“…prevalence in poultry farms is sporadic [ 28 ]. The detected bacterial species belonging to the genera Corynebacterium , Haemophilus , Streptococcus , and Veillonella were potentially harmful to humans [ 29 – 39 ]. Moreover, the detected Aspergillus species are also potentially harmful to humans and broilers [ 40 – 42 ].…”

This study was conducted at one of the largest poultry companies in Kuwait during November and December 2019 to evaluate the microbiological threats of Escherichia coli (APEC), Salmonella spp., and Aspergillus fumigatus to chickens in fattening houses by counting and identifying the microorganisms by culturing and pyrosequencing analysis. During the fattening cycle, the temperature and humidity ranged between 23.6°C and 29°C and 64.1% and 87.1%, respectively. The total bacterial population and Aspergillus fumigatus measured in the indoor and outdoor air exhibited a linear relationship during the fattening cycle. The total bacterial and Aspergillus concentrations determined during the cycle ranged between 150 and 2000 CFU/m3 and 0 and 1000 CFU/m3, respectively. E. coli and Salmonella spp. concentrations determined during the cycle ranged between 1 and 220 CFU/m3 and 4 and 110 CFU/m3, respectively. Pyrosequencing analysis of the air inside the houses at the end of the cycle revealed extensive biodiversity in the microorganisms, detecting 32 bacterial genera and 14 species. The identified species belonging to the genera Corynebacterium, Haemophilus, Streptococcus, Veillonella, and Aspergillus were identified as potentially affecting human and broiler health. The emission of potentially pathogenic bacteria to the outdoor environment from chicken housing can pose a considerable risk to human health and environmental microbial pollution. This study could guide the development of integrated control devices for monitoring microbes in broiler production facilities during chicken collection for transport to slaughterhouses.

“…It is also important to notice that bacteremia for S. anginosus is mostly related to abscesses and it is rarely a contaminant when isolated from blood cultures [ 9 ]. For this reason, if S. anginosus is detected in blood cultures, antibiotics for anaerobic bacteria should be considered.…”

Streptococcus spp. and Enterococcus spp. are frequent etiologies of bloodstream infection and endocarditis. In recent years, the incidence of Enterococcus spp. has been increasing, especially with nosocomial involvement, and with a high mortality rate. In this entity, the risk of endocarditis and its relationship with colorectal neoplastic pathology remains to be clarified, in order to establish indications for echocardiography and colonoscopy. In the case of Streptococcus spp., the risk of endocarditis depends on the species and the mortality rates are usually lower. Finally, in recent years, the treatment of endocarditis has been directed towards oral consolidation regimens and new long-term antibiotic treatments.

Beyond the usual suspects: emerging uropathogens in the microbiome age

The advent of sensitive enhanced culture (metaculturomic) and culture-independent DNA-based (metagenomic) methods has revealed a rich collection of microbial species that inhabit the human urinary tract. Known as the urinary microbiome, this community of microbes consists of hundreds of distinct species that range across the entire phylogenetic spectrum. This new knowledge clashes with standard clinical microbiology laboratory methods, established more than 60 years ago, that focus attention on a relatively small subset of universally acknowledged uropathogens. Increasing reports support the hypothesis that this focus is too narrow. Single uropathogen reports are common in women with recurrent urinary tract infection (UTI), although wider disruption of their urinary microbiome is likely. Typical “UTI” symptoms occur in patients with “no growth” reported from standard culture and sometimes antibiotics improve these symptoms. Metaculturomic and metagenomic methods have repeatedly detected fastidious, slow growing, and/or anaerobic microbes that are not detected by the standard test in urine samples of patients with lower urinary tract symptoms. Many of these microbes are also detected in serious non-urinary tract infections, providing evidence that they can be opportunistic pathogens. In this review, we present a set of poorly understood, emerging, and suspected uropathogens. The goal is to stimulate research into the biology of these microbes with a focus on their life as commensals and their transition into pathogens
