RESUMO
Anthrax is a zoonotic infection caused by Bacillus anthracis. Although the incidence of disease has been decreasing in Turkey, it is still endemic in some regions of the country. The cutaneous form of disease is the most common clinical form, usually benign and rarely causes bacteriemia and sepsis. In this report, a case of cutaneous anthrax complicated with sepsis where B.anthracis was isolated from blood and wound cultures, was presented. A 53-years-old male living in Bursa province (northwestern Turkey), admitted to the emergency ward with high fever and a lesion on the right arm. His history indicated that he is dealing with livestock breeding and injured his arm during slaughtering of a sick lamb. The infection started as a black colored painless ulcer with 2 cm in diameter on his right elbow. The case was hospitalized and penicillin G therapy was started with the preliminary diagnosis of anthrax. Bullous lesions occurred around the wound, got necrosis and integrated with the first lesion. Gram stained slides from the bullous lesions revealed capsulated gram-positive bacilli under light microscope. Gram-positive bacilli were also isolated from bullous lesions and the blood cultures. The isolates were identified and confirmed as B.anthracis by conventional and molecular methods. Antibiotic susceptibility tests were performed by E-test method and the isolates were found to be susceptible to ampicillin, tetracyclin, tigecyclin, ciprofloxacin, levofloxacin, gentamycin, chloramphenicol, erythromycin, clarithromycin, vancomycin, linezolid, daptomycin and rifampicin. The lesion became surrounded by an extensive erythema and edema and expanded to the whole arm. Moxifloxacin was initiated due to the fact that clinical progress. During the second week of the therapy, a black colored scar was observed on the wound while hyperemia and edema regressed. The necrotic tissue debridated to accelerate healing and rest of the skin defect was planned for reconstruction. The patient who had septicaemia and disseminated cellulitis was discharged after his treatment continued for 14 days. Multiple-locus variable-number tandem repeat analysis method was used for molecular epidemiological investigation. The strains isolated from the patient were identified as genotype (GK) 43 classified in A3.a major cluster, and found to be identical to those strains isolated from animals in different provinces located at central and eastern Anatolia of Turkey. In conclusion, the risk of sepsis must be considered in patients with cutaneous anthrax with appropriate follow-up and treatment plan.

Bacillus anthracis, the bacterium that causes anthrax, is an agent of bioterrorism. The most effective antimicrobial therapy for B. anthracis infections is unknown. An in vitro pharmacodynamic model of B. anthracis was used to compare the efficacies of simulated clinically prescribed regimens of moxifloxacin, linezolid, and meropenem with the "gold standards," doxycycline and ciprofloxacin. Treatment outcomes for isogenic spore-forming and non-spore-forming strains of B. anthracis were compared. Against spore-forming B. anthracis, ciprofloxacin, moxifloxacin, linezolid, and meropenem reduced the B. anthracis population by 4 log(10) CFU/ml over 10 days. Doxycycline reduced the population of this B. anthracis strain by 5 log(10) CFU/ml (analysis of variance [ANOVA] P = 0.01 versus other drugs). Against an isogenic non-spore-forming strain, meropenem killed the vegetative B. anthracis the fastest, followed by moxifloxacin and ciprofloxacin and then doxycycline. Linezolid offered the lowest bacterial kill rate. Heat shock studies using the spore-producing B. anthracis strain showed that with moxifloxacin, ciprofloxacin, and meropenem therapies the total population was mostly spores, while the population was primarily vegetative bacteria with linezolid and doxycycline therapies. Spores have a profound impact on the rate and extent of killing of B. anthracis. Against spore-forming B. anthracis, the five antibiotics killed the total (spore and vegetative) bacterial population at similar rates (within 1 log(10) CFU/ml of each other). However, bactericidal antibiotics killed vegetative B. anthracis faster than bacteriostatic drugs. Since only vegetative-phase B. anthracis produces the toxins that may kill the infected host, the rate and mechanism of killing of an antibiotic may determine its overall in vivo efficacy. Further studies are needed to examine this important observation.

