In this work, we construct and analyse an ovine brucellosis mathematical model. In this model, the population is divided into susceptible and infected subclasses. Susceptible individuals can contract the disease in two ways: (i) direct mode - caused by contact with infected individuals; (ii) indirect mode - related to the presence of virulent organisms in the environment. We derive a net reprod...
The control and eradication of brucellosis is highly desirable but heavily resource intensive as high throughput serological testing is required. The aim of this study was to meet the needs of high throughput screening laboratories involved in this process through the development of a new assay. An existing cELISA used for the serodiagnosis of brucellosis in ruminants was converted to an AlphaL...
background : brucellosis is a major bacterial zoonosis of global importance with the causative organisms of gram-negative facultative intracellular pathogens. the aims of this study were to standardize two immunoelectrophoretic techniques, rocket and cross immunoelectrophoresis, and compare their results with other conventional serodiagnostic tests. methods : sera from 15 sheep, without any his...
this cross-sectional study was conducted to estimate seroprevalence and to identify flock-level factors associated with seropositivity to brucellosis in small ruminants in kerman province, southeastern iran. in october-november 2011, serum samples were randomly collected from 1767 sheep and 1233 goats, older than 18 months, from 300 flocks. the sera were initially screened for the presence of a...
Brucellosis is still a common disease in many developing countries, particularly among farm workers, abattoir workers, and veterinarians, as well as those who rear sheep and camels. Similarly, the disease is prevalent among those who are in the habit of drinking fresh unpasteurized camel or goat milk (4). In Saudi Arabia it contributes substantially to ill health and outpatient visits (3). In o...
Following the recent discovery of new Brucella strains from different animal species and from the environment, ten Brucella species are nowadays included in the genus Brucella. Although the intracellular trafficking of Brucella is well described, the strategies developed by Brucella to survive and multiply in phagocytic and non-phagocytic cells, particularly to access nutriments during its intr...
Background: Brucellosis is endemic in the Bedouin population of southern Israel, where Poor hygiene and traditional practices including home dairy preparations, animal breeding methods contribute to disease spread. The raising of livestock has great importance in Bedouin culture. Commonly, herds of sheep, goats and camels are maintained in close proximity to living accommodations, resulting in ...
and cattle is caused by Brucella abortus, a bacterium introduced to the US via European livestock. B abortus was first detected in bison in Yellowstone National Park (YNP) in 1917 (Cheville et al. 1998), and in elk as early as 1930. In wildlife and cattle, uninfected animals contract the disease primarily by licking birth exudates of infected herd members; however, bacteria localize in a variet...
