Symbiotic microbes and potential pathogens in the intestine of dead southern right whale (Eubalaena australis) calves.

Anaerobe 2019 Apr 6;57:107-114. Epub 2019 Apr 6.

Southern Right Whale Health Monitoring Program, Chubut, 9120, Argentina; School of Veterinary Medicine, University of California Davis, California, 95616, United States.

Between 2003 and 2017, at least 706 southern right whale (Eubalaena australis) calves died at the Península Valdés calving ground in Argentina. Pathogenic microbes are often suggested to be the cause of stranding events in cetaceans; however, to date there is no evidence supporting bacterial infections as a leading cause of right whale calf deaths in Argentina. We used high-throughput sequencing and culture methods to characterize the bacterial communities and to detect potential pathogens from the intestine of stranded calves. Read More

Polymicrobial anaerobic meningitis caused by Bacteroides fragilis, Bacteroides thetaiotaomicron, Fusobacterium necrophorum and Slackia exigua in a patient with mastoiditis following otitis media.

Anaerobe 2019 Apr 14;56:95-97. Epub 2019 Feb 14.

Marmara University, School of Medicine, Department of Microbiology, Istanbul, Turkey.

We have reported a case of mastoiditis which progressed to meningitis in a 16-year old male patient. CSF (cerebrospinal fluid) anaerobic culture revealed four species of isolated anaerobic bacteria. This is the first case in the literature in which a patient survived childhood polymicrobial anaerobic meningitis diagnosed by MALDI-TOF MS (Matrix Assisted Laser Desorption Ionization - Time of Flight Mass Spectrometry).

Production of neutralizing antibodies against the secreted Clostridium chauvoei toxin A (CctA) upon blackleg vaccination.

Anaerobe 2019 Apr 14;56:78-87. Epub 2019 Feb 14.

Vetsuisse Faculty, University of Bern, Bern, Switzerland. Electronic address:

Clostridium chauvoei is the etiologic agent of blackleg in cattle, inducing fever, severe myonecrosis, oedemic lesions and ultimately death of infected animals. The pathogen often results in such rapid death that antibiotic therapy is futile and thus vaccination is the only efficient strategy in order to control the disease. The β-barrel pore forming leucocidin Clostridium chauvoei toxin A (CctA) is one of the best characterised toxins of C. Read More

Department of Diagnostic Medicine and Pathobiology, College of Veterinary Medicine, Kansas State University, Manhattan, KS, 66506, USA. Electronic address:

Fusobacterium necrophorum is a Gram negative, rod-shaped and aero tolerant anaerobe. In animals, it is an opportunistic pathogen frequently associated with necrotic infections, generally called necrobacillosis, such as calf diphtheria, foot rot and liver abscesses in cattle. Two subspecies exist: subsp. Read More

Challenges of next-generation sequencing targeting anaerobes.

Anaerobe 2019 Feb 12. Epub 2019 Feb 12.

Division of Oral Microbiology and Immunology, Department for Operative Dentistry, Periodontology and Preventive Dentistry, RWTH Aachen University Hospital, Aachen, Germany.

Next-generation sequencing allows for investigating the composition of microbiomes that are associated with infection (clinical microbiology) or dysbiosis (microbial ecology). The most commonly applied short-read sequencing technologies are Illumina MiSeq/HiSeq and Ion Torrent PGM, however, other platforms that generate long-reads are under way and optimized. A pre-condition for representative results is an appropriate method for contamination-free collection, homogenization, storage of specimens and a subsequent efficient DNA extraction protocol.

Is botulism type C transmissible to human by consumption of contaminated poultry meat? Analysis of a suspect outbreak in French Guyana.

Anaerobe 2019 Apr 12;56:49-50. Epub 2019 Feb 12.

National Reference Center for Anaerobic Bacteria and Botulism, Pasteur Institute, 75015, Paris, France. Electronic address:

Botulism type C was suspected in a 46-year old man after consumption of sick poultry from a flock where botulism type C was confirmed. The patient developed characteristic signs of botulism, but investigation of biological samples did not confirm the presence of Clostridium botulinum or botulinum toxin. Despite having classical botulism symptoms, the man recovered very quickly. Read More

Susceptibility of endometrial isolates recovered from women with clinical pelvic inflammatory disease or histological endometritis to antimicrobial agents.

The CDC recommended outpatient treatment of pelvic inflammatory disease (PID) is an intramuscular dose of ceftriaxone plus 14 days of doxycycline, with or without metronidazole. European guidelines (2017) include moxifloxacin plus ceftriaxone as a first line regimen, particularly for women with Mycoplasma genitalium-associated PID. However, the susceptibility of bacteria recovered from the endometrium of women with PID to moxifloxacin is unknown. Read More

Animal Nutrition Division, Indian Council of Agricultural Research - National Dairy Research Institute, Karnal, 132001, Haryana, India. Electronic address:

In the present study, we investigated the potential of Bifidobacterium spp., isolated from ruminal fluid samples from buffaloes (Bubalus bubalis) for conjugated linoleic acid (CLA) production. A total of 294 isolates were obtained from 86 ruminal fluid samples using Bifidus Selective Medium (BSM) medium, and based on phospoketolase assay, 24 isolates were presumptively confirmed to be Bifidobacterium species.

High prevalence of division II (cfiA positive) isolates among blood stream Bacteroides fragilis in Slovenia as determined by MALDI-TOF MS.

Anaerobe 2019 Feb 1. Epub 2019 Feb 1.

Department of Infectious Diseases, University Medical Centre Ljubljana, Ljubljana, Slovenia.

Bacteroides fragilis can be classified into division I (cfiA negative) and division II (cfiA positive) isolates. Division II isolates have a silent chromosomal carbapenemase gene (cfiA) that can become overexpressed by an insertion of a mobile genetic element and thus develop a phenotypic resistance to carbapenems. Aims of our study were (i) to determine the prevalence of B. Read More

Molecular epidemiology of Clostridioides (previously Clostridium) difficile isolates from a university hospital in Minas Gerais, Brazil.

Anaerobe 2019 Apr 29;56:34-39. Epub 2019 Jan 29.

Escola de Veterinária, Universidade Federal de Minas Gerais (UFMG), Av. Antônio Carlos, 6627, Belo Horizonte, MG, CEP 31.270-901, Brazil. Electronic address:

The molecular epidemiology of 38 non-duplicate toxigenic Clostridioides (previously Clostridium) difficile isolates from inpatients from a hospital in Brazil during a 6-year period (2012-2017) were investigated by multilocus sequence typing (MLST) and ribotyping. These isolates were classified into 20 sequence types (ST), six (30%) of which were novel, revealing a high diversity in a single hospital. Classic hypervirulent strains ST1/RT027 and ST11/RT078 were not identified, while ST42 (almost all RT106) was the most common type, being detected in 11 (28. Read More

We investigated inflow of a wastewater treatment plant and sediment of an urban lake for the presence of Clostridioides difficile by cultivation and PCR. Among seven colonies we sequenced the complete genomes of three: two non-toxigenic isolates from wastewater and one toxigenic isolate from the urban lake. For all obtained isolates, a close genomic relationship with human-derived isolates was observed. Read More
