🥹 Bacteriology - Introduction to the study of Pathogens

Disease

What do you call the alteration or deviation of the normal state of the body that disturbs or interrupts the proper performance of physiological functions?

External

What cause of disease is chemical poisons?

Disease

What is the effect of Neoplasms on the body — disease or infection?

Living agent

What enters the body that sets a disturbance in body functions?

Infected feeding troughs and dried discharges

Where can fomites be seen?

Infection

What is the effect of disease carriers — infection or disease?

Nosocomial infections

What do you call infections acquired through confinement of an animal during hospitalization?

Portals of entry

What do you call the routes where pathogens enter the body and initiate infection?

True

Infection can come from the genitals — true or false?

No

Destruction of the pathogen by the vector’s tissues — is it one of the fates of infecting pathogens?

Impasse

What do you call the concept where the pathogen can not invade the host?

Yes

Is IgA proteases considered a virulence factor?

enhance microbial virulence

What does hyaluronidase do?

gene-controlled

Iron penetration — gene-controlled or plasmid-controlled virulence?

gene-controlled

Colisin production — gene-controlled or plasmid-controlled virulence?

plasmid-controlled

K88 of E.coli — gene-controlled or plasmid-controlled virulence?

plasmid-controlled

Enteroinvasive ability — gene-controlled or plasmid-controlled virulence?

Yes

Is penetration of hosts surfaces an element for the production of infection?

No

Is microbial growth in pathogens an element for the production of infection?

Mycoplasma gallisepticum

What strain of disease where its pathogens attach to the bronchial epithelium of chickens?

Adherence to epithelial cells in mammary glands

How does staphylococcus aureus manifest in cows?

Afimbrial surface proteins

Bacterial adhesin of Streptococci sp.

P-1

Bacterial adhesin of Mycoplasma pneumonia

Mannose

Host receptors of E. coli

Fibronectin

Host receptors of Streptococci and Staphylococci

No

Are inorganic acids inhbitors of bacterial attachment?

Yes

Are lysozymes inhbitors of bacterial attachment?

Microbial growth in tissues

This is a concept of neutralization of host defenses and pathogen.

Destruction of vascular supply of tissues

What adaptations from the microbial growth in tissues that affect vascular supply of tissues?

Damages alveolar macrophages and polymorphonuclear leukocytes

What does cytotoxin do?

Salmonella spp.

What bacteria has the O-polysaccharide structure?

Iron capture

What component of E. coli enhances bacterial growth?

Blood

Where does the tetanospamin as a potent toxin in the body circulate?

Lecithinase and phospholipids

What bacteria component releases bacterial enzymes and damages cell body components?

False

Hypertension is a biological effect of endotoxin.

Yes

Neutropenia and thrombocytopenia is a biological effect of endotoxin.

PMN lytic enzymes

What enzymes are involve in the engulfment and lysis of pathogens?

endogenous pyrogens

During fever, what does the neutrophils release?

IgM

What marks an antibody response — increase levels of IgG or IgM?

Tonsils

Where does the antibody production as a local immune response be seen?

Aerobic gram negative cocci

What is the bacterial classification of Neisseria?

Aerobic gram positive cocci

What is the bacterial classification of Staphylococcus?

Aerobic gram negative rods

What is the bacterial classification of Serratia?

Aerobic gram positive rods

What is the bacterial classification of Corynebacterium?

Anaerobic gram negative non-sporeforming rods

What is the bacterial classification of Actinomyces?
