B. pseudomallei can be differentiated from another closely related, but less pathogenic species B. thailandensis by its ability to assimilate arabinose. B. pseudomallei is highly adaptable to various host environments ranging from inside mycorrhizal fungi spores to amoeba. Its adaptability may give it a survival advantage in the human body.The genome of B. pseudomallei consists of two replicons: chromosome 1 encodes housekeeping functions of the bacteria such as cell wall synthesis, mobility, and metabolism; chromosome 2 encodes functions that allow the bacteria to adapt to various environments. Horizontal gene transfer has resulted in highly variable genomes in B. pseudomallei. Australia has been suggested as the origin for B. pseudomallei because of the high genetic variability of the bacteria found in this region. Bacteria that was introduced to Central and South America in the 17th to 19th centuries seem to have a common ancestor from Africa. B. mallei is a clone of B. pseudomallei that has lost substantial portions of its genome as it adapted to live exclusively in mammals. This makes the B. mallei genome much smaller than B. pseudomallei. Transmission
B. pseudomallei is normally found in soil and surface water, and is most abundant at soil depths of 10 to 90 cm. It has been found in soils, ponds, streams, pools, stagnant water, and rice paddy fields. B. pseudomallei can survive in nutrient-poor conditions such as distilled water, desert soil, and nutrient-depleted soil for more than 16 years.
The anatomy of the domestic cat is similar to that of other members of the genus Felis. Mouth
Permanent dentition teeth
Cats are carnivores that have highly specialized teeth. There are four types of permanent dentition teeth that structure the mouth: twelve incisors, four canines, ten premolars and four molars. The premolar and first molar are located on each side of the mouth that together are called the carnassial pair. The carnassial pair specialize in cutting food and are parallel to the jaw. The incisors located in the front section of the lower and upper mouth are small, narrow, and have a single root. They are used for grasping and biting food. Deciduous dentition teeth
A cat also has a deciduous dentition prior to the formation of the permanent one. This dentition emerges seven days after birth and it is composed of 26 teeth with slight differences. The mouth will have smaller incisors, slender and strongly curved upper canines, vertical lower canines, and even smaller upper and lower molars. Although the upper and lower molars are smaller than the ones that arise during permanent dentition, the similarities are striking. Tongue
The cats tongue is covered in a mucous membrane and the dorsal aspect has 5 types of sharp spines, or papillae. The 5 papillae are filiform, fungiform, foliate, vallate, and conical. A cats sense of smell and taste work closely together, having a vomeronasal organ that allows them to use their tongue as scent tasters, while its longitudinal, transverse, and vertical intrinsic muscles aid in movement.
