Infectious diseases is the only area of medicine where we can isolate the cause and study it in the laboratory under conditions similar to human body. Once isolated, we are able to determine the most optimal drug to treat it. Unfortunately, it is also the only specialty where after making truly wondrous strides we find ourselves at the crossroads of a public health crisis in the form of ongoing antibiotic resistance. Among the factors responsible for the current status, is the suboptimal utilization of the diagnostic microbiology laboratory. In this review authors provide a short historical perspective of diagnostic microbiology. The focus of discussion is the generation and utilization of cumulative antibiograms at the institutional and regional levels and discuss the pitfalls in large national databases with respect to the day-to-day patient care. This public health tool to slow down antibiotic resistance happens to be low-tech and inexpensive.

Objective: This study aims to examine whether the presence of mutation exists in the vitamin D-connector protein gene rs7041 variant of the pancreatitis table for patients diagnosed with coronavirus disease 2019.
Methods: A total of 113 patients with normal pancreatic enzyme levels diagnosed with coronavirus disease 2019 and 120 patients with both coronavirus disease 2019 diagnosis and high pancreatic enzyme levels were included in the study. The rs7041 genotyping of the 11th single nucleotide variation in the vitamin D-connector protein gene was determined by polymerase chain reaction and restriction fragment length polymorphism methods.

Precise and rapid disease detection is critical for controlling infectious diseases like COVID-19. Current technologies struggle to simultaneously identify viral RNAs and host immune antibodies due to limited integration of sample preparation and detection. Here, we present acoustofluidic integrated molecular diagnostics (AIMDx) on a chip, a platform enabling high-speed, sensitive detection of viral immunoglobulins [immunoglobulin A (IgA), IgG, and IgM] and nucleic acids.
