Generality Varicella incubation time is defined as the period between the contraction of the infection and the onset of symptoms. Chickenpox is a highly contagious infectious viral disease that causes a characteristic rash ( exanthema ). The infection that leads to the disease in question develops inside the patient slowly and initially asymptomatically

Leptospirosis As analyzed in the previous article, leptospirosis represents a group of infectious syndromes caused by spirochetes of the genus Leptospira. However, it should be pointed out that not all species of these microorganisms are pathogenic to humans: over 200 different serotypes are currently recognized - known with the name serovar - and the serovar icterohaemorrhagiae is certainly the most dangerous and virulent

Definition of leptospirosis "Leptospirosis" is a general term comprising a series of systemic infectious zoonoses, with an acute course, caused by bacteria belonging to the genus Leptospira . Leptospirosis is known by many synonyms, and among the best known are: autumn fever (akiyami, in the Japanese language), seven-day fever (nanukayami, in Japanese), swine fever or - in the case of icteric leptospirosis - swamp fever, mud fever, dog-cutter fever or jaundice hemorrhage

Key points Lymphangitis (or blood poisoning) is an inflammation of the lymphatic vessels with a predominantly bacterial etiology. Lymphangitis: causes Most of the diagnosed lymphangitis is triggered by streptococci. Also other pathogens can trigger lymphangitis: staphylococci, Spirillum minus , Brugia malayi , Pasteurella multocida and Wuchereria bancrofti

Generality Yeasts , from those with pathogenic to harmless properties, are eukaryotic microorganisms consisting of a single cell and belonging to the kingdom of fungi. Heterotrophic living beings, yeasts reproduce by binary splitting or budding, they prefer damp environments and do not grow by means of so-called hyphae (which instead are typical of all other species of mushrooms)

Key points Sleeping sickness (or African trypanosomiasis) is a parasitic infection transmitted to humans by the bite of an infected tsetse fly. Causes Sleeping sickness is caused by a flagellated protozoan parasite, Trypanosoma brucei : Trypanosoma brucei rhodesiense : etiological agent of East African trypanosomiasis (subacute sleep disease, which presents a violent and brief course) Tripanosoma brucei gambiens : causal agent of the Gambian African sleeping sickness (chronic trypanosomiasis) Symptoms Hemolymphatic phase of sleeping sickness: joint pain, intermittent fever, swollen lymph nodes

What is Lyme disease? Lyme disease is a pathology of bacterial origin that mainly affects the skin, but often internal organs, joints and the nervous system are also affected. Lyme disease belongs to the anthropozoonosis group, that is to say that group of diseases that can be transmitted naturally from vertebrate animals to humans

Introduction Although they usually populate the respiratory mucosa without causing damage, pneumococci, finding the optimal conditions for them, can replicate themselves disproportionately, transforming themselves from commensal microorganisms to terrible opportunistic pathogens, capable of triggering diseases of varying size
