It was investigated the changes of anti infearonic and anti lactofearinic activity of microorganisms of distal part of the pigs intestine for mixed nonmatodozic – protozoozic invasion. Established that the organism invasion of the ascaris association, balantidium and eymeria does not cause changes of anti infearonic activity in microorganisms of genus Bacteroides spp., Prevotella spp., Propionibacterium spp., Peptostreptococcus spp. and Fusobacterium spp., but increases it in Bifidobacterium spp. at 9.09% and Clostridium spp. at 22.22%, and decreases to 7.69% in Eubacterium spp. Compared with controls, infearonic activity of microorganisms selected from animals intestine from the 2nd group was higher in Citrobacter spp., Staphylococcus spp., Klebsiella spp. and Streptococcus spp. accordingly in 4.6, 4.5, 2.9 and 2.3 times. In colilact. «-» gem «-» and Enterococcus spp. the growth of investigated rate was 1.2 to 1.4 times. Thanks to the result of investigation of anti infearonic activity of obligate anaerobes selected from the distal intestine of pigs infested by the association of intestinal parasites, was set its growth in microorganisms of genus Bifidobacterium spp. and Bacteroides spp. to 33.3%, Prevotella spp. – to 29.2%, Clostridium spр. – to 64.0%, Eubacterium spp. – to 26.7%, Propionibacterium spp. – to 84.6% and Peptostreptococcus spp. – to 15.4%, compared with microorganisms selected from the intestines of agility pigs. Among MAFAnM the most compared, to control, anti lactofearinic activity was grown in bacteria of genus Citrobacter spp., Klebsiella spp. and Staphylococcus spp. accordingly in 7.8, 3.7 and 3.5 times. Less expressed growth of the indicator was found in bacteria of genus Candidaspp. – into 1.5 times, E. coli.lact. «-» gem «+» and Enterobacter spp. – 1.4 times, Lactobacillusspp. and Enterococcus spp. – 1.3 times and Streptococcus spp. – 1.2 times.

The changes in lipolytic, lysozyme and hemolytic activity of the intestinal microflora of piglets invaded with the association of ascaris, imyrium and balantidium have been studied. It has been established that among microorganisms isolated from the distal intestine of piglets, lipase is synthesized by Bacteroides spp., Prevotella spp., Clostridium sp. and Peptostreptococcus spp., E. coli lact. «-» hem +, Enterobacter spp., Streptococcus spp., Staphylococcus spp. and Candida spp. In pigs affected by ascaris, emerya, and balantidium, the number of strains producing lipase was higher compared to healthy ones, namely: Bacteroides spp. – by 20.2%, Prevotella spp. – by 3.7%, Clostridium spp. – 29.2% and Peptostreptococcus spp. – by 14.9%, Staphylococcus spp. – by 67.7%, Streptococcus spp. – by 19.1%, E. coli lact. «-» heme «+» – by 17.3%, Candida spp. – 16.5% and Enterobacter spp. – by 4.8%. Lysozyme activity was detected in Bifidobacterium spp., Lactobacillus spp. and Staphylococcus spp. Significant differences in the penetrance of lysozyme activity of microorganisms in healthy and affected by ascarids, imedium, and balantidias of piglets were observed in Lactobacillus spp. and Staphylococcus spp. (P < 0.001). At the same time, in piglets, compared with healthy animals, the number of Lactobacillus spp. Strains that showed lysozyme activity decreased, while Bifidobacterium spp. and Staphylococcus spp. – grew. Bifidobacterium spp., Eubacterium spp., Lactobacillus spp., E. coli lact. «+» Hem «-», Enterobacter spp. and Citrobacter spp. there is no ability to produce hemolysins. Among lactosonegative gastric sticks, all strains isolated from both healthy and sick pigs showed hemolytic activity. The associative influence of ascaris, imerium and balantidii, showed an increase in the penetrance of hemolytic activity in Bacteroides spp. – by 45.8%, Prevotella spp. – by 26.8%, Clostridium spp. – 42.1%, Propionibacterium spp. – 41.5%, Peptostreptococcus spp. – 29.1% and Fusobacterium spp. – by 16.4%, Klebsiella spp. – by 33.4%, Enterococcus spp. – by 69.6%, Streptococcus spp. – by 66.0%, Staphylococcus spp. – by 64.5% and Candida spp. – by 11.5%.

