Abstract

Enterococcus are recognized worldwide as significant nosocomial agents that have been continuously envolving to adapt to different niches and acquire resistance to several antibiotic classes. Vancomycin and gentamicin-resistant strains of E. faecalis and E. faecium have been associated with nosocomial human infections. Some epidemiological studies suggest the participation of pets as reservoirs of vancomycin and gentamicin-resistant Enterococcus strains. However, the role of companion birds as reservoirs of these strains has been poorly studied. In this study, 126 psittacine birds were evaluated and 26.9% carried Enterococcus spp., including the species E. faecalis, E. faecium, E. hirae, E. phoeniculicola, E. gallinarum and E. casseliflavus. The antibiotic resistance profile showed four high-level gentamicin-resistance (HLGR) strains. In addition, two strains presented intermediate levels of vancomycin resistance. Resistant strains were isolated from fecal and oropharynx samples of sick and clinically healthy birds, suggesting that psittacine birds may act as reservoirs of HLGR Enterococcus spp. However, sick birds appear to be more implicated in the enterococci transmission than healthy birds. RESUMO: Enterococcus são reconhecidos mundialmente como significantes agentes nosocomiais, que têm continuamente se adaptado a diferentes nichos e adquirido resistência a várias classes de antibióticos. Cepas de E. faecalis e E. faecium vancomicina e gantamicina-resistentes têm sido associadas a infecções nosocomiais em humanos. Alguns estudos epidemiológicos sugerem a participação de aves como reservatórios de cepas de Enterococcus vancomicina e gentamicina-resistentes. Entretanto, a relação das aves de companhia como reservatórios destas cepas tem sido pouco estudada. Neste estudo, 126 psitacídeos foram avaliados, e 26,9% destes eram portadores de Enterococcus spp., incluindo as espécies E. faecalis, E. faecium, E. hirae, E. phoeniculicola, E. gallinarum e E. casseliflavus. O perfil de resistência antibiótica mostrou quatro cepas com alto nível de resistência a gentamicina (ANRG). Além de duas cepas com nível intermediário de resistência a vancomicina. As cepas resistentes foram isoladas de amostras fecais e de orofaringe de aves doentes e clinicamente saudáveis, sugerindo que psitacídeos podem estar atuando como reservatórios para Enterococcus spp. com ANRG. Contudo, Aves doentes parecem estar mais relacionadas à transmissão de enterococcus, do que aves saudáveis.

Abstract

In many countries, the main reason for severely restricting or outright banning the land application of class B biosolids is the lack of risk assessment for adverse human health impacts. Among pathogens that are not often studied are helminth ova, including that of the Ascaris spp. Almost all of the knowledge about the persistence of Ascaris spp. ova in soils fertilized with biosolids is based on studies developed in North America, Europe, and Asia. These studies have almost always been conducted under temperate climate conditions, which may cause erroneous interpretations when the conclusions are extrapolated to tropical regions such as those found in Brazil. This team evaluated the persistence of viable Ascaris spp. ova in a sandy Quartzipsamment tropical soil, previously planted with Eucalyptus urophylla × Eucalyptus grandis hybrid (Eucalyptus urograndis) and fertilized with biosolids, over a 52-wk period. During the reporting period, the average temperature of soil and biosolids fluctuated between 15 and 30°C, and the average moisture of biosolids fluctuated between 60 and 90%. The estimated persistence time of viable Ascaris spp. ova after land application was estimated at close to 7 wk, indicating that ova may not be viable for as long as it has been shown to be in studies of more temperate areas. The relationship of temperature with persistence of viable Ascaris spp. ova in a tropical soil was stronger than moisture content, suggesting that temperature substantially contributed to their nonviability over the course of the experiment.

36. Evaluation of protein spectra cluster analysis for Streptococcusspp. identification from various swine clinical samples

Author

Matajira, Carlos E. C., Moreno, Luisa Z., Gomes, Vasco T. M., Silva, Ana Paula S., Mesquita, Renan E., Doto, Daniela S., Calderaro, Franco F., de Souza, Fernando N., Christ, Ana Paula G., Sato, Maria Inês Z., and Moreno, Andrea M.

