SUMMARY The objective of this study was to address the impact of heterogeneity of infectious period and contagiousness on Salmonella transmission dynamics in dairy cattle populations. We developed three deterministic SIR-type models with two basic infected stages (clinically and subclinically infected). In addition, model 2 included long-term shedders, which were defined as individuals with low contagiousness but long infectious period, and model 3 included super-shedders (individuals with high…

Transmission dynamics of intramammary infections caused by Corynebacterium species.
TLDR
The rate of new infections was significantly related to preexisting IMI in both farms, underscoring the importance of preexisted Corynebacterium spp.
Modelling the effect of heterogeneity of shedding on the within herd Coxiella burnetii spread and identification of key parameters by sensitivity analysis.
Age-structured dynamic, stochastic and mechanistic simulation model of Salmonella Dublin infection within dairy herds.
Stochastic Modeling of Imperfect Salmonella Vaccines in an Adult Dairy Herd
TLDR
An effective vaccination program against Salmonella Cerro spread in the herd can be designed with vaccines with a single high efficacy in reducing either the infectious period or susceptibility of the host, or if such high efficacy vaccines are not available, vaccines with multiple moderate efficacies may be considered.
Assessing the potential impact of Salmonella vaccines in an endemically infected dairy herd.

Estimating the probability of an extinction or major outbreak for an environmentally transmitted infectious disease
TLDR
Numerical simulations illustrate important differences between the deterministic and stochastic counterparts, relevant for outbreak prevention, that depend on indirect transmission, pathogen shedding by infectious hosts, replication of free-living pathogens, and environmental decontamination.
Transmission dynamics of a multidrug-resistant Salmonella typhimurium outbreak in a dairy farm.
TLDR
Simulations of the transmission model indicated that salmonellosis outbreaks with few clinical cases were likely due to the extinction of the pathogen in the premises in the early phase of the outbreaks, and small population size and group structure within the farm decrease the on-farm persistence of the Pathogen.
Reproduction numbers for infections with free-living pathogens growing in the environment
TLDR
The utility and limitations of reproduction numbers to accurately quantify the effects of control strategies for infections with FLPs growing in the environment are highlighted.
Characterization of potential superspreader farms for bovine tuberculosis: A review
TLDR
Targeting control methods on putative superspreader farms might yield disproportionate benefits in controlling endemic bovine tuberculosis in Great Britain, however, real‐time identification of any such farms, and integration of controls with industry practices, present analytical, operational and policy challenges.

TLDR
A greater understanding of the cause of the heterogeneity in bacterial carriage could lead to highly efficient control measures to reduce the prevalence of E. coli O157 in cattle farms in Scotland.
A mathematical model of the dynamics of Salmonella Cerro infection in a US dairy herd
TLDR
A mathematical model of the transmission dynamics of salmonella was developed to describe an outbreak of S. Cerro infection that occurred in a Pennsylvania dairy herd and the basic reproduction number was calculated and relevance to the intervention strategies is discussed.
Super-shedding cattle and the transmission dynamics of Escherichia coli O157
TLDR
A comparison of alternative model fits reveals that the variation in the prevalence data is best explained when a proportion of the cattle are assumed to transmit infection at much higher levels than the rest – the so-called super-shedders.
Superspreading and the effect of individual variation on disease emergence
TLDR
It is shown that contact tracing data from eight directly transmitted diseases shows that the distribution of individual infectiousness around R0 is often highly skewed, and implications for outbreak control are explored, showing that individual-specific control measures outperform population-wide measures.

TLDR
This book discusses the biology of host-microparasite associations, dynamics of acquired immunity heterogeneity within the human community indirectly transmitted helminths, and the ecology and genetics of hosts and parasites.

From an analysis of the distributions of measures of transmission rates among hosts, we identify an empirical relationship suggesting that, typically, 20% of the host population contributes at least…
A clarification of transmission terms in host-microparasite models: numbers, densities and areas
TLDR
It is argued that the terms ‘density-dependent transmission’ and ‘frequency-dependent Transmission’ remain valid and useful, but that the Terms ‘mass action’, ‘true mass action' and “pseudo mass action” are all unhelpful and should be dropped.
Salmonellosis in calves--the effect of dose rate and other factors on transmission.
TLDR
The number of isolations from material submitted to Wallaceville Animal Research Centre for confirmation of a diagnosis of salmonellosis was only 158, or 3.9% of 3,978 cases examined over a period of eight years, suggesting that the incidence of Salmonella in the field may not be nearly as high as that found by Nottingham for stock slaughtered at the works.
