Diphyllobothrium latum and other members of the species are broad fish tapeworms noted from humans. They are parasitic flatworms as examined with the aid of microscopy using a microscope such as brightfield light microscope.
Diphyllobothriasis is the term being called to the disease triggered by broad fish tapeworm contagions. Diphyllobothriasis is typified by diarrhea, abdominal distention, flatulence and sporadic abdominal cramping with commencement approximately ten days after ingestion of raw or inadequately cooked fish as investigated through microscopy under the microscope like the brightfield light microscope. The larva that contaminates individuals, which is a plerocercoid, is oftentimes come across in the viscera of freshwater and marine fishes. Diphyllobothrium latum is at times come upon in the flesh of freshwater fish or fish that are anadromous. Anadromous fishes are those migrating from salt water to fresh water for breeding. Bears and humans are the ultimate or best hosts for this parasitic organism as verified by examinations done through microscopy using a microscope such as brightfield light microscope. Diphyllobothrium latum is a broad, long tapeworm, frequently growing to lengths between one and two meters or three to seven feet and possibly capable of reaching ten meters or thirty-two feet. The closely associated Diphyllobothrium pacificum typically matures in seals or other marine mammals and attains only about half the length of Diphyllobothrium latum. Medication includes administration of the drug, niclosamide, which is accessible to physicians via Centers for Disease Control’s Parasitic Disease Drug Service. (more…)

The Giardia Lamblia

Giardia lamblia or intestinalis is a single-celled animal, a protozoan that mobilizes with the help of five flagella as seen by means of microscopy using a microscope like the brightfield light microscope. In Europe, it is sometimes called as Lamblia intestinalis. Giardiasis is the most often reason of non-bacterial diarrhea in North America. (more…)

The Cryptosporidium Parvum

Cryptosporidium parvum is a unicellular animal, a protozoan, as examined via microscopy using a microscope such as brightfield light microscope. It is an obligate intracellular parasitic organism. It has been provided additional species terminologies when isolated from various hosts. It is presently thought that the variety contaminating the humans is the identical species that causes illness in young calves. The varieties that contaminate avian hosts and those that contaminate mice are not thought capable of contaminating humans. Cryptosporidium specie contaminates many herd animals like cows, sheep, goats, deer and elk. The infective phase of the organism, which is the oocyst, is three micrometers in diameter or approximately half the size of a red blood cell as examined through microscopy under the microscope such as brightfield light microscope. The sporocysts are defiant to most chemical disinfectants but are vulnerable to drying and the ultraviolet portion of sunlight. Certain strains seem to be adapted to some hosts but cross-strain contagion transpires and may or may not be connected with the disease. The species or strain contaminating the respiratory system is not presently differentiated from the type contaminating the intestines. (more…)

The Enteroinvasive Escherichia Coli

Enteroinvasive Escherichia coli or EIEC is just one of the four identified classes of enterovirulent Escherichia coli that trigger gastroenteritis in humans as verified by examinations performed via microscopy using a microscope like the brightfield light microscope. Escherichia coli organism inhabits in humans and other primates, as part of their normal intestinal flora, as observed by means of microscopy using a microscope like the brightfield light microscope. A minority of Escherichia coli strains are able to initiate human disease by several various mechanisms. Among these are the enteroinvasive or EIEC strains. It is not known what foods may conceal these pathogenic enteroinvasive strains. Such enteroinvasive or EIEC strains are accountable for a type of bacillary dysentery. (more…)

The Entamoeba Histolytica

Entamoeba histolytica is a unicellular parasitic animal as observed by means of microscopy under the microscope like the brightfield light microscope. It is a protozoan, which contaminates mainly humans and other primates. Varied mammals like the dogs and cats can become contaminated but commonly do not shed cysts with their stools, as examined via microscopy using a microscope such as brightfield light microscope, hence do not contribute essentially to transmission. Cysts are the ecological survival form of the organism, which can be viewed through microscopy using a microscope like the brightfield light microscope. The active or the trophozoite stage emerges only in the host and in fresh stools as examined by means of microscopy using the brightfield light microscope. Cysts stay alive outside the host, in water and soils and on foods, particularly under damp conditions on the latter. When ingested they trigger contaminations by excysting to the trophozoite stage inside the digestive tract. (more…)

When Bacteria Hijacks The Immune System

Legionnaire’s disease is a severe type of infection caused by an aquatic organism that increases in warm environment known as Legionella pnuemophila. As such, this infection produces the disease called pneumonia. Legionnaire’s disease obtained its name during an outbreak of pneumonia in 1976, when the bacteria infected the participants of the American Legion convention in Philadelphia. (more…)

The Rise of Super Ear Bugs

The Journal of the American Medical Association has recently reported that a strain of bacteria has been discovered to be resistant to all approve drugs used as medication for ear infections in children. This was revealed to a couple of pediatricians, who perform an infrequent procedure called tympanocentesis or ear tap as their standard practice on their patients, when several antibiotic treatments failed to achieve the desired results. Tympanocentesis is conducted by puncturing the eardrum of the child in order to drain fluid so as to relieve pressure and pain. Then, the drained fluid is analyzed in order to identify the strain of bacteria responsible for causing the ear infection. (more…)

Bacterial Manipulation in Plants

brightfieldlightmicroscope — Thu, 06 Dec 2007 07:18:00 +0000

Bacteria are able to cause tumors in plants because they can modify the genomes of plants. Such alteration is done by skillfully using the first line of defense of plants. With the use of the proteins found in plants, the genes of such bacteria break into the plant nucleus. Then, such bacteria gain access to the plant genome. There, they reprogram the metabolism of plants to suit their needs. (more…)

Genome Sequencing Blanks for Antibiotic Discovery

brightfieldlightmicroscope — Thu, 06 Dec 2007 07:17:21 +0000

The U.S. Department of Energy Joint Genome Institute (DOE JGI) has recently conducted a systematic analysis from public databases on the substantial backlog of microbial genome sequences. Their recent study led to the identification of genes that kill bacteria, which are used in the sequencing process. As such, this may result to the formation of new strategies in approaching discoveries for new antibiotics. (more…)

Gut Bacteria for Drug Safety

brightfieldlightmicroscope — Thu, 06 Dec 2007 07:15:31 +0000

Researchers in Michigan, headed by Cynthia M. Rohde, have recently reported that bacteria thriving inside the intestines of laboratory rats may influence the outcome of drug safety and other tests. The research team has also noted that there has been an increasing recognition on the hidden roles that some 100 trillion bacteria that are living in human intestines. (more…)