Abstract

Traditional microbiological methods enable genus-level identification of Streptococcusspp. isolates. However, as the species of this genus show broad phenotypic variation, species-level identification or even differentiation within the genus is difficult. Herein we report the evaluation of protein spectra cluster analysis for the identification of Streptococcusspecies associated with disease in swine by means of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). A total of 250 S. suis–like isolates obtained from pigs with clinical signs of encephalitis, arthritis, pneumonia, metritis, and urinary or septicemic infection were studied. The isolates came from pigs in different Brazilian states from 2001 to 2014. The MALDI-TOF MS analysis identified 86% (215 of 250) as S. suisand 14% (35 of 250) as S. alactolyticus, S. dysgalactiae, S. gallinaceus, S. gallolyticus, S. gordonii, S. henryi, S. hyointestinalis, S. hyovaginalis, S. mitis, S. oralis, S. pluranimalium, and S. sanguinis. The MALDI-TOF MS identification was confirmed in 99.2% of the isolates by 16S rDNA sequencing, with MALDI-TOF MS misidentifying 2 S. pluranimaliumas S. hyovaginalis. Isolates were also tested by a biochemical automated system that correctly identified all isolates of 8 of the 10 species in the database. Neither the isolates of the 3 species not in the database (S. gallinaceus, S. henryi, and S. hyovaginalis) nor the isolates of 2 species that were in the database (S. oralisand S. pluranimalium) could be identified. The topology of the protein spectra cluster analysis appears to sustain the species phylogenetic similarities, further supporting identification by MALDI-TOF MS examination as a rapid and accurate alternative to 16S rDNA sequencing.

40. Molecular and antimicrobial susceptibility characterization of Globicatella sulfidifaciensisolated from sow's urinary tract infection

Author

Matajira, Carlos E. C., Moreno, Luisa Z., Gomes, Vasco T. M., Silva, Ana Paula S., Mesquita, Renan E., Amigo, Cristina R., Christ, Ana Paula G., Sato, Maria Inês Z., and Moreno, Andrea M.

Abstract

ABSTRACTBackground:The Globicatellagenus comprises Gram-positive, facultative anaerobic, α-hemolytic and catalase negative cocci morphologically and phenotypically very similar to Streptococcusand Aerococcusgenus which can lead to misidentification and underestimation of this pathogen. Globicatellaspecies have already been isolated from human and animals with heart and brain disorders. Their clinical relevance in animals, and its zoonotic potential, remains unknown due to the difficulty in their identification.Objective:To present the isolation, phenotypic and molecular characterization of G. sulfidifaciensfrom urinary tract infection in sows.Materials and Methods:Urine samples from 140 sows of two swine herds located in São Paulo State (Brazil) yielded the isolation of three presumptive G. sulfidifaciensstrains. Identification and species confirmation were done by MALDI-TOF MS and 16S rRNA sequencing. Strains were further characterized by single enzyme amplified fragments length polymorphism (SE-AFLP) and broth microdilution techniques.Results:All three isolates were confirmed as G. sulfidifaciens. The SE-AFLP genotyping resulted in distinct fingerprint patterns for each strain. All isolates presented high MIC values to tetracycline, sulphonamides, aminoglycosides and tylosin tartrate, which present high usage in human and animal medicine.Conclusions:Globicatella sulfidifacienscould be related to sporadic urinary tract infections in swine and appear to present alarming antimicrobial susceptibility profile. It is necessary to differentiate Streptococcus-like microorganisms in routine laboratory diagnostics for the correct identification of underestimated species potentially pathogenic to animals.

Abstract

Streptococcus suis remains an important challenge for the worldwide swine industry. Considering that Brazil is a major pork producer and exporter, proper monitoring of the pathogen and resistance rates are required. We present here the characterization of Brazilian S. suis strains isolated over a 15 year period by pulsed-field gel electrophoresis (PFGE) typing, capsular, virulence, and antimicrobial resistance profiling. Serotype prevalence revealed a predominance of serotype 2/½ followed by 3, 7, 1/14, 6, 8, 18, 28, and 27; the latter had not yet been reported in Brazil. Resistance profiling enabled the differentiation of nine profiles presenting resistance to three and up to eight antimicrobial classes. Even though an association between the most resistant strains and isolation year starting from 2009 was observed, a high frequency of multidrug-resistant strains isolated from 2001 to 2003 was also detected. This suggests that despite the isolation period, S. suis strains already presented high resistance selection pressure. A slight association of serotype 2/½ with some virulence profiles and PFGE pulsotypes was also identified. Nevertheless, no clonal dispersion or persistency of clones over the analyzed years and herds was detected. [ABSTRACT FROM AUTHOR]

Abstract

The presence of Escherichia coli in drinking water is an indication of fecal contamination and can represent a risk of waterborne diseases. Forty-nine E. coli strains isolated from different sources of drinking water (distribution system, well, spring and mineral water) were placed into the phylogenetic groups A (15 strains), B1 (19 strains), B2 (2 strains) and D (13 strains). Approximately 30% of the strains analyzed belonged to groups B2 and D, which usually include potentially extraintestinal pathogenic strains. Moreover, the assignment of the strains to different phylogenetic groups indicates that different contamination events occurred in these waters. These results were compared with the distribution of E. coli strains isolated from two rivers and two dams into the phylogenetic groups. A significant difference was observed when the distribution of drinking water strains into the phylogenetic groups was compared to the results obtained from the Guarapiranga Dam and the Jaguari and Sorocaba Rivers. The results obtained in this work suggest that PCR-based methods can be used for a rapid assessment of potentially pathogenic E. coli strains in water samples.
