There are plenty of exciting finds this month so let’s dive straight in.
Researchers from China have discovered two new species of bacteria from two different species of Old World vulture in the Tibetan Plateau. Vultures may be a source of infectious pathogens as they feed on rotting carcasses and also scavenge the corpses from sky burials. To study the microbiome of vultures in this part of the world, the team live-captured wild birds and took rectal swabs, isolating the bacteria Actinomyces liubingyangii and Actinomyces vulturis.
A team from the US has isolated a bacterium from a timber rattlesnake in Minnesota, which they name Enterococcus crotali. Timber rattlesnakes are an animal we’ve written about before, as they’re one of the species that has been hit hard by snake fungal disease in North America.
In Japan, scientists have isolated an actinobacterium from the stone chambers of ancient burial mounds called ‘tumuli’. These circular structures in the Asuka village are thought to have been built in the 7th or 8th century, and the walls inside the stone chambers contain 1300-year-old mural paintings. Damage to these paintings may have been caused by the activity of micro-organisms, so the researchers have been carrying out microbial surveys of the site since 2004. Now, they report the discovery of Microbacterium tumbae, a microbe which colonised the plaster surface.
A couple of new archaea to highlight in this issue – Pyrobaculum igneiluti is a hyperthermophilic (extremely heat-loving) species isolated from a mud volcano in California, while Sulfodiicoccus acidiphilus is a thermoacidophilic (heat- and acid-loving) archaeon isolated from an acidic hot spring by a team in Japan.
Finally for this month, some bacteria from milk and honey. Researchers from SouthKorea have discovered two new species of bacteria living in the honeybee. Five bees were collected from a hive, and the novel species Paenibacillus apis and Paenibacillus intestini were isolated from their intestines. Meanwhile, microbiologists from Germany have isolated the species Pseudomonas lactis and Pseudomonas paralactis from raw cow’s milk. The team was researching the biodiversity and spoilage potential of milk microbiota.

Each year, the Royal Society of Biology organises ‘Parliamentary Links Day’, an event that brings together parliamentarians and the scientific community to discuss matters of importance to both. The 2017 event was attended by several Microbiology Society staff and members, including Dr Karen Robinson from the University of Nottingham, who gave us her thoughts about the day.
At the Microbiology Society’s Annual Conference 2017, Professor Michael Rossman from Purdue University was awarded our Prize Medal. You can watch his talk ‘A personal history of structural virology’ below. In this post, David Bhella gives an overview of Michael’s talk and the research it contains.
In April at the Microbiology Society Annual Conference 2017, Professor Steve Busby from the University of Birmingham was awarded the Marjory Stephenson Prize. He gave his talk on ‘Transcription activation in bacteria: ancient and modern’. In this post, Lorena Fernández-Martínez gives us an overview of the lecture, which you can watch below.
