Relapse case: a patient declared cured or treatment completed of any but who is found to be smear positive. Treatment failure: a patient who, while on treatment remains or becomes smear positive at the end of fifth month or later after commencing treatment. Defaulter: a patient who has been on treatment for at least four weeks and whose treatment has been interrupted for more than eight consecutive weeks or cumulative period of more than 12 weeks. Treatment after default: A patient who had previously been recorded as treatment and returns to the health service with smear positive sputum. Cured: a patient who is smear negative one month prior to completion of treatment and at least at one previous occasion. Treatment completed: a patient who has completed treatment but in whom smear result is not available at least on two occasions. In re- treatment regimen five drugs are given during the first two Months, four drugs during the third month of the intensive phase and three drugs are given in the continuation phase for five months. Clinical assessment Disappearance of symptoms like; cough, fever, sweating, and loss of appetite. Laboratory assessment If the direct smear is negative at the end of eight weeks, the continuation phase can be started. After this additional four weeks of intensive treatment, continuation phase must be started regardless of the result of sputum examination. If in the continuation phase of treatment the result of sputum at the end of fifth month is negative, the patient is allowed to continue with the same treatment. If the result of sputum is positive at five months or more after the start of chemotherapy, the patient is declared a treatment failure and must start a full course with re-treatment.

Hold the syringe close and flat to the skin so that the tip of the needle touches the skin as it is introduced with the bevel up. First inspect the area for the presence of induration by slightly palpating across the injection site from the area of normal skin to the margin of induration. Then, the horizontal (transverse) diameter of the induration (not erythema) is measured in millimeter at its widest part i. Measure it with a transparent ruler of 10 cm in length and report the result to the medical officer. Major side effects: the following major side effects may occur and require immediate attention. A small red tender swelling about 10 mm appears around the place of immunization after about two-three weeks. What to do for abnormal reaction: Sometimes there is severe local inflammation, or a deeper abscess or the lymphatic glands near the elbow or in the axilla swell. This may be because the needle was not sterile, deep injection under the skin given by mistake, or large dose of vaccine given. If a very large ulcer forms or if the lymphatic glands swell refer the child to the medical officer for advice. Read the task analysis of the different categories of the health center team on unit 4. She usually serves coffee in the mornings and afternoons in her small and warm tukul where five to six people including herself enjoy the coffee drinking. Amina usually sits beside the children telling them traditional folktales which they attentively listen. Nevertheless, these days her stories are frequently interrupted by the chest pain and rigorous coughing while trying to tell the children the stories. At times, she spits on to the ash near the fire place and often observes her sputum containing blood.

