Immune activation alters behaviour (i.e. sickness behaviour) in animals across phyla and is thought to aid recovery from infection. Hypotheses regarding the adaptive function of different sickness behaviours (e.g. decreased movement and appetite) include the energy conservation and predator
The gastrointestinal tract hosts the natural reservoir of microbiota since birth. The microbiota includes various bacteria that establish a progressively mutual relationship with the host. Of note, the composition of gut microbiota is rather individual-specific and, normally, depends on both the
The composition and structure of microbial communities associated with mosquitoes remain poorly understood despite their important role in host biology and potential to be harnessed as novel strategies for mosquito-borne disease control. We employed MiSeq sequencing of the 16S rRNA gene amplicons to
Fever, the rise in body temperature set point in response to infection or injury, is a highly conserved trait among vertebrates, and documented in many arthropods. Fever is known to reduce illness duration and mortality. These observations present an evolutionary puzzle: why has fever continued to
Clostridioides difficile Infection (CDI) is a leading cause of healthcare-associated infections in Canada, affecting the gastrointestinal tract which can lead to fever, abdominal pain, and diarrhea. Effective treatment for patients with Recurrent CDI (rCDI) can be achieved by Fecal Microbiota
Lumpy Skin Disease (LSD) is a highly contagious viral disease affecting cattle mainly and induced by the Lumpy Skin Virus within the Capripoxvirus genus of the family Poxviridae. LSD infected animals exhibit pyrexia and sudden appearance of localized or generalized skin nodules that may slough
The soft tick Argas japonicus mainly infests birds and can cause human dermatitis; however, no pathogen has been identified from this tick species in China. In the present study, the microbiota in A. japonicus collected from an epidemic community was explored, and some putative Rickettsia pathogens
RNA interference (RNAi) has strong antiviral activity in a range of animal phyla, but the extent to which RNAi controls virus infection in chordates, and specifically mammals remains incompletely understood. Here we analyze the antiviral activity of RNAi against a number of positive-sense RNA
Cyclooxygenases (COXs) catalyze the rate-limiting step in the production of prostaglandins, bioactive compounds involved in processes such as fever and sensitivity to pain, and are the target of aspirin-like drugs. COX genes have been cloned from coral, tunicates and vertebrates, and in all the
Fever is a non-specific host defense mechanism that comprises part of the innate immune response. Innate immune function is thought to be an important adaptive immunological response to infection because it occurs across a broad diversity of phyla. Some reptiles can mount a febrile response, despite
The gopher tortoise tick, Amblyomma tuberculatum, has a unique relationship with the gopher tortoise, Gopherus polyphemus, found in sandy habitats across the southeastern United States. We aimed to understand the overall bacterial community associated with A. tuberculatum while also focusing on
There is substantial research being conducted on the relationships between the gut microbiome, the immune response and health and disease. Environmental temperature and heat stress are known to modify the gut microbiome. Changes in core temperature have been linked, in multiple phyla, to altered
BACKGROUND
The human gastrointestinal tract is inhabited by a very diverse symbiotic microbiota, the composition of which depends on host genetics and the environment. Several studies suggested that the host genetics may influence the composition of gut microbiota but no genes involved in host
We investigated the microbiota found in the vaginas of Holstein dairy cows during the transition period and described the differences in bacterial composition and total bacterial load (TBL) associated with disease and fertility. Vaginal swabs were collected at -7, 0, 3, and 7 d relative to
BACKGROUND
Microbiota inhabiting midguts of mosquitoes play a key role in the host - parasite interaction and enhance vectorial capacity of viral diseases like dengue and chikungunya fevers. Mosquito midgut is considered to be an important site for host-pathogen interaction and pathogen survival is
