Mosquitos are common all over the world (approx. 2900 species). If at all, only the females suck blood. Aedes live very closely with people. When the skin is punctured, salivary secretions are released, which can transmit pathogens, e. g. filaria, dengue fever, yellow fever. If a female sucks up blood infected with yellow fever, for example, the pathogen multiplies in the cloak and new hosts can be infected within 4 days.
Clearly visible from top to bottom are the following: the outer layers of indigestible fruit shells that protect the grain from drying out, followed by aleuronk bodies (yellow-green massive grains), the biologically high quality seedshell and the aleuronk bodies (yellow-green massive grains). Wheat has been a cultivated plant and the main source of food for more than 20,000 years.
Portrait of a third stage larvae. The second of three larval stages of this fly species can be used to treat poorly healing, necrotizing wounds when other treatments fail. This applies in particular to for osteomyelitis, gangrene, ulcers caused by venostasis and mastoiditis. The sterile larvae are placed on the wounds and eliminate rotting, pus-stricken and already dead tissue. The healthy tissue is left completely in peace. The movement of the larvae and their metabolic products cleans the wound and stimulates wound healing. This method has been documented since the Middle Ages and is gaining importance with increasing antibiotic resistance.
Geraniaceae include the ornamental plant Pelargonium, which originated in South Africa, as well as species such as the cranesbill and the heron beak. They have glandular hairs (shown in yellow) which serve as excretion for the release of certain substances, be it to protect the plant from predators or to secrete harmful substances. In the picture you can also see too small thorns of shortened hair and split openings.
L. Destructor is a widespread stock mite. Mites belong to the arachnids and, unlike insects, have 4 pairs of legs. Plum mites grow up to 0.75 mm in size and feed on moulds, flour and rice. They thrive optimally at 25 ºC and high humidity. Also stock mites can be the cause of allergies.
The kidney is the body's filter organ. The picture shows the finest loops of a kidney corpuscle (Malpighi body) from the kidney cortex. In these vessels, the urinary substances (waste products of metabolism) are separated from the blood. The regulation of the body's water and electrolyte balance and the production of renal hormones (prostaglandin, renin, erythropoietin, vitamin D3, kinins) takes place in the kidneys.
Infectious laboratory germs were sent by terrorists to television stations in 2001 in the USA and by letter to congressmen.
The picture shows the mouth parts of an adult animal, seen from below. Ticks go through 3 stages of development up to the sexually mature animal and have a different host animal (e. g. mouse, rabbit, human or big game) in each phase, with which they suck blood. Dermacentor ticks are often carriers of rickettsia (bacteria) which, when transmitted to humans, cause spotted fever (rickettsiosis), which causes the death of about 70% of those affected.
Herpes viruses in the intercellular cavity. Red: genetic material, blue: capsid (shell), yellow: lipid layer. Disease pattern: Vesicular inflammation in the mouth and throat. For weak resistance, colds and strong sunlight. Treatment: specific ointments.
Fleas are blood-sucking insects. The species found in cats and dogs also occasionally affect humans, but after a few stings they abandon this false host. They can transmit pathogens, e. g.: Rickettsias (bacteria) or tapeworms. The breeding place of cat fleas is usually the sleeping place of the affected cat (dog).
Viruses are not capable of their own metabolism. They channel their DNA into foreign cells to use their metabolism and force their own reproduction. There are 16 different phages known for E. coli.
Lung (pulmo): organ of water respiration (oxygen uptake, carbon dioxide release) and regulation of water and heat balance. In the alveoli as the smallest unit, the gas exchange takes place. Erythrocytes absorb oxygen and emit carbon dioxide. (erythrocytes have escaped due to the preparation and are located in the lung vesicles).
Silverfish can be found in kitchens and bathrooms in humid places. They are wingless urinary insects with scaly skin, long, flexible probes and 3 bristles at the tail end. They feed on carbohydrates (sugar, flour...). Detailed view of the typical shed.
