Hemoprotozoa of domestic animals in France: Prevalence and molecular characterization
Very limited information is available on epizootiology of haematozoan infections in
French domestic animals. In an attempt to address this issue, prevalence of piroplasmida
was studied in carnivores and ruminants, whereas prevalence of Hepatozoon spp. was only
investigated in carnivores. In total, 383 animals were included in the survey (namely 116
cats, 108 dogs, 91 sheep and 68 cows). Parasite diagnosis was carried out using molecular
methods such as PCR and sequencing of the 18S rRNA gene. In addition, ruminant samples
were analyzed with the reverse line blotting technique (RLB). Results of RLB and PCR plus
sequencing were in total agreement.
In carnivores, haematozoan prevalence was close to 1%. Two cats were infected by H.
canis (1.7% prevalence) and one of them was co-infected by Cytauxzoon sp. (0.8%). This
represents the first finding of both pathogens in French cats. One dog was infected by H.
canis (0.9%) and another by Babesia canis vogeli (0.9%).
In ruminants, haematozoan prevalence (piroplasmida) was significantly higher than in
carnivores (4.8% in sheep and 8.8% in cow). Theileria ovis was found in 1 sheep, Theileria sp.
in 2 sheep, Theileria buffeli in 5 cows and B. major in 1 cow.
Evidence presented in this contribution indicates that haematic protozoa are not
widely distributed in domestic mammal populations of France
Ultrasonic intensification as a tool for enhanced microbial biofuel yields
peer-reviewedUltrasonication has recently received attention as a novel bioprocessing tool for process intensification in many areas
of downstream processing. Ultrasonic intensification (periodic ultrasonic treatment during the fermentation process)
can result in a more effective homogenization of biomass and faster energy and mass transfer to biomass over short
time periods which can result in enhanced microbial growth. Ultrasonic intensification can allow the rapid selective
extraction of specific biomass components and can enhance product yields which can be of economic benefit. This
review focuses on the role of ultrasonication in the extraction and yield enhancement of compounds from various
microbial sources, specifically algal and cyanobacterial biomass with a focus on the production of biofuels. The
operating principles associated with the process of ultrasonication and the influence of various operating conditions
including ultrasonic frequency, power intensity, ultrasonic duration, reactor designs and kinetics applied for ultrasonic
intensification are also described
