Rheumatic heart disease is highly prevalent and associated with substantial morbidity and mortality in many resource-poor areas of the world, including sub-Saharan Africa. Primary and secondary prophylaxis with penicillin has been shown to significantly improve outcomes and is recognised to be the standard of care, with intra-muscular benzathine penicillin G recommended as the preferred agent b...

BACKGROUND High rates of 23S rDNA mutations implicated in macrolide resistance have been identified in Treponema pallidum samples from syphilis patients in many countries. Nonetheless, some clinicians have been reluctant to abandon azithromycin as a treatment for syphilis, citing the lack of a causal association between these mutations and clinical evidence of drug resistance. Although azithrom...

Leucoderma syphiliticum (LS), originally described as syphilide pigmentaire, encompasses a spectrum of dyschromic lesions that emerge during the course of secondary syphilis. Very few case reports are available in modern biomedical databases. We present the case of a 57-year-old HIV-infected male patient who presented with several round to oval, non-scaling, slightly raised and well-demarcated ...

Rheumatic heart disease (RHD), secondary to group A streptococcal infection is endemic in the developing as well as parts of the developed world with significant costs to the patient, and to the healthcare system. We briefly review the prevalence and cost of RHD in developed and developing nations. We subsequently develop a Markov model to evaluate the cost-effectiveness of three strategies (vs...

The in vivo activity of rosaramicin phosphate in disseminated and localized Treponema pallidum infections in rabbits was compared with that of penicillin G benzathine. Rabbits were injected either intradermally or intravenously to establish infection. Groups of four animals each then received either two weekly injections of 200,000 U of penicillin G benzathine, injections of 12.5 or 25 mg of ro...

Cellulitis of the lower leg is an infection caused by streptococci or, less commonly, Staphylococcus aureus and other gram-negative rods. Recurrence of cellulitis is a common problem. In the present study, we evaluated the use of monthly intramuscular injections of benzathine penicillin G to prevent recurrences of cellulitis. A total of 115 patients with definite or presumptive cases of strepto...

Penicillin acylases (PA) are widely used for the production of semi-synthetic β-lactam antibiotics and chiral compounds. In this review, the latest achievements in the production of recombinant enzymes are discussed, as well as the results of PA type G protein engineering.

the total diagnosed TB co-infection patients, 29 had active disease and were put on ATT. Nine patients had already been treated with ATT after being diagnosed with HIV infection. Patients with HBV were treated with 2NRTIs (Zidovudine + Lamivudine) + 1NNRTI (Efavirenz) and patients with syphilis were treated with Benzathine penicillin G, 2.4 MU IM in a single dose. The patients are on regular fo...

Australian and New Zealand Journal of Public Health 1 © 2015 Public Health Association of Australia Benzathine benzylpenicillin G (BPG) is a beta-lactamase antibiotic developed in 1951.1 Administered intramuscularly, BPG has low in vivo solubility, producing prolonged serum penicillin concentrations. This makes BPG suitable for treating penicillin-sensitive organisms responsive to extended, low...
