Coxiella burnetti – trachoma

Choose cell-wall deficient bacterium, resistant to beta-lactams:

Choose correct combination of drugs of choice recommended to treat bacterial meningitis:

1 month– 5-year-old children – ampicillin and gentamicin

Adults– ampicillin and metronidazole

Newborns – ampicillin and cefotaxime

10-18-year-old – gentamicin and cefazolin

Isoniazid for meningococcal prophylaxis of high-risk groups

Diagnosis: renal tuberculosis. Which of the laboratory test is the most appropriate to confirm the etiology?

Which of the following bacteria are associated with pyelonephritis and kidney stone formation?

Ureaplasma urealyticum, Pseudomonas aeruginosa

Pseudomonas aeruginosa, Acinetobacter baumanii

Acinetobacter baumanii, Kingella kingae

Proteus mirabilis, Klebsiella pneumoniae

Staphylococcus saprophyticus, Chlamydia trachomatis

Choose bacterium most commonly associated with periodontitis in adults:

Which of the following viruses binds to CR2 (CD21) receptor of complement C3d component:

RSV:

Causes localized infection of the respiratory tract

Causes viremia and systemic spread

Natural infection prevents reinfection

Cytopathic effect includes syncytia formation

Maternal antibody does not prevent infant from infection

Choose the most common etiological agents of atypical pneumonia in school-age children (5-15 years old):

RSV, Haemophilus influenzae

Adenoviruses, Streptococcus pneumoniae

Moraxella catarrhalis, Pneumocystis jiroveci

Chlamydophila pneumoniae, Mycoplasma pneumoniae

Streptococcus pneumoniae, Influenza virus

Invasive aspergillosis:

Indicates patients with complement deficiencies

Is associated with neutropenia and impaired function of phagocytic cells

Voriconazole and amphotericin B are recommended for treatment

Is most commonly caused by Aspergillus fumigatus

Respiratory tract is the main and most important gate of entry

Roxithromycin:

Is an option used to treat infections caused by Chlamydophila pneumoniae

Is bacteriostatic

Due to its spectrum is the first-line drug used to treat UTI

Inhibits bacterial DNA synthesis

Is active against I.a. Gram-positive cocci

Bacterial resistance to quinolones stems from:

Choose the correct statement regarding human microbiota:

Core microbiome are microbial species that contribute to the unique diversity of individuals at specific body sites

Probiotics are food ingredients that support the growth of one or more members of the microbiota

Secondary microbiome is represented by a limited number of species, which comprise the largest proportion of the microbial population

Of the approximately 200 unique species of bacteria that colonize the gut, most are members of Actinobacteria, Bacteroidetes, and Firmicutes

Use of broad-spectrum antibiotics doesn't lead to the disruption of the microbiome and loss of essential functions

Choose the correct combination:

Strictly anaerobic, Gram-negative rods – Chlamydia

Strictly anaerobic, Gram-negative rods – Bacteroides

Facultatively anaerobic, Gram-negative cocci – Enterococcus

Strictly anaerobic, Gram-positive spore-forming rods – Actinomyces

Strictly aerobic, Gram-negative rods – Helicobacter

Choose assays, which due to low sensitivity are not useful in the diagnosis of Mycoplasma pneumoniae infections:

Choose virulence factors of Neisseria meningitidis:

Fimbriae – mediate attachment to human cells

Opa protein– membrane proteins that mediate binding to epithelial cells

Leukocidin – leukocyte damage

IgA1 protease– destroys immunoglobulin A1

Polypeptide capsule – antiphagocytic properties

Choose agent/s used in HIV therapy:

Azidothymidine–nucleoside analogue reverse transcriptase inhibitor

Saquinavir – transcriptase inhibitor

Zanamivir– CCR5 co-receptor antagonist

Nevirapine – protease inhibitor

Enfuvirtide– protein synthesis inhibitor

Foodborne disease associated with Yersinia enterocolitica may follow the ingestion of:

The following are examples of drug synergism except:

Vancomycin and gentamicin – Enterococcus infections

Ceftazidime I gentamicin – P. Aeruginosa infections

Trimethoprim and vancomycin – E. Coli infections

Amphotericin B and flucytosine – cryptococcal meningitis

Ampicillin and gentamicin – Listeria meningitis

Choose incorrect statement regarding the diagnostic of viral infections:

Syncytia are formed in cells infected with RSV

Seroconversion is at least a fourfold increase of IgG titer in patient serum

Clinical specimen is transported at room temperature, collected on special artificial media

SARS-CoV2 genetic material is detected in nasopharyngeal swabs using Real-Time PCR

Real-Time PCR is used for the quantitative determination of HIV in patient serum

Choose bacterial agents primarily responsible for ostitis:

Campylobacter jeikeum

Treponema pallidum, Staphylococcus hominis

Haemophilus parainfluenzae, Vibrio parahaemolyticus

Prevotella melaninogenica, Mycoplasma spp

Staphylococcus aureus, Pseudomonas aeruginosa

Potentially non-oncogenic DNA virus

Potentially non-oncogenic RNA virus

Potentially oncogenic RNA virus

Potentially oncogenic DNA virus

RNA defective virus

Choose the correct statement regarding viruses:

The envelope is composed of lipids, proteins, and glycoproteins

Naked capsid is non-infective after drying

Are obligate extracellular parasites

Enveloped viruses are resistant to detergents and heat

Can make energy and proteins independently of a host cell

A 16-year-old male patient has had a sore throat, swollen cervical lymph nodes, fever, increasing fatigue, and hepatosplenomegaly. Laboratory examination of blood samples revealed the presence of atypical lymphocytes and heterophile antibodies. After ampicillin was introduced into the treatment, a skin rash has appeared. The clinical picture described most probably indicates an infection caused by:
