Antony van Leeuwenhoek (FIGURE 1) also Dutch around 1668, she learned to grind lenses with great precision with which strands of hair noted, fleas and small insects, besides performing the first detailed description of red blood cells. Leeuwenhoek described different living beings, their sizes, they moved and how long they lived bacteria, algae and protozoa present in the waters of streams and ponds. These little beings were described as "animalcules". Starts from these facts, the history of microbiology. Built microscope by Leeuwenhoek. Source: This instrument has a magnification factor of approxi- you 275 times. Belongs to collection of microscopes of the University Museum of Utrecht, Netherlands.

Do you agree with this statement? Justify. What is the importance of the study of microbiology to humanity? THE ADVENTURE OF VIROLOGY! In 1898, Friedrich August Löffler, was tasked to investigate the FMD disease infecting cattle, producing ulcers in the mouth and hooves. Frosch and Paul Löffler tested tens of media for cultivating the agent of this disease in aerobic media in the presence of oxygen, and hydrogen using, hydrogen sulfide and carbon dioxide, for growing anaerobic bacteria. Failed to detect any bacteria. Nevertheless, the collected liquid vesicles infected when inoculated mucosa of calves transmitted disease. They decided to dilute the liquid in a type of filter that retained all bacteria. Tested to detect if there was any substance capable of immunizing animals. To their surprise, when the filtrate inoculated on calves rather than immunize them, the animals became sick and the infection spread. (Adapted from: RAW and SANT'ANA, 2002, p.120) Friedrich August Johannes Löffler (1852 - 1915) was a German bacteriologist at the Ernst Moritz Arndt University, Greifswald, Germany. Among their findings is the organism that causes diphtheria (Corynebacterium diphtheriae). Source: History of Medicine Library & Museum, http://clendening.kumc.edu Virus: "poisonous fluid"

Antony van Leeiwenhoek (SLIKA 1) i Nizozemski oko 1668, ona je naučila za mljevenje leće s velikom preciznošću s kojom pramenovi kose navedeno, buhe i male insekte, osim obavljanja prvi detaljan opis crvenih krvnih stanica. Leeiwenhoek opisao različite živa bića, njihova veličina, preselili su se i koliko dugo su živjeli bakterije, alge i protozoa prisutna u vodama potoka i bare. Ove male bića opisao kao "animalcules". Polazi od tih činjenica, povijesti za mikrobiologiju. Izgrađen mikroskopom Leeiwenhoek. Izvor: Ovaj instrument ima Faktor uvećanja aprok- da 275 puta. Pripada zbirci mikroskopa u sklopu Sveučilišta u Muzeju Utrechtu, Nizozemska. AKTIVNOST SLIKA 1 -. Antony van Leeiwenhoek (1632-1723) Znanstvenik zna za njegov doprinos u poboljšanju mikroskopom, te su pridonijeli svoje primjedbe na stanične biologije. Izvor: GNU Free License Doc, www.wikipedia.org "Poboljšanje sustava s optičkim sve poboljšao kvalitetu i bogatstvo detalja mikroskopskih slika, dakle, mikroskopi smatraju tehnologija u službi znanosti." Slažete li se s tom tvrdnjom? Opravdati. Kolika je važnost studije mikrobiologije za čovječanstvo? AVANTURA za virologiju! Godine 1898, Friedrich August Löffler, je zadatak da istraži FMD bolest zaraziti stoke, proizvodnju čirevi u ustima i kopita. Frosch i Paul Löffler testirani deseci medija za kultiviranje svog agenta o ovoj bolesti u aerobnim medija u prisutnosti kisika i vodika koriste, sumporovodik i ugljikov dioksid, za uzgoj anaerobnih bakterija. Nisam uspio otkriti sve bakterije. Ipak, prikupljaju tekućine vezikule okužen kada cijepljen sluznicu teladi prenosivih bolesti. Odlučeno je da se razrijediti tekućinu u vrsti filtra koji zadržane sve bakterije. Ispitano otkriti ima li tvar sposobna immunizing životinje. Na iznenađenje, kada filtrat cijepljen na teladi, a ne ih štititi, životinje postala bolesna i širenje infekcije.
