE zeigen häufig keine Symptome einer Erkrankung des unteren Harntrakts. AMC und TMS waren in dieser Katzenpopulation die Antibiotika mit den höchsten antimikrobiellen Impact-Faktoren.

This study was performed to investigate the distribution characteristics of airborne bacteria emitted from swine manure composting plants. The types of swine manure composting plants selected for the survey in this study were as follows: screw type, rotary type, and natural dry type. Mean levels of airborne bacteria in swine manure composting plants were 7428 (±1024) CFU m−3 for the screw type, 3246 (±1407) CFU m−3 for the rotary type, and 5232 (±1217) CFU m−3 for the natural dry type, respectively. Based on the results obtained from this study, the swine manure composting plant operated by screw type showed the highest concentration of airborne bacteria, followed by the natural dry type and rotary type. The monthly concentration of airborne bacteria was the highest in August and the lowest in November, regardless of the type of swine manure composting plant. The respirable size of airborne bacteria accounted for about 50% of the total. The ratio of respirable to the total quantity of airborne bacteria was 50%. The correlation relationships between airborne bacteria and environmental factors (temperature, relative humidity, particulate matters, and odor) were not found to be significant in the swine manure composting plants. The predominant genera of airborne bacteria identified were Micrococcus spp., Staphylococcus spp., Escherichia(E-coli) spp., Enterococcus spp., and Enterobacteriaceae spp.

Mastitis Pathogens

In many countries, bulk tank milk (BTM) has been used for examining milk and analyzed as an important part of milk quality assurance programs. The objectives of this study were to investigate milk quality and the presence of major mastitis pathogens in BTM, and to compare the characteristics of BTM by dairy factory or company. A total of 1588 batches of BTM samples were collected from 396 dairy farms of seven dairy factories owned by four companies in Korea. The means of individual bacterial counts (IBC) and somatic cell count (SCC) were 3.7 × 104 cells/mL and 1.1 × 105 cells/mL, respectively, and no significant differences among dairy factories were observed. The most common pathogen was Staphylococcus spp. (60.1%), followed by E. faecalis (53.8%), E. coli (37.6%) and Streptococcus spp. (22.5%). Enterococcus spp. showed the highest resistance to tetracyclines (51.1% to 73.9%) and macrolides (46.5%). S. aureus and coagulase-negative staphylococci (CNS) showed the highest resistance to penicillin (28.4% and 40.2%, respectively), and three (3.2%) S. aureus and seven (3.3%) CNS were also methicillin-resistant. These data show the diverse prevalence and characteristics of major mastitis pathogens among factories, and support the development of strong monitoring and prevention programs of mastitis pathogens by commercial dairy operations.

Abstract Introduction Identification of a causative agent in patients with infective endocarditis (IE) is crucial for diagnostic and prescribing etiotropic therapy which defines positive outcome of a disease. High rate of a culture negative IE and inaccurate results of traditional microbiological methods raise a concern. So the methods of etiological diagnostics in IE are in need of development, particularly introduction of polymerase chain reaction (PCR) method might be helpful. Aim Modernisation of the algorithm of IE etiological diagnostic by introducing PCR Materials and methods The study included 85 cases of IE [first episode of IE (n=79), recurrence/relapse (n=6)] verified by DUKE criteria 2009, 2015, hospitalized in Moscow primary hospital from 2012 to 2017. All patient had venous blood investigated both with microbiological method and with broadrange and specific PCR. Following microorganisms' DNA were assessed by PCR: Staphylococcus spp. (MRCoNS, S. aureus and others), Streptococcus spp. (S. agalactiae, S. pyogenes and others), Enterococcus spp. (E. faecium, E. faecalis and others), Enterobacteriaceae, Klebsiella spp. (K. pneumoniae and others), E. coli, Proteus spp., A. baumanii, P. aeruginosa, Fungi (C. albicans, C. glabrata, Aspergillus spp. and others). Results Median age was 55.48 years (95% confidence interval (CI) 51.16–59.8), males 67.9%. History of cardiovascular diseases was in 54 (68.35%), diabetes mellitus in 18 (22.78%), hepatitis B and/or C in 31 (39.2%), intravenous drug dependency in 27 (34.18%), chronic kidney disease in 38 (48.1%), median Charlson comorbidity index was 5.44 (95% CI 4.52–6.37). Left-side IE was in 50 (63.29%), right-side IE – in 23 (29.12%), left-right-side IE in 6 (7.59%). Secondary IE was in 53 patients (62.3%). Embolic events were diagnosed in 27 cases (34.18%), in-hospital mortality – in 22 (27.8%). Microbiological method identified etiological agent in 55 of 85 cases (61.2%), featuring Staphylococcus aureus (n=23), Staphylococcus CoNS (n=6), Escherichia coli (n=1), Acinetobacter spp. (n=2), Streptococcus spp. (n=2), Enterococcus spp. (n=8), Klebsiella pneumoniae (n=2), Gemella haemolysans (n=2), several causative agents (n=6). Additional PCR testing identified etiology in 14 of 33 (42.2%) featuring Staphylococcus spp. (n=6), Enterococcus spp. (n=3), Streptococcus spp. (n=1), Aspergillus sp. (n=1) Pasteurella multocida (n=1), Enterococcus spp. + Staphylococcus spp. (n=1), Staphylococcus spp.+ A. baumanii + E. coli (n=1). PCR method identified 6 fals-positive results of microbilogical investigation [S. epidermidis (n=2), G. haemolysans, Acinetobacter spp., E. faecalis, K. pneumoniae], that are most probably due to preanalytical sample contamination Conclusions Introduction of PCR into the algorithm of IE etiological diagnostic increased validity of laboratory findings on 23.5%. True culture negative IE was present in 19 of 85 patients. Rate of mortality and complications in IE remains high. FUNDunding Acknowledgement Type of funding sources: Public Institution(s).