These procedures include the growth of bacteria in liquid culture, the growth of large numbers of bacteria. Ideally, items of equipment which might generate aerosols should be contained within a purposebuilt cabinet. Centrifuges may cause dangerous aerosols, especially when tubes containing virulent bacteria break. Glass tubes should not be used for virulent materials, instead polycarbonate tubes with tightly-fitting screw-capped lids and rubber O-rings are recommended. When centrifuges are located outside a biosafety cabinet, the centrifuge rotors should incorporate some form of seal that allows the rotor to be removed and opened only within a safety cabinet. Additionally, during centrifugation procedures access to the laboratory should be limited only to individuals wearing some form of respiratory protection such as a respirator. Respiratory protection should only be removed when the rotor has been opened, and the integrity of the centrifuge tubes has been established. The bacterium does not form resistant structures and is relatively sensitive to all standard inactivation procedures. The bacterium is sensitive to hypochlorite and other commonly-used chemical decontaminants. Typically, heating to 60 °C for 1 h will inactivate bacteria in suspension, but the precise conditions for complete killing need to be ascertained in the laboratory. The tem perature and time required for bacterial killing will depend not only on the strain being used but also on the density of the cell suspension and the suspending medium. Care must be tak en with this type of low-temperature inactivation to ensure the statistically-significant pos sibility of killing all bacteria. Therefore it is necessary to first construct a killing curve which will inform the researcher of the conditions required for bacterial killing. Baseline blood samples should be taken before any work commences and staff should carry an "at risk" card indicating that in the event of a febrile illness, accidental exposure to F. However, the isolation of the individual is not necessary since human-to-human transmission of the disease has not been reported. For details of chemotherapeutic regimes for the treatment of tularaemia see chapter 5. This vaccine would also have a utility for the protection of researchers who are working with highly-virulent strains of F. It is also unavailable in Europe and most other parts of the world, but a live attenuated vaccine is still in use some parts of the former Soviet Union 43 wHo guidelines on tulArAemiA where it has been used to immunize millions of people against tularaemia (Sjцstedt, Tдrnvik & Sandstrцm, 1996). Of the animal species which have been evaluated as models of disease, the non-human primates and rabbits appear to mimic human disease most accurately. In contrast, mice appear to be uniformly susceptible to disease caused by strains belonging to all subspecies, including F. This model of disease is valuable because protective immune responses can be induced by the delivery of this strain intradermally or by scarification while mechanisms of virulence can be investigated when the strain is given by the intraperitoneal or intravenous routes. There is also good reason to believe that these findings reflect the nature of the protective responses in humans; previous studies have shown that the passive transfer of immune serum provides only very limited protection against tularaemia. In addition, different batches of the vaccine show different immunogenicity, a property ascribed to the different proportions of so-called blue and grey colony types (Eigelsbach & Downs, 1961). There is some evidence that the vaccine is effective when given by the airborne and oral routes of delivery (Saslaw et al. All of the control subjects developed tularaemia and at the earliest indication of disease were treated with streptomycin or tetracycline. The majority of vaccinees challenged with up to 2000 organisms escaped major clinical illness. A study published by Burke in 1977 reported the incidence of laboratory-acquired tularaemia before (1950­1959) and after (1960­1969) routine immunization of workers. The incidence of ulceroglandular tularaemia was unchanged but the clinical signs and symptoms of this form of the disease were moderated in vaccinated individuals.

Arenavirus particles range in morphology from highly pleomorphic as shown in this field to mainly spherical. Bunyaviral particles are roughly spherical and range in diameter from 90 to 120 nm. Flaviviral particles are essentially isometric and consistent in size, ranging from 40 to 50 nm in diameter. Filoviral particles are mostly filamentous and vary in length up to 14,000 nm with a uniform diameter of 80 nm. Other forms of filoviral particles include U-shaped, "6"-shaped, or circular configurations; branching of filamentous particles can also occur. Hantaviruses and nairoviruses use negative-sense coding strategies, whereas phleboviruses use ambisense coding strategies. In infected cells, the prM protein is cleaved by furin to form a small, nonglycosylated membrane protein (M) and an N-terminal "pr" segment that is secreted. The exact nature of the disease depends on the viral virulence and strain characteristics, routes of exposure, dose, and host factors. Conjunctival injection and subconjunctival hemorrhage, as seen in this Lassa fever patient, are sometimes associated with viral hemorrhagic fever infection. Ebola-Zaire infections greatly exceeds the incubation period for injections or needle stick accidents.

Ebola and Marburg outbreaks in sub-Saharan Africa have had particularly high case-fatality rates, ranging from 50% to 90%. There is a prodrome period that may include a high fever, headache, malaise, myalgias, arthralgia, abdominal pain, nausea, and diarrhea, which usually lasts less than a week. For Lassa fever patients, hemorrhagic manifestations are not pronounced, and neurological complications are infrequent, develop late, and manifest only in the most severely ill group. This occurrence has practical significance in that renal dialysis can be started with relative safety.

