Differential effects of antibiotics on neutrophils exposed to lipoteichoic acid derived from Staphylococcus aureus Ann. Clin. Microbiol. Antimicrob. (IF 2.705) Pub Date : 2020-11-03 Marquerita Algorri; Annie Wong-Beringer
Persistent bacteremia occurs in at least 30% of patients with Staphylococcus aureus bloodstream infection (SAB) and may be attributable to a dysregulated host immune response. Neutrophils interact with a variety of S. aureus microbial factors, including lipoteichoic acid (LTA), to activate phagocytic function in a concentration-dependent manner. Antibiotics have been shown to exert both direct antimicrobial

Multi-Drug Resistant (MDR) Pseudomonas aeruginosa is one of the most important bacterial pathogens that causes infection with a high mortality rate due to resistance to different antibiotics. This bacterium prompts extensive tissue damage with varying factors of virulence, and its biofilm production causes chronic and antibiotic-resistant infections. Therefore, due to the non-applicability of antibiotics

Multidrug-resistant tuberculosis (MDR-TB) is burgeoning globally, and has been a serious challenge in TB management. Clinically, the ability to identify MDR-TB is still limited, especially in smear-negative TB. The aim of this study was to develop a nomogram for predicting MDR-TB. Demographics and clinical characteristics of both MDR-TB and drug-susceptible TB patients were utilized to develop a nomogram

Multi-drug resistant and extended-spectrum β-lactamases producing bacterial uropathogens among pregnant women in Northwest Ethiopia. Ann. Clin. Microbiol. Antimicrob. (IF 2.705) Pub Date : 2020-06-03 Sirak Biset,Feleke Moges,Demeke Endalamaw,Setegn Eshetie
Above 80% of urinary tract infections are caused by enteric bacteria, which are known for years by their drug-resistant ability. Though the prevalence of drug-resistant strains is increasing in the world, it is not well known in low-income countries. The aim of this study was to assess the prevalence of Multi-drug resistance, Extended-spectrum β-lactamases production, and associated risk factors among

Emerging high-risk ST101 and ST307 carbapenem-resistant Klebsiella pneumoniae clones from bloodstream infections in Southern Italy. Ann. Clin. Microbiol. Antimicrob. (IF 2.705) Pub Date : 2020-06-01 Daniela Loconsole,Marisa Accogli,Anna Lisa De Robertis,Loredana Capozzi,Angelica Bianco,Anna Morea,Rosanna Mallamaci,Michele Quarto,Antonio Parisi,Maria Chironna
Carbapenem-resistant Klebsiella pneumoniae (CR-KP) is an urgent public health issue in Italy. This pattern of resistance is due mainly to dissemination of carbapenemase genes. Molecular characterization of carbapenem-resistant Klebsiella pneumoniae (CR-KP) strains was performed over a three-year period. In-depth analysis was performed on a subset of emerging CR-KP ST101 and ST307 clones. A prospective

Ivermectin, a new candidate therapeutic against SARS-CoV-2/COVID-19. Ann. Clin. Microbiol. Antimicrob. (IF 2.705) Pub Date : 2020-05-30 Khan Sharun,Kuldeep Dhama,Shailesh Kumar Patel,Mamta Pathak,Ruchi Tiwari,Bhoj Raj Singh,Ranjit Sah,D Katterine Bonilla-Aldana,Alfonso J Rodriguez-Morales,Hakan Leblebicioglu
The recent report by Caly et al., describing the antiviral potential of ivermectin against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in vitro arrive to the agenda of potential candidates for COVID-19 treatment [1]. This discovery gave hope to the researchers who are screening for drugs that can be repurposed for treating the Coronavirus Disease 2019 (COVID-19). Ivermectin, is

