Chicken Pox

Image
Chickenpox, caused by the varicella-zoster virus, presents a classic set of symptoms and requires comprehensive management. The disease's clinical manifestations, treatment objectives, and nursing management are crucial aspects of addressing chickenpox. Expanding on this information can enhance the understanding and knowledge base for healthcare professionals and the general public. Complications and Sequelae of chicken pox  Encephalitis: Chickenpox can lead to encephalitis, an inflammation of the brain. Monitoring for neurological symptoms is crucial, and prompt medical intervention is necessary if such complications arise. Pneumonia: Respiratory complications, including pneumonia, can occur, especially in vulnerable populations. Vigilant respiratory assessment and supportive measures are essential. Congenital Defects: If a pregnant woman contracts chickenpox, there's a risk of congenital defects in the developing fetus. It underscores the importance of preventing exposure ...

Anthrax: Mode of transmission, signs and symptoms of anthrax and types of anthrax-Studsaver

Image
Anthrax: Mode of transmission, signs and symptoms of anthrax and types of anthrax Anthrax is an acute bacteria notifiable infectious disease due to bacillus anthracis acquired through contact with infected animals or their products such as carcass, bones or skin usually by occupational exposure. Or a disease that affect sheep and cattle and may accidentally be inoculated into man especially those who work with hides. It is caused by spore forming organism called Bacillus anthracis. the Incubation period is usually less than one week. It occurs mostly in workers who process hides, wool, agricultural workers and veterinarians who handle infected animals . MODE OF TRANSMISSION OF ANTHRAX By contact with tissues of infected animals Flies and other insects may transmit from animals to man Ingestion of spores on vegetation SIGNS AND SYMPTOMS OF ANTHRAX Itching appears at the  exposed body surface usually the face in two to four days  Lesion frequency appears at the site Headache M...

CLASSIFICATION OF PROTOZOA

Image
   CLASSIFICATION OF PROTOZOA   CLASSIFICATION OF PROTOZOA All protozoal species are assigned to the kingdom Protista in the Whittaker classification. The protozoa are then placed into different groups primarily on the basis of how they move. The groups are called Phyla or Classes. Member of the four major groups is Mastigophora, Sarcodina, Apicomplexa and Ciliophora. CHARACTERISTICS OF PROTOZOA. MOTILITY Protozoa are notable for their ability to move independently, a characteristic found in the majority of species. They usually lack the capability for photosynthesis, although the genus euglena is renowned for motility as well as photosynthesis (and is therefore considered both an alga and a protozoan). Although most protozoa reproduce by asexual methods, sexual reproduction has been observed in several species. Most protozoal species are aerobic, but some anaerobic species have been observed in the human intestine and animal rumen. ENVIRONMENTAL FACTORS AND FOO...

CHARACTERISTICS AND CLASSIFICATION OF FUNGI

Image
  CHARACTERISTICS AND CLASSIFICATION OF FUNGI CHARACTERISTICS AND CLASSIFICATION OF FUNGI. The word fungus comes from the Latin word for mushrooms. Indeed, the familiar mushroom is a reproductive structure used by many types of fungi. However, there are also many fungi species that don’t produce mushrooms at all. Being eukaryotes, a typical fungal cell contains a true nucleus and many membrane-bound organelles. The kingdom Fungi includes an enormous variety of living organisms collectively referred to as Ascomycota, or true Fungi.     While scientists have identified about 100,000 species of fungi, this is only a fraction of the 1.5 million species of fungus probably present on earth. Edible mushrooms, yeasts, black mold, and the producer of the antibiotic penicillin, Penicillium notatum, are all members of the kingdom Fungi, which belongs to the domain Eukarya. Like bacteria, fungi play an essential role in ecosystems because they are decomposers- and participate...

GENERAL CHARACTERISTICS OF RICKETTSIA

Image
  GENERAL CHARACTERISTICS OF RICKETTSIA Rickettsia is a genus of nonmotile, Gram negative, nonspore-forming, highly pleomorphic bacteria that may occur in the forms of cocci, bacilli, or threads.   GENERAL CHARACTERISTICS OF RICKETTSIA Pleomorphic organisms are microorganisms who have the ability to alter their morphology, biological functions or reproductive modes in response to environmental conditions.     The term “rickettsia” has nothing to do with rickets (which is a deficiency disease resulting from lack of vitamin D): the bacterial genus Rickettsia was named after Howard Taylor Ricketts, in honor of his pioneering work on tick-borne spotted fever.   The rickettsiae are a diverse collection of obligately intracellular Gram-negative bacteria found in ticks, lice, fleas, mites, chiggers, and mammals. These zoonotic pathogens cause infections that disseminate in the blood to many organs.     Clinical Manifestations of Ricketts...

THE TYPES OF IMMUNITY

Image
THE TYPES OF IMMUNITY: The immune system is a complex network of defense mechanisms that protects the body from harmful invaders. It can be broadly categorized into two main components: innate (nonspecific) immunity and adaptive (specific) immunity. These two systems work in concert to defend the body against a wide range of threats, from pathogens to toxins. Innate Immunity:   Innate immunity, also known as nonspecific immunity, is the first line of defense against invading pathogens. It consists of immediate defense mechanisms that are present in a host from birth and do not require prior exposure to specific antigens. Innate immunity is designed to react and eliminate any antigen it encounters. This is the immunity one is born with and provides rapid protection against a wide range of threats. types of immunity Components of Innate Immunity: 1. Physical barriers: These include the skin, gut lining, lung cilia, and other structural elements that prevent pathogens from enter...

SPECIMEN COLLECTION AND TRANSPORT

SPECIMEN COLLECTION AND TRANSPORT:  Specimen collection and handling are among the most critical considerations in patient care because any results the laboratory generates are directly dependent on the quality of the specimen and its condition on arrival in the laboratory. Specimens submitted for microbiological testing require proper handling from the time of collection through all stages of transport, storage, and processing. Issues common to all clinical specimens submitted for microbiological testing include not only proper identification but also collection techniques that maximize recovery of microbial pathogens contamination. For specimens such as sputum and urine, the relative proportions of microorganisms present in vivo must be preserved, or culture results may be misleading. If specimens are handled properly, culture results are easier to interpret, patient care is improved, and costs are potentially decreased. Although most guidelines for specimen handling remain uncha...
