Human health, animal health (both wildlife and domestic animals), and environmental health are forever bound together. The convergence of people, animals, and the environment defines the parameters of One Health and directs attention to the impact this overlap has on public health, disease detection, and control. One Health (sometimes referred to as One Medicine) is a concept that promotes, improves, and defends the health and well-being of all species through the integration of the sciences of h...

Many septic patients are treated in emergency medicine departments or critical care units, settings in which rapid administration of targeted antibiotic therapy drastically reduces mortality. Unfortunately, current microbiology laboratory methods are too slow to support rapid interventions, typically requiring >24 hours to detect the presence of bloodstream pathogens (hematopathogens) and at least 3 to 5 days to confirm the selection of appropriate antimicrobial therapy. Moreover, cultures from septic patients are often falsely negative due to pre-emptive therapy, the presence of fastidious organisms, or microbes that are present in low density. As...

Initially, we attempted to build on past improvements of enteric plating agars containing the surfactant Niaproof 4, formerly known as Tergitol 4. However, despite their broad application for detection of Salmonella species in food safety and veterinary medical diagnostics (), Niaproof 4-supplemented (NS) enteric plating agars are limited for use on human clinical specimens because they do not adequately support the growth of Shigella species. Our goal was to develop an NS-type agar that would be sensitive for detecting Shigella as well as Salmonella species and thus be appropriate for the diagnosis of two major human bacterial enteropathogens....

In this review, we summarize the human and financial impact of sepsis, as well as the predisposing factors, symptoms, and common modes of bacterial pathogenesis. We also detail important clinical and laboratory criteria for the diagnosis of sepsis and key aspects of the Surviving Sepsis Campaign Guidelines as they relate to diagnosis, therapy, and resuscitation from the septic event. Clinical laboratories must expand their understanding of the complexities related to diagnosing and treating sepsis in order to expand their role as productive members of inter...

Four of five sera from the orienteer patients had detectable antibodies against one of the LV isolates. Researchers tracked data about the population density of Swedish voles carrying LV and compared them to various disease incidences in humans in northern Sweden. Both animal and human data support the possibility that LV causes or contributes to diabetes, fetal death, fetal malformations, and sudden infant death syndrome. Current research has raised the question of the importance of this newly recognized zoonotic pathogen within rodent vectors. Evidence indicates that it would be prudent to consider LV ...

The most common infections caused by S. aureus are those involving the skin and soft tissues (furuncles, cellulitis, and impetigo) and, less commonly, infections at deeper sites (bones, joints, and heart valves). Frequently, S. aureus produces toxin-mediated diseases, such as toxic shock syndrome, caused by the elaboration of toxic shock syndrome toxin 1, and food poisoning, caused by staphylococcal enterotoxins (). Another important toxin is Panton-Valentine leukocidin (PVL), which kills neutrophils. PVL production has been linked epidemiologically to specific infections, such as primary skin and soft tissue disease, severe necrotizing pneumonia, and severe...

Today's cruise ships serve as a gathering place for people in every age group from different countries and cultures. The closed environment aboard cruise ships, close contact among passengers and crew, and common sources of food and water provide ample opportunity for exposure to and transmission of infectious diseases. Of these, gastrointestinal and respiratory infections pose the greatest risk of outbreaks. Outbreaks on cruise ships present a public health concern, since infection is often easily spread, is difficult to control, and has the potential to disseminate pathogens. A collaborative effort between the CDC's Vessel Sanitation Program and the cruise line industry has significantly reduced the incidence of passenger ...

Approximately 10% of patients develop reactive osteitis or osteomyelitis beneath skin lesions or metastatic osteomyelitis from lymphohematogenous spread of M. ulcerans. The most plausible mode of transmission is by skin trauma at sites contaminated by M. ulcerans. Pathogenesis is mediated by a necrotizing, immunosuppressive toxin produced by M. ulcerans called mycolactone. The incidence of BU is highest in children up to 15 years old and is a public health problem in countries of endemicity due to disabling scarring and bone destruction. Today, most BU occurs in West Africa, but the disease has been reported in over 30 countries. Treatment option...

The first definitive case of human babesiosis, caused by the cattle parasite Babesia divergeus, was documented in a Yugoslavian farmer in 1957 (). Even though more than 100 species of Babesia have been described, only three distinct species are recognized as important causes of human disease. In Europe, most human infections are caused by B. divergeus (), whereas in the United States, Babesia microti accounts for most infections in the Northeast () and upper Midwest (). Another Babesia sp., characterized as the WA1-type babesial parasite, is responsible for most infections on the west coast ().

As opportunistic pathogens, Klebsiella spp. can cause a variety of illnesses including pneumonia, urinary tract infections, septicemia, soft tissue, intravenous, meningitis, liver abscess, and gastrointestinal disease, in the immunocompromised or those with underlying conditions. Current studies strongly suggest that klebsiellae, and in particular K. oxytoca, may also be associated with a variety of gastrointestinal syndromes that include antibiotic-associated hemorrhagic colitis.

The uniqueness of Bacillus relates to its ability to produce spores that can survive desiccation, heat, and cold and can germinate readily. The toxins that cause anthrax and food poisoning are encoded by plasmid-borne genes, allowing different species to have strikingly similar chromosomal DNA despite radically different phenotypes. Bacillus infections are uncommon and often associated with trauma or foreign bodies. Food poisoning caused by Bacillus spp. is much less common than other forms of bacterial food poisoning and almost always brief and self-limited. Treatment of Bacillus infections is usually straightforward once the spec...

The diagnosis of M. tuberculosis needs to be optimized and expedited for good patient management, and appropriate control measures need to be implemented to prevent transmission of tuberculosis. There are similar demands for accurate identification of the ever-increasing numbers of species of nontuberculous mycobacteria.

While some are expected (often due to cytomegalovirus or Epstein-Barr virus), others have been clinically unexpected. Pre-transplant screening is quite helpful in abrogating the risks of DDI but could be optimized further to increase patient safety, reduce risk, augment the number of organs transplanted, and save more lives. Testing thus far has largely been serologic; advances in testing technology have allowed the use of nucleic acid testing, as well as other new testing modalities. The optimal use of such testing in the solid organ transplant setting remains to be determined. Increased awareness of DDI has augmented and will continue to augment our abilit...
