OBJECTIVES: We aimed to assess the efficacy and safety of a high loading dose of colistin and no loading dose of colistin to treat multidrug-resistant (MDR) Acinetobacter baumannii infections. METHODS: We conducted a prospective cohort study of patients with MDR A baumannii infections at a university-affiliated hospital from December 2014 to January 2016. In the high loading dose group, the patients received a high loading dose of 300 mg colistin base activity (CBA) followed by a maintenance dose of 150 mg CBA twice daily, and patients in the no loading dose group received only the maintenance dose...

REVIEW
B A Cunha, J Baron, C B Cunha
Doxycycline and, to a lesser extent, minocycline, have been used for decades to treat various serious systemic infections, but many physicians remain unfamiliar with their spectrum, interpretation of susceptibility results, pharmacokinetic/pharmacodynamic (PK/PD) properties, optimal dosing regimens, and their activity against MRSA, VRE, and multidrug-resistant (MDR) Gram-negative bacilli, e.g., Acinetobacter sp. This article reviews the optimal use of doxycycline and minocycline to treat a variety of infections and when minocycline is preferred instead of doxycycline...

The anaerobic baffled reactor (ABR) was used to treat Alkaline-surfactant-polymer (ASP) flooding wastewater in Daqing oilfield. With the ABR hydraulic retention time (HRT) was reduced from 72 hours decreased to 24 hours, the bioreactor purification capability improved gradually. After the ABR running of 100 days, the removal rate of raw oil, suspended solid and surfactant reached 99.8%, 94.4% and 50%, respectively; alkali, polymer and viscosity was removed at a rate of about 16%, 7% and 20%, respectively. There were 39 kinds of organic material detected by GCMS in the original water sample, while only 12 kinds of organics were left in the ABR outfall...

Acinetobacter baumannii ATCC 19606 can grow without lipid A, the major component of lipooligosaccharide. However, we previously reported that depletion of LpxH (the fourth enzyme in the lipid A biosynthetic pathway) prevented growth of this strain due to toxic accumulation of lipid A pathway intermediates. Here, we explored whether a similar phenomenon occurred with depletion of LpxK, a kinase that phosphorylates disaccharide 1-monophosphate (DSMP) at the 4' position to yield lipid IVA. An A. baumannii ATCC 19606 derivative with LpxK expression under the control of an isopropyl β-d-1-thiogalactopyranoside (IPTG)-regulated expression system failed to grow without induction, indicating that LpxK is essential for growth...

Acinetobacter lwoffii, a nonfermentative gram-negative aerobic bacillus, which presents in the normal flora of the oropharynx and skin, has recently been reported as a cause of human infection. Herein, the authors present a case report of peritonitis related to automated peritoneal dialysis caused by A. lwoffii.

The American Centers for Disease Control and Prevention (CDC) recognizes Acinetobacter baumannii as a source of global outbreaks and epidemics especially due to its increasing resistance to commercially available antibiotics. In this study, 69 single patient multidrug resistant isolates collected from all over Palestine, except Gaza, were studied. All the isolates were resistant to all the β-lactam antibiotics including the carbapenems. Of the 69 isolates, 82.6% were positive for blaOXA-23, 14.5% were positive for blaOXA-24, and 3% were positive for blaOXA-58...

Cis-1,2-dichloroethylene (cDCE), which is a common hazardous compound, often accumulates during incomplete reductive dechlorination of higher chlorinated ethenes (CEs) at contaminated sites. Simple monoaromatics, such as toluene and phenol, have been proven to induce biotransformation of cDCE in microbial communities incapable of cDCE degradation in the absence of other carbon sources. The goal of this microcosm-based laboratory study was to discover non-toxic natural monoaromatic secondary plant metabolites (SPMEs) that could enhance cDCE degradation in a similar manner to toluene and phenol...

Indoor microbial communities have important implications for human health, especially in health-care institutes (HCIs). The factors that determine the diversity and composition of microbiomes in a built environment remain unclear. Herein, we used 16S rRNA amplicon sequencing to investigate the relationships between building attributes and surface bacterial communities among four HCIs located in three buildings. We examined the surface bacterial communities and environmental parameters in the buildings supplied with different ventilation types and compared the results using a Dirichlet multinomial mixture (DMM)-based approach...

OBJECTIVES: Bacterial pneumonia is a common cause of death worldwide. Tea tree oil (TTO) is a potent antimicrobial natural product, which is formulated in dry powder inhalers (DPIs) for the treatment of fungal and bacterial pneumonia. METHODS: Tea tree oil-β-cyclodextrin inclusion complexes (TTO-β-CD) were prepared and characterized. Aerodynamic properties of TTO-β-CD powders were measured. The rat models of fungal (Candida albicans) and bacterial (Acinetobacter baumannii) pneumonia were prepared...

Preventive infusion of antibiotics in the mammary gland of cows consumes 11 tons/year of medically relevant antimicrobials, yet, this practice might not be critical to prevent new infections in the healthy mammary gland of cows. Here, we used next-generation sequencing and quantitative real-time PCR to determine the impact of dry cow therapy without antibiotics on milk microbiome and bacterial load, respectively. Cows diagnosed as negative for mastitis at dry off were randomly allocated to receive antibiotic (intramammary ceftiofur hydrochloride) and teat sealant or just teat sealant...

The number of infections caused by Gram-negative pathogens carrying carbapenemases is increasing, and the group of carbapenem-hydrolyzing class D β-lactamases (CHDLs) is especially problematic. Several clinically important CHDLs have been identified in A. baumannii, including OXA-23, OXA-24/40, OXA-58, OXA-143, OXA-235, and the chromosomally encoded OXA-51. The selection and dissemination of carbapenem-resistant A. baumannii strains constitutes a serious global threat. Carbapenems have been successfully utilized as last resort antibiotics for the treatment of multi-drug-resistant A...

BACKGROUND: Holarrhena antidysenterica has been employed as an ethnobotanical plant for the treatment of dysentery, diarrhoea, fever, and bacterial infections. Biological activities of the principle compound, conessine including anti-diarrhoea and anti-plasmodial effects were documented. Our previous study reported potency of Holarrhena antidysenterica extract and conessine as resistance modifying agents against extensively drug-resistant Acinetobacter baumannii. This study aimed to investigate (i) whether conessine, a steroidal alkaloid compound, could act as a resistance modifying agent against multidrug-resistant Pseudomonas aeruginosa, and (ii) whether MexAB-OprM efflux pump involved in the mechanism...

Air contamination by biological agents is often observed in medical or veterinary facilities and industrial plants. Bioaerosols may sediment and pose the surface contamination. Microorganisms present on them may become a source of infections among humans and food contamination. This study determined the use of oxidative gases, including ozone and peroxide, generated by the Radiant Catalytic Ionization (RCI) cell for the inactivation of Acinetobacter baumannii, Escherichia coli, Enterococcus faecalis, Pseudomonas aeruginosa, Salmonella Enteritidis, Listeria monocytogenes, Staphylococcus aureus, Streptococcus epidermidis, Bacillus subtilis, Clostridium sporogenes, Candida albicans, Aspergillus niger and Penicillium chrysogenumon in air and on different surfaces...

This unit describes basic protocols for infecting mice through intranasal and intraperitoneal routes with Acinetobacter baumannii to induce associated pneumonia and sepsis, the two most common manifestations of clinical infections with this pathogen. By selecting the appropriate protocols and bacterial strains of different virulence, these mouse models provide an opportunity to study the infection pathogenesis and host-immune responses, and to evaluate the efficacies of prophylactic and therapeutic anti-A. baumannii candidates...
