Septische Arthritiden und Pneumonien gehören bei Mastkälbern zu den häufigsten Todesursachen. Septische Arthritiden oder Entzündungen der synovialen Einrichtungen haben v. a. traumatische Ursachen, entstehen durch periartikuläre Entzündungsprozesse oder infolge einer hämatogenen Erregerstreuung. Die in diesem Zusammenhang beim Rind gewöhnlich nachweisbaren Erreger sind Trueperella pyogenes, Streptococcus spp., Staphylococcus spp. und E. coli. Eine mögliche hämatogene Streuung bei bestehender Bronchopneumonie ist bekannt und oft mit dem Nachweis von Mycoplasma spp. assoziiert. In letzter Zeit häufen sich jedoch Berichte über die Beteiligung von Helcococcus ovis als neu aufkommendem Pathogen, meist in Form von Koinfektionen mit anderen Bakterien. In diesem Fallbericht wird eine Monoinfektion mit Helcococcus ovis bei Kälbern einer Milchviehherde dargestellt.

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.

Summary. Purpose of the reserche. To study changes in microflora and sensitivity of isolated strains to antibiotics using bacteriological research methods for intra-abdominal infections and peritonitis to determine their resistance when planning antibiotic therapy. Results and discussion. The paper presents data from a retrospective analysis of the results of studies of microflora and its resistance in intra-abdominal infections (IAI) and peritonitis for 2 periods: I period — from january 2007 to december 2008, II period — from january 2018 to december 2019. The difference between period II and I was in the increase in the number of individual pathogenic strains of microorganisms. Thus, the number of Klebsiella spp. increased from 13.8 % to 23.8 %, which in absolute number of their total number amounted to a 73.5 %, ranking second in the overall structure among pathogens sown in IAI and peritonitis. The number of strains of Staphylococcus spp., Enterobacter spp., Acinetobacter spp. has also increased by 2.4–5.8 % respectively. Among the strains Klebsiella spp., E. coli and Staphylococcus spp. the number of poly- and multi-polyresistant forms has increased. Thus, the number of such forms among Klebsiella spp. increased from 19.2 to 44.5 %, Staphylococcus spp. — from 43.8 to 67.1 % and E. coli from 18.2 to 23.5 %, respectively. Conclusions. Over the past 10 years, with IAI and peritonitis, the most significant changes were revealed on the part of pathogenic strains of Klebsiella spp., Staphylococcus spp. and Acinetobacter spp. Multidrug resistant strains were predominantly susceptible to carbapenems, semisynthetic ureidopenicillins, aminoglycosides, glycopeptides, oxazalidinones, phosphonoic acid derivatives. In the context of changes in the microbial landscape observed over the past decade, an increase in the number of poly- and multi-resistant forms of pathogenic microorganisms in IAI and peritonitis, the choice of antibiotics for rational therapy should be based solely on bacterioscopy and antibiograms.

Background: Urinary tract infections (UTIs) are one of the most common infections. For treatment of UTIs, there are limited antibiotics due to increased resistance among uropathogens. Two older antibiotics; Nitrofurantoin and Fosfomycin have become novel oral therapeutic options against uropathogens. Aim of the study was to identify UTI causing micro-organisms and evaluate in-vitro activity of nitrofurantoin and fosfomycin against most common isolated organism (E. coli).Methods: Results of urine samples culture and susceptibility testing over a period of 1 year were analysed and included in this study.Results: Micro-organisms were isolated from 568 urine samples. Most commonly isolated organism was Escherichia coli (40.50%), followed by Klebsiella spp. (20.07%) and Staphylococcus spp. (17.07%). Susceptibility of E. coli to nitrofurantoin and fosfomycin was 91.74% and 65.65% respectively. Conclusion: Good activity of nitrofurantoin and fosfomycin against E. coli indicates that these two drugs are potential therapeutic alternatives for urinary tract infections.

Abstract There is a paucity of research conducted on microbial prevalence in pheasants. The microbiota of captive birds has zoonotic significance and must be characterize. Present study is therefore planned to assess the microbiota from oral, fecal and gut content of captive avian species. It will be helpful in characterization of harmful microbes. Different samples taken from oral, gut and feces of ring-necked pheasants (Phasianus colchicus), green pheasants (Phasianus versicolor), golden pheasant (Chrysolophus pictus) and silver pheasant (Lophura nycthemera). Samples were collected, diluted, and inoculated onto different agar plates (MacConkey, SS agar, MSA and nutrient agar) for cultivation of bacterial species. Colonies of E.coli, Staphylococcus spp. Brachyspira spp. and Campylobacter spp were observed based on colony morphology. Colony forming unit showed E. coli as frequently found bacteria in fecal, oral and gut contents of all the above pheasants. The overall significance difference was found among bacterial species of golden pheasants, green pheasant, ring-necked pheasant, and silver pheasants. It was concluded that E.coli is predominant isolated from heathy pheasants followed by Campylobacter, Staphylococcus and Brachyspira.

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.

