Coxiella burnetii, is a Gram-negative obligate intracellular bacterium, adapted to thrive within the phagolysosome of the phagocyte. Humans become infected primarily by inhaling aerosols that are contaminated with C. burnetii. Ingestion (particularly drinking raw milk) and person-to-person transmission are minor routes. Animals shed the bacterium in urine and feces, and in very high concentrations in birth by-products. The bacterium persists in the environment in a resistant spore-like form which may become airborne and transported long distances by the wind.

Rana, Joint Director, Zoonosis Division Dr. Mala Chhabra, Deputy Director, Zoonosis Division FOREWORD Several zoonotic diseases are major public health problems not only in India but also in different parts of the world. Some of them have been plaguing mankind from time immemorial and some have emerged as major problems in recent times. Diseases like plague, Japanese encephalitis, leishmaniasis, rabies, leptospirosis and dengue fever etc. have been major public health concerns in India and are considered important because of large human morbidity and mortality from these diseases. During 1994 India had an outbreak of plague in man in Surat (Gujarat) and Beed (Maharashtra) after a lapse of around 3 decades. Again after 8 years in 2002, an outbreak of pneumonic plague occurred in Himachal Pradesh followed by outbreak of bubonic plague in 2004 in Uttaranchal. Japanese encephalitis has emerged as a major problem in several states and every year several outbreaks of Japanese encephalitis are reported from different parts of the country. Resurgence of Kala-azar in mid seventies in Bihar, West Bengal and Jharkhand still continues to be a major public health concern. Efforts are being made to initiate kala-azar elimination programme by the year 2010. Rabies continues to be an important killer in the country.

    CDC’s AMD Program AMD Projects Innovate • Transform • Protect CDC’s Advanced Molecular Detection (AMD) program fosters scientific innovation in genomic sequencing, epidemiology, and bioinformatics to transform public health and protect people from disease threats. AMD Project: Deadly Disease Databases Whole genome analysis and database development for anthrax (Bacillus anthracis), melioidosis (Burkholderia pseudomallei), and Brucellosis (Brucella spp.) Epidemiologists and forensic professionals can use whole genome sequencing – a way of determining an organism’s complete, detailed genome – and large databases to determine the source of dangerous germs. Having a large, accessible collection of disease pathogens could help scientists quickly find out if a certain illness is naturally occurring or the result of bioterrorism. CDC is establishing a public database where scientists from around the world can share information about these potentially deadly CDC is establishing public databases so that diseases. CDC scientists have begun sequencing the organisms that scientists from around the world can share information about deadly diseases like cause anthrax (Bacillus anthracis), brucellosis (Brucella spp.), and anthrax, brucellosis, and melioidosis. melioidosis (Burkholderia pseudomallei), three pathogens that could occur naturally or as the result of bioterrorism. Current methods of determining the genetic structure of these organisms are not standardized and sometimes not effective. Using whole genome sequencing for these pathogens will allow scientists www.cdc.gov/amd Updated: May 2017 to accurately and quickly find the geographic origin of the isolates and will improve overall knowledge and understanding of them.

The diseases that are reportable to state and local health departments differ from state to state; however, certain diseases are considered nationally notifiable diseases. The list of nationally notifiable diseases is updated annually. The Centers for Disease Control and Prevention (CDC), in collaboration with the Council of State and Territorial Epidemiologists (CSTE), publishes case definitions for public health surveillance for the nationally notifiable diseases. These case definitions provide uniform criteria for reporting cases and are case specific. The case status for most diseases is determined as follows: • A confirmed case is one in which the clinical case description is met and the laboratory confirmation requirement is met. A case may also be considered confirmed if it is linked to a laboratory-confirmed case. Certain diseases may not include laboratory findings as testing is not available. • A probable case is one in which the clinical case description is met and there is supportive or presumptive laboratory results consistent with the diagnosis but, it does not meet the laboratory confirmed criteria. • A suspect case is one in which the clinical case description is met. • A revoked case is one in which neither the suspect, probable, nor confirmed case definition is met. A significant amount of information gathering must be collected for many diseases before a case classification is final.

After blood cultures came back positive for Salmonella Salmonella typhi typhi, the patient was started on strong antibiotics and eventually stabilized and was released Enteric fever home. This case represents an atypical presentation and the further management of Salmonella Salmonella paratyphi typhi infection in the primary care setting. The patient presented to the emergency room as a recent traveler to America from India, where Salmonella typhi is considered endemic. A few hours from initial presentation, the patient deteriorated and was admitted to the ICU, where further workup was done, including imaging, cultures, and labs. After blood cultures came up positive for non-lactose fermenting gram-negative rods, later identified to be the Salmonella typhi organism, the patient was put on tobramycin and levofloxacin for 10 days; he eventually stabilized and was discharged home.

  • 61% of All Human Pathogens Are Zoonotic (Passed from Animals to Humans), and Many Are Transmitted Through Inhaling Dust Particles Or Contact with Animal Wastes
    Zoonotic Diseases Fast Facts: 61% of all human pathogens are zoonotic (passed from animals to humans), and many are transmitted through inhaling dust particles or contact with animal wastes. Some of the diseases we can get from our pets may be fatal if they go undetected or undiagnosed. All are serious threats to human health, but can usually be avoided by observing a few precautions, the most effective of which is washing your hands after touching animals or their wastes. Regular visits to the veterinarian for prevention, diagnosis, and treatment of zoonotic diseases will help limit disease in your pet.

  • Enteric Infections Due to Campylobacter, Yersinia, Salmonella, and Shigella*
    Bulletin of the World Health Organization, 58 (4): 519-537 (1980) Enteric infections due to Campylobacter, Yersinia, Salmonella, and Shigella* WHO SCIENTIFIC WORKING GROUP1 This report reviews the available information on the clinical features, pathogenesis, bacteriology, and epidemiology ofCampylobacter jejuni and Yersinia enterocolitica, both of which have recently been recognized as important causes of enteric infection. In the fields of salmonellosis and shigellosis, important new epidemiological and relatedfindings that have implications for the control of these infections are described. Priority research activities in each ofthese areas are outlined. Of the organisms discussed in this article, Campylobacter jejuni and Yersinia entero- colitica have only recently been recognized as important causes of enteric infection, and accordingly the available knowledge on these pathogens is reviewed in full. In the better- known fields of salmonellosis (including typhoid fever) and shigellosis, the review is limited to new and important information that has implications for their control.! REVIEW OF RECENT KNOWLEDGE Campylobacterjejuni In the last few years, C.jejuni (previously called 'related vibrios') has emerged as an important cause of acute diarrhoeal disease. Although this organism was suspected of being a cause ofacute enteritis in man as early as 1954, it was not until 1972, in Belgium, that it was first shown to be a relatively common cause of diarrhoea. Since then, workers in Australia, Canada, Netherlands, Sweden, United Kingdom, and the United States of America have reported its isolation from 5-14% of diarrhoea cases and less than 1 % of asymptomatic persons. Most of the information given below is based on conclusions drawn from these studies in developed countries.
