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. Expand
Source attribution of food-borne zoonoses in New Zealand: a modified Hald model.
TLDR
This article describes the development of several modifications that can be used to adapt the Hald model, which has several advantages over the original approach, which include the introduction of uncertainty in the estimates of source prevalence and an improved strategy for identifiability. Expand
Molecular epidemiology of Cryptosporidium subtypes in cattle in England.
TLDR
The spatial scan statistic detected a cluster of subgenotype IIaA15G2R1 comprising seven farms, which suggests local transmission of the parasite between farms and intervention strategies should be considered to reduce the threat to public health. Expand
Occurrence of Clostridium perfringens β2-toxin amongst animals, determined using genotyping and subtyping PCR assays
TLDR
A significant association between C. perfringens possessing the β2-toxin gene and diarrhoea in piglets was identified, suggesting that β2 -toxin may play a key role in the pathogenesis of the disease. Expand
Infection in social networks: using network analysis to identify high-risk individuals.
TLDR
Simulation studies using susceptible-infectious-recovered models were conducted to estimate individuals' risk of infection and time to infection in small-world and randomly mixing networks and the ability of measures of network centrality to identify high-risk individuals was assessed. Expand
Prevalence and risk factors for Cryptosporidium spp. infection in young calves.
TLDR
The results suggest that intervention strategies should be targeted at calves under 21 days old, which represent a significant reservoir of infection on the farm and may also pose a risk to public health, assuming that the species and genotypes shed are zoonotic pathogens. Expand
Risk Factors for Campylobacteriosis of Chicken, Ruminant, and Environmental Origin: A Combined Case-Control and Source Attribution Analysis
TLDR
This is the first case-control study in which risk factors for campylobacteriosis are investigated in relation to the attributed reservoirs based on MLST profiles and showed that genotype-based source attribution is epidemiologically sensible. Expand
Assigning the source of human campylobacteriosis in New Zealand: a comparative genetic and epidemiological approach.
TLDR
The comparative-modeling and molecular sentinel surveillance approach proposed in this study provides new opportunities for the management of zoonotic diseases. Expand
Molecular Epidemiology of Campylobacter jejuni Isolates from Wild-Bird Fecal Material in Children's Playgrounds
TLDR
It is suggested that feces from wild birds in playgrounds could contribute to the occurrence of campylobacteriosis in preschool children. Expand
Molecular Epidemiology of Campylobacter jejuni Populations in Dairy Cattle, Wildlife, and the Environment in a Farmland Area
TLDR
The segregated distribution of genotypes among samples from different sources suggests that their transmission to humans is perhaps via independent routes, which suggests that both restricted and interconnecting pathways of transmission may be operating in the dairy farmland environment. Expand
