Brucellosis is a highly contagious zoonosis caused by ingestion of unpasteurized milk or undercooked meat from infected animals, or close contact with their secretions. It is also known as undulant fever, Malta fever, and Mediterranean fever.
The Brucellaceae are a family of the Gram-negative Rhizobiales. They are named after Sir David Bruce, a Scottish microbiologist. They are aerobic chemoorganotrophes. The family comprises pathogen and soil bacteria
Brucella is a genus of Gram-negative bacteria, named after David Bruce (1855–1931). They are small, nonencapsulated, nonmotile, facultatively intracellular coccobacilli.
Brucella melitensis is a Gram-negative coccobacillus bacterium from the Brucellaceae family. The bacterium causes ovine brucellosis, along with Brucella ovis. It affects primarily sheep and goats, but cases have also been observed in cattle, yaks, water buffalo, Bactrian and dromedary camels, alpacas, dogs, horses and pigs. Humans can become infected if they have contact with an infected animal or its byproducts. Animals acquire B. melitensis by venereal transmission and contact with the placenta, fetus, fetal fluids, and vaginal discharges from infected animals. The organism is found in blood, urine, milk, and semen. It is zoonotic, unlike B. ovis, causing Malta fever or localized brucellosis in humans.
Brucella suis is a bacterium that causes swine brucellosis, a zoonosis that affects pigs. The disease typically causes chronic inflammatory lesions in the reproductive organs of susceptible animals or orchitis, and may even affect joints and other organs. The most common symptom is abortion in pregnant susceptible sows at any stage of gestation. Other manifestations are temporary or permanent sterility, lameness, posterior paralysis, spondylitis, and abscess formation. It is transmitted mainly by ingestion of infected tissues or fluids, semen during breeding, and suckling infected animals.
A coccobacillus, or bacilluscocco, is a type of bacterium with a shape intermediate between cocci and bacilli. Coccobacilli, then, are very short rods which may be mistaken for cocci.
Brucella abortus is a Gram-negative alpha-proteobacterium in the family Brucellaceae and is one of the causative agents of brucellosis. The rod-shaped pathogen is classified under the domain Bacteria. The prokaryotic B. abortus is non-spore-forming, non-motile and aerobic.
Columnaris (also referred to as cottonmouth) is a symptom of disease in fish which results from an infection caused by the Gram-negative, aerobic, rod-shaped bacterium Flavobacterium columnare. It was previously known as Bacillus columnaris, Chondrococcus columnaris, Cytophaga columnaris and Flexibacter columnaris. The bacteria are ubiquitous in fresh water, and cultured fish reared in ponds or raceways are the primary concern – with disease most prevalent in air temperatures above 12–14 °C. It is often mistaken for a fungal infection. The disease is highly contagious and the outcome is often fatal. It is not zoonotic.
Brucella canis is a gram-negative proteobacterium in the family Brucellaceae that causes brucellosis in dogs and other canids. B. canis is rod-shaped or a coccus, and is oxidase, catalase, and urease positive. The species was firstly described in United States in 1966 where mass abortions of beagles were documented. The disease is characterized by epididymitis and orchitis in male dogs, endometritis, placentitis, and abortions in females, and often presents as infertility in both sexes. Other symptoms such as inflammation in the eyes and axial and appendicular skeleton; lymphadenopathy and splenomegaly, are less common. Humans can be also infected, but occurrences are rare. Although there has been an increase in the international movement of dogs, Brucella canis is still very uncommon.
The California Red is a breed of domestic sheep developed in the United States.
Actinobacillosis is a zoonotic disease caused by Actinobacillus.
The M33 cluster bomb, also known as the (M33) Brucella cluster bomb, was a U.S. biological cluster bomb developed in the early 1950s and deployed in 1952. It was the first standardized biological weapon in the U.S. arsenal.
Infectious pancreatic necrosis (IPN) is a severe viral disease of salmonid fish. It is caused by infectious pancreatic necrosis virus, which is a member of the Birnaviridae family. This disease mainly affects young salmonids, such as trout or salmon, of less than six months, although adult fish may carry the virus without showing symptoms. Resistance to infection develops more rapidly in warmer water. It is highly contagious and found worldwide, but some regions have managed to eradicate or greatly reduce the incidence of disease. The disease is normally spread horizontally via infected water, but spread also occurs vertically. It is unable to infect mammals.
"Playing with Fire" is a song recorded by Romanian singer Paula Seling and Romanian-Norwegian performer Ovidiu Cernăuțeanu for their 2010 collaborative album of the same name. It was released as a CD single in 2010 by TVR, TMC and AXR labels. Partly influenced by opera music, the track was written by Ovi and produced by Simen M. Eriksrud. The lyrics of "Playing with Fire" portray a fight between a male and a female, with a reviewer speculating that it revolved around arson, a crime of intentionally, deliberately and maliciously setting fire to buildings or other properties with the intent to cause damage.
Bovine gammaherpesvirus 4 (BoHV-4) is a member of the Herpesviridae family. It is part of the subfamily Gammaherpesvirinae and genus Rhadinovirus. Infection is normally sub-clinical but can cause reproductive disease in cattle such as endometritis, vulvovaginitis and mastitis. Transmission is both vertical and horizontal. It can also be indirectly spread by fomites. Distribution is worldwide and the virus infects a range of ruminants, including bison, buffalo, sheep and goats.
Ungulate bocaparvovirus 1, formerly Bovine parvovirus (BPV), also known as Haemadsorbing Enteric Virus, is a member of the parvivirus group, with three significant sub-species: BPV1, 2 and 3. BPV most commonly causes diarrhoea in neonatal calves and respiratory and reproductive disease in adult cattle. The distribution of the virus is worldwide. Transmission is both vertical and horizontal. The virus is very resistant to chemical and physical challenges.
Gastrointestinal campylobacteriosis is caused by Campylobacter jejuni or Campylobacter coli. Although it is a commensal in the gastrointestinal tract of many species, it can cause diarrhea - mainly in young animals. It is most commonly seen in cattle, but may also infect many other species, including humans. Campylobacter is spread horizontally via the fecal-oral route.
Epizootic ulcerative syndrome (EUS), also known as mycotic granulomatosis (MG) or red spot disease (RSD), is a disease caused by the water mould Aphanomyces invadans. It infects many freshwater and brackish fish species in the Asia-Pacific region and Australia. The disease is most commonly seen when there are low temperature and heavy rainfall in tropical and sub-tropical waters.
Inclusion Body Rhinitis, also known as IBR or Cytomegalic Inclusion Disease, is a pig disease caused by Suid betaherpesvirus 2 (SuHV-2), which is a member of the herpesvirus family. It is a notifiable disease that is found worldwide. It is spread both vertically and horizontally and prevalence is high.
Brucella pinnipedialis is a species of bacteria. It causes infections and related diseases primarily in pinnipeds and cetaceans.
