In recent years leaf curl disease of cotton has become a major limiting factor in the production of cotton, which is an important fiber cash crop. In the last two decades or more, leaf curl disease in cotton took on epidemic proportions in Pakistan. In the early 1990’s cotton leaf curl disease (CLCuD) appeared in the bordering parts of India in the states of Rajasthan and Punjab and spread to e...

UNLABELLED In accord with as-low-as-reasonably-achievable and good-manufacturing-practice concepts, the present study evaluated the efficiency of radioactivity decontamination of materials commonly used in laboratory surfaces and whether solvent spills on these materials affect the findings. METHODS Four materials were evaluated: stainless steel, a surface comprising one-third acrylic resin a...

INTRODUCTION It is common in some cryosurgical procedures to rely on freeze-thaw cycle(s) to destroy undesirable tissues. Most research in cryosurgery focuses on the freezing process and much less attention has been paid to thawing or re-warming. However, as ice melts during thawing, the extracellular solution can become locally hypotonic, driving water into cells, resulting in cell expansion a...

To the Editor: Contamination of stethoscopes by skin flora has been described previously. 1 The predominant organisms recovered from stethoscope diaphragms were Staphylococcus epider-midis and Staphylococcus aureus. Previous studies documented the status of contamination of the stethoscope diaphragm with microorganisms only once, and no repeat sampling was performed. 1 The dynamic of contaminat...

The aim of this study was to determine whether a patient's endocervical swab specimen can be transported in first void urine (FVU) as combined specimens for the detection of Mycoplasma genitalium by real-time PCR. The study also compared two different DNA extraction methods for observation of possible PCR inhibition. Three specimens, one endocervical swab specimen transported in 2-SP medium, on...

Patients with Human Immunodeficiency Virus (HIV) are at the greatest risk of being infected various opportunistic infections, as their immune systems become so weak to fight against infectious agents. Candida species among commonest pathogens affecting people weakened systems. Candidiasis remains major challenge public health important HIV patients. There is scarcity information regarding impac...

The bacterial loads for gonococcal infections of the pharynx and rectum were determined among men with male sexual partners. The median bacterial load for rectal infections (18,960 copies/swab) was significantly higher than the load for pharyngeal infections (2,100 copies/swab; P = 0.001). Bacterial loads among men with symptomatic proctitis were strikingly high (median, 278,000 copies/swab).
