Methemoglobinemia Secondary to Babesia Microti Infection: A Novel Case Report.

Background: Tick-borne illnesses and methemoglobinemia have not been known to occur together in humans. Few cases have been documented in various animals of methemoglobinemia secondary to tick-borne infections.

Case Report: A 49-year-old man with no significant medical history presented to the emergency department from an urgent care with hypoxia saturating in the mid 80s.

Infectious Aortitis Due to Species Masquerading as Lung Malignancy.

Infectious aortitis is a rare but devastating vascular infection with mortality exceeding 40%. Early diagnosis is crucial but often hampered by radiographic mimickers. We report a patient who was thought to have lung cancer but ultimately found to have an infected aortic aneurysm and bacteremia owing to species.

Association Of Smoking With Recurrence Of Pulmonary Kochs; After Completion Of Antituberculous Treatment.

Background: Smoking is one of the most important yet modifiable risk factors for incidence, morbidity, recurrence and mortality from Pulmonary Koch's or tuberculosis. This study attempted to demonstrate the association between smoking and recurrence risk of Pulmonary Koch's in Pakistani male population.

Methods: This case control study was conducted at Federal Government Tuberculosis Hospital, Rawalpindi from 2015 to 2016.

Comparison between Flow Cytometry and Traditional Culture Methods for Efficacy Assessment of Six Disinfectant Agents against Nosocomial Bacterial Species.

The present study was undertaken to compare the use of flow cytometry (FCM) and traditional culture methods for efficacy assessment of six disinfectants used in Quebec hospitals including: two quaternary ammonium-based, two activated hydrogen peroxide-based, one phenol-based, and one sodium hypochlorite-based. Four nosocomial bacterial species, , and Vancomycin-resistant , were exposed to minimum lethal concentrations (MLCs) and sublethal concentrations (1/2 MLCs) of disinfectants under study. The results showed a strong correlation between the two techniques for the presence of dead and live cell populations, as well as, evidence of injured populations with the FCM.

Deadaption and readaptation with lactose, but no cross-adaptation to lactulose: a case of occult colonic bacterial adaptation.

The standard 3 h breath hydrogen (3hBH2) test distinguishes lactose maldigesters from lactose digesters. However, multiple factors impact on BH2 and care is needed to exclude a priori variables. When these factors are controlled, a negative BH2 test implies lactase persistent status or lactase nonpersistent status with colonic adaptation.

A vascular endothelial growth factor high affinity receptor 1-specific peptide with antiangiogenic activity identified using a phage display peptide library.

Vascular endothelial growth factor (VEGF) is known to play a predominant role in tumor angiogenesis and metastasis formation that is mediated by its interactions with two tyrosine kinase receptors, VEGFRI (Flt-1) and VEGFRII (KDR). Inhibition of VEGF-dependent events in tumor tissues is known to enhance apoptosis and to suppress tumor growth. A novel peptide, SP5.

Are there naturally occurring pleomorphic bacteria in the blood of healthy humans?

Dark-field microscopy of blood from healthy individuals revealed the existence of pleomorphic microorganisms. These bacteria exhibited limited growth and susceptibility to antibiotics and could be detected by fluorescent in situ hybridization and flow cytometry. They were further characterized by analysis of their 16S rRNA and gyrB genes.
