A preponderance of clusters seen on direct Gram stain of blood cultures positive for gram-positive cocci was 98% sensitive and 100% specific for identification of staphylococcal species or of Peptococcus. A preponderance of chains, pairs, or both was 100% sensitive and 98% specific for identifying streptococci. Further presumptive identification of either staphylococci or streptococci based on ...

Experience in setting up an inexpensive microbiology laboratory in the Bangladesh National Society for the Blind Eye Hospital and Training Complex at Chittagong is presented, together with the results of a pilot study to identify organisms responsible in 33 consecutive cases of suppurative keratitis in the Chittagong area of Bangladesh. Of the 33 cases 21 were positively identified by means of ...

BACKGROUND Although global efforts to support routine immunization (RI) system strengthening have resulted in higher immunization rates, the World Health Organization (WHO) estimates that the proportion of children receiving recommended DPT3 vaccines has stagnated at 80% for the past 3 years (WHO Fact sheet-Immunization coverage 2014, WHO, 2014). Meeting the WHO goal of 90% national DPT3 covera...

A group of 34 mycobacteria, consisting of 25 Mycobacterium tuberculosis and nine strains of three other species, was isolated from 400 expectorated sputum specimens submitted on 148 patients from county-wide sources. Eight strains (24% of the total) were isolated from specimens evaluated by Gram stain to be oropharyngeal fluids. The remaining 26 strains were isolated from ungradable specimens a...

Technology is most commonly associated with material things, tools or artifacts. But technology is also theoretically associated with routines, patterns of action that provide capabilities. Schatzki’s practice theory allows for an overarching perspective that ties tools as devices to routines in a broader social context and offers insights into technological change, in particular, in the inform...

Profuse per rectal bleeding due to erosion of the inferior epigastric artery following a catheter tube caecostomy. Editor, We describe a case of profuse per rectal bleeding due to erosion of the right inferior epigastric artery, by a Foley catheter, used as a tube caecostomy, for decompression of underlying colonic pseudo-obstruction. Case history: A sixty-four year old male was admitted to the...

Effective polysaccharide(conjugate) vaccines against Neisseria meningitidis serogroups A, C, W, and Y have been widely used, but serogroup B meningococci remain a major cause of severe invasive meningococcal disease (IMD) worldwide, especially in infants. Recently, a vaccine, 4CMenB (Bexsero(®)), containing three recombinant proteins, and outer membrane vesicles (OMV) derived from a serogroup B...
