“…thailandensis are avirulent or of low pathogenicity, while other species such as B. glumae and B. gladioli only cause disease in plants and rice (Brett et al., ; Nandakumar and Rush, ). Other species of Burkholderia can be pathogens in humans and animals such as B. cepacia causing ‘cepacia syndrome’ in cystic fibrosis patients or B. mallei and B. pseudomallei which cause glanders and melioidosis, respectively (Stoyanova et al., ). Melioidosis is a fatal disease in both humans and animals.…”

Melioidosis is caused by Burkholderia pseudomallei and is an important zoonotic infectious disease causing high mortality from fulminant septicaemia in humans and a wide variety of animal species. The incidence of fatal melioidosis in zoo animals has been significant in many Thai zoos. A total number of 32 cases were evaluated throughout the Thai zoo animal populations. The highest prevalence of disease has been reported from the north-eastern region followed by the zoos in the southern part of the country, approximately 47% and 38%, respectively, while the other zoos reported sporadic infections. Herbivores and non-human primates were the most commonly affected animals with incidences of 59% and 28%, respectively. This appears to be a seasonal correlation with the highest incidence of melioidosis in zoo animals reported in the rainy season (44%) or subdivided monthly in June (19%) followed by September and November (16% and 12%, respectively). The route of infection and the incubation period still remain unclear. This retrospective study examined the clinical presentation in various zoo species, pathological findings and epidemiological data as well as conducting an in depth literature review.

“…Utilisation of a wide range of organic compounds as carbon and energy sources is characteristic of all burkholderias (Belova et al, 2006). The genus Burkholderia includes various microorganisms that occupy a wide range of ecological niches, such as soil, water, rhizosphere and tissues of plants, and animal and human hosts (Stoyanova et al, 2007). The members of the genus have very different ecological and pathological behaviour, from saprophytic activity to plant growth-promoting features (Shaharoona et al, 2007); several species are causal agents of plant, animal and human diseases.…”

The EFSA Panel on Plant Health conducted a pest risk assessment for Burkholderia caryophylli for the EU territory under the scenario of current EU legislation and identified and evaluated risk reduction options. B. caryophylli is absent from the EU territory. The host range of B. caryophylli includes the genus Dianthus and three other incidental, minor, hosts (statice, lisianthus and gypsophila). Seven entry pathways were identified, with carnation cuttings and cut flowers being the most frequently traded. All pathways were considered unlikely as the pathogen is rarely associated with the pathways at origin mostly because of the high phytosanitary quality of the plant propagation material. The establishment is unlikely because outdoors the environmental conditions are not favourable to the pathogen and alternative hosts are not present, whereas in protected crops the cultural practices are very effective to keep the crop free from this bacterium. Only very short‐distance spread within a crop is likely, and spread between different crops is unlikely. Risk reduction options addressing the sanitary status of the propagation material have the best effectiveness and feasibility. Effective control measures are based on healthy propagation materials (cuttings) and hygiene practices. With the existing certification scheme of carnation plant propagation material, the probability of spread through infected cuttings is largely reduced. The high effectiveness of current measures is ensured by the absence of B. caryophylli in the EU, as in recent decades no findings of B. caryophylli have been reported.B. caryophylli is reported to be present in some third countries in Asia, where it still causes high crop losses. If the current regulation were to be removed, major consequences or changes in the potential impact of B. caryophylli are expected if no voluntary certification scheme were applied, together with good sanitation standards, along the crop production chain.

“…Burkholderia cenocepacia is the causal agent of fingertip rot disease in banana and bacterial rot in onion bulbs (Sotokawa and Takikawa 2004). Burkholderia gladioli also causes leaf-sheath browning in both gladiolas and onions (Stoyanova et al 2007). Additionally, B. glumae is a representative phytopathogen that causes bacterial panicle blight, seedling sheath rot, and grain discoloration in rice and various field crops, including pepper, tomato, and eggplant (Jeong et al 2003).…”

Understanding the direction of evolution in Burkholderia glumae through comparative genomics

et al. 2015

Members of the genus Burkholderia occupy remarkably diverse niches, with genome sizes ranging from ~3.75 to 11.29 Mbp. The genome of Burkholderia glumae ranges in size from ~5.81 to 7.89 Mbp. Unlike other plant pathogenic bacteria, B. glumae can infect a wide range of monocot and dicot plants. Comparative genome analysis of B. glumae strains can provide insight into genome variation as well as differential features of whole metabolism or pathways between multiple strains of B. glumae infecting the same host. Comparative analysis of complete genomes among B. glumae BGR1, B. glumae LMG 2196, and B. glumae PG1 revealed the largest departmentalization of genes onto separate replicons in B. glumae BGR1 and considerable downsizing of the genome in B. glumae LMG 2196. In addition, the presence of large-scale evolutionary events such as rearrangement and inversion and the development of highly specialized systems were found to be related to virulence-associated features in the three B. glumae strains. This connection may explain why this bacterium broadens its host range and reinforces its interaction with hosts.