Zusammenfassung Gegenstand und Ziel Die Prävalenz von antibiotikaresistenten Bakterien bei Zier-, Zoo- und falknerisch gehaltenen Greifvögeln ist noch weitgehend unbekannt. Daher sollten retrospektiv Antibiogramme schnellwachsender aerober Bakterienarten ausgewertet werden. Material und Methoden Im Auswertungszeitraum von 2007 bis 2016 standen 1036 Antibiogramme zur Verfügung. Die Bakterienisolate stammten vorzugsweise aus Süddeutschland und von 811 Vögeln aus 20 zoologischen Ordnungen (am häufigsten Papageienvögel [61,8 %] und Sperlingsvögel [14,5 %]) sowie aus Proben von klinischen Patienten und Sektionsmaterial. Die phänotypische In-vitro-Empfindlichkeit wurde mittels Plattendiffusionstest ermittelt. Ergebnisse Die meisten Antibiogramme lagen für E. coli (n = 386 Isolate) vor, gefolgt von Staphylococcus (S.). aureus (n = 150), Enterobacter cloacae (n = 122), Klebsiella pneumoniae (n = 86) und Pseudomonas aeruginosa (n = 64). Resistenzen gegen mindestens einen antibiotischen Wirkstoff zeigten 53,1 % der E. coli-Isolate, dabei am häufigsten gegen Doxycyclin (50,3 %) und Ampicillin (46,1 %). Bei 78,0 % der S. aureus-Isolate und bei 95,9 % der Enterococcus faecalis-Isolate wurden Resistenzen gegenüber mindestens einem Wirkstoff nachgewiesen. Multiresistenzen (Resistenz gegenüber ≥ 3 Antibiotikagruppen) traten bei 37,3 % der Isolate von S. aureus auf. Bei Isolaten von Zier- und Greifvögeln wurden höhere Resistenzraten festgestellt als bei Isolaten von Zoovögeln und bei Papageienvögeln höhere Resistenzraten als bei Sperlingsvögeln. Im Untersuchungszeitraum zeigte sich bei E. coli ein tendenzieller Anstieg der Resistenzrate für Fluorchinolone (Minimum von 0 % im Jahr 2013 und Maximum von 27,3 % im Jahr 2015) und bei S. aureus eine tendenzielle Abnahme der Resistenzraten für Tetrazykline (Maximum von 39,4 % im Jahr 2007 und Minimum von 0 % in den Jahren 2014 und 2015). Schlussfolgerung und klinische Relevanz Die Resistenzsituation von Bakterien aus Zier-, Zoo- und falknerisch gehaltenen Greifvögeln ist als problematisch zu bewerten und verdeutlicht die Wichtigkeit der Empfindlichkeitsprüfung für eine gewissenhafte Therapie. Im Fall einer Infektion mit S. aureus bei Zier-, Zoo- oder falknerisch gehaltenen Greifvögeln kann es zu einem Therapienotstand kommen.

