1.1 - Staphylococcus aureus. CHAPTER 1 GRAM POSITIVE COCCI. Pre-Clinical USMLE Step 1 Course Sketchy Medical.
Microbiology is the branch of biology that focuses on the study of these microorganisms and their relationship to disease processes by describing their characteristics (e.g., species, structure, virulence factors, etc.). In the 19th century, Louis Pasteur introduced the germ theory of disease, which describes the relationship between microorganisms and illnesses. Concepts of contagion and its prevention slowly developed in different cultures over centuries. Infectious diseases have burdened humanity for millennia. This item is large, and may take some time to download. 1.3 - Streptococcus pyogenes (group A strep) 1.4 - Streptococcus agalactiae (group B strep) 1.5 - Streptococcus pneumoniae & viridans.sketchy micro for step 2ck.
There may also be headaches, dizziness, chills, and abdominal problems, such as nausea, vomiting, diarrhea, and abdominal pain. These symptoms are universal. Early symptoms include fatigue, fever and muscle aches, especially in the large muscle groupsthighs, hips, back, and sometimes shoulders.
After the advent of antibiotics, these diseases have become relatively less prevalent and less morbid than they used to be. It’s very contagious and is the most common cause of diarrhea in infants and young children worldwide.In the previous century, infectious diseases were the most significant causes of morbidity and mortality. What Is Rotavirus Rotavirus is a virus that causes diarrhea and other intestinal symptoms.
A majority of patients recover, but the illness can progress to severe encephalitis. Initial symptoms after the mosquito bite include fever, headache, and vomiting. The virus is maintained in a cycle between mosquitoes and avian hosts, but can spread to humans via bridge vectors (other species of mosquitoes).
Rotavirus Sketchy Micro Skin Surfaces Of
In the presence of certain environments or triggers, this fungus can cause pathologic diseases ranging from superficial skin conditions (tinea versicolor and dermatitis) to invasive disease (e.g., Malassezia folliculitis, catheter-associated fungemia, meningitis, and urinary tract infections). Prevention of mosquito bites is key in management.Malassezia is a lipophilic yeast commonly found on the skin surfaces of many animals, including humans. There is no specific treatment, and therapy is largely supportive.
Management entails the use of topical and oral antifungal agents.Orthopoxvirus is a genus of large, brick-shaped, double-stranded DNA viruses. The diagnosis of the superficial skin conditions is primarily by exam, but may be confirmed by microscopy of skin scrapings. The presentation of Malassezia folliculitis is similar to that of bacterial folliculitis, with pruritic, monomorphic papules or pustules in a follicular pattern. Seborrheic dermatitis presents with an erythematous, pruritic rash with greasy scales and yellow crust, most commonly affecting areas of the face, upper trunk, or intertriginous regions.
These infections are diagnosed with the aid of PCR, serology, viral culture, and/or electron microscopy. Vaccinia and cowpox produce milder disease with localized lesions acquired from direct skin-to-skin contact. Monkeypox presents similarly but has lower mortality and is associated with lymphadenopathy. Smallpox is associated with a high mortality rate. Smallpox is the most severe disease, presenting with constitutional symptoms and a diffuse, well-circumscribed maculopapular rash that progresses through an evolutionary process that results in scarring. Transmission varies depending on the species but can be through contact with infected bodily secretions, skin lesions, or fomites.
Although overlap exists, HSV-1 is classically associated with oropharyngeal lesions, whereas HSV-2 is mostly responsible for genital herpes, an STI. Typical mucocutaneous infections are characterized by an acute localized appearance of clusters of small, painful vesicles on an erythematous base. Herpes simplex virus commonly causes recurrent infections involving the skin and mucosal surfaces, including the mouth, lips, eyes, and genitals. Vaccination has led to the eradication of smallpox.Herpes simplex virus (HSV) is a double-stranded DNA virus belonging to the family Herpesviridae.
This course is amazing I still think COVID-19 needs to be studied a very profoundly in order to have more effective and efficient treatment for the patients who experience this dangerous COVID-19 diseaseEspecially I think post- COVID recovery’s very important as well.Many thanks for your great talk. That why is more interesting to study and memorable! I always love to study with differentials!As it is a new virus + with various subtypes ,I am taking my time to study rather just reading !I study to gain knowledge and skills not for a certificate Therefore I may take longer time And study all the details. September 2021 for CoronavirusYes this course is very complex and very interesting !!!!Especially pathogenesis part I think very important!!! As all treatment depends on it!I have taken so long to read those sessions as trying to compare from other sources if it had differences. The therapy for mucocutaneous lesions is usually symptomatic, but antiviral therapies involving acyclovir, valacyclovir, or famciclovir are useful if given early, and are always part of the therapy for serious systemic infections.By Gulbanu S. The diagnosis is made based on clinical presentation and history, which can be confirmed by the microscopic examination of a stained smear of a fresh vesicle, nucleic amplification test using PCR, direct immunofluorescence, or serologic tests.
Rotavirus Sketchy Micro Series A 4
If your a first or second year, this might not be the best choice for microbiology, however as a high yield review I would rank these microbiology videos second to none. High yield review source, 5 out of 5.So, overall, I would give this series a 4 out of 5. It is short, to the point, and highlights what you need to get most of those micro questions right on UWORLD and has the images in the slides that you need to be able to recognize.
