Campylobacter jejuni is previously called as Campylobacter fetus subspecies jejuni. Campylobacter jejuni is a Gram-negative, slim, motile and curved rod as viewed through microscopy under a microscope such as monocular compound microscope. It is a microaerophilic organism, which implies that it needs reduced levels of oxygen. It is comparatively frail and sensitive to surrounding stresses like twenty-one percent oxygen, disinfectants, drying, acidic conditions and heating as observed by means of microscopy using a microscope like a monocular compound microscope. Due to its microaerophilic properties the organism needs three to five percent oxygen and two to ten percent carbon dioxide for maximum development conditions as monitored through microscopy under a monocular compound microscope. This bacterium is now an established vital enteric pathogen as examined by means of microscopy using a microscope such as monocular compound microscope. Prior to year 1972, when processes were created for its isolation from stools, it was deemed to be mainly an animal pathogen that triggers abortion and enteritis in sheep and cattle. Surveys have illustrated that Campylobacter jejuni is the main cause of bacterial diarrheal sickness in America. It initiates more illness than Shigella spp. and Salmonella spp. combined. (more…)

The Yersinia Enterocolitica and Yersinia Pseudotuberculosis

Yersinia enterocolitica is a small rod-shaped, Gram-negative bacterium as seen by means of microscopy using a microscope such as monocular compound microscope. It is frequently isolated from science clinical specimens like wounds, stools, sputum and mesenteric lymph nodes. Nevertheless, it is not a component of the normal human flora. Yersinia pseudotuberculosis has been detached from the diseased appendix of humans. Both organisms have frequently been isolated from animals like beavers, pigs, cats, birds, and dogs. Only Yersinia enterocolitica has been determined in ecological and food sources like lakes, ponds, milk, meats and ice creams. Majority of the isolates have been discovered not to be pathogenic as examined by means of microscopy under a microscope such as monocular compound microscope. The disease is known as Yersiniosis. There are three pathogenic species in the genus Yersinia, but only Yersinia enterocolitica and Yersinia pseudotuberculosis initiate gastroenteritis as examined through microscopy using a microscope like the monocular compound microscope. Up to now, no foodborne epidemics that are initiated by Yersinia pseudotuberculosis have been documented in America, but human contaminations carried through infected water and foods have been documented in Japan. Yersinia pestis, the causative agent of the plague is genetically incredibly alike to Yersinia pseudotuberculosis, as observed through microscopy using a microscope such as monocular compound microscope, but infects humans by routes other than food.

As seen through microscopy using a microscope such as monocular compound microscope, the Staphylococcus aureus is a spherical bacterium or coccus. When examined under the microscope like the monocular compound microscope, it appears in pairs, short chains, or bunched, grape-like groups. These organisms are Gram-positive as examined by means of microscopy under a microscope such as monocular compound microscope. Certain strains are capable of generating a highly heat-stable protein toxin that causes disease in humans. Staphylococcal food poisoning also known as staphyloenterotoxicosis or staphyloenterotoxemia is the terminology of the condition initiated by the enterotoxins that certain strains of Staphylococcus aureus generate.

The Salmonella

Salmonella is shaped like a rod and a motile bacterium as viewed through microscopy under a microscope such as monocular compound microscope. The non-motile exceptions are Salmonella gallinarum and Salmonella pullorum. They are not spore-forming and are Gram-negative as examined by means of microscopy using a microscope like the monocular compound microscope. There is a prevalent incidence in animals, specifically in poultry and swine. Ecological sources of the organism are water, land, factory and kitchen surfaces, insects, animal stools, uncooked or poorly cooked meats, and raw poultry and seafoods among others. (more…)

Clostridium botulinum is an anaerobic, Gram-positive, spore-forming rod as seen through microscopy using a microscope such as monocular compound microscope that generates a potent neurotoxin. The spores are heat defiant and can stay alive in foods that are improperly or minimally treated as observed by means of microscopy under a microscope like the monocular compound microscope. There are seven types of botulism, which are A, B, C, D, E, F and G that are acknowledged according to the antigenic specificity of the toxin generated by every strain as monitored through microscopy under a microscope such as monocular compound microscope. The types A, B, E and F trigger human botulism as examined by means of microscopy using a microscope like the monocular compound microscope. The types C and D initiate the major cases of botulism in animals. Animals that are greatly inflicted are wild fowl and poultry, horses, cattle and certain species of fish. Although type G has been isolated from soil in Argentina, no epidemics containing it have been known. (more…)
