“…Breed susceptibility of anaplasmosis recorded in this study support the report of (Chakraborti 2002;. However others have reported no difference in susceptibility to A. marginale of Bos taurus and Bos indicus crossbred cattle (½ to ¾ Bos indicus) (Otim et al, 1980;Wilson et al, 1980) or Bos indicus and Bos indicus crossbred cattle (Bock et al, 1999). Similarly this report revealed that crossbred cattle were mostly affected (13.26%) with Theileriasis than indigenous cattle (6.86%).…”

Abstract:A detailed cross-sectional study was carried out to investigate the prevalence and associated risk factors of theileriosis and anaplasmosis in cattle of Dinajpur district over a period of six months from January to June 2014. A total of 200 samples were randomly collected from the cattle. A pretested questionnaire was implemented to collect data on different risk factors. Blood smears were prepared and examined under microscope (100 xs) with Giemsa's stain. The study revealed proportional prevalence was 10% for theileriasis and 18.5% for anaplasmosis. The percentages of theileriasis and anaplasmosis 12.61% and 22.52% were higher in female than in male animal 6.74% and 13.48% respectively. In both cases, female showed higher positivity in compare with male. The univariate logistic regression analysis revealed cattle with a herd size >10 (OR=4.3), temperature (≥ 103ºF) (OR=3.27), presence of tick in the body surface (OR=3.09) and record of Ivermectin treatment (OR=4.47) were found significantly associated with theileriasis prevalence (p<0.05) and irregular bathing history was found significantly associated in the case of anaplasmosis prevalence (OR=0.23). However, in multivariate analysis, temperature (≥ 103ºF) (OR=2.89), presence of tick in the body surface (OR=2.80) and animal with a record of Ivermectin treatment (OR=4.24) showed significant association with theileriasis and herd size >10, deep brown; white colour and bathing history were significantly associated (P < 0.05) with the anaplasmosis. Good husbandry practice and adoption of hygienic measures are needed among the high risk group or individuals to minimize the spread of the disease.

“…Furthermore, epidemiological investigations have suggested that one-host tick species such as R . (subgenus Boophilus ) microplus and D. albipictus were associated with natural transmission of A. marginale (Bock et al, 1999; Ewing et al, 1997), which corroborates at least one report of experimental transmission (Aguirre et al, 1994). Intrastadial or transstadial transmission after interhost transfer are the most likely scenarios in such cases because transovarial transmission is considered unlikely for Anaplasmataceae (Bram and Roby, 1970; Long et al, 2003; Potgeiter, 1981; Stich et al, 1989) and because R. Boophilus microplus has been reported to transfer between bovine hosts (Mason and Norval, 1981).…”

The ehrlichioses have been subject to increasing interest from veterinary and public health perspectives, but experimental studies of these diseases and their etiologic agents can be challenging. Ehrlichia canis, the primary etiologic agent of canine monocytic ehrlichiosis, is relatively well characterized and offers unique advantages and opportunities to study interactions between a monocytotropic pathogen and both its vertebrate and invertebrate hosts. Historically, advances in tick-borne disease control strategies have typically followed explication of tick-pathogen-vertebrate interactions, thus it is reasonable to expect novel, more sustainable approaches to control of these diseases as the transmission of their associated infections are investigated at the molecular through ecological levels. Better understanding of the interactions between E. canis and its canine and tick hosts would also elucidate similar interactions for other Ehrlichia species as well as the potential roles of canine sentinels, reservoirs and models of tick-borne zoonoses. This article summarizes natural exposure studies and experimental investigations of E. canis in the context of what is understood about biological vectors of tick-borne Anaplasmataceae.

“…Bos taurus are most susceptible to infection and B. indicus least susceptible. The susceptibility of crossbred animals usually lies somewhere in the middle, but this is not the case for infection with A. marginale, as all breeds and crossbred cattle appear to be equally susceptible to disease caused by this organism (12). There is a continuum in relation to the host' s resistance to disease for other disease-causing organisms (13).…”

Control of ticks and tick-borne diseases in northern Australia is considered economically important, but is complicated due to the physical and production environment. Various approaches to analysis have been applied to evaluate decisions to control tick-borne diseases but have been used in research rather than as direct support for producer decisions. To be effective, the results from economic analysis need to be applied by decision-makers. The application of the results from economic analysis requires decision-makers and analysts to incorporate effective communication within their relationship. Taking a learning approach to enhance communication in economic advisory services has potential to overcome misalignment between the advice provided and producers' approaches to decision-making. In this approach, we need to understand the processes a livestock producer would use to evaluate their experiences and develop new understanding and knowledge over time as a result of these experiences. This paper explores the nature of private decisions in relation to tick-borne disease control then considers the use of a learning approach to enable effective learning to take place between producers and their advisors.

Effect of breed of cattle on innate resistance to infection with Anaplasma marginale transmitted by Boophilus microplus

Abstract: Innate resistance of purebred B indicus and crossbred cattle was not significantly different. The results confirm that purebred B indicus and crossbred cattle are sufficiently susceptible to warrant the use of vaccination against Anaplasma infections.