The effects of veterinary drugs, dietary supplements and non-protein amino acids on the European honey bee (Apis mellifera ligustica Spinola, 1806) ventriculum microbial profile were investigated. Total viable aerobic bacteria, Enterobacteriaceae, staphylococci, Escherichia coli, lactic acid bacteria, Pseudomonas spp., aerobic bacterial endospores and Enterococcus spp. were determined using a culture-based method. Two veterinary drugs (Varromed® and Api-Bioxal®), two commercial dietary supplements (ApiHerb® and ApiGo®) and two non-protein amino acids (GABA and beta-alanine) were administered for one week to honey bee foragers reared in laboratory cages. After one week, E. coli and Staphylococcus spp. were significantly affected by the veterinary drugs (p < 0.001). Furthermore, dietary supplements and non-protein amino acids induced significant changes in Staphylococcus spp., E. coli and Pseudomonas spp. (p < 0.001). In conclusion, the results of this investigation showed that the administration of the veterinary drugs, dietary supplements and non-protein amino acids tested, affected the ventriculum microbiological profile of Apis mellifera ligustica.

Fifty-one ready-to-eat street foods, 18 dishwater, and 18 surface swab samples were collected from six vendors in Johannesburg, South Africa. Food temperatures were recorded at the time of sampling. Standard methods were used to determine aerobic plate counts (APCs), spore counts (SCs), and Enterobacteriaceae counts (ECs) for food samples as well as coliform counts (CCs) for water and swab samples. In addition, Petrifilm Escherichia coli count (PC) plates were used for the enumeration of coliforms in food, water, and swab samples. The presence of selected foodborne pathogens in the food samples as well as the presence of nonpathogenic E. coli 1 (in food and water samples) was also tested for. Predominant colonies isolated from APC plates were characterized to the genus level. Holding temperatures for cooked meats and gravies ranged from 42.0 to 94.0°C, and those for uncooked salads ranged from 29.0 to 39.0°C. Mean APC values of 3.4 (±0.4) log CFU/g, 4.0 (±1.2) log CFU/ml, and 2.1 (±0.4) log CFU/25 cm2 were obtained for food, water, and swab samples, respectively. Mean SC values of 1.6 (±0.2) log CFU/g and 1.5 (±0.3) log CFU/25 cm2 were obtained for food and swab samples, respectively. A mean EC value of 2.0 (±0.4) log CFU/g for food samples and mean CC values of 2.5 (±0.3) log CFU/ml and 1.3 (±0.3) log CFU/25 cm2 for water and swab samples, respectively, were determined. Mean PC values of 1.6 (±0.1) log CFU/g, 1.9 (±0.6) log CFU/ml, and 1.4 (±0.4) log CFU/25 cm2 were determined for food, water, and swab samples, respectively. Bacillus cereus was detected in 22%, Clostridium perfringens in 16%, Salmonella spp. in 2%, and E. coli (non-O157:H+) in 2% of the 51 food samples. E. coli was found in 14 water samples (78%) and in 3 food samples (6%). Campylobacter spp., Listeria monocytogenes, Staphylococcus aureus, Vibrio cholerae, and Yersinia enterocolitica were also tested for in the food samples, but they were not detected. The 340 isolates obtained from APC plates for food, water, and swab samples were predominantly Bacillus spp., Micrococcus spp., and Staphylococcus spp. for all three sample types. It was concluded that the foods analyzed in this study were of acceptable quality and safety.

Nine hundred and fifty two milk samples from clinical bovine mastitis cases, originated from 269 farms in Northern Greece, were tested. Escherichia coli was isolated in 49.3% of samples. Furthermore, Staphylococcus spp, Corynebacterium spp, Streptococcus spp, Pseudomonas spp, Proteus spp, Klebsiella spp or a combination of the above bacteria were isolated. The bacteriological result from 4.3% of samples was negative. No correlation between clinical mastitis cases and seasonal variation was observed. Resistance of E. coli isolates to tetracycline was 82-96%, to enrofloxacin 10-30%, to gentamicin 58-80%, to cephalosporins 47-75%, to sulfamethoxazole-trimethoprime 46-81%, to ampicillin 71-92% and to neomycin 83-97%. The highest resistance rate and the appearance of multi-resistant isolates of E. coli (6%), to 8 antibacterials, were recorded during the last year of the survey.

A comercialização do leite sem tratamento térmico ou controle de inspeção sanitária é proibida por lei em todo o país, mas persiste principalmente em regiões interioranas. Assim, torna-se importante avaliar o leite nestas localidades, como forma de monitoramento do produto que será consumido pela população. Dessa forma, objetivou-se avaliar o diagnóstico microbiológico e o índice de adição de água em amostras de leite cru comercializado no município de Pombal, Paraíba. Foram coletadas três amostras de cada um dos cinco locais de comercialização, entre os meses de maio e junho de 2017. As mesmas foram obtidas em recipientes estéreis e avaliadas quanto aos parâmetros de Coliformes à 45ºC (NMP/mL), presença/ausência de Salmonella sp. e Escherichia coli, Staphylococcus spp. (UFC/mL) e Contagem total de bactérias Aeróbias Mesófilas (CTM) (UFC/mL). O índice de adição de água foi determinado através do equipamento Analisador de leite Master Classic. Todas as amostras apresentaram Coliformes à 45ºC (&gt;110 NMP/mL), presença de Salmonella sp. e E. coli, além de altas contagens de Staphylococcus spp. (3,13 x102 a 2,65 x105 UFC/mL) e CTM (2,30 x104 a 3,91 x105 UFC/mL). Observou-se amostras que apresentaram um índice de adição de água de aproximadamente 5%. O leite cru comercializado no município de Pombal mostrou-se fora dos padrões microbiológicos para todos os parâmetros analisados, além da existência de fraude em amostras pela adição de água, estando impróprio para o consumo.