Bacillus anthracis has posed a threat of becoming biological weapons of mass destruction due to its virulence factors encoded by the plasmid-borne genes, such as lef for lethal factor. We report the development of a fast and sensitive anthrax DNA biosensor based on a photonic crystal structure used in a total-internal-reflection configuration. For the detection of the lef gene, a single-stranded DNA lef probe was biotinylated and immobilized onto the sensor via biotin-streptavidin interactions. A positive control, lef-com, was the complementary strand of the probe, while a negative control was an unrelated single-stranded DNA fragment from the 16S rRNA gene of Acinetobacter baumannii. After addition of the biotinylated lef probe onto the sensor, significant changes in the resonance wavelength of the sensor were observed, resulting from binding of the probe to streptavidin on the sensor. The addition of lef-com led to another significant increase as a result of hybridization between the two DNA strands. The detection sensitivity for the target DNA reached as low as 0.1 nM. In contrast, adding the unrelated DNAs did not cause an obvious shift in the resonant wavelength. These results demonstrate that detection of the anthrax lef by the photonic crystal structure in a total-internal-reflection sensor is highly specific and sensitive.

To prove linkage between an environmental sample and an anthrax case, there must be isolates obtained from both that can be compared. Although Bacillus anthracis is easily isolated from powder samples, isolating it from soil is difficult because of the high bacterial count in it. Formulations of PLET were prepared, inoculated with B. anthracis, B. cereus and B. thuringiensis and examined for growth. Two hundred eighty-three isolates including 23 B. anthracis were placed onto one formulation while MICs against trimethoprim-sulfamethoxazole were determined. The media supported B. anthracis growth at 30 degrees C and inhibited almost all other bacterial growth, including closely-related species. Sensitivity for B. anthracis and selectivity against other Bacillus and against non-Bacillus were 96.8%, 100% and 97.2% respectively. Isolates that grew had MICs >4 and >76 microg mL(-1) against trimethoprim and sulfamethoxazole, respectively. Soils spiked with 10(2)B. anthracis spores and suspended in PLET broth yielded a 6-7 log(10) increase in B. anthracis. Other growth was inhibited. PLET supplemented with sulfamethoxazole (38 microg mL(-1)), trimethoprim (2 microg mL(-1)), polymyxin B (15,000 U L(-1)), and lysozyme (150,000 U L(-1)) can successfully select for B. anthracis and will facilitate agricultural, environmental and forensic investigations of B. anthracis isolates.

A new method to stabilize and functionalize surfaces for surface-enhanced Raman spectroscopy (SERS) is demonstrated. Atomic layer deposition (ALD) is used to deposit a sub-1-nm alumina layer on silver film-over-nanosphere (AgFON) substrates. The resulting overlayer maintains and stabilizes the SERS activity of the underlying silver while presenting the surface chemistry of the alumina overlayer, a commonly used polar adsorbent in chromatographic separations. The relative affinity of analytes for alumina-modified AgFON substrates can be determined by their polarity. On the basis of SERS measurements, dipicolinic acid displays the strongest binding to the ALD alumina-modified AgFON among a set of pyridine derivatives with varying polarity. This strong affinity for carboxylate groups makes the SERS substrate an ideal candidate for bacillus spores detection using the dipicolinate biomarker. The SERS signal from extracted dipicolinate was measured over the spore concentration range 10(-14)-10(-12) M to determine the saturation binding capacity of the alumina-modified AgFON surface. The adsorption constant was determined to be Kspore = 9.0 x 10(13) M(-1). A 10-s data collection time is capable of achieving a limit of detection of approximately 1.4 x 10(3) spores. The shelf life of prefabricated substrates is at least 9 months prior to use. In comparison to the bare AgFON substrates, the ALD-modified AgFON substrates demonstrate twice the sensitivity with 6 times shorter data acquisition time and 7 times longer temporal stability. ALD expands the palette of available chemical methods to functionalize SERS substrates, which will enable improved and diverse chemical control over the nature of analyte-surface binding for biomedical, homeland security, and environmental applications.

