Summary
Wildlife carcass decomposition can increase temperatures and alter pH, potentially inactivating pathogens. However, these changes may not be sufficient to eliminate viruses like African swine fever.
Area of Science:
- Environmental Science
- Wildlife Pathology
- Ecology
Background:
- Infectious wildlife diseases pose risks to wildlife, domestic animals, and human health.
- Natural carcass decomposition may reduce pathogen viability through thermal and pH changes.
Purpose of the Study:
- To investigate temperature and pH changes during wild boar carcass decomposition.
- To assess the potential of these changes for pathogen inactivation.
Main Methods:
- Monitoring internal carcass temperatures of 64 wild boar carcasses.
- Measuring soil pH beneath 74 carcasses.
- Analyzing muscle and rectal tissue pH from 12 carcasses.
Main Results:
- Carcass temperatures peaked at 58°C during summer aerobic decomposition.
- Carcass pH increased from 4 to over 8.
- Soil pH rose above 9 and remained stable post-skeletonization.
Conclusions:
- Carcass decomposition creates significant temperature and pH shifts.
- These conditions likely insufficient for inactivating pathogens like African swine fever virus.

01:23Physical Methods for Controlling Microbial Growth: Temperature
256
Heat is a widely used method to control microbial growth by targeting and denaturing cellular proteins, thereby killing or inactivating microbes. This method's effectiveness is quantified using parameters such as the thermal death point (TDP), thermal death time (TDT), and decimal reduction time (D value). TDP represents the lowest temperature at which all microorganisms in a liquid suspension are eliminated within 10 minutes, whereas TDT is the time necessary to achieve sterilization at a...

01:27Factors Influencing Microbial Growth: Temperature
212
Microorganisms display remarkable adaptations, enabling them to thrive in diverse ecological niches across a wide range of temperatures. Temperature profoundly influences microbial growth by affecting enzymatic activity, membrane fluidity, and other cellular processes.Each microorganism operates within a specific temperature range defined by three cardinal points: minimum, optimum, and maximum. Below the minimum temperature, membranes lose fluidity, halting transport processes. Above the...

01:25Increased Body Temperature
2.2K
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

01:30Diversity of Archaea I
108
Archaea, a domain of single-celled microorganisms, are classified into five major phyla based on genetic and biochemical characteristics: Euryarchaeota, Crenarchaeota, Thaumarchaeota, Korarchaeota, and Nanoarchaeota. Among these, the phylum Euryarchaeota is notable for its remarkable diversity in morphology, metabolism, and ecological adaptations.Morphological and Metabolic DiversityMembers of Euryarchaeota exhibit a variety of cellular shapes, including rods and cocci. Their metabolic pathways...

01:29Factors Influencing Microbial Growth: pH
226
Microorganisms are classified as acidophiles, neutrophiles, or alkaliphiles based on their pH growth preferences, reflecting their adaptations to specific environments. Maintaining a stable intracellular pH is critical for macromolecular stability and enzymatic activity, which can be challenged by external pH variations.Neutrophiles, such as Escherichia coli, grow optimally between pH 5.5 and 8.0. These microorganisms inhabit neutral or slightly acidic environments and employ mechanisms like...
