The business case for One Health
2014
Grace, Delia
This article outlines a pathway to develop the business case for One Health. It describes the origin and development of One Health and then identifies five potential areas where One Health can add value and reduce costs. These are: (1) sharing health resources between the medical and veterinary sectors; (2) controlling zoonoses in animal reservoirs; (3) early detection and response to emerging diseases; (4) prevention of pandemics; and (5) generating insights and adding value to health research and development. Examples are given for each category along with preliminary estimates of the potential savings from adopting the One Health approach. The literature reviewed suggests that one dollar invested in One Health can generate five dollars worth of benefits and a global investment of US$25 billion over 10 years could generate benefits worth at least US$125 billion. Conservation implications: the time has come to make the bigger case for massive investment in One Health in order to transform the management of neglected and emerging zoonoses and to save the lives of millions of people and hundreds of millions of animals whose production supports and nourishes billions of impoverished people per annum.
Mostrar más [+] Menos [-]Risk, knowledge and preventive measures of smallholder dairy farmers in northern Malawi with regard to zoonotic brucellosis and bovine tuberculosis
2014

Milk production using local cattle breed-types is an age-old practice in Malawi. Although dairy farming is becoming more common as a result of the increasing population and demand for milk and milk products, there is limited knowledge of the farmers’ awareness of zoonotic disease risks, their preventative practices and the disease burden in animals. This study determined dairy farmers’ general knowledge of zoonoses, assessed their risks for infection with zoonotic bovine tuberculosis (bTB) and brucellosis, and evaluated farm practices to prevent disease transmission. A questionnaire was drawn up and administered by the authors. It was used to collect information about the knowledge and preventive practices of 140 out of 684 registered dairy farmers at Mzuzu Agricultural Development Division, northern Malawi. During a second visit to 60 out of the 140 farms, a total of 156 and 95 cattle were tested for brucellosis and tuberculosis, respectively. Most farmers (77.1%) knew or had heard of zoonotic diseases, whilst 75.0% correctly named at least one zoonotic disease. More survey participants named tuberculosis as a zoonotic disease compared to brucellosis (74.3% versus 2.9%). The most commonly named means of transmission were milk (67.0%) and meat (56.0%). Almost all survey participants (96.4%) practised at least one farm activity that could lead to potential transmission of brucellosis or bTB, including sale (67.0%) and consumption (34.0%) of unpasteurised milk. Antibodies against brucellosis were found in 12 cattle (7.7%), whilst one animal (1.1%) reacted to the tuberculin skin test. General knowledge about possible transmission of diseases between humans and animals was high, although most farmers practised risk behaviours that could potentially expose the public to milk-borne zoonotic diseases such as brucellosis and bTB. Furthermore, some animals had positive results for brucellosis and tuberculosis tests. Therefore, improvement of zoonotic disease prevention programmes, as well as further investigation into the prevalence and risk factors for zoonoses, is recommended.

International audience | To determine pharmacodynamic cutoffs with pharmacokinetic-pharmacodynamic principles and Monte Carlo simulation (MCS) for use of amoxicillin in pigs to set interpretive criteria for antimicrobial susceptibility testing. 191 plasma disposition curves of amoxicillin obtained from 21 IV, 104 IM, and 66 PO administrations corresponding to 2,098 plasma concentrations. A population model of amoxicillin disposition in pigs was developed for PO and IM administration. The MCS method was then used to determine, for various dosage regimens, the proportion of pigs achieving plasma amoxicillin concentrations greater than a selection of possible minimal inhibitory concentrations (MICs) ranging from 0.0625 to 4 mg/L for at least 40% of a 24-hour period. A target attainment rate (TAR) of 90% was never achieved with the breakpoint recommended by the Clinical and Laboratory Standards Institute (0.5 mg/L) when the usual recommended dosage (20 mg/kg/d) was used. Only by dividing the orally administered daily dose into 12-hour administration intervals was a TAR > 90% achieved when the total dose was at least 40 mg/kg for a pathogen having an MIC ≤ 0.0625 mg/L. For the IM route, the TAR of 90% could only be achieved for MICs of 0.0625 and 0.125 mg/L with the use of 15 and 30 mg/kg doses, respectively. Population kinetics and MCS are required to determine robust species-specific interpretive criteria (susceptible, intermediate, and resistant classifications) for antimicrobial susceptibility testing breakpoints (taking into account interanimal variability).

The experiment was done to determine the effects of feeding heat stressed broilers (Ross308) diets contain Nigella Sativa seeds or coriander seeds on Ingestive, panting behaviors, feed consumption, weight gain, and feed conversion ratio, live body weight, slaughter weight, carcass weight and dressing percentage, corticosterone, triiodothyronine (T3) and tetraiodothyronine (T4). Three groups were used; the first one is the control group, which fed on basal diet only and the second fed diet contains 1% Nigella Sativa seeds (black seed) while the third group fed diet contain 2% coriander seeds. The previous parameters were recorded daily or weekly during the experiment or after slaughtering to collecting blood parameters. The results explained that, there was a significant increase in feeding behavior, feed consumption, weight gain and dressing percentage while there was a significant decrease in panting behavior, water to feed ratio, T3 level and corticosterone level. Moreover, there was no significance difference in drinking behavior live body weight, slaughter weight, feed conversion rate and T4 level (P<0.05). It could be concluded that, black seeds and coriander seeds can be used to alleviate the negative effect of heat stress in broiler during summer seasons in Egypt.

