MMWR Booster #17: Notes from the Field: Burkholderia pseudomallei Detected in a Raccoon Carcass Linked to a Multi-state Aromatherapy-Associated Melioidosis Outbreak — Texas, 2022
Top 5 Takeaways
Burkholderia pseudomallei, the bacterium causing melioidosis, was detected in a raccoon carcass in Texas, linked to a multistate melioidosis outbreak from an imported aromatherapy spray.
The raccoon, exposed to the contaminated spray, developed acute neurologic symptoms and died, leading to concerns about environmental contamination by the pathogen.
Extensive environmental testing at the burial site revealed no evidence of B. pseudomallei in the soil or surrounding area, despite the raccoon testing positive for the bacterium.
This incident marks the first reported presumed melioidosis case in a raccoon and the first animal case linked to this particular outbreak.
The investigation highlights the importance of environmental assessments to prevent potential establishment of B. pseudomallei in non-endemic areas.

"write and submit an abstract for this paper" is my air of mystery not enough for you?
#its for an assignment to learn how to write an abstract for a paper and i HATE IT#i had to do it once before for a conference paper and it was AWFUL#i'm staring blankly at this paper like hm yeah burkholderia pseudomallei and quorum sensing. what else is there to say#the answer is much#blue talks

Why did you choose Burkholderia? Which disease/member of the genus inspired it?
a long, long time ago I did some research in the Cystic Fibrosis realm and thought Burkholderia (cepacia) was a neat bacteria (not to be infected with though). Here we are!

Giant Mesquite Bug (Thasus neocalifornicus)
The giant mesquite bug inhabits the Sonoran desert from southwestern Arizona to northern Mexico, also found in New Mexico and Texas. It is a leaf-footed bug of the true bug order. As their name suggests, these insects live and feed primarily on mesquite trees, on which they remain throughout their life cycle. Large clusters of these bugs feed on the soft tissues of the tree, such as new leaves, seed pods and young stems. Nymphs are brightly-coloured in red, white and black, while the adults' palette is more subdued.
The giant mesquite's first line of defense is the employment of noxious chemicals, especially among nymphs, which deter potential predators from eating them. The chemical's composition changes as the insect ages; nymphs produce various hexenals, while adults produce hexanal, hexanol and hexyl acetate. 4-oxo-(E)-2-hexenal, produced by immature giant mesquite bugs, is a cytotoxin and mutagen which works primarily as an insecticide. It can kill insects much bigger than the juvenile, such as mantises and tarantulas! It is suggested that the symbiotic bacteria Wolbachia are necessary to the production of this cytotoxin, but the exact mechanism is still unknown.
On the topic of helpful bacteria, the symbiotic bacterium Burkholderia is of large importance to the digestive health of the giant mesquite bug, contributing to nymphs' survival. This bacteria is absent in the eggs and some young nymphs, suggesting that it is acquired sometime after hatching!

What’s the grossest thing you’ve seen in regards to microbiology
ooooooooooooo nice i love this question. im gonna put this under cut incase like, anyone is eating their tea or something lol
so i was ('was' bc i'm not currently working there full time as i started grad school in september) always the person in the lab people take the grossTM stuff to bc nothing really phases me?
so i've cut up peoples necrotic fingers before to put onto agar plates, like used a bone saw to cut peoples femurs or whatever to make bone chip broths. the thing i think maybe made me the most like, 'okay no thanks' was the time i had to like, spread someones eyeball jelly onto an agar plate after i cut it open.
if youre talking about like which bacteria i think is the grossest then.......idk maybe like strep pyogenes bc it can give you necrotising fasciitis (basically flesh eating bacteria) or maybe burkholderia pseudomallei bc it gives you melioidosis and its also scary bc it just like...lives inside you dormant for years. also if we are going classic the smell of proteus sp. is gross.
#i realise this makes me sound like a real sicko#which is true#but like i didnt take like pleasure in doing any of this it's just someone had to do it u know lol#bacteria are mostly gross but also like cool lil single cell organisms with dumb little small genomes#that manage to do so much damage to public health worldwide#you gotta almost..admire it?

Giant phage holds promise as treatment for lung infections
Researchers have discovered a new bacterial killer that can target common lung infection caused by Burkholderia bacteria that has exciting potential for biotechnological applications.
The Burkholderia cepacia complex is a group of bacteria that can cause lung infections, which can be fatal for those with serious lung diseases, particularly Cystic Fibrosis. Infections caused by Burkholderia…

Burkholderia cepacia has rarely been reported in Antananarivo. We present a case of a 49-year-old male with chronic kidney disease, hemodialysis-dependent, who was admitted to the hospital because of dyspnoea, deterioration of the general state and fever. His past medical history includes chronic kidney disease, hypertension, diabetes and chronic global heart failure. Burkholderia cepacia was identified in blood culture. The Immuno-compromised state of the patient, the antimicrobial resistance of Burkholderia cepacia and the delay of positivity of blood cultures are discussed.

米酵菌酸 Bongkrekic Acid
最近台灣發生的疑似食物中毒事件，有很大的概率是由 粿仔條 料理上的米酵菌酸造成…
初步研讀相關資料後，要避免該高風險的毒素，就是對於濕式處理的米加工品製品和木耳等，要特別提高警覺。
米酵菌酸 Bongkrekic Acid 是由唐菖蒲伯克氏菌(Burkholderia gladioli)污染的呼吸毒素，屬於無色、無味的毒素，因此人難以察覺。它存在於保存不當的發酵米及米類製品，如河粉、腸粉、年糕、糯米湯圓等，另外，也可能存在於處理不當的木耳上。
該毒素耐高溫，即使食物煮熟，也不一定能避免中毒。
米酵菌酸中毒的症狀可能包括精神不振、頭暈、嗜睡、腹痛、嘔吐等，且在嚴重情況下，只需1毫克毒素就可能致命，致死率超過40%。目前也尚無有效解毒劑…

The inevitable fall.
(TW self harm, illness) This weekend has been a much needed spar break after an utterly horrible two weeks. I am so excited for Monday when I get to find out if I have liver failure and have to come off Kaftrio, while also finding out if after my month off Kaftrio where my lung function dropped 20% if I need to go into hospital for IV's for the first time in 4 years. If this is Burkholderia kicking in as well, then, well I am well and truly fucked.
I am sure I deserve it, but I haven't been this shit and low since 2017, even weed can't get my mind off it, I cannot drink for obvious reasons and I am on here blasting music to distract myself because all I can think about is cutting myself. I've managed to go 3 years without doing it, even had a tattoo to cover my inner scars but I don't why once it gets into my head it's so pervasive becoming all I can think about. I'm even rationalising it with, we're in a cold spell so I can keep my arms covered for a while.
I also don't think my Elliot Smith/Death cab/Smashing Pumpkins marathon is helping.

Tìm hiểu bệnh lép vàng trên lúa và cách ngăn ngừa
Bệnh lép vàng lúa còn được bà con nông dân gọi với một cái tên thân thuộc là “bệnh bắn máy bay”. Vì cây lúa khi bệnh hạt của chúng bị lép vàng, không chắc, bông nhẹ nên thẳng đứng, không quằn xuống được.
Viruss Burkholderia glumae (Pseudomonas glumae) là nguyên nhân trực tiếp gây bệnh lép vàng lúa. Virus gây bệnh lép vàng trên lá lúa xâm nhập vào lá sau đó bệnh lan ra toàn bộ cây lúa.
