The factorial design involved two breeds, two infection treatments (infected vs non-infected) and three dietary protein treatments (hay and wheat bran (basal diet), hay plus molasses urea block (MUB), hay plus cotton seed cake (CSC)).
The factorial experimental design involved two breeds, two infection treatments (infected vs. noninfected) and three nutrition treatments [hay plus wheat bran (basal diet), hay plus molasses urea block (MUB), hay plus cotton seed cake (CSC)].
The population is segregated into two infection states (susceptible and infected) and 70, one-year age groups (15 84 years).
Subsequently full text records with the appropriate codes were assessed by two infection control physicians who classified the wound as infected or not according to the 1992 CDC definition.
Throughout the experiment there were two infection groups (0 or 750 H. contortus third stage larvae (L3)/week).
Two infection mechanisms: the disease spreads not only by contacts between individuals, but also by contacts between individuals and infective vectors.
In addition, the proposed model may become one SIRS model with an infection vector via two infection mechanisms when (alpha= 0).
(i) there is no infection equilibria if ; (ii) there is a unique infection equilibrium if ; (iii) there are two infection equilibria and if.
In order to better explain the mechanism of spreading of epidemics, we have investigated a novel SIRS model with direct immunization via two infection mechanisms in this paper.
Based on the real mechanism of some relevant epidemic networks, our model will be constructed with the following context: Two infection mechanisms: the disease spreads not only by contacts between individuals, but also by contacts between individuals and infective vectors.
Neither did we find any substantial, quantitative immunological differences between these two infection regimes.
