Bacteriology and Antibiogram of pathogens isolated from wound infections at Cheshire Hall Medical Laboratory, Turks and Caicos Islands

To identify pathogens that are frequently isolated from wound infections in the Turks and Caicos Islands and formulate antibiogram based on their patterns of antimicrobial susceptibility. Bacteriology and antimicrobial susceptibility data from 1343 wound swabs cultured at the Cheshire Hall Medical Laboratory between January 2013 and November 2015 were retrospectively analyzed. The Kirby-Bauer disc diffusion technique was used to perform antimicrobial susceptibility testing. 79.1% of the 1343 swabs cultured were positive yielding a total of 1687 bacterial isolates. Frequently isolated bacteria included Staphylococcus aureus which accounted for 27.6% of isolates, approximately a third of which were methicillin resistant, Pseudomonas spp. (12.1%), Proteus spp. (8.2%), Enterococcus spp. (7.8%), E. coli (7.2%), Streptococcus agalactiae (6.1%), Klebsiella spp. (5.5%), Acinetobacter spp. (4.3%), coagulase negative Staphyloccus (4.0%) and Enterobacter spp. (3.7%). The overall highest resistance rates were seen among tetracycline (46.3%), erythromycin (37.6%) and ceftriaxone (34.2%). Imipenem, penicillin, meropenem and vancomycin had sensitivity rates ranging from 92.3% to 99.5%. Individual resistance rates varied among isolates, some differing significantly from overall rates. When tested against antibiotics routinely used to treat Pseudomonas spp., resistance rates ranged from 1.4-55.5%.

Estimation of Pathogen Proportions of Infectious Diseases: Models, Approaches and Evaluations

Attribution of etiology for disease syndromes is critical to guide appropriate public health interventions. Partial latent class analysis model (pLCM) methods have recently been developed to address this area of research; however, model parameters, assumptions, and performance are not well understood for the general etiology problem.

The Roles of IL-33 and TGF-Β1 in the Pathogenesis of Stevens-Johnson Syndrome/ Toxic Epidermal Necrolysis: Potential Biomarkers for Disease Severity

MicroscopyStevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a disease continuum of potentially life threatening, severe allergic drug reactions which result in cellular apoptosis in the skin, mucous membranes, and ocular surface. The exact pathophysiologic mechanisms leading to this apoptosis is unclear but genetic predisposition and abnormal immune regulations play a role.

Prevalence of Mastitis and Associated risk factors in Jimma Town Dairy Farms, Western Ethiopia

Across sectional study of epidemiological risk factors and associated bacterial pathogens was conducted on 216 lactating dairy cows in jimma town from Oct. 2016 to April 2017 to determine the overall prevalence rate, associated bacterial pathogens and to assess effect of risk factors on prevalence of mastitis. Upon physical examination of udder and teats the prevalence of clinical mastitis was 2.3% at cow level and 0.96% at quarter level. Using the California mastitis test (CMT) for detection of sub clinical mastitis, the prevalence of sub clinical mastitis at cow level and quarter level was 60.65 and 38.4% respectively. The overall prevalence of mastitis was 62.96. Out of 323 (38.4%) CMT positive quarters with evidence of sub clinical mastitis, the quarter infection rate for the right rare quarter was highest (41.3%) followed by left rear (38.8%), right and left front (each 36.7%). Up on microbiological examination of milk samples for both clinical and subclinical quarters, out of a total of 331 cultured, 271(81.9%) yielded bacteria whereas 60(18.1%) yielded no bacteria. A total of 263 bacterial pathogens were isolated whereas 8 were mixed infections with more than two different colonies. The main bacterial pathogens isolated were coagulase negative staphylococci (CNS) (26.6 %), Staphylococcus aureus (24.7%), Escherichia coli (13.31%), Streptococcus species (9.13%), and Pseudomonas aeruginosa (8.8%). Other bacteria isolated with low isolation rate were micrococcus species (3.04%), Corynebacterium species (3.4%), Actinomyces pyogenes (3.8%), Bacillus species (3.42%) and other gram negative rods (3.8%). Host factors such as breed, age parity and lactation stage had significant effect on the prevalence of mastitis (p‹0.05). Managemental and environmental factors such as bedding, ventilation, frequency of barn cleaning, udder washing and use of communal towel had significant effect on the occurrence of mastitis (p‹0.05). Whereas milking practice, drainage had insignificant effect on the prevalence of mastitis (p›0.05).

Caenorhabditis elegans (C. elegans) Used as a Whole Model Organism to Identify New Anti-Infectives Therapeutic Agent for MRSA Pathogens - A Review Paper

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the greatest fears with the number of serious infections on human health regarding antibiotic resistance. It causes a wide range of infections and bacteremia, ranging from inconsequential superficial skin infections, wound suppuration, even pneumonia or deep-seated tissue infections, which may lead to sepsis and fatalities.

Dawn of the Biofilm Disease: Highlights about Biofilm in Bone and Joint & Prosthetic Joint Infections Pathogenesis, Diagnosis and Treatment

I present some key considerations of the biofilm disease as part of two complex pathologies such as bone and joint infections and prosthetic joint infections, taking into account the bacterial pathogenic factors to understand the particular nature of these infections, and to achieve an accurate diagnosis and management beyond the antimicrobial therapy. I mention some personal experience of many years in the medical microbiology laboratory and next to the patient’s bed.

United States Air Force Academy: Identifying Areas at Risk for the Persistence of Plague using the Bioagent Transport and Environmental Modeling System (BioTEMS)

Introduction: Yersinia pestis, the etiologic agent of plague, has caused major pandemics in human history and continues to be both a natural and bioterrorist threat to human populations. Plague exists in nature in either an epidemic or enzootic state. Geographic models of the epidemic state have primarily been developed using flea and reservoir species, however little is known of the enzootic state and potential cryptic reservoir species and few endemic models have been produced.

A Study of Immune Response in Nile Tilapia (Oreochromis niloticus) Fed Levamisole Incorporated Diet

This study was undertaken to evaluate the influence of levamisole on the immune enhancement of Nile tilapia (Oreochromis niloticus) against potential bacterial pathogens, Fish with weight of 98±5 g were randomly distributed into seven groups each at a rate of 20 fish per 300-L aquarium and fed on a diet containing 0.0, 250, 500, 750, 1000, 1250 or 1500 mg levamisole/kg diet for eight weeks.

Osteomyelitis of the Hip secondary to Aspergillus fumigatus - A Case Report and Comprehensive Review of the Literature

Aspergillus infection in an immunocompetent human host is a rare entity. In most cases it presents as an opportunistic pathogen in immunocompromised patients. The portal of entry is usually the respiratory tract or direct inoculation of the organism to the site. Aspergillus osteomyelitis is a debilitating and severe form of Invasive Aspergillosis.

Reduction of Bitterness and Enhancing Palatability of Cetirizine Oral Liquid Dosage Forms by Cyclodextrins

The aim of this manuscript is to study cyclodextrins (CDs) as a potential excipient to suppress bitterness and enhance palatability of pediatric liquid preparations for Cetirizine, an extremely bitter drug. Natural α, β and γ CDs; and β CD derivatives such as hydroxyl propyl (HP), randomly methylated (RM) and sulfobutyl ether (SBE) β-CDs were screened in different molar ratios of 1:1, 1:2 and 1:3 for their inhibition of the extremely bitter taste of Cetirizine using the human gustatory sensation test.
