Discovery of the Typhoid Bacillus At the beginning of the 19th century, typhoid was defined on the basis of clinical signs and symptoms and pathological (anatomical) changes. In 1880s, the typhoid bacillus was first observed by Eberth in spleen sections and mesenteric lymph nodes from a patient who died from typhoid. In 1896, it was demonstrated that the serum from an animal immunized with the typhoid bacillus agglutinated (clumped) the typhoid bacterial cells, and it was shown that the serum of patients afflicted with typhoid likewise agglutinated the typhoid bacillus.

Chlamydia Psittaci Chlamydia psittaci - also referred to as Psittacosis, Parrot Fever or chlamydiosis. The word Psittacosis comes from the Greek word Psittakos, meaning parrot. Chlamydia are gram negative, spherical, (0.4-0.6 micron diameter), intracellular parasites that people sometimes referred to as "energy parasites" because they use ATP (a crucial energy containing metabolite) produced by the host cell, hence, the term "energy parasites. Incubation periods in caged birds vary from days to weeks and longer. In birds, C. psittaci may manifest itself as an upper respiratory infection with nasal, and or ocular discharge, diarrhea, or a combination of all three. A major concern with C. psittaci is the zoonotic potential of the organism. *C. psittaci is related to Chlamydia trachomatis, the most common human STD, and Chlamydia pneumonia, a cause of human pneumonia.

General Information on Salmonella Salmonellosis is an infection with bacteria called Salmonella. Salmonella germs have been known to cause illness for over 100 years. They were discovered by an American scientist named Salmon, for whom they are named. Most persons infected with Salmonella develop diarrhea, fever, and abdominal cramps 12 to 72 hours after infection. The illness usually lasts 4 to 7 days, and most persons recover without treatment. How Common is Salmonellosis? Every year, approximately 42,000 cases of salmonellosis are reported in the United States. Children are the most likely to get salmonellosis. Are there Long-Term Consequences to a Salmonella Infection? Persons with diarrhea usually recover completely, although it may be several months before their bowel habits are entirely normal.

GmbH - Ornithose Ornithose L'ornithose est une maladie infectieuse qui affecte beaucoup d'espèces d'oiseaux, à l'échelle planétaire. Elle peut être transmise aux humains et à d'autres mammifères. Agents pathogènes: Chlamydia psittaci. Les Chlamydias sont des micro-organismes immobiles qui envahissent, en parasite, les cellules. Symptômes de la maladie: L'ornithose apparaît sous deux formes: - La forme aiguë peut être identifiée chez les jeunes pigeons à partir: des bruits d'halètement, de conjonctivites uni- ou bilatérales et d'entérites muco-aqueuses avec diarrhées. - La forme chronique est plus souvent rencontrée chez les oiseaux adultes qui, dans tous les cas, montrent peu ou pas de signes de maladie. Mise en évidence de la maladie: La maladie peut être mise en évidence chez les pigeons morts par l'examen microscopique d'un prélèvement ou d'une préparation par expression de la rate, du foie, de la conjonctive ou des sacs aériens préalablement colorés selon la méthode de Stamp.

Feed one likely source of salmonella in eggs, federal officials say Are organic cage-free eggs safer? Wright County Egg issues statement mentioning outside vendorsTesting showed contamination in food mill, in manure samplesNew egg rules are the key to prevention, federal officials say The Egg Safety Center has a complete list of recalled eggs, their expiration dates, and brands. Here are safety tips and a list of affected states. (CNN) -- Federal investigators have found salmonella bacteria in chicken feed and in barn and walkway areas at Iowa farms at the center of the nationwide outbreak, officials said. The feed or feed ingredients could have become contaminated after they went through heat treatment that was sufficient to kill salmonella, officials from the Food and Drug Administration told reporters. Produced at a mill at a Wright County Egg Co. facility, the feed was given to pullet chickens at both Wright County Egg and Hillandale Farms, which between them recalled more than a half-billion eggs since the salmonella outbreak.

