BACKGROUND Classical Swine Fever (CSFV) is one of the most important viral infectious diseases affecting wild boars and domestic pigs. The etiological agent of the disease is the CSF virus, a single stranded RNA virus belonging to the family Flaviviridae. All preventive measures in domestic pigs

A 145-acre potato field adjacent to Dorris, California, was treated with ethoprop (Mocap) to control nematodes. Ethoprop releases n-propyl mercaptan, a highly odorous and volatile gas, as a degradation product of the pesticide. An epidemiological investigation was undertaken by the California

The number of reported outbreaks of typhoid fever in the United States has recently increased. Only six were reported from 1980-1989, but seven outbreaks were reported in 1990. In August 1990, health officials in Montgomery County, Maryland, were notified of two cases of typhoid fever among persons

In May 1981 an outbreak of typhoid fever occurred in a small village on a southwestern United States Indian reservation. Five of the six culture-proven cases, but only 2 of 15 community, age-matched controls, had eaten food prepared for a party held in the village on 20 April (chi-square = 4.3; P

Insecticide resistance is a serious problem facing the effective control of insect vectors of disease. Insensitive acetylcholinesterase (AChE) confers resistance to organophosphorus (OP) and carbamate insecticides and is a widespread resistance mechanism in vector mosquitoes. Although the point

Louse-borne relapsing fever (LBRF) is known to have killed millions of people over the course of European history and remains a major cause of mortality in parts of the world. Its pathogen, Borrelia recurrentis, shares a common vector with global killers such as typhus and plague and is known for

The occupational health nurse in a large manufacturing facility arrives at work early one Monday morning to find three ill employees in the clinic waiting room and a message from several plant supervisors that multiple employees have called in sick. The supervisors are concerned. The employees have

The convergence of the microbial and human worlds provides us with everyday essentials for the survival of our species, and in turn, this interaction brings painful and tragic consequences from pathogens. Looking back, it can be seen that microbes have also changed our history. Were it not for a

BACKGROUND The efficacy of entomopathogenic fungi in pest control is mainly affected by various adverse environmental factors, such as heat shock and UV-B radiation, and by responses of the host insect, such as oxidative stress, osmotic stress and fever. In this study, an adenylate cyclase gene

We tested the hypothesis of optimal adaptation of viral infectors to eukaryotic hosts, using (1) correlation in codon and amino acid usage between organisms, and (2) canonical correlation between groups of hosts and infectors. The codon correlations between parasites and hosts vary, being low

The case of a 34-year-old otherwise healthy woman with retropharyngeal abscess due to a fishbone injury and presenting with neck stiffness and aphagia without visualization of a pharyngeal mucosal lesion is reported. The case illustrates that sore throat with symptoms out of proportion to

OBJECTIVE To describe an outbreak of salmonella food poisoning that probably was due to contamination of mashed potatoes by a foodhandler, which occurred despite a policy for routine surveillance stool cultures of kitchen employees. METHODS A case control study of 223 individuals who ate the lunch

A 60-year-old man presented with a 3-month history of nonhealing ulcer over the tip of his right thumb. The ulcer started as a blister over the tip of the thumb that later ruptured and spread proximally to cover the whole pulp area of the thumb. There was no history of trauma, fever, weight loss, or

OBJECTIVE To describe the epidemiology, natural history, and treatment of epiglottitis in the Hemophilus influenzae type B (Hib) vaccine era. METHODS Ten-year retrospective study. METHODS Tertiary-care children's hospital. METHODS Nineteen patients with a discharge diagnosis of
