Group 3 of outer membrane proteins (OMPs) of Brucella includes Omp25 and Omp31, which share 34% identity. Omp25 is highly conserved in Brucella species, and Omp31 is present in all Brucella species, except Brucella abortus. Antibodies to Brucella melitensis Omp31 have been sought only in infected sheep, and Western blotting of sera from infected sheep did not reveal anti-Omp31 reactivity. We ob...

Primary sternal osteomyelitis is a rare disease. Common infectious organisms causing primary sternal osteomyelitis include Staphylococcus aureus and Pseudomonas aeruginosa. Actinomyces species are common saprophytes of the oral cavity, but there have been few reports in the literature of primary sternal osteomyelitis caused by Actinomyces species. We describe a case of primary sternal osteomyel...

Xanthogranulomatous osteomyelitis is a very rare form of chronic osteomyelitis which presents like a bone tumor. Three cases of xanthogranulomatous osteomyelitis have been described previously in the literature. We present a case of xanthogranulomatous osteomyelitis occurring in the distal part of tibia. This case presented as swelling in a 13-year-old boy. Simple curettage proved to be curativ...

In elderly persons, osteomyelitis is second only to soft-tissue infection as the most important musculoskeletal infection. Acute osteomyelitis is usually acquired hematogenously, and the most common pathogen is Staphylococcus aureus. Acute osteomyelitis can usually be cured with antimicrobial therapy alone. In contrast, chronic osteomyelitis may be caused by S. aureus but is often due to gram-n...

Brucellosis is a worldwide zoonosis causing reproductive failures in livestock. It is shown that although the vaccine can prevent abortion, it does not provide complete protection against infection. So that vaccination of ewes with Rev.1 biotype can be a source of cattle and even human Brucellosis. The aim of this study was to evaluate possibility of Brucella cross-infection in cattle from Bruc...

Brucella species are important human and animal pathogens. Though, only little is known about mobile genetic elements of these highly pathogenic bacteria. To date, neither plasmids nor temperate phages have been described in brucellae. We analyzed genomic sequences of various reference and type strains and identified a number of putative prophages residing within the Brucella chromosomes. By in...

Osteomyelitis is classified into three groups according to its origin: osteomyelitis that originates from the blood supply, osteomyelitis related to bone disease or vascular disease, and osteomyelitis related to a local infection of dental or non-dental origin. The present case involved osteomyelitis related to a local infection of dental origin and was located in the rear area of the lingula o...

The earlier literature on osteomyelitis of very young infants dealt largely with osteomyelitis of the jaw and its probable relationship to mastitis in the nursing mother (Marx, 1920; Bass, 1928; Karplus, 1928; Wilensky, 1932; Poncher and Blayney, 1934). Metastatic osteomyelitis due to umbilical sepsis was mentioned by Fraser (1924) who collected some 30 cases over a period of four years. He sai...

Rib osteomyelitis is a rare disease, occurring in ~1% or less of all cases of haematogenous osteomyelitis. During the last century, 58 cases of rib osteomyelitis were reported in the literature, of which, multiple ribs were involved in only five patients. Because of its rarity and non-specific clinical signs, diagnostic of rib osteomyelitis may be delayed. We report a case of multifocal rib ost...

Tuberculous osteomyelitis is an uncommon infection that usually involves the vertebrae. An otherwise healthy young man with a chronic discharging sinus on his right foot caused by tuberculous osteomyelitis is described. The risk factors, clinical features, radiological findings, and investigations of tuberculous osteomyelitis are briefly reviewed. Tuberculous osteomyelitis usually runs an insid...
