It's not the best "microbiology" art, but it has a very interesting background. Two bacteria from two different clinical cases were inoculated on the TSCB medium. This metallic blue spilling bacterium is of course Pseudomonas aeruginosa. The yellow one (positive reaction on TSCB medium) is Vibrio metschnikovii isolated from chronic UTI in a dog. It was an unusual microbiological diagnosis. But what can you do when even your dog has a better holiday than you? Problems with urination (in this dog) began just after returning from the Mediterranean, the owners and the dog intensively used the charms of warm and salty water.

On March 11th 1955 Sir Alexander Fleming died.

Alexander Fleming discovered penicillin, whose use has saved untold millions of lives. Less well-known is that before making this world-changing discovery, he had already made significant contributions to medical science.

In 1914 World War 1 broke out and Fleming, aged 33, joined the army, becoming a captain in the Royal Army Medical Corps, working in field hospitals in France.

There, in a series of brilliant experiments, he established that antiseptic agents used to treat wounds and prevent infection were actually killing more soldiers than the infections were!

The antiseptics, such as carbolic acid, boric acid and hydrogen peroxide, were failing to kill bacteria deep in wounds; worse, they were in fact lowering the soldier’s natural resistance to infection because they were killing white blood cells.

Fleming demonstrated that antiseptic agents were only useful in treating superficial wounds, but were harmful when applied to deep wounds.

Almroth Wright, Flemings mentor, believed that a saline solution – salt water – should be used to clean deep wounds, because this did not interfere with the body’s own defenses and in fact attracted white cells. Fleming proved this result in the field. They published their results, but most army doctors refused to change their ways, resulting in many preventable deaths.

Today Penicillin is not as robust at fighting antibodies as it once was, Fleming warned of this in his Nobel Prize winning speech in 1945 when he said "“It is not difficult to make microbes resistant to penicillin in the laboratory by exposing them to concentrations not sufficient to kill them, and the same thing has occasionally happened in the body. The time may come when penicillin can be bought by anyone in the shops. Then there is the danger that the ignorant man may easily underdose himself and by exposing his microbes to non-lethal quantities of the drug make them resistant.”

Alexander Fleming died aged 73 of a heart attack in London on this day in955. His ashes were placed in St Paul’s Cathedral.

Where can a microbiologist work in Nigeria 2022?

Where can a microbiologist work in Nigeria is one question that drives away potential students from studying microbiology. Due to this negative effect, microbiologists are becoming scarce in the health industry. Microbiology is the study of microorganisms and other forms of microscopic life. Bacteria, fungi, algae, viruses, prions, and other nonliving biological particles are all studied in…

I am pleased to inform, that an article of which I am a co-author has just been accepted.

Thank you Dr. Marta Dec for the opportunity to cooperate. At the same time, this is my last article with the affiliation of the University of Life Sciences in Lublin. Fortunately, there will never be such cooperation again :) This is a bit of a sentimental article for me - the strains used in it, I collected as a veterinary student, later as a doctor and employee of the University of Life Sciences in Lublin. It is an interesting end to a career. It's also funny that I'm ending my career with the most veterinary bacteria.

On March 11th 1955 Sir Alexander Fleming died.

The discovery of penicillin came in September 1928, when Fleming was forty-seven. His account of it has been questioned and he did not make a note about it at the time, but according to his recollection he returned from holiday to his cramped little lab to find a pile of petri dishes, on which he had been growing colonies of bacteria, still waiting to be cleaned. He noticed that on one of them a mould had grown which had inhibited the growth of a colony of staphylococcus germs. The mould was Penicillium notatum, commonly found on bread, and Fleming called the liquid from it penicillin.

The thing is Oor Alexander could not find any important practical use for penicillin. He wrote a paper about it in the British Journal of Experimental Pathology, but it attracted no attention. He later pointed out that there had been no trained chemist in the St Mary’s lab. Sir Henry Dale summed up in the Dictionary of National Biography that ‘neither the time when the discovery was made nor, perhaps, the scientific atmosphere of the laboratory in which he worked, was propitious to such further enterprise as its development would have needed.’

t was not for another ten years or so that penicillin’s astonishing properties were established at Oxford by the Australian professor of pathology, Howard Florey, a Jewish refugee from Nazi Germany named Ernst Chain and an Englishman called Norman Heatley. They followed up Fleming’s original paper and turned their Oxford department into a prototype penicillin factory.

The relationship between them and Fleming was distinctly prickly. Almroth Wright wrote to The Times in 1942 claiming the credit for penicillin for Fleming and St Mary’s, and Fleming, Florey and Chain shared the Nobel Prize for Medicine in 1945.The media made Fleming the hero of the saga, partly because the accidental discovery was a good story and partly because Florey had no time for the press while Fleming was pleasant and approachable, your archetypical genial Scot.

A national hero he duly became. So much so that after his death at his home in Chelsea in 1955, his ashes were interred close to Nelson and Wellington in the crypt of St Paul’s Cathedral. Flags flew at half- mast and the cathedral bulged with academic and medical grandees, ambassadors, representatives of societies, staff and students from the hospital, as well as personal friends. A memorial plaque was unveiled in the crypt the following year and Fleming’s original lab where penicillin was discovered is preserved in the museum to him at St Mary’s.