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 und Ziel Bakterielle Hautinfektionen kommen bei Reptilien häufig vor. Obwohl viele dieser Infektionen durch multifaktorielle Probleme verursacht werden, ist eine spezifische Behandlung nötig. Ziel der Studie war, das Keimspektrum und die Resistenzlage von aeroben Bakterien in Hautläsionen von Reptilien zu untersuchen. Material und Methoden Tupferproben dermaler Läsionen von 219 Reptilien wurden bakteriologisch untersucht (01/2017–06/2018). Die Identifizierung der Bakterien erfolgte anhand von Selektivnährböden, biochemischen Parametern sowie MALDI-TOF-MS, die Erstellung der Antibiogramme mittels Mikrodilutionsmethode. Ergebnisse Bei den insgesamt identifizierten 306 Keimisolaten handelte es sich überwiegend um gramnegative Spezies. Pseudomonas spp. (n = 48), Citrobacter spp. (n = 31, nur bei Schildkröten), aerobe Sporenbildner (n = 30), Aeromonas spp. (n = 20), Acinetobacter spp. (n = 20), Proteus spp. (n = 15), Staphylococcus spp. (n = 15), Klebsiella spp. (n = 13), Enterococcus spp. (n = 13) sowie Morganella spp. (n = 11) machten den Hauptteil aus, daneben konnten weitere gramnegative (n = 78) und grampositive (n = 12) Bakterienspezies identifiziert werden. Mischkulturen mit 2 (n = 80) oder mehr (n = 16) Keimen traten bei 96 Tieren auf. Von 208 der 306 Isolate wurden Antibiogramme erstellt. Gegenüber Enro- (E) und Marbofloxacin (M) waren viele Isolate sensibel (minimale Hemmkonzentration [MHK] in µg/ml ≤ Grenzwert), beispielsweise Pseudomonas spp. (E: 86,4 % MHK ≤ 0,5; M: 95,5 % MHK ≤ 1), Citrobacter spp. (E: 86,4 % MHK ≤ 0,5; M: 90,9 % MHK ≤ 1) und Aeromonas spp. (E: 75,0 % MHK ≤ 0,5; M: 100 % MHK ≤ 1). Trimethoprim/Sulfamethoxazol erwies sich als wirksam gegen die meisten Citrobacter- (90,9 % MHK ≤ 2/38) und Aeromonas- (75,0 % MHK ≤ 2/38) Isolate. Amikacin war wirksam gegen fast alle Pseudomonas spp. (97,7 % MHK ≤ 16), Citrobacter spp. (95,5 % MHK ≤ 16) sowie Aeromonas spp. (93,8 % MHK ≤ 16). Schlussfolgerung und klinische Relevanz Das Keimspektrum von Reptilienhautläsionen umfasst vor allem gramnegative Bakterien, deren klinische Relevanz für jeden Einzelfall abzuwägen ist. Viele Isolate dieser Studie waren sensibel für Fluorchinolone sowie Aminoglykoside. Da der Einsatz dieser Antibiotika zurückhaltend erfolgen sollte und gegenüber jeder getesteten Antibiotikagruppe auch resistente Isolate identifiziert wurden, wird eine Antibiogrammerstellung empfohlen.

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.

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.

The bacterial infection of post-operative wounds is a common health problem. Therefore, it is important to investigate fast and accurate methods of identifying bacteria in clinical samples. The aim of the study was to analyse the use of the MALDI-TOF MS technique to identify microorganism wounds that are difficult to heal. The most common bacteria are Escherichia coli, Staphylococcus spp., and Enterococcus spp. We also demonstrate the effect of culture conditions, such as the used growth medium (solid: Brain Heart Infusion Agar, Mueller Hilton Agar, Glucose Bromocresol Purple Agar, and Vancomycin Resistance Enterococci Agar Base and liquid: Tryptic Soy Broth and BACTEC Lytic/10 Anaerobic/F), the incubation time (4, 6, and 24h), and the method of the preparation of bacterial protein extracts (the standard method based on the Bruker guideline, the Sepsityper method) to identify factors and the quality of the obtained mass spectra. By comparing the protein profiles of bacteria from patients not treated with antibiotics to those treated with antibiotics based on the presence/absence of specific signals and using the UniProt platform, it was possible to predict the probable mechanism of the action of the antibiotic used and the mechanism of drug resistance.

The sanitary evaluation of equipment and hands is fundamental to investigate the presence of pathogens in the dairy industry. Then, this study aims to evaluate the sanitization of equipment, workers’ hands, raw and pasteurized milk in goat milk dairies in the Cariri region, state of Paraíba.  Collected 32 samples of four dairies represented by letters A, B, C, and D. The followings contents were analyzed: mesophiles, total and thermotolerant coliforms, Escherichia coli, Staphylococcus aureus, Samonella spp. and Listeria monocytogenes in the reception tank, pasteurization tank, packing machine, package, wall, workers’ hand, and each dairy’s raw and pasteurized milk. After isolation, 84 colonies were confirmed by MALDI TOF. The indicator microorganisms presented variations for the workers’ hands, while A and B stayed within the patterns. For the equipment, only dairy B was within limits. They were out of the standard for mesophiles, total coliforms, and thermotolerant regarding raw and pasteurized milk. The microorganisms, the Enterobacteriaceae family presented a higher frequency, with 77.38%, and within this family, Escherichia coli, Klebsiella spp., and Enterobacter spp. were the most prevalent. Gram-positive corresponded to 22.62%, Bacillus spp., Staphylococcus spp., Enterococcus spp., and Macrococcus caseolyticus. Listeria monocytogenes and Salmonella spp. were not isolated. These demonstrate failures in goat milk processing with pathogenic bacteria in several dairy plants, indicating the need to adjust the product’s quality control.