Among the flaviviruses, yellow fever virus is hepatotropic; black vomit caused by hematemesis has been associated with this disease. Patients with yellow fever develop clinical jaundice and die with something comparable to hepatorenal syndrome. Characteristic petechial rash of the abdomen and inguinal region of a cynomolgus monkey infected with Marburg virus. Some patients have anemia, and others have hemoconcentration; most have elevated liverassociated enzymes. Prothrombin time, activated partial thromboplastin time, and bleeding time are often prolonged. Urine tests may show proteinuria and hematuria; patients with renal failure may have oliguria or azotemia. At these sites, the virus infects tissue macrophages (including Kupffer cells) and dendritic cells. Soluble factors released from virus-infected monocytes and macrophages act locally and systemically. Release of chemokines from these virus-infected cells recruits additional macrophages to sites of infection, making more target cells available for viral exploitation and further amplifying the dysregulated host response. Although none of these viruses infects lymphocytes, the rapid loss of these cells by apoptosis is a prominent feature of disease. For example, viral infection of dendritic cells impairs their function by interfering with the upregulation of costimulatory molecules, which are important in providing rescue signals to T lymphocytes. At the same time, reduced synthesis of albumin by hepatocytes results in a reduced plasma osmotic pressure and contributes to edema.

Syndromes

• Anti-CCP antibody test
• Flu vaccine prevents pneumonia and other problems caused by the influenza virus. It must be given each year to protect against new virus strains.
• Convulsions
• Chronic inflammatory disease
• Weakened immune system
• Problems concentrating or thinking

First is to start treatment of the infected animal as soon as possible in order to stop shedding of the organism into the environment. Additionally the facility should examine its ventilation, hygiene and sanitation protocols in order to increase the dilution of bacteria and reduce their aerosolization. Current recommendations using a one or two-phase protocol recommend 12 months of treatment. Treatment length may be affected by the antibiotics that can be successfully administered to the elephant. Using combination protocols with less frequent dosing or antibiotics of lesser known effectiveness may extend the treatment period for 15 to 18 months. How often should an elephant be tested while it is being treated for tuberculosis? Page 10 of 58 Frequently Asked Questions for State and Regulatory Veterinarians Because elephants may travel across state lines for facility transfers, breeding or exhibitions, questions about Mtb in elephants have often arisen from the regulatory sector. The veterinarian writing the health certificate should list to which category each elephant on the certificate belongs (Category A, B, or C). Elephants in Category A have had no known exposure to culture positive animals within a 5 year period. Category C elephants would only travel if necessary for medical care Are Mtb testing recommendations the same for all elephants? Category C elephants receive considerably more testing which is described elsewhere. The serologic tests are not confirmatory for Mtb and should not be used as a solo test for regulatory purposes. Elephants are traveling to a livestock arena or venue in my state; what precautions should be taken to prevent the transmission of Mtb to other livestock? Travelling elephants (both Categories A and B) are routinely trunk washed and negative by culture. There has been no documented case of Mtb transmission from elephants to livestock. This aspect of the preventative medicine program should be reviewed and updated annually by the attending veterinarian. Risk assessments A standard risk assessment for Mtb infection in an elephant or its herd includes the following: 1. Complete history of the elephant and its herdmates including: Signalment: Mtb is primarily a disease of Asian elephants although several cases were identified in African elephants in Europe and one unconfirmed by culture report in a free ranging African elephant (Obanda 2013). Travel and housing history of elephant and herdmates with regard to Mtb exposure Current health problems (including age-related diseases) Diagnostic procedures for which the elephant is trained. Husbandry practices that could increase risk of transmission of Mtb Barn ventilation Barn cleaning procedures, i. Mtb diagnostic test results Trunk wash results over 5 years Other samples submitted for Mtb culture such as semen, milk, feces, biopsies Serological test results Page 12 of 58 B. Testing for Mtb in Elephants: Ante mortem and Postmortem Diagnostic Options Diagnostic tests for Mtb can be applied to elephants ante mortem or postmortem. Ante mortem testing can be done for surveillance, when there is concern or confirmation of disease, or for regulatory purposes, i. Two general groups of tests are available: Direct tests identify the actual Mtb organism. Culture is the only definitive means of diagnosing infections, although negative results cannot be construed as definitively being equivalent to absence of infection. Tests other than culture can be used when agreed to by parties of origin and destination, but should not be used as sole test for regulatory purposes. A positive culture result indicates an elephant is infected but a negative result does not rule out infection. Where available (rare) pulmonary fluid wash or biopsies collected via endoscopy are likely superior to trunk washes due to reduced contamination and the opportunity to collect samples likely closer to or at the site of lesions.