La chlamydiophilose Mis à jour le Jeudi, 17 Mai 2012 La chlamydophilose : une maladie des oiseaux d'origine bactérienne, de diagnostic difficile qui peut être grave pour l’oiseau et son entourage Qu’est-ce que la chlamydophilose ? La chlamydophilose est une maladie bactérienne des oiseaux dont l’agent responsable est Chlamydophila psittaci. A l’origine, cette maladie a été dénommée psittacose, car on pensait que seuls les Psittacidés transmettaient la maladie. On découvrit plus tard que d’autres espèces pouvaient être atteintes, et le nom devint l’ornithose. Quelle est son épidémiologie ? Réceptivité L'agent responsable : Chlamydophila psittaci L’agent responsable de la chlamydophilose aviaire est une bactérie appelée Chlamydophila psittaci. Il existe une grande diversité de souches de chlamydies plus ou moins virulentes en fonction de leurs caractères antigéniques. Il est possible que d’autres espèces de Chlamydophila (Ch. pneumoniae, Ch. felis, Ch. trachomatis ) puissent se transmettre aux oiseaux..

Salmonella Bareilly and Nchanga Infections Associated with a Raw Scraped Ground Tuna Product - Salmonella Introduction CDC collaborated with public health officials in many states and the U.S. Food and Drug Administration (FDA) to investigate a multistate outbreak of Salmonella Bareilly and Salmonella Nchanga infections associated with an imported frozen raw yellowfin tuna product, known as Nakaochi Scrape, from Moon Marine USA Corporation. Salmonella Bareilly and Salmonella Nchanga are unusual serotypes of Salmonella in the United States. A total of 425 individuals infected with the outbreak strains of Salmonella Bareilly or Salmonella Nchanga were reported from 28 states and the District of Columbia. Four hundred and ten persons infected with the outbreak strain of Salmonella Bareilly were reported from 28 states and the District of Columbia. Among 425 persons for whom information was available, illness onset dates ranged from January 1 to July 7, 2012. This particular outbreak appears to be over.

CAFOS and Salmonella DETECTION OF CHLAMYDIA PSITTACI INFECTION IN PET BIRDS USING A MOLECULAR BASED DIAGNOSTIC ASSAY - by Dr. Robert Dahlhausen DVM,MS & Dr. C. Steven Radabaugh DVM, MS SummaryChlamydia psittaci infection is well established in our pet bird population. Infections range from a clinically inapparent state, with intermittent shedding of the organism, to overt clinical disease and mortality. Establishing a confirmatory diagnosis of infection in the live bird is difficult as no single test can accurately diagnose the disease in all species or at all times. Conventional diagnostic methods have inherent problems in detection (sensitivity & specificity) and interpretation of results which are often equivocal. IntroductionAvian chlamydiosis is an important disease that has historically affected aviculture for decades. Chlamydial InfectionThe elementary body is the infective form of the Chlamydial organism which reproduces by infecting a host cell. The organism has been isolated from over 120 species of birds with infection in parakeets, lovebirds, cockatiels, amazon parrots, and macaws being the most prevalent. Materials and Methods TABLE 1.

Salmonella Salmonella /ˌsælməˈnɛlə/ is a genus of rod-shaped, Gram-negative bacteria. There are only two species of Salmonella, Salmonella bongori and Salmonella enterica, of which there are around six subspecies and innumerable serovars. The genus belongs to the same family as Escherichia, which includes the species E.coli. Salmonellae are found worldwide in both cold-blooded and warm-blooded animals, and in the environment. Features[edit] Salmonella are non-spore-forming, predominantly motile enterobacteria with diameters around 0.8 to 1.5 µm, lengths from 2 to 5 µm, and peritrichous flagella, (flagella that are all around the cell body). History[edit] The genus Salmonella was named after Daniel Elmer Salmon, an American veterinary pathologist. Detection, culture and growth conditions[edit] Most subspecies of Salmonella produce hydrogen sulfide,[4] which can readily be detected by growing them on media containing ferrous sulfate, such as is used in the triple sugar iron test (TSI).