Presence of Borrelia miyamotoi infection in a highly endemic area of Lyme disease. Ann. Clin. Microbiol. Antimicrob. (IF 2.705) Pub Date : 2020-05-30 Luis A Marcos,Kalie Smith,Kelsey Reardon,Fredric Weinbaum,Eric D Spitzer
A series of cases in the Northeast of the US during 2013–2015 described a new Borrelia species, Borrelia miyamotoi, which is transmitted by the same tick species that transmits Lyme disease and causes a relapsing fever-like illness. The geographic expansion of B. miyamotoi in the US also extends to other Lyme endemic areas such as the Midwestern US. Co-infections with other tick borne diseases (TBD)

Anticipating the impact of the COVID-19 pandemic on TB patients and TB control programmes. Ann. Clin. Microbiol. Antimicrob. (IF 2.705) Pub Date : 2020-05-23 Toyin Togun,Beate Kampmann,Neil Graham Stoker,Marc Lipman
The COVID-19 pandemic has currently overtaken every other health issue throughout the world. There are numerous ways in which this will impact existing public health issues. Here we reflect on the interactions between COVID-19 and tuberculosis (TB), which still ranks as the leading cause of death from a single infectious disease globally. There may be grave consequences for existing and undiagnosed

New ST623 of Cryptococcus neoformans isolated from a patient with non-Hodgkin's lymphoma in the Brazilian Amazon. Ann. Clin. Microbiol. Antimicrob. (IF 2.705) Pub Date : 2020-05-20 Lucyane Mendes Silva,William Antunes Ferreira,Roberto Alexandre Alves Barbosa Filho,Marcus Vinícius Guimarães Lacerda,Guilherme Motta Antunes Ferreira,Maria de Nazaré Saunier,Marielle Machado Macedo,Denise de Almeida Cristo,Marla Jalene Alves,Ani Beatriz Jackisch-Matsuura,Cristina Motta Ferreira
BACKGROUND Cryptococcosis is a disease of wide geographic distribution. It is most critical when it affects immunocompromised patients, with AIDS, tuberculosis or other diseases that require prolonged hospitalization. METHODS This study described a case report, molecular epidemiology, the phylogenetic relationship, along with antifungal susceptibility test of a new ST 623 of C. neoformans isolated

Venezuelan equine encephalitis virus: the problem is not over for tropical America. Ann. Clin. Microbiol. Antimicrob. (IF 2.705) Pub Date : 2020-05-19 Camilo Guzmán-Terán,Alfonso Calderón-Rangel,Alfonso Rodriguez-Morales,Salim Mattar
The equine encephalitis viruses, Venezuelan (VEEV), East (EEEV) and West (WEEV), belong to the genus alphavirus, family Togaviridae and still represent a threat for human and animal public health in the Americas. In both, these infections are characterized by high viremia, rash, fever, encephalitis and death. VEEV encephalitis is similar, clinically, to other arboviral diseases, such as dengue, Zika

AIMS The coronavirus disease 2019 (COVID-19) is characterized as highly contagious and deadly; however there is no credible and convenient biomarker to predict the severity of the disease. The aim of the present study was to estimate whether the CRP level is able to act as a marker in indicating the severity of COVID-19. METHODS Patients who complained cough or chest pain with or without fever were

Characterisation of antibiotic resistance, virulence, clonality and mortality in MRSA and MSSA bloodstream infections at a tertiary-level hospital in Hungary: a 6-year retrospective study. Ann. Clin. Microbiol. Antimicrob. (IF 2.705) Pub Date : 2020-05-07 Andrea Horváth,Orsolya Dobay,Judit Sahin-Tóth,Emese Juhász,Júlia Pongrácz,Miklós Iván,Enikő Fazakas,Katalin Kristóf
BACKGROUND Staphylococcus aureus bloodstream infections (BSI) cause significant morbidity and mortality due to the frequent antibiotic resistance, toxin and adhesin production of the bacterium. These characteristics differ significantly in methicillin resistant (MRSA) and methicillin sensitive S. aureus (MSSA) and also among isolates of different MRSA clones, contributing to the outcome of S. aureus