A socioeconomic study was made to assess the outcome of a tsetse and trypanosomosis control operation conducted in Chewaka settlement station, Southwest Ethiopia, during 2005-2007 through comparisons of data before and after the control program within Chewaka, and between Chewaka and a non-controlled adjacent site, Bikiltu Didessa peasant Association. Retrospective and crossectional questionnaire survey methods were used to generate data for the study. Results showed that the total livestock and cattle population in chewaka increased by 116% and 1039 %, respectively, and the total cereal production increased by 63.2 %. During this period the overall livestock and cattle population in Bikiltu decreased by 45.7% and 47.5%, respectively, and the total cereal production declined by 35.6%. The average number of cattle bought per house hold per year in Chewaka, 1.15 head, was significantly higher (P=0.000) than the average number of 0.55 head in Bikiltu. The chances of cattle and oxen mortality in Bikiltu were 10 and 6 times (OR= 6.5 and 10.2) more likely than in Chewaka and the chance of abortion in cows in Bikiltu was more than 10 times as compared to Chewaka (OR=10.79). The control operation in chewaka settlement station resulted in rapid growth of livestock and crop production, fast expansion of farmland, improved income from animal sell and increased animal purchasing power.

Dogs with a history of more than three episodes of skin infections in a period of one year were selected for a study on recurrent pyoderma. Oral enrofloxacin along with appropriate simultaneous medication for the underlying associated conditions were chosen as therapy for recurrent pyoderma in dogs. Response to therapy was excellent in all the cases. Improvement was noticed by 12 to 20 days and 20 to 26 days in recurrent superficial and deep pyoderma respectively. Relapse occurred in one dog by 45 days due to re-introduction of allergic food. Enrofloxacin proved to be an effective, safe and convenient antibiotic for the treatment of recurrent pyoderma in dogs.

Charlotte E. Ellis | Vuyokazi E. Mareledwane | Roy Williams | David B. Wallace | Phelix A.O. Majiwa
Rift Valley fever virus (RVFV) infects humans and livestock, causing haemorrhaging andabortions in animals. Three major RVF epizootics have occurred in South Africa since the1950s and the outbreak in 2010 had a mortality rate of 10.7% in humans. Accurate and earlydetection is therefore essential for management of this zoonotic disease. Enzyme-linkedimmunosorbent assays (ELISAs) have been developed for the detection of either IgM or IgGantibodies to RVFV in animal sera. In this study, data are presented on the validation of adouble-antigen ELISA for the simultaneous detection of both classes of antibodies to RVFV ina single test. ELISA plates were coated with a recombinant nucleoprotein. The nucleoprotein,conjugated to horseradish peroxidase, was used as the detecting reagent. A total of 534 serafrom sheep and cattle were used in the validation. The sheep sera were collected during a RVFpathogenesis study at the Agricultural Research Council (ARC) – Onderstepoort VeterinaryInstitute and the cattle sera were collected during an outbreak of RVF in 2008 at the ARC –Animal Production Institute in Irene, Pretoria. The ELISA had a diagnostic sensitivity of 98.4%and a specificity of 100% when compared to a commercial cELISA. This convenient and fastassay is suitable for use in serological surveys or monitoring immune responses in vaccinatedanimals.

The paradigmatic, fatal and devastating ailment called avian influenza or bird flu is a highly contagious viral disease caused by type A influenza virus, It primarily affects the respiratory, digestive and/or nervous system of chickens, turkeys, guinea fowls and other avian species and less commonly pigs and other species of mammals including human. In India, The first pandemic outbreak of Avian Influenza was reported during 2006. In this study, we selected an isolate of high pathogenic avian influenza (A/Ck/Jalgaon/India/12419/2006) H5N1 virus and propagated in chicken embryo fibroblast. Later this virus was adopted and propagated in Madin-Darby canine kidney cells (MDCK) and Vero cells. Infected non-avian cells with an avian virus shown cytopathic effects like rounding, cytoplasmic elongation, syncytia formation and later stages fluffing from the attached surface. The harvested virus suspension shown increased haemagglutination titre (HA) than viral suspension from chicken embryo fibroblast culture and the presence of virus was confirmed by reverse transcriptase-polymerase chain reaction (RT-PCR). The obtained result reveals that virus had capacity to adopt for the invitro culture and propagate in non avian host cells with higher titre. This infers the chance of virus to cross the host barrier and probable chance of infection in human being.
