Infections Caused by Bartonella
The Bartonella infections, also known as bartonellosis, are a group of complex diseases caused by bacteria belonging to the Bartonella genus. These infections are typically zoonotic, meaning they are transmitted from animals to humans. While the most well-known form is cat scratch fever, Bartonella bacteria can cause a variety of clinical symptoms, including neurological, cardiovascular, and dermatological manifestations. Due to the wide spectrum of effects of these infections, it is important to understand the biological characteristics of Bartonella bacteria, the modes of transmission, potential complications, and the challenges of diagnosis and treatment. The Biological Characteristics of Bartonella Bacteria The Bartonella genus includes Gram-negative bacteria, with more than 40 different species.…

Overweight Pregnant Women Are at Increased Risk of Infections.
The pregnancy is a special time in a woman’s life that comes with numerous physical and emotional changes. Expectant mothers often face various challenges that affect their health and the development of the fetus. One significant issue that arises during pregnancy is the relationship between weight and the immune system. Research shows that overweight expectant mothers have a weaker immune response, which can have serious consequences for both the mother and the child. More and more women are experiencing overweight conditions before conception, and this trend is concerning, as excess weight during pregnancy can pose risks not only to the mother but also to the unborn child. Due to a…

Flesh-eating bacteria: Streptococcus pyogenes
The Streptococcus pyogenes, commonly known as “flesh-eating bacteria,” is part of the normal human flora, found on the skin, in the nasopharyngeal region, and in the anogenital area of many people. Most individuals remain asymptomatic; however, under certain circumstances, it can cause severe and invasive infections. This bacterium can occur at any age, but research over the past decades indicates that young adults, particularly those aged 20-35, are at the highest risk. Streptococcus pyogenes is highly prevalent and causes a range of diseases, from relatively mild throat infections to severe, life-threatening conditions. The bacteria spread from person to person, primarily through respiratory droplets, but also through other means such as…

Frequent Infections May Indicate Immune System Disorders
The immune system plays a key role in maintaining our health by protecting the body from various pathogens, such as bacteria and viruses. However, there are certain cases where the immune system may not function properly, leading to immunodeficiency. This issue can be congenital, meaning it is present at birth, or secondary, when it develops due to some external factor. Immunodeficiency diseases can manifest in many forms, and the symptoms can be quite diverse. Particular attention is needed for children, as early signs often appear during infancy. However, there are also cases where problems remain hidden for decades. Disorders of the immune system can have serious consequences, so it is…

Infections in Hematological Diseases
The hematological diseases, such as various blood disorders, significantly impact the body’s immune response. These conditions weaken the immune system through various mechanisms, leading to an increased risk of infections for patients. As a result of the deterioration of immune function, hematological patients are much more susceptible to infections caused by various pathogens than healthy individuals. Causes of Increased Infection Susceptibility in Hematological Patients The aim of this article is to present the underlying causes of increased infection susceptibility in hematological patients, as well as the types of infections that most commonly occur in their cases. Hematological conditions such as leukemia or lymphoma affect the functioning of the bone marrow…

Infections Caused by Shigella (Shigellosis)
The Shigella bacteria are among the most common pathogens causing intestinal infections worldwide. Their spread primarily occurs through contact with food and water contaminated with feces, as well as touching infected surfaces. Such infections often occur in crowded and hygienically problematic environments, where the risk of outbreaks increases. Shigella bacteria are particularly dangerous because a very low number of bacteria may be sufficient to cause an infection. The bacteria can withstand stomach acid, allowing them to easily adhere once they enter the digestive system. During an infection, the bacteria penetrate the epithelial layer of the colon, causing severe inflammation and tissue destruction. There are several different strains of the Shigella…
