Kocuria Kristinae

Kocuria kristinae is opportunistic Gram-positive cocci from the family Micrococcaceae. It is usually considered part of the normal flora that rarely is isolated from clinical specimens. Here, we report a case of Kocuria kristinae bacteremia; to the best of our knowledge, this is the first report from Egypt.

Disk Test

The previously reported sodium polyanethol sulfonate disk test for the identification of Peptostreptococcus anaerobius (Graves et al., 1974) was evaluated, with modifications. Three bands of brucella agar, three inoculum sizes, and two inoculum sources were compared. Nine stock cultures of P. anaerobius (eight normal flora isolates and ATCC 27337) and 16 fresh clinical isolates were used. All cultures of P. anaerobius showed inhibition zones of 12 to 30 mm in diameter, regardless of test conditions. Out of 103 clinical isolates of other species of anaerobic gram-positive cocci tested, only two had an inhibition zone size in this range (one P. micros of 11 studied had a zone of 12 mm and one P. prevotii of 14 studied had a zone of 16). The test had an overall accuracy of 98% in the identification of P. anaerobius from clinical specimens. Since P. anaerobius accounts for one-fifth to one-third of all anaerobic gram-positive cocci encountered in clinical specimens, this simple and rapid technique can be very useful for presumptive identification.

Abstract Facklamia sp are Gram-positive cocci that are often mistaken for viridans streptococci, but they rarely cause invasive disease. In this report, we describe a case of mixed Facklamia sp and Streptococcus pneumoniae meningitis in an immunocompetent host with sinusitis. This case demonstrates that Facklamia sp may be part of normal human flora but can be associated with invasive disease.

This report describes Streptococcus suis meningitis with ventriculitis in a 66-year-old kushiyaki chef, which presented with fever and meningeal irritation signs. Cerebrospinal fluid testing revealed increased cell counts and protein levels, and presence of gram-positive cocci. Kushiyaki chefs are at high risk of this infection and prophylaxis should be considered.

Colonization of the gastrointestinal tract by bacteria of the normal flora was followed by bacteriological and special histological techniques in mice from several colonies. These histological techniques were designed to preserve the intimate associations that become established between particular strains of microorganisms and the epithelium of the mucosa of certain areas of the gut. The findings were as follows: 1. The various strains of bacteria of the normal flora became established in the different areas of the guts of infant mice according to a definite time sequence. 2. The first types of bacteria that could be cultured from the gut were lactobacilli and Group N streptococci. Within the first day after birth, these bacteria colonized the entire digestive tract and formed layers on the stratified squamous epithelium of the nonsecreting portion of the stomach and of the distal esophagus. 3. The bacterial types that appeared next were coliforms and enterococci. From about the 9th to the 18th day after birth, these bacteria could be cultured in extremely high numbers from the cecum and the colon. Histological sections of those organs taken during the first 2 or 3 days of that interval revealed microcolonies of Gram-positive cocci in pairs and tiny Gram-negative rods embedded in the mucous layer of the epithelium. The microcolonies were well separated from the mixture of digesta and bacteria that occupied the center of the lumen; they may have consisted of the coliforms and enterococci mentioned above; but this possibility remains to be proved. 4. Histological sections also revealed that, at about the 12th day after birth, long, thin Gram-variable rods with tapering ends were present, side by side, with the small Gram-negative rods and Gram-positive cocci in the mucous layer. By the 15th day after birth, the fusiform bacteria formed thick layers in the mucus, and seemed to be the only bacteria remaining in that location. It has not yet been possible to enumerate these tapered rods by culture methods, but as judged by visual appearances in the histological sections, they seemed to outnumber all other bacteria in the cecum and the colon by a factor of as much as 1000. It must be stressed that these bacterial layers are readily disrupted and even washed away by conventional histological techniques; their discovery was largely due to the use of the special histological techniques described in the text. The bacteriological and histological findings described here constitute further evidence for the hypothesis that symbiotic associations exist between microorganisms and animals, and that a very large percentage of the bacteria in the gastrointestinal tract constitutes a true autochthonous flora. The constant occurrence of several distinct associations of bacteria with the special histological structures of the animal host renders obsolete the notion that the intestine constitutes a chemostat in which the bacterial populations are randomly mixed. For a full understanding of the ecology of the normal microflora, it is necessary to think of body surfaces as distinct microenvironments in which virtually pure cultures of a few species of microorganisms interact with their host and the adjacent microbial populations. Experiments based on this hypothesis are admittedly difficult to design, but on the other hand studies based on the assumption that microorganisms exist as mixtures in the gastrointestinal tract will be only of limited value and may often be misleading.

Abstract Isavuconazole is a new triazole that is approved for primary therapy of invasive aspergillosis. We provide the first report of a patient with allergic bronchopulmonary aspergillosis (ABPA) who was successfully treated with isavuconazole with marked improvement and minimal adverse effects. We further review the literature on antifungal management of ABPA.

Susceptibility Evaluation

A total of 22 clinical specimens were obtained from 19 dogs with corneal ulcer (16 unilateral and three bilateral) for isolation and antimicrobial susceptibility evaluation of the isolated bacteria. Bacterial growth was observed in 100% of the samples (n=22). Staphylococcus intermedius was the predominant species (35.5%), followed by Corynebacterium xerosis (19.3%). Gentamicin, ciprofloxacin, chloramphenicol and tobramycin had a high efficacy against all of the isolated bacteria. The results evidenced that 80.7% of the isolates were Gram positive cocci and Gram positive bacilli, and that those microorganisms were sensitive to gentamicin, ciprofloxacin, chloramphenicol and tobramycin.

Oat Cell Carcinoma

A case of oat-cell carcinoma arising in the pericardium of a 51-year-old woman is described. The patient had multiple nodes; the largest was 2 × 1 cm. Two years later the patient presented with a tumor on her lower gum; this measured 2 mm and had similar characteristics to the previous one. The immunohistochemical study showed strong positivity for neuron-specific enolase. From review of the literature, it may be concluded that this is the first report of oat-cell carcinoma occurring in the pericardium.

Facial paraganglioma is an extremely rare tumor that originates from abnormal paraganglionic tissue situated in the intrapetrous facial canal. A review of the English-language literature shows that only 8 cases of facial nerve paraganglioma have been published. In each case the facial glomus presented itself sporadically, completely independent of any other form of paraganglioma. This study reports an intrapetrous facial glomus that occurred in a case of multiple paragangliomas with a hereditary pattern. To our knowledge, this is the first report of such a combination.

Introduction: Bacillus cereus is a gram positive bacilli found commonly in the soil and environment. It is a bacteria rarely associated with endocarditis. Case History: Intravenous drug abuse, presence of valvular defects, pacemakers, immunodeficiency are some of the known risk factors for B.cereus endocarditis. We present here a case series of two patients with B.cereus endocarditis along with a review of the literature. Conclusion: This is the first report of B.cereus endocarditis from India to the best of our knowledge.
