Livestock Good sanitation and the prevention of contact with contaminated environments or infected wildlife levitra plus 400mg otc, particularly rodents generic 400mg levitra plus with amex, can decrease the risk of infection generic levitra plus 400mg fast delivery. Fence stream banks and watering holes purchase 400 mg levitra plus, to limit access by livestock to water bodies contaminated by urine from infected animals, and to reduce contamination of water courses. Provide clean drinking water in separate watering tanks located away from potentially contaminated water sources. Chlorinate contained drinking water sources and prevent urine contamination of food and water where possible. Do not chlorinate natural water bodies as this will have an adverse effect on the wetland ecosystem. Keep livestock wastes away from pastures, animal housing and feeding sites and away from water courses in so far as possible. Replacement stock should be selected from herds that have tested negative for leptospirosis. Animals not known to be Leptospira-free should be quarantined for four weeks and tested before being added to the herd. Vaccination of pigs, cattle and dogs may prevent infection caused by certain bacterial strains and prevent abortions in cattle. Note that vaccination of animals may not completely prevent infection and the animals may remain carriers of the bacteria. Antibiotics may be used to treat infections caused by certain bacterial strains and may prevent disease and abortion in cattle. Wildlife Sporadic cases occur in free-ranging wildlife, but are likely to go unnoticed. Rodent control from a pest perspective may be important in this context, although prevention of contamination of feed, bedding and water, and water treatment, as discussed, may be more appropriate. Protect food from sources of infection, particularly rodents, and always cook food thoroughly. Have disinfection facilities for hands, footwear, clothing, equipment and vehicles/trailers on entering or leaving areas with livestock and after contact with animals. Wash hands thoroughly with soap and warm water: - before preparing and eating food - after contact with potentially contaminated water sources - after contact with animals - after working outside. Wear protective clothing especially if working in or near water or with animals: - wear protective clothing and footwear, either disposable or easily disinfected re-usable clothes (e. Look out for symptoms following such activities and seek early treatment if needed. Vaccination: annual vaccination may provide protection against some bacterial strains, particularly for those working in or close to water and with animals. Antibiotic treatment: preventative use can be considered for short periods, particularly for those in high risk groups, and is most effective if given early in the infection. Effect on livestock Mortality may be high in calves and young or weak piglets but low in adults, many of which will have mild symptoms or show no signs of infection at all. Those working in or close to contaminated water are most likely to develop infection. Economic importance There is potential for significant economic losses to the livestock industry due to illness, abortions and reduced milk yield of infected animals and likely trade restrictions imposed during and after an outbreak. Illness in humans can result in significant economic losses due to the time lost from normal activities. Oysters are subject to a number of diseases which can impact the local population and reduce harvests in a commercial setup. Oysters that are produced in areas contaminated with biotoxins or heavy metals could potentially cause health concerns for humans. Humans are also at risk when consuming raw oysters which contain levels of Vibrio (Gram- negative bacteria). Examples of major oyster diseases and their causal protozoan agents are: bonamiosis (Bonamia exitiosa, B. Species affected Farmed and wild oysters worldwide are affected by diseases and those species known to be susceptible are: Scientific name Common name Ostrea angasi Australian mud oyster O. Environment The causative pathogens live in aquatic environments in both tropical and temperate zones. High temperatures and salinities favour the proliferation of some of the pathogens.
