September 28 is the 271st day of the year (272nd in leap years) in the Gregorian calendar. There are 94 days remaining until the end of the year.

On this day in 1928, the antibiotic Penicillin was discovered. It’s discovery is attributed to Scottish scientist and Nobel laureate Alexander Fleming in 1928. He showed that, if Penicillium notatum  was grown in the appropriate substrate, it would exude a substance with antibiotic properties, which he dubbed penicillin. This serendipitous  observation began the modern era of antibiotic discovery. The development of penicillin for use as a medicine is attributed to the Australian Nobel laureate Howard Walter Florey together with the German Nobel laureate Ernst Chain and the English biochemist Norman Heatley.

However, several others reported the bacteriostatic effects of Penicillium earlier than Fleming. The use of bread with a blue mould (presumably penicillium) as a means of treating suppurating wounds was a staple of folk medicine in Europe since the Middle Ages. The first published reference appears in the publication of the Royal Society in 1875, by John Tyndall. Ernest Duchesne documented it in an 1897 paper, which was not accepted by the Institut Pasteur because of his youth. In March 2000, doctors at the San Juan de Dios Hospital in San José, Costa Rica published the manuscripts of the Costa Rican scientist and medical doctor Clodomiro (Clorito) Picado Twight (1887-1944). They reported Picado’s observations on the inhibitory actions of fungi of the genus Penicillium between 1915 and 1927. Picado reported his discovery to the Paris Academy of Sciences, yet did not patent it, even though his investigations started years before Fleming’s. Joseph Lister was experimenting with penicillum in 1871 for his Aseptic surgery. He found that it weakened the microbes but then he dismissed the fungi.

Fleming recounted that the date of his discovery of penicillin was on the morning of Friday, September 28, 1928. It was a fortuitous accident: in his laboratory in the basement of St. Mary’s Hospital in London (now part of Imperial College), Fleming noticed a petri dish containing Staphylococcus plate culture he had mistakenly left open, which was contaminated by blue-green mould, which had formed a visible growth. There was a halo of inhibited bacterial growth around the mould. Fleming concluded that the mould was releasing a substance that was repressing the growth and lysing the bacteria. He grew a pure culture and discovered that it was a Penicillium mould, now known to be Penicillium notatum. Charles Thom, an American specialist working at the U.S. Department of Agriculture, was the acknowledged expert, and Fleming referred the matter to him. Fleming coined the term “penicillin” to describe the filtrate of a broth culture of the Penicillium mould. Even in these early stages, penicillin was found to be most effective against Gram-positive bacteria, and ineffective against Gram-negative organisms and fungi. He expressed initial optimism that penicillin would be a useful disinfectant, being highly potent with minimal toxicity compared to antiseptics of the day, and noted its laboratory value in the isolation of “Bacillus influenzae” (now Haemophilus influenzae). After further experiments, Fleming was convinced that penicillin could not last long enough in the human body to kill pathogenic bacteria, and stopped studying it after 1931. He restarted clinical trials in 1934, and continued to try to get someone to purify it until 1940.

Spain has announced its budget that imposes more austerity that emphasizes spending cuts over revenue:

Government ministries saw their budgets slashed by 8.9 percent for next year, as Prime Minister Mariano Rajoy’s battle to reduce one of the euro zone’s biggest deficits was made harder by weak tax revenues in a prolonged recession. [..]

“This is a crisis budget aimed at emerging from the crisis … In this budget there is a larger adjustment of spending than revenue,” Deputy Prime Minister Soraya Saenz de Santamaria told a news conference after a marathon six-hour cabinet meeting.

Spain, the euro zone’s fourth largest economy, is at the centre of the crisis. Investors fear that Madrid cannot control its finances and that Rajoy does not have the political will to take all the necessary but unpopular measures.

Madrid is talking to Brussels about the terms of a possible European aid package that would trigger a European Central Bank bond-buying program and ease Madrid’s unsustainable borrowing costs. [..]

The measures continue to heap pressure on the crisis-weary population and are likely to fuel further street protests, which have become increasingly violent as tensions rise and police are given the green light to use force to disperse crowds.

A quarter of all Spanish workers are unemployed and tens of thousands have been evicted from their homes after a burst housing bubble in 2008 and plummeting consumer and business sentiment tipped the country into a four-year economic slump.

Analysis of the budget from Trevor Greetham at The Guardian‘s Live Blog compares Spain to the US and the UK:

I’ve always opposed austerity as the solution to the global debt crisis and the strictures of the common currency make it particularly ill-suited to the euro periphery. Efforts to deflate Spain into competitiveness raise the prospect of many years of wage cuts and property price falls that will necessitate ever larger fiscal transfers from the stronger countries, either directly or via pan-euro institutions like the central bank.

Five years into the worst financial crisis in generations we are starting to see how effective various policies have been. Spain, the UK and the US offer three interesting test cases, each dealing with the after effects of a real estate bust in different ways:

· Spain = austerity with tight money (austerity, no devaluation, no quantitative easing, market interest rates too high)

· UK = austerity but with loose money (austerity, currency devaluation, quantitative easing)

· US = no austerity with loose money (no austerity, stable currency, quantitative easing)

Activity in both the UK and Spain remains well below its pre-crisis level – suggesting the benefits of the UK printing its own currency may not be as great as might be supposed. It appears to be the lack of austerity in the US that is the distinguishing aspect of a successful policy mix.

With overall unemployment at 25% and the rising cost of food through increases in value added taxes (VAT), the many of the Spanish poor and unemployed have resorted to scavenging for food shocking many of their fellow citizens:

MADRID – On a recent evening, a hip-looking young woman was sorting through a stack of crates outside a fruit and vegetable store here in the working-class neighborhood of Vallecas as it shut down for the night.

At first glance, she looked as if she might be a store employee. But no. The young woman was looking through the day’s trash for her next meal. Already, she had found a dozen aging potatoes she deemed edible and loaded them onto a luggage cart parked nearby. [..]

Such survival tactics are becoming increasingly commonplace here, with an unemployment rate over 50 percent among young people and more and more households having adults without jobs. So pervasive is the problem of scavenging that one Spanish city has resorted to installing locks on supermarket trash bins as a public health precaution.

A report this year by a Catholic charity, Caritas, said that it had fed nearly one million hungry Spaniards in 2010, more than twice as many as in 2007. That number rose again in 2011 by 65,000. [..]

The Caritas report also found that 22 percent of Spanish households were living in poverty and that about 600,000 had no income whatsoever. All these numbers are expected to continue to get worse in the coming months.

About a third of those seeking help, the Caritas report said, had never used a food pantry or a soup kitchen before the economic crisis hit. For many of them, the need to ask for help is deeply embarrassing. In some cases, families go to food pantries in neighboring towns so their friends and acquaintances will not see them.

Expect to see more demonstrations like these as hunger increases:
