Pectobacterium carotovorum is a bacterium of the family Enterobacteriaceae; it formerly was a member of the genus Erwinia.

The species is a plant pathogen with a diverse host range, including many agriculturally and scientifically important plant species. It produces pectolytic enzymes that hydrolyze pectin between individual plant cells. This causes the cells to separate, a disease plant pathologists term bacterial soft rot. Specifically, it causes beet vascular necrosis and blackleg of potato and other vegetables (hence the name carotovora - "carrot-eater"), as well as slime flux on many different tree species.

This bacterius is a ubiquitous plant pathogen with a wide host range (carrot, potato, tomato, leafy greens, squash and other cucurbits, onion, green peppers, African violets etc.), able to cause disease in almost any plant tissue it invades. It is a very economically important pathogen in terms of postharvest losses, and a common cause of decay in stored fruits and vegetables. Decay caused by E. carotovora is often simply referred to as "bacterial soft rot" (BSR) though this may also be caused by other bacteria. Most plants or plant parts can resist invasion by the bacteria, unless some type of wound is present. High humidity and temperatures around 30°C favor development of decay. Mutants can be produced which are less virulent. Virulence factors include: pectinases, cellulases, (which degrade plant cell walls), and also proteases, lipases, xylanases and nucleases (along with the normal virulence factors for pathogens – Fe acquisition, LPS integrity, multiple global regulatory systems).

Botrytis cinerea ("botrytis" from Ancient Greek botrys (??????) meaning "grapes"[1] plus the Neolatin suffix -itis for disease) is a necrotrophic fungus that affects many plant species, although its most notable hosts may be wine grapes. In viticulture, it is commonly known as botrytis bunch rot; in horticulture, it is usually called grey mould or gray mold.

The fungus gives rise to two different kinds of infections on grapes. The first, grey rot, is the result of consistently wet or humid conditions, and typically results in the loss of the affected bunches. The second, noble rot, occurs when drier conditions follow wetter, and can result in distinctive sweet dessert wines, such as Sauternes or the Aszú of Tokaji/Gras? de Cotnari. The species name Botrytis cinerea is derived from the Latin for "grapes like ashes"; although poetic, the "grapes" refers to the bunching of the fungal spores on their conidiophores, and "ashes" just refers to the greyish colour of the spores en masse. The fungus is usually referred to by its anamorph (asexual form) name, because the sexual phase is rarely observed. The teleomorph (sexual form) is an ascomycete, Botryotinia fuckeliana, also known as Botryotinia cinerea (see taxonomy box).

Penicillium digitatum is a mesophilic fungus found in the soil of citrus-producing areas. It is a major source of post-harvest decay in fruits and is responsible for the widespread post-harvest disease in Citrus fruit known as green rot or mould. In nature, this necrotrophic wound pathogen grows in filaments and reproduces asexually through the production of conidiophores. However, P. digitatum can also be cultivated in the laboratory setting. Alongside its pathogenic life cycle, P. digitatum is also involved in other human, animal and plant interactions and is currently being used in the production of immunologically-based mycological detection assays for the food industry.

Bordetella pertussis is a Gram-negative, aerobic, pathogenic, encapsulated coccobacillus of the genus Bordetella, and the causative agent of pertussis or whooping cough. Unlike B. bronchiseptica, B. pertussis is not motile. Its virulence factors include pertussis toxin, filamentous hæmagglutinin, pertactin, fimbria, and tracheal cytotoxin.

A zoonotic reservoir for B. pertussis does not appear to exist; humans are its only known host (similar to the case of the polio virus). This means universal vaccination could potentially eradicate the disease.

The bacterium is spread by airborne droplets; its incubation period is 7 to 14 days.

Taylorella equigenitalis is a Gram-negative bacterium of the genus Taylorella, and the causative agent of contagious equine metritis (CEM) in horses.

Infected stallions are asymptomatic and act as the principal source of infection as they mate with numerous mares, and the carrier status may persist for many months or even years.

Burkholderia pseudomallei (also known as Pseudomonas pseudomallei) is a Gram-negative, bipolar, aerobic, motile rod-shaped bacterium. It infects humans and animals and causes the disease melioidosis. It is also capable of infecting plants.

B. pseudomallei measures 2–5 ?m in length and 0.4–0.8 ?m in diameter and is capable of self-propulsion using flagellae. The bacteria can grow in a number of artificial nutrient environments, especially betaine- and arginine-containing ones.

In vitro, optimal proliferation temperature is reported around 40 °C in neutral or slightly acidic environments (pH 6.8–7.0). The majority of strains are capable of fermentation of sugars without gas formation (most importantly, glucose and galactose, older cultures are reported to also metabolize maltose and starch). Bacteria produce both exo- and endotoxins. The role of the toxins identified in the process of melioidosis symptom development has not been fully elucidated.

Sphaerotilus natans is an aquatic periphyton organism associated with polluted water. It forms colonies commonly known as "sewage fungus", but later identified as tightly sheathed filamentous bacteria.

Sphaerotilus natans is often associated with a buoyant floc (or "bulking sludge") causing poor solids separation in activated sludge clarifiers of secondary sewage treatment.[4] Metal surfaces covered with S. natans may experience accelerated corrosion if the slime creates a barrier causing differential oxygen concentrations.[6] S. natans slimes may reduce quality of paper produced by paper mills using recycled water streams.

Comamonas composti is a aerobic, gram-negative, rod-shaped, non-spore-forming, weak oxidase-positiv, catalase-positiv, motile bacterium from the genus of Comamonas and the family of Comamonadaceae which was isolated from food waste compost.

Lautropia mirabilis is a Gram-negative, facultatively anaerobic, oxidase- and catalase-positive, motile bacterium of the genus Lautropia and family Burkholderiaceae, isolated from the mouth of children who were infected with human immunodeficiency virus.
