Name of Organism Colony Morphology
(Front and Reverse) Microscopic Morphology Type of Infections Caused
Pathogenicity Growth Rate Additional Info
(Example) Front: fluffy gray-white
‘lid lifter’ Conidiophore with rhizoids at base and sporangium filled with spores at apex
Wide, ‘ribbon-like’ hyphae Invasive sinus
Can be fatal Fast
Mucor Front: fluffy, White and gray with age.
“ lid lifter” Resemble to Rhizopus in Sporaniphore and sporangium and the differ by rhizoids mucormycosis Very fast
Absidia Front: fluffy, at the first white and pale gray with age
“Lid lifter” Between the sporangiophores we see the originated Rhizoids Zygomycosis Fast
Lichtheimia Front: fluffy, white- gray or…
aureus is a gram-positive bacterium, which is a facultative anaerobe. It colonizes the skin, nostrils, and/or perineum (Thomer et al., 2015). This bacterium is an opportunistic pathogen that causes both short and long term illnesses after it invades the host. Some of these illnesses are bacteremia, toxic shock syndrome, sepsis, and endocarditis (Wang & Muir, 2016).
Approximately one-third of the human population is colonized by S. aureus, and another one-third is intermittently colonized with…
1.1. Serratia Marcescens
Serratia marcescens is a motile, rod-shaped, gram-negative anaerobic bacillus, that is a member of the genus Serratia, which belongs to the Enterobacteriaceae family. It has become an important opportunistic pathogen associated with a number of life-threatening diseases and nosocomial infections (Hejazi and Falkiner, 1997). S. marcescens is known to have high survival capability under hostile conditions; it is commonly found in a number of disinfectants…
aeruginosa is frequently found in the hospital environment and in the normal stool flora, it is difficult to trace the source of infection and/or colonization unless a complete study is undertaken.(Teplitz et al., 1964). The epidemiology of hospital infections due to Pseudomonas aeruginosa was investigated by pyocin typing. The typing method, which determined the pyocin activity of clinical isolates of P. aeruginosa on 27 indicator strains, was 43.7% reproducible, but elimination of 9 indicator…
pertussis gets into the respiratory tract, it attaches itself to the cilia of the epithelial cells of the respiratory tract. After doing this, the microbes release toxins that immobilize the cilia of the epithelial cells.
One of the more understood pertussis toxins is called the lymphocytosis-promoting factor which is responsible for causing a decrease in the amount of neutrophils to the lungs making them susceptible to other bacterial infetions. It also leads to the inflammation of the…
Pneumocystis pneumonia represents a potentially life-threatening infection caused by a fungal microorganism Pneumocystis jiroveci. Initially observed in premature and malnourished infants, Pneumocystis pneumonia is today one of the most frequent opportunistic infections in adults infected with human immunodeficiency virus (HIV).
As nonspecific symptoms are often hindering timely diagnosis, one of the most important diagnostic tools for Pneumocystis pneumonia is a high level of clinical…
russelii), Saw-scaled viper (Echis carinatus), and common krait (Bungarus caeruleus) are most deadly. The majority of snakebites encountered by these snakes therefore called India’s Big 4. Bites of snakes are usually fatal, the survived victims always on the risk of secondary infection arises from snakebite. Additional to envenomation complication of wound infection and soft tissue necrosis fasciitis, however, snakebite wounds polymicrobial…
This can occur when hands contaminated with the bacterium are not cleaned properly and exposed to individuals, for example in a hospital, a nurse handling a patient with Klebsiella Pneumonia infection and then coming into contact with another patient whilst having the bacterium on them. Although the bacterium enters through the respiratory tract, Klebsiella Pneumonia does not transmit through air.
The opportunistic pathogen is more likely to affect elderly individuals with weakened immune…
facultative anaerobic gram negative bacilli. Their means of motility is by means of petrichous flagella. They produce acid upon glucose fermentation and are methyl red negative, voges-proskauer positive. Optimal growth temperature is 30*C .80% are encapsulated.
E. spp have been associated with nosocomial outbreak and are opportunistic pathogens. They can cause numerous infections such as cerebral abscess, pneumonia, meningitis, septicemia, some certain UTI infections. In addition, they have…
