''Burkholderia mallei'' is a Gram-negative, bipolar, aerobic, non-motile bacterium that does not produce spores. It is a small, rod-shaped bacterium that develops slowly in most culture conditions and is a facultative intracellular pathogen. This host-adapted bacterium may survive in the environment for a brief time and is responsible for glanders, a zoonotic illness that mostly affects horse populations and other animals but is rare in humans.[1] ''B. mallei'' is closely related to ''B. pseudomallei'', and genetic studies indicate that it arose as a subspecies of ''B. pseudomallei'' via selective reduction and deletions from the ''B. pseudomallei'' genome, most likely adapting to an intracellular lifestyle within animal hosts.[2] ''B. mallei'', unlike ''B. pseudomallei'' and other members of the genus, is non-motile and has a coccobacillary shape, measuring 1.5-3.0 μm in length, 0.5-1.0 μm in diameter, and rounded ends. | ''Burkholderia mallei'' is a Gram-negative, bipolar, aerobic, non-motile bacterium that does not produce spores.

The Centers for Disease Control and Prevention (CDC) classifies ''B. mallei'' as a category B select agent due to its high infectiousness, potential for biological warfare and bioterrorism, and hazard to public health and agriculture.[3] The development of improved diagnostic tools, vaccines, and therapeutic strategies for this pathogen is important. ''B. mallei'' was one of the earliest biological warfare agents utilized in the nineteenth century, particularly during World War I, when German agents purposely infected horses and livestock in the United States, Spain, Norway, and other nations via inoculation and feed contamination.[4] While ''B. mallei'' cannot survive outside of its host, thus restricting its utility as a bioweapon, other countries, such as Japan and Russia, have investigated it as a potential biological weapon. Despite its inability to survive outside of a host, ''B. mallei'''s high infectivity and potential for serious harm to human and animal populations make it a troubling virus that necessitates continued research and preparedness measures.[5] | The Centers for Disease Control and Prevention (CDC) classifies ''B. mallei'' as a category B select agent due to its high infectiousness, potential for biological warfare and bioterrorism, and hazard to public health and agriculture.[3] The development of improved diagnostic tools, vaccines, and therapeutic strategies for this pathogen is important.

''B. mallei'' cells are typically coccobacilli shaped, measuring in a range of 1.5–3.0 μm in length and 0.5–1.0 μm in diameter with rounded ends [3] . What separates ''B. mallei'' from its motile counterpart ''B. pseudomallei'' , ''B. mallei'' is nonmotile meaning its not capable of movement on its own. As discussed earlier the cell wall of ''B. mallei'' is Gram-negative, with an outer membrane containing lipopolysaccharides that contribute larg;y to its interaction with host cells. ''B. mallei'' usually produces a thick capsule made up of polysaccharides which are used as a virulence factor protecting the bacteria from host immune defenses [2].

Description and Significance
Burkholderia mallei is a Gram-negative, bipolar, aerobic, non-motile bacterium that does not produce spores. It is a small, rod-shaped bacterium that develops slowly in most culture conditions and is a facultative intracellular pathogen. This host-adapted bacterium may survive in the environment for a brief time and is responsible for glanders, a zoonotic illness that mostly affects horse populations and other animals but is rare in humans.[1] B. mallei is closely related to B. pseudomallei, and genetic studies indicate that it arose as a subspecies of B. pseudomallei via selective reduction and deletions from the B. pseudomallei genome, most likely adapting to an intracellular lifestyle within animal hosts.[2] B. mallei, unlike B. pseudomallei and other members of the genus, is non-motile and has a coccobacillary shape, measuring 1.5-3.0 μm in length, 0.5-1.0 μm in diameter, and rounded ends.
The Centers for Disease Control and Prevention (CDC) classifies B. mallei as a category B select agent due to its high infectiousness, potential for biological warfare and bioterrorism, and hazard to public health and agriculture.[3] The development of improved diagnostic tools, vaccines, and therapeutic strategies for this pathogen is important. B. mallei was one of the earliest biological warfare agents utilized in the nineteenth century, particularly during World War I, when German agents purposely infected horses and livestock in the United States, Spain, Norway, and other nations via inoculation and feed contamination.[4]While B. mallei cannot survive outside of its host, thus restricting its utility as a bioweapon, other countries, such as Japan and Russia, have investigated it as a potential biological weapon. Despite its inability to survive outside of a host, B. mallei's high infectivity and potential for serious harm to human and animal populations make it a troubling virus that necessitates continued research and preparedness measures.[5]
Genome Structure
B. mallei's genome exhibits distinctive features that separate it from other members of the Burkholderia genus. Unlike its closely related counterpart, B. pseudomallei which has a larger genome (around 7.3 Mb) size, B. mallei has a smaller genome with unique characteristics (around 3.5 mb) [1]. While B. pseudomallei has a larger genome size, Burkholderia mallei's genome is relatively smaller overall. Which can reflect selective reduction and deletions from the B. pseudomallei genome during its evolution into a specialized and uniquely distinct pathogen. B. mallei's genome provides insights into its phylogenetic relationship with other members of the Burkholderias genus and related organisms. Multilocus sequence typing has classified Burkholderia mallei as a subspecies of B. pseudomallei which is suspected to come from clone reduction [4]. This can indicate a close evolutionary relationship [7]. However, genomic analysis reveals that there are distinct genetic differences between the two species, reflecting that their differences in ecological niches and lifestyles as pathogens. Overall the genome is structured as being made up of two circular chromosomes each with their own designated roles. Chromosome one harbors genes for basic cellular functions while chromosome two contains genes associated with adaptation, virulence and pathogenicity[2] . Understanding th genome structure of B. Mallei is crucial for observing its pathogenic mechanisms, evolutionary history and adaptation to its host environment. This is possible from comparative genomic analysis which provides strategies for diagnosis, treatment and prevention of infections caused by the pathogens [2].
