“…During their stay in the desert they can easily have contact with excretions of desert gazelles, from which this case may have contracted the infection. Several authors have reported tuberculosis in gazelles of the Arabian Peninsula Greth et al, 1994;Ostrowski et al, 1998). It is also worthy of mention that dromedaries are coprophagous animals.…”

An adult male dromedary bull was diagnosed with pulmonary tuberculosis (Tb). The dromedary was severely emaciated and died 2 months after the onset of the disease. It exhibited typical Tb lesions in both lungs and lung lymph nodes. A guinea pig inoculated with lung tissue from theTb camel died after 3 weeks from typical Tb. Mycobacteria were isolated from the dromedary's lung and lung lymph nodes and also from different organs of the guinea pig. The microorganism was identified as member of the antelope clade of the Mycobacterium tuberculosis complex.

We investigated the causes of mortality of the Arabian gazelle (Gazella arabica) based on the necropsy records of 1218 captive animals at King Khalid Wildlife Research Centre, Saudi Arabia, from 1988 to 2011. The largest number of deaths was attributed to trauma (391, 32.1%). Trauma was subdivided into the following three categories: collisions with fences (144, 11.8%); predator activity (91, 7.5%), and exhibit-mate aggression (156, 12.8%). Respiratory infection was another important cause of mortality, accounting for 186 (15.3%) deaths. Respiratory infection was more prevalent during the winter season (November to March). Other causes of death included gastrointestinal diseases, such as clostridiosis and salmonellosis (108, 8.9%). Maternal neglect (104, 8.5%), chronic renal fibrosis (34, 2.8%), and stress-related pathologies (35, 2.9%), in particular, capture myopathy, were also important causes of mortality. Here, the importance of these findings for improvement of the captive management of this vulnerable Arabian species is discussed, and for the first time, salmonellosis in Arabian gazelles is reported.

“…TB in oryxes (Oryx leucoryx; an antelope species) has previously been reported (28,47,84), but to date the oryx bacillus has been but mentioned in passing as a phenotypically divergent subtype of M. bovis (7,42,84). The two isolates evaluated in this study were retrieved from oryxes in a wild park in Saudi Arabia and a zoo in The Netherlands.…”

Novel Genetic Polymorphisms That Further Delineate the Phylogeny of the Mycobacterium tuberculosis Complex

In a previous report, we described a PCR protocol for the differentiation of the various species of the Mycobacterium tuberculosis complex (MTC) on the basis of genomic deletions (R. C. Huard, L. C. de Oliveira Lazzarini, W. R. Butler, D. van Soolingen, and J. L. Ho, J. Clin. Microbiol. 41:1637-1650, 2003). That report also provided a broad cross-comparison of several previously identified, phylogenetically relevant, longsequence and single-nucleotide polymorphisms (LSPs and SNPs, respectively). In the present companion report, we expand upon the previous work (i) by continuing the evaluation of known MTC phylogenetic markers in a larger collection of tubercle bacilli (n ‫؍‬ 125), (ii) by evaluating additional recently reported MTC species-specific and interspecific polymorphisms, and (iii) by describing the identification and distribution of a number of novel LSPs and SNPs. Notably, new genomic deletions were found in various Mycobacterium tuberculosis strains, new species-specific SNPs were identified for "Mycobacterium canettii," Mycobacterium microti, and Mycobacterium pinnipedii, and, for the first time, intraspecific single-nucleotide DNA differences were discovered for the dassie bacillus, the oryx bacillus, and the two Mycobacterium africanum subtype I variants. Surprisingly, coincident polymorphisms linked one M. africanum subtype I genotype with the dassie bacillus and M. microti with M. pinnipedii, thereby suggesting closer evolutionary ties within each pair of species than had been previously thought. Overall, the presented data add to the genetic definitions of several MTC organisms as well as fine-tune current models for the evolutionary history of the MTC.Tuberculosis (TB) is an age-old, and now resurgent, infectious disease that has spread to nearly every corner of the globe. Mycobacteria that cause human and/or animal TB are grouped together within the Mycobacterium tuberculosis complex (MTC). The classical species of the MTC include Mycobacterium tuberculosis, Mycobacterium africanum (of various subtypes and variants), Mycobacterium microti, and Mycobacterium bovis (along with the widely used vaccine strain M. bovis bacillus Calmette-Guérin [BCG]) (7,38,51). Newly recognized additions to the MTC include Mycobacterium caprae and Mycobacterium pinnipedii (2, 12). Although it is not presently an officially described organism, "Mycobacterium canettii" is another widely accepted member of the MTC (85). Lastly, there exist rare MTC variants, the so-called dassie and oryx bacilli, whose standing within the MTC remains to be defined (50, 84). Historically, taxonomic segregation of the MTC has been based upon each species' unique combination of growth, morphological, physiological, and biochemical characteristics (57).Variations in geographical distribution, host preference, virulence, and relative human infectivity also differentiate the tubercle bacilli (38). Since M. tuberculosis sensu stricto is disproportionately responsible for the worldwide TB burden (38), it is of great interest to identify pote...