OBJECTIVES: Sublethal ionizing doses of radiation increase the susceptibility of mice to Bacillus anthracis Sterne infection. In this study, we investigated the efficacy of clindamycin in 60Co-gamma-photon-irradiated and sham-irradiated mice after intratracheal challenge with B. anthracis Sterne spores. Clindamycin has in vitro activity against B. anthracis and inhibits the production of toxin from other species, although no direct evidence exists that production of B. anthracis toxin is inhibited. METHODS: Ten-week-old B6D2F1/J female mice were either sham-irradiated or given a sublethal 7 Gy dose of 60Co-gamma-photon radiation 4 days prior to an intratracheal challenge with toxigenic B. anthracis Sterne spores. Mice were treated twice daily with 200 mg/kg clindamycin (subcutaneous or oral), 100 mg/kg moxifloxacin (oral), 50 mg/kg ciprofloxacin (subcutaneous) or a combination therapy (clindamycin + ciprofloxacin). Bacteria were isolated and identified from lung, liver and heart blood at five timed intervals after irradiation. Survival was recorded twice daily following intratracheal challenge. RESULTS: The use of clindamycin increased survival in gamma-irradiated and sham-irradiated animals challenged with B. anthracis Sterne in comparison with control mice (P < 0.001). Ciprofloxacin-treated animals had higher survival compared with clindamycin-treated animals in two experiments, and less survival in a third experiment, although differences were not statistically significant. Moxifloxacin was just as effective as clindamycin. Combination therapy did not improve survival of sham-irradiated animals and significantly decreased survival among gamma-irradiated animals (P = 0.01) in comparison with clindamycin-treated animals. B. anthracis Sterne was isolated from lung, liver and heart blood, irrespective of the antimicrobial treatment. CONCLUSIONS: Treatment with clindamycin, ciprofloxacin or moxifloxacin increased survival in sham-irradiated and gamma-irradiated animals challenged intratracheally with B. anthracis Sterne spores. However, the combination of clindamycin and ciprofloxacin increased mortality associated with B. anthracis Sterne infection, particularly in gamma-irradiated animals.

A review of the literature suggests that the major neurologic symptom complex of infection by Bacillus anthracis is a fulminant and rapidly fatal hemorrhagic meningoencephalitis and that the reported initial mode of entry can be via the cutaneous or inhalation route. For febrile patients with acute neurologic deterioration with associated findings of dark necrotic pustules on the extremities, gram-positive rods in the cerebrospinal fluid, and multifocal areas of unexplained intracerebral hemorrhage on computed tomographic scans, anthrax should be considered within the differential diagnosis. A low cerebrospinal fluid glucose level has been reported, with gram-positive rods often noted on the gram stain of the cerebrospinal fluid in severely affected patients. Reports indicate that death usually occurs within a week.

The disease caused by Bacillus anthracis is one of the most critical concerns to the general public and public health authorities due both to the anthrax cases caused by the intentional release of the germ in the USA at the close of 2001 when letters and packages were contaminated with anthrax spores, and the current threat of biological warfare. After a brief excursus on the history of the terms Anthrax and Carbuncle, we survey the main evidence of anthrax found in the ancient literature, and deal with the identification of the pathogenic agent responsible for the disease and the subsequent discovery of the first anthrax vaccine and its use in order to control the spread of the disease in the cattle. Finally, we examine some of the most important episodes of occupational exposure to the Bacillus anthracis that occurred in the past two centuries and the preventive measures applied both to employees and the workplace.

We demonstrate that Bacillus anthracis may be detected from a formalin-fixed, paraffin-embedded biopsy specimen, even after the patient has received antibiotic treatment. Although traditional PCR methods may not be sufficiently sensitive for anthrax detection in such patients, cycle numbers can be increased or PCR can be repeated by using an aliquot from a previous PCR as the template.

In light of recent events, anthrax has once again taken center stage in the world of science and the world in which we live. Because patients with anthrax may initially present to otolaryngology clinics, it is important for the otolaryngologist to know how to diagnose and treat this entity. This article will present current information on epidemiology, microbiology, pathogenesis/clinical manifestations, diagnosis, and treatment with a particular interest in the head and neck region.

AIMS: To investigate methods of improving anthrax spore detection with PLET. METHODS AND RESULTS: Comparisons were made of PLET and blood-supplemented PLET to recover and distinguish spores of a variety of Bacillus species. Heat and ethanol purification of spores, and spore extraction from soil with water and high specific gravity sucrose plus non-ionic detergent, were also carried out. CONCLUSION: PLET was more selective and suitable than blood-supplemented PLET for detection of anthrax spores in the environmental specimens. However, PLET is not an optimal spore recovery medium. Purification of spores with ethanol was as effective as heat purification. High specific gravity sucrose plus detergent extraction solutions may be more sensitive than extraction with water. SIGNIFICANCE AND IMPACT OF THE STUDY: This study highlights shortcomings with the standard PLET isolation of anthrax spores and describes ways in which the procedure may be improved.

A 54-year-old female farmer with anthrax infection of the eyelids is presented. She was initially managed with high dose intravenous penicillin G treatment. Following complete healing of the eyelid lesions, significant cicatricial ectropion resulted. Her right lower eyelid ectropion was corrected by surgical reconstruction using full thickness skin graft after a period of 6 months during which the cicatrization process stabilized. Satisfactory cosmetic and functional improvement was achieved. Anthrax of the eyelid must be considered in the differential diagnosis of preseptal or orbital cellulitis and any reconstructive procedure should be attempted only after the cessation of the healing process.