Introducción: Las infecciones del tracto urinario (ITU), constituyen una de las infecciones bacterianas más prevalentes, sus agentes etiológicos incluyen Escherichia coli, Klebsiella spp, Proteus spp, Enterococcus spp, Pseudomonas spp y Staphylococcus spp, los cuales presentan prevalencias y perfiles de susceptibilidad antibiótica diferentes entre poblaciones. Objetivo: Determinar la prevalencia de ITU, uropatógenos y el perfil de susceptibilidad antimicrobiana en una Institución Prestadora de Servicios de Salud (IPS) de Medellín, 2011-2012. Métodos: Estudio de prevalencia en 1.959 individuos atendidos en una IPS de tercer nivel. Se calcularon medidas de resumen, proporciones, razones de prevalencia, Chi cuadrado y Fisher. Se cuantificó la modificación del efecto (confusión o interacción) con análisis estratificado y modelos de regresión logística binaria en SPSS 21.0®. Resultados: La prevalencia de ITU fue 31% los principales agentes etiológicos fueron E. coli (69%), Enterococcus spp (11%) y Klebsiella spp (8%). La ITU y la infección por E. coli fueron estadísticamente mayores en mujeres y adultos mayores. La mayor frecuencia de resistencia de E. coli fue para ampicilina (61%), Ácido nalidixico (48%), TrimetropinSulfa (48%) y Ciprofloxacina (42%); mientras que en Klebsiella spp fue Ampicilina (100%), TrimetropinSulfa (23%), Ampicilina- Sulbactam (22%) y Cefalotina (19%). Conclusión: La elevada prevalencia de ITU, la multiplicidad de uropatógenos aislados, la identificación de grupos de mayor riesgo y la diversidad de perfiles de resistencia antibiótica, evidencian la necesidad de desarrollar investigaciones locales que permitan orientar las acciones en salud y vigilancia epidemiológica, acordes con las particularidades de cada población.

As infecções bacterianas do trato urinário (ITUs) são causa comum de doença em cães, gatos e humanos. Embora bactérias Gram positivas como Staphylococcus spp., Streptococcus spp. e Enterococcus spp., possam ocasionar ITUs, as bactérias Gram negativas (Escherichia coli, Proteus spp., Klebsiella spp., Pseudomonas spp. e Enterobacter spp.) respondem por 75% dos casos. Este estudo teve como objetivo determinar a frequência de diferentes gêneros de bactérias em ITUs em cães e gatos, bem como a sua sensibilidade aos antimicrobianos utilizados na rotina clínica. Portanto, amostras de urina de 100 cães e gatos com sinais de ITU foram coletadas assepticamente, sofrendo avaliação microbiológica por meio de métodos qualitativos e quantitativos, além de urinálise. Todos os isolados foram submetidos a testes de sensibilidade aos antimicrobianos. ITU foi confirmada em 74% dos animais, não havendo predominância quanto ao sexo. No que diz respeito à idade, 85% dos cães e 87% dos gatos tinham idades superiores a seis anos. Noventa e cinco cepas bacterianas foram isoladas, com maior frequência de Escherichia coli (55% do total) dos sorogrupos O6 e O2. Constatou-se níveis elevados de resistência a antimicrobianos nas cepas isoladas. Para as cepas Gram positivas, tetraciclina (46,1%), enrofloxacina, cotrimazol e estreptomicina (42,3% cada) foram as drogas com os maiores índices de resistência. Para as Gram negativas, amoxacilina e tetraciclina apresentaram percentuais acima de 50%. Multiresistência foi verificada em mais de 50% dos principais gêneros isolados. Considerando-se que as cepas de E. coli apresentam potencial zoonótico e forte participação na disseminação de resistência aos antimicrobianos, ressalta-se a importância do papel do médico veterinário na prevenção e controle das ITUs animais e sua contribuição para a saúde pública.

Zusammenfassung Gegenstand: Retrospektive Untersuchung der mittels bronchoalveolärer Lavage (BAL) gewonnenen Keimflora der tiefen Atemwege erkrankter Hunde auf ihre Antibiotikaempfindlichkeit über 5 Jahre. Material und Methoden: Auswertung der Ergebnisse der Agardiffusionstests von Bakterienisolaten, die in den Jahren 2004–2009 von 84 Hunden isoliert wurden, und Vergleich mit den Resultaten einer gleichartigen Analyse der Jahre 1999/2000. Ergebnisse: Bei den 99 geprüften Bakterienisolaten handelte es sich um Pasteurella spp. (27,3%), Bordetella bronchiseptica (20,2%), Staphylococcus spp. (18,2%), Escherichia coli (15,2%), Klebsiella spp. (8,1%), Pseudomonas spp. (7,0%) und Streptococcus spp. (4,0%). Bei acht Hunden lagen Mischkulturen vor. Die Mehrzahl der Bordetella-(B.-)bronchiseptica-Isolate erwies sich als sensibel gegenüber den Fluorchinolonen sowie Tetracyclin, Doxycyclin und Polymyxin B. Im Vergleich zu 1999/2000 zeigte sich ein höherer Anteil der gegenüber Amoxicillin/Clavulansäure und Chloramphenicol empfindlichen B.-bronchiseptica-Isolate, wobei die Zunahme bezüglich Chloramphenicol statistisch signifikant war. Die überwiegende Anzahl der Staphylococcus-Isolate erwies sich gegenüber Enrofloxacin, Marbofloxacin, Amoxicillin/Clavulansäure, Chloramphenicol, Cephalexin, Doxycyclin und Polymyxin B sensibel. Im Vergleich zu 1999/2000 ergab sich ein erhöhter Anteil an Chloramphenicolund Tetracyclin-sensiblen Staphylococcus-Isolaten. Der Anteil Enrofloxacin-sensibler KlebsiellenIsolate betrug 62,5%, während er 1999/2000 bei 100% lag. Eine Sensibilität aller getesteten Klebsiellen-Isolate ließ sich noch gegenüber Polymyxin B nachweisen. Kein Antibiotikum zeigte eine Wirksamkeit gegenüber allen E.-coli-Isolaten. Statistisch signifikant war die Abnahme der gegenüber Amoxicillin/Clavulansäure-sensiblen Isolate. Schlussfolgerung und klinische Relevanz: Die Studie unterstreicht den Nutzen der BAL für eine ätiologische Diagnostik und den anschließenden fundierten Einsatz von Antibiotika. Die Mehrzahl der Bakterienisolate erwies sich als empfindlich gegenüber den Fluorchinolonen.

