Actinomyces species (Actinomycoses) Actinomyces bovis causes granulomatous infections in cattle; however, this species has never been proven as a human pathogen and earlier reports of human A. bovis infections most probably were due to A. israelii (5, 47).Ten additional Actinobacillus species have as yet solely been isolated from animal sources.he etiology of human actinomycoses is complex in two respects: the principal etiological agents of the disease do not belong to a single species, but to a variety of different members of the genera Actinomyces, Propionibacterium, and Bifidobacterium.

Animal Industry Division What is Johne’s disease? Johne’s disease (pronounced “YO – knees”) is an incurable, contagious bacterial infection which primarily affects the intestinal tract of cattle and other ruminants such as sheep, goats, deer, and elk. Typical animals have a normal or increased appetite even as they steadily lose weight.

A Closer Look at Mycoplasma-Related Lameness The confusion is understandable when we recognize that there are several quite different Mycoplasma species that very commonly infect pigs. Additionally, Mycoplasma infections do not always cause clinical disease. Mycoplasma are bacteria-like organisms that have a long history causing disease in swine. The most well-known and most economically important is Mycoplasma hyopneumoniae, a very common cause of pneumonia.

- FEBRUARY 2007 PRIMEFACT 451 (REPLACES AGFACT A2.9.7) Vibriosis of cattle Dr Steven Hum Senior Veterinary Officer, Research Operations, Menangle Introduction Bovine vibriosis (also known as Bovine Venereal Campylobacteriosis, or BVC), is one of the most important infectious venereal diseases of cattle in Australia.hat causes vibriosis Vibriosis is caused by the bacterium Campylobacter fetus and is spread by infected bulls when they mate susceptible cows and heifers. Immunity against vibriosis in bulls is not developed easily and they can be infected for a long time without showing any signs of illness.

Enterotoxemia: The overeating disease in sheep and goats Enterotoxemia is a frequently severe disease of sheep and goats of all ages. It is caused by two strains of bacteria called Clostridium perfringens — the strains are termed types C and D. These bacteria are normally found in low numbers in the gastrointestinal tract of all sheep and goats.t is caused by two strains of bacteria called Clostridium perfringens — the strains are termed types C and D.

- Excess underlying tissue was removed from the buccal mucosa by dissection with a scalpel and mounted between two halves of Sweetana-Grass diffusion chamber clamps (Ceschel et al. Our detection of MCPyV DNA in 2 buccal mucosa swabs is in line with recent reports of the widespread viral DNA in the human body (12,13,15).

- Actinomycosis is an infectious bacterial disease caused by Actinomyces species such as Actinomyces israelii or A. gerencseriae.It can also be caused by Propionibacterium propionicus, and the condition is likely to be polymicrobial aerobic anaerobic infection.ctinomyces bacteria are generally sensitive to penicillin, which is frequently used to treat actinomycosis. In cases of penicillin allergy, doxycyclin is used. Sulfonamides such as sulfamethoxazole may be used as an alternative regimen at a total daily dosage of 2-4 grams.

Endoparasites Disease can result from the migration of large numbers of immature flukes through the liver, or from the presence of adult flukes in the bile ducts, or both. Liver fluke disease affects both cattle and sheep and is an all year round problem. Sheep are more prone to the acute form of the disease and this can be fatal. Cattle typically suffer from chronic disease, rather than the acute form and fatalities are not so common with this type of infection.

Veterinary Division - Animal Health Programs What causes Anaplasmosis in cattle? Anaplasmosis is caused by the organism Anaplasma marginale. This organism is a member of the Rickettsia family of disease-causing agents. Anaplasmosis is spread by the bite of the common horsefly, other biting insects, or any instrument which can transmit blood.

- Arthritis: The incidence of Mycoplasma arthritis is increased in cattle herds with enzootic Mycoplasma mastitis and/or pneumonia, since Mycoplasma arthritis occurs commonly secondary to bovine affected with Mycoplasma pneumonia or mastitis due to hematogenous spread. Oral infection of calves from dams with Mycoplasma mastitis may also occur. ...

C ommon and important diseases of cattle Ticks can cause severe damage to cattle, particularly around the udder and ears. The wounds will often get infected with bacteria and might be attacked by flies. Some ticks cause greater damage than others, such as the ones which infect cattle with heartwater. Prevention is by tick control.

Featured Bovine / Cattle diseases In cattle and goats, the infection is usually asymptomatic. When there are signs in cattle, the most common are hyperthermia, abortion towards the end of gestation (in the eighth month), edema (of the udders, teats, vulva, and hocks), and erythema (mucosa, teats, and udders).

Mycoplasma hyosynoviaeynoviae is a small fragile bacteria-like organism that is widespread within pig populations and is spread easily in infected pigs by aerosol and by transfer of faeces. It is possible that it can spread on the wind between farms.

Acanthamoeba species Acanthamoeba, Balamuthia, and Naegleria infect the central nervous system (CNS) of humans and other animals. Acanthamoeba and Balamuthia cause chronic granulomatous amebic encephalitis whereas N. fowleri causes an acute, fulminant primary amebic meningoencephalitis.Acanthamoeba and Balamuthia also cause cutaneous infection in humans. Additionally, Acanthamoeba causes infection of the eye, Acanthamoeba keratitis.Infections also occur naturally in a variety of animals, including gorillas, monkeys, cattle, sheep, dogs, turkeys and toucans (23, 24, 41).canthamoeba has been detected in the CSF of a patient without CNS disease and the authors speculate that the amebae apparently entered the CSF from the nasopharynx through a fistula (31). Acanthamoeba DNA has also been found in the CSF (46).

Zoonotic Diseases of Cattle Zoonotic diseases may be acquired or spread in a variety of ways: through the air (aerosol), by direct contact, by contact with an inanimate object that harbors the disease (fomite transmission), by oral ingestion, and by insect transmission.eptospirosis is a bacterial disease caused by Leptospira interrogans that can occur in a large number of animals, including cattle, sheep, goats, pigs, horses, and dogs. Leptospirosis is spread through the urine of infected animals and can survive in water and soil for months.

Mycoplasma in Beef Cattle Mycoplasma bovis can, by itself, cause respiratory disease. However, the disease most often occurs when an initial stressor causes calves to develop traditional Bovine Respiratory Disease Complex (BRDC or shipping fever), and Mycoplasmosis develops seven to 14 days later.

Blackleg in Cattle Still Problem After Thousands of Years Blackleg seldom affects cattle older than 2 years of age, most likely due to immunity induced by vaccines or natural exposure. However, sporadic cases do occur in cattle older than 2 years and are often associated with the reuse of needles for multiple injections.Blackleg can also be a problem in cattle less than 4 months old that do not receive adequate passive immunity through colostrum.owever, sporadic cases do occur in cattle older than 2 years and are often associated with the reuse of needles for multiple injections.
