New hard tick (Acari: Ixodidae) reports and detection of Rickettsia in ticks from Sierra Nevada de Santa Marta, Colombia.

The Sierra Nevada de Santa Marta (SNSM), located in northern Colombia, is considered a geographical island with high levels of biodiversity and endemism. However, little is known about tick species and their associated microorganisms at the SNSM. In this study we sampled host-seeking ticks in areas of the town of Minca within the SNSM.

Molecular Detection of and Other Bacteria in Ticks and Birds in an Urban Fragment of Tropical Dry Forest in Magdalena, Colombia.

Birds are important hosts in the life cycle of some species of ticks. In Colombia, there are few eco-epidemiological studies of tick-borne diseases; the existing ones have been focused on areas where unusual outbreaks have occurred. This study describes the identification of ticks collected from birds and vegetation, and the detection of bacteria in those ticks and in blood samples from birds in an urban fragment of tropical dry forest in the department of Magdalena, Colombia.

Glutamine chelation governs the selective inhibition of Staphylococcus aureus and Salmonella typhi growth by cis-dichloro-bis(8-quinolinolato)zirconium(IV): Theory and experiment.

Quinolone-based Schiff base zirconium(IV) complex was studied as potential bacterial inhibitor against Gram-positive Staphylococcus aureus and Gram-negative Salmonella typhi growth, showing that the interaction of the complex with L-glutamine which presents in the membrane of wall leads cell death, and the mode of bacterial interaction was analyzed theoretically by DFT. Furthermore, the interaction of different amino acid residues L-alanine, D-alanine, L-lysine and D-glutamine with the metal complex through UV-vis docking studies was conducted observing that D-glutamine interacts efficiently among other amino acid residues. This observation is consistent with the interaction of the metal complex that was effective when participating in an insight of the peptidoglycan cell wall since the binding nature of glutamine potentially inhibits these microorganisms.

Physicians' and Pharmacists' Clinical Considerations for Elderly Patients with Type 2 Diabetes Mellitus: The IMPLICA2 Study.

Background: Management of elderly patients with type 2 diabetes mellitus (T2DM) is complex due to their age-related conditions. Several clinical guidelines provide specific recommendations for management of these patients but little is known about their implementation in clinical practice.

Objective: To describe physician and community pharmacist perceptions and routine clinical practice in the management of elderly T2DM patients.
