Description of a computer program to calculate reacting supersonic internal flow fields with shock waves using viscous characteristics: Program manual and sample calculations
A computer program for calculating internal supersonic flow fields with chemical reactions and shock waves typical of supersonic combustion chambers with either wall or mid-stream injectors is described. The usefulness and limitations of the program are indicated. The program manual and listing are presented along with a sample calculation
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
