“…In contrast, the Clostridiales in spotted hyena pastes were primarily members of the genera Anaerococcus, Clostridium, Fastidiosipila, Finegoldia, Murdochiella, Peptoniphilus, and Tissierella. Spotted hyena pastes also consistently contained fermentative genera outside the phylum Firmicutes, such as Corynebacterium, Propionibacterium (both Actinobacteria), Porphyromonas (Bacteroidetes), and Fusobacterium (Fusobacteria) (28)(29)(30)(31)(32)(33). At an OTU level, only 11 of 461 OTUs were shared between the pastes of adult spotted hyenas and those of adult striped hyenas from at least one population.…”

“…The bacteria in hyena pastes belong to clades of fermentative bacteria whose metabolisms yield varying amounts of acetic, propanoic, isobutanoic, butanoic, isopentanoic, isohexanoic, and hexanoic acids (28)(29)(30)(31)(32)(33). These differences suggest that variation in the structure of paste bacterial communities should result in variation in the structure of paste VFA profiles.…”

All animals harbor beneficial microbes. One way these microbes can benefit their animal hosts is by increasing the diversity and efficacy of communication signals available to the hosts. The fermentation hypothesis for mammalian chemical communication posits that bacteria in the scent glands of mammals generate odorous metabolites used by their hosts for communication and that variation in host chemical signals is a product of underlying variation in the bacterial communities inhabiting the scent glands. An effective test of this hypothesis would require accurate surveys of the bacterial communities in mammals' scent glands and complementary data on the odorant profiles of scent secretions-both of which have been historically lacking. Here we use next-generation sequencing to survey deeply the bacterial communities in the scent glands of wild spotted and striped hyenas. We show that these communities are dominated by fermentative bacteria and that the structures of these communities covary with the volatile fatty acid profiles of scent secretions in both hyena species. The bacterial and volatile fatty acid profiles of secretions differ between spotted and striped hyenas, and both profiles vary with sex and reproductive state among spotted hyenas within a single social group. Our results strongly support the fermentation hypothesis for chemical communication, suggesting that symbiotic bacteria underlie species-specific odors in both spotted and striped hyenas and further underlie sex and reproductive state-specific odors among spotted hyenas. We anticipate that the fermentation hypothesis for chemical communication will prove broadly applicable among scent-marking mammals as others use the technical and analytical approaches used here.animal behavior | animal communication | microbiome

“…Thus, at this time it is difficult to evaluate particular bacterial species that have a specific potential to produce orthopedic-material-associated infections or to know what is needed for specific treatments (such as different durations of antibiotic therapy or the need of material removal). Moreover, recent identification of several new taxa and the increasing diversity of coryneform bacterial strains encountered in clinical specimens render phenotypic identification more difficult (1,11,13,26,27). Consequently, genotypic identification as an alternative or complementary method for bacterial taxonomy and for identification of new species (including Corynebacterium spp.)…”

“…The isolate grew well at 37°C in 5% CO 2 under strictly anaerobic conditions, but no growth was observed in air at 25°C, 37°C, or 42°C. Biochemical testing using carbohydrate (CHO) tube sugars, metabolic products of fermentation, cellular fatty acid (CFA) composition analysis, and 16S rRNA gene sequencing was performed as previously described (3,4). Acid was observed in CHO sugars containing galactose, glucose, glycogen, maltose, sucrose, and xylose.…”

Gardnerella vaginalis in women causes vaginitis or infections in other sites, such as the urinary tract, but is an infrequent cause of bacteremia. Bacteremia in men is very rare and is typically associated with immunocompromised states. Here we describe G. vaginalis bacteremia in a previously healthy man with renal calculi and urosepsis. CASE REPORTA 41-year-old male roofer with no prior medical problems presented with sudden onset of left flank pain. The pain was colicky in nature and not accompanied by fever, chills, urgency, or dysuria. A physical examination at the time of presentation was unremarkable. A computed tomography scan of the abdomen revealed a 6.5-mm kidney stone in the midpole of the kidney and a 3-mm calculus at the left vesicoureteric junction. Obstructive uropathy and perinephric stranding were noted. Urine biochemistry revealed slight hemoglobinuria. The patient underwent ureteroscopy the following day, and as no infection was thought to be present, no antibiotics were given. The distal ureteric calculus was not seen and was assumed to have passed spontaneously. Follow-up imaging demonstrated only the larger proximal stone. The patient was discharged from the hospital, but he returned 2 days later with worse flank pain. The computed tomography scan was repeated, and it demonstrated a 4-mm stone in the proximal left ureter, with small fragments remaining in the midpole of the kidney. Additional investigations revealed a leukocyte count of 16.0 ϫ 10 9 cells/liter (normal range, 4 ϫ 10 9 to 11 ϫ 10 9 cells/liter) with a predominance of neutrophils (absolute count, 12.6 ϫ 10 9 cells/ liter; normal count, 2 ϫ 10 9 to 5 ϫ 10 9 cells/liter). Creatinine was elevated at 148 mol/liter (normal range, 70 to 110 mol/ liter). The patient was readmitted for a repeat ureteroscopy. Prior to this procedure, the patient was febrile, with a temperature of 39.1°C and rigors. He appeared well otherwise, and his physical examination, including blood pressure, was unremarkable. Ciprofloxacin (400 mg intravenously every 12 h) was empirically started for presumed urosepsis. The patient's complete blood count was normal, and cultures of urine and blood (two sets, with 20 ml from one site for anaerobe and aerobic cultures and 10 ml from a second site for an aerobic bottle) were taken prior to initiation of antimicrobial therapy. The quantitative urine culture revealed 6.5 ϫ 10 7 CFU/liter of a ciprofloxacin-sensitive strain of Escherichia coli. On the fifth day of incubation, the aerobic blood culture from the first set was flagged positive by the automated BacT/Alert system. A subculture of the second blood culture set revealed the same organism. The hospital laboratory was unable to achieve a definitive identification of the blood culture isolate, so the isolate was sent to a reference center.The patient underwent a repeat ureteroscopy with lithotripsy and an extraction of the proximal stone. A ureteric stent was inserted, and it was removed the following week. The patient was treated with a 10-day course of oral cip...
