CAUSES OF STAPHYLOCOCCUS

these are causes of staff thruogh food poison and bacterials aureus, I hope you learn from this lecture...

METHICILLIN-RESISTANT STAPHYLOCOCCUS AUREUS INFECTION
These are facilities through an infected or colonized patient or a colonized health care worker. Although MRSA has been recovered from environmental surfaces, it's transmitted mainly by health care workers’ hands. Many colonized individuals become silent carriers. The most frequent site of colonization is the anterior nares (40% of adults and most children become transient nasal carriers). Other, less common sites are the groin, axilla, and the gut. Typically, MRSA colonization is diagnosed by isolating bacteria from nasal secretions.

In individuals where the natural defense system breaks down, such as after an invasive procedure, trauma, or chemotherapy, the normally benign bacteria can invade tissue, proliferate, and cause infection. Today, up to 90% of S. aureus isolates or strains are penicillin resistant, and about 50% of all S. aureus isolates are resistant to methicillin, a penicillin derivative, as well as to nafcillin and oxacillin. These strains may also resist cephalosporins, aminoglycosides, erythromycin, tetracycline, and clindamycin.
MRSA infection has become prevalent with the overuse of antibiotics. Over the years, this has given once-susceptible bacteria the chance to develop defenses against antibiotics. This new capability allows resistant strains to flourish when antibiotics kill their more-sensitive cousins

STAPHYLOCOCAL SCALDED SKIN SYNDROME
The causative organism in SSSS is group 2 Staphylococcus aureus, primarily phage type 71, which produces exotoxins that cause detachment of the epidermis. Predisposing factors may include impaired immunity and renal insufficiency — present to some extent in the normal neonate because of immature development of these systems. SSSS is most prevalent in infants age 1 to 3 months but may develop in children. It’s uncommon in adults.

VANCOMYCIN INTERMEDIATELY RESISTANT STAPHYLOCOCCUS AUREUS
Vancomycin-resistant enterococcus (VRE) and MRSA enter health care facilities through an infected or colonized patient or a colonized health care worker. It’s thought that VISA and VRSA are colonized in a similar method. They’re spread through direct contact between the patient and caregiver or between patients. They may also be spread through patient contact with contaminated surfaces such as an overbed table. They’re capable of living for weeks on surfaces. They’ve been detected on patient gowns, bed linens, and handrails.

BOTULISM
Botulism is usually the result of ingesting inadequately cooked contaminated foods, especially those with low acid content, such as home-canned fruits and vegetables, sausages, and smoked or preserved fish or meat. Honey and corn syrup may contain C. botulinum spores and shouldn’t be fed to infants. Rarely, botulism results from wound infection with C. botulinum.
Botulism occurs worldwide and affects more adults than children. Recently, findings have shown that an infant’s GI tract can become colonized with C. botulinum from some unknown source, and then the exotoxin is produced within the infant’s intestine. Incidence had been declining, but the current trend toward home canning has resulted in an upswing in recent years. Wound botulism occurs when open areas are infected with C. botulinum that secretes the toxin.

CAMPYLOBACTERIOSIS
Campylobacteriosis is an intestinal infection caused by the Campylobacter organism, a spiral-shaped bacteria that invades and destroys the epithelial cells of the jejunum, ileum, and colon. It may spread to the bloodstream in persons with compromised immune systems, causing a life-threatening infection
Campylobacteriosis is transmitted by the consumption of contaminated food, such as raw poultry, fresh produce, water, or unpasteurized milk; and through contact with an infected person's stool. Transmission is also possible through contact with infected pets and wild animals. Risk factors include recent family infection with C. jejuni and travel to an area with poor hygiene or sanitation practices. Campylobacteriosis, which is more common in the summer months, is the most common bacterial cause of diarrheal illness in the United States.

ESCHERICHIA COLI AND OTHER ENTEROBACTERIACEAE INFECTIONS
Although some strains of E. coli exist as part of the normal GI flora, infection usually results from certain nonindigenous strains. For example, noninvasive diarrhea results from two toxins produced by strains called enterotoxic or enteropathogenic E. coli. Enteropathogenic E. coli serotype 0157:H7 is the most well-known strain in the society. These toxins interact with intestinal juices and promote excessive loss of chloride and water. In the invasive form, E. coli directly invades the intestinal mucosa without producing enterotoxins, thereby causing local irritation, inflammation, and diarrhea. Normal strains can cause infection in immunocompromised patients.
Transmission can occur directly from an infected person or indirectly by ingestion of contaminated food or water or contact with contaminated utensils. Incubation takes 12 to 72 hours.
Incidence of E. coli infection is highest among travelers returning from other countries, particularly Mexico, Southeast Asia, and South America. E. coli infection also induces other diseases, especially in people whose resistance is low. The strain E. coli 0157:H7 has been associated with undercooked hamburger and with animals and petting zoos.

These and other causes which u can confirm from your doctor, are dangerous, pls your health is ur wealth.
