Brevundimonas Vesicularis

Brevundimonas vesicularis, a non-fermenting gram-negative bacterium, has rarely been diagnosed as a cause of infection in an otherwise healthy child. In this report,we describe Brevundimonas vesicularis bacteremia, in an 8months old healthy girl who was treated successfully with intravenous piperacillin-tazobactam.

Burkholderia pseudomallei, a facultative intracellular Gram-negative bacterium casuses melioidosis, a tropical disease which is more commonly reported these days. Melioidosis can present as visceral abscess, pneumonia, localized ulcers, musculoskeletal and neurological infections, even as full blown sepsis. Melioidosis presenting as parotid abscess is commonly reported among pediatric population, however in adults it is a rare entity with only very few cases being reported. There are very limited studies that have described melioidosis with abscess in unusual sites apart from liver and splenic abscess. Here we present a case of a diabetic male with left sided parotid abscess and on microbiological evaluation found to have melioidosis which was successfully treated with combined surgical and medical treatment.

Atypical Presentations

Bartonella henselae is a Gram-negative bacterium and the causative agent of cat scratch disease (CSD). Atypical presentations of B. henselae that involve the musculoskeletal, hepatosplenic, cardiac, or neurologic systems are rare. In this case report, we describe a case of B. henselae osteomyelitis involving bilateral iliac bones complicated by hepatic lesions in a 12-year-old immunocompetent female patient. Although B. henselae is a rare cause of osteomyelitis, it should be considered when patients who present with fever, pain, and lymphadenopathy do not respond to routine osteomyelitis therapy.

Pseudomonas is a Gram-negative bacterium frequently recovered from environmental sources, particularly an aquatic environment. Epidemics of skin rash,1 otitis externa,2 isolated cases of urinary tract infections,3 and pneumonia4 have been associated with whirlpools contaminated by Pseudomonas aeruginosa. This report describes P aeruginosa otitis externa in an infant associated with a contaminated infant bath sponge. CASE REPORT K.E., a 3-month-old, first born, healthy girl was seen for drainage from the left ear. She was listless and febrile and had a moderate amount of whitish drainage from the left ear canal. There was no discharge from the right ear canal, but on examination there was right otitis media.

AbstractA cyclic tetrapeptide, designated massiliamide, was isolated from the liquid culture of the Gram-negative bacterium Massilia albidiflava DSM 17472T. The structure was elucidated through extensive spectroscopic analysis, including HR-MS and 1D and 2D NMR experiments. The absolute configuration was determined using the Marfey´s method. Massiliamide showed potent inhibitory activity towards tyrosinase with an IC50 value of 1.15 µM and no cytotoxicity.

AbstractThe Gram-negative bacterium Porphyromonas gingivalis is a secondary colonizer of the oral biofilm and is involved in the onset and progression of periodontitis. Its fimbriae, of type-V, are important for attachment to other microorganisms in the biofilm and for adhesion to host cells. The fimbriae are assembled from five proteins encoded by the mfa1 operon, of which Mfa5 is one of the ancillary tip proteins. Here we report the X-ray structure of the N-terminal half of Mfa5, which reveals a von Willebrand factor domain and two IgG-like domains. One of the IgG-like domains is stabilized by an intramolecular isopeptide bond, which is the first such bond observed in a Gram-negative bacterium. These features make Mfa5 structurally more related to streptococcal adhesins than to the other P. gingivalis Mfa proteins. The structure reported here indicates that horizontal gene transfer has occurred among the bacteria within the oral biofilm.
