INTRODUCTION Lymphocytic colitis is an uncommon intestinal disorder that presents with chronic diarrhoea. It is treatable, but in the developing world, its diagnosis may often prove difficult. Data and reports of this condition in Africa are scarce because most medical centres lack a functional gastrointestinal endoscopy unit that would aid in the diagnosis. CASE PRESENTATION We present the c...

Emerging pathogens are a growing threat to human health, agriculture and the diversity of ecological communities but may also help control problematic species. Here we investigated the diversity, distribution and consequences of emerging fungal pathogens infecting an aggressive invasive grass that is rapidly colonising habitats throughout the eastern USA. We document the recent emergence and ac...

Conventional methods to detect Salmonella spp. in foodstuffs may take up to 1 wk. Methods for pathogen detection are required. Real-time detection of Salmonella spp. will broaden our ability to screen large number of samples in a short time. This chapter describes a step-by-step procedure using an oligonucleotide probe that becomes fluorescent upon hybridization to the target DNA (Molecular Bea...

Reproduction extracts a cost in resources that organisms are then unable to utilize to deal with a multitude of environmental stressors. In the nematode C. elegans, development of the germline shortens the lifespan of the animal and increases its susceptibility to microbial pathogens. Prior studies have demonstrated germline-deficient nematodes to have increased resistance to gram negative bact...

The epiphyte Pantoea agglomerans 48b/90 (Pa48b) is a promising biocontrol strain against economically important bacterial pathogens such as Erwinia amylovora. Strain Pa48b produces the broad-spectrum antibiotic 2-amino-3-(oxirane-2,3-dicarboxamido)-propanoyl-valine (APV) in a temperature-dependent manner. An APV-negative mutant still suppressed the E. amylovora population and fire blight diseas...

Background: Helicobacter pylori (H. pylori) is a Gram-negative, microaerophilic bacteria residing in stomach area, sometime presence of H. does not demonstrate symptoms and causes disease to the host. possibly most common human pathogen, 60% world’s adult population’s guts are infested by this pathogen. Aim: Aim study was identify different age groups Haripur district examine parameters associa...

Most pathogen detection tests are imperfect, with a sensitivity < 100%, thereby resulting in the potential for a false negative, where a pathogen is present but not detected. False negatives in a sample inflate the number of non-detections, negatively biasing estimates of pathogen prevalence. Histological examination of tissues as a diagnostic test can be advantageous as multiple pathogens can ...

Wastewater reuse (WWR) technology has improved greatly in recent decades and may be an important solution to global water challenges. Nevertheless, several psychological and social barriers to widespread adoption still exist. Negative emotional reactions to WWR, known as the “yuck factor,” have been identified as central to public acceptance. The present study used a large, context-neutral, web...

Background and Objective: Gram-negative pathogens are considered the common cause of wound infections associated with increased mortality and morbidity rates. Antibiotics combination has been used to overcome this problem. Aims: In this study, we identify Gram-negative pathogens found in wound infections and assess the in-vitro efficacy of a combination of amikacin and imipenem against the resi...

Background: Klebsiella pneumonia is an opportunistic pathogen causing a great array of illness both in humans and animals responsible for high mortality rate burn patients. Aim: To determine occurrence K. wound patients to check antibiotic sensitivity pneumoniae. Methods: A retrospective cross sectional study was conducted 50 samples from Allied Hospital Faisalabad were taken isolation, identif...