Context: Footwear should be designed to avoid trauma and injury to the skin of the feet that can favor bacterial and fungal infections. Procedures and substances for sanitizing the interior of shoes are uncommon but are important aspects of primary prevention against foot infections and unpleasant odor. Objective: To evaluate the efficacy of a sanitizing technique for reducing bacterial and fungal contamination of footwear. Design: Crossover study. Setting: Mens Sana basketball team. Patients or Other Participants: Twenty-seven male athletes and 4 coaches (62 shoes). Intervention(s): The experimental protocol required a first sample (swab), 1/shoe, at time 0 from inside the shoes of all athletes before the sanitizing technique began and a second sample at time 1, after about 4 weeks, April 2012 to May 2012, of daily use of the sanitizing technique. Main Outcome Measure(s): The differences before and after use of the sanitizing technique for total bacterial count at 36°C and 22°C for Staphylococcus spp, yeasts, molds, Enterococcus spp, Pseudomonas spp, Escherichia coli, and total coliform bacteria were evaluated. Results: Before use of the sanitizing technique, the total bacterial counts at 36°C and 22°C and for Staphylococcus spp were greater by a factor of 5.8 (95% confidence interval [CI] = 3.42, 9.84), 5.84 (95% CI = 3.45, 9.78), and 4.78 (95% CI = 2.84, 8.03), respectively. All the other comparisons showed a reduction in microbial loads, whereas E coli and coliforms were no longer detected. No statistically significant decrease in yeasts (P = .0841) or molds (P = .6913) was recorded probably because of low contamination. Conclusions: The sanitizing technique significantly reduced the bacterial presence in athletes' shoes.

Accumulation of opportunistic pathogenic bacteria in the aquatic environment may lead to the changes in the structure of the surface cover microbiocenosis as well as the fish intestinal tract. In its turn, it causes the growth of pathological processes in the fish organism, reduces the barrier functions of tissues and mucus and, as a consequence, may induce the spread of bacterial infections. Thus, assessing the state of fish organism, it is necessary to take into account the analysis of the epizootic situation in water (i.e. presence of infectious and invasive diseases of fish, death of fish) as well as condition of the skin, gills and gastrointestinal tract. The results of bacteriological studies of washes from the skin, gills and intestines showed that in the conditions of farming among rainbow trout of different age groups, E. coli, low fermented E. coli, Enterobacter spp., Klebsiella pneumoniae, Staphylococcus spp., Flavibacterium spp., Enterococcus spp. and Citrobacter spp. For the purposes of determining the sensitivity of isolated cultures to antibacterial drugs, it was found that Enterobacteriaceae are sensitive to enrofloxacin, cotrimoxazole, doxacillin, chloramphenicol, gentamicin, ceftriaxone, cefoperazone, ceftazidime and cefpiromycin and resistant to oxytetracycline, amoxicillin and ampicillin sulbactam. E. coli also demonstrated resistance to amoxicillin and cefpirome and sensitivity to enrofloxacin, oxytetracycline, cotrimoxazole, doxacillin, chloramphenicol, ampicillin sulbactam, gentamicin, ceftriaxone, cefoperazone, ceftazidime. Klebsiella pneumoniae was resistant to enrofloxacin, amoxicillin and ampicillin sulbactam, while Flavobacteriaceae were resistant to amoxicillin and ampicillin sulbactam and sensitive to all other antibacterial drugs. Key words: rainbow trout, microflora, skin, gills, intestines, antibacterial agents, resistance, sensitivity.
