Phenotypic Changes in Mammary Adenocarcinoma (4T1) cells In Vitro after Treatment with Carcinosinum.

Objective: The present study aimed to identify possible phenotypic changes in 4T1 (murine mammary adenocarcinoma) cells , including viability, HER-2 (human epidermal growth factor receptor-type 2) expression, and metastatic potential, after treatment with in different homeopathic dilutions (12cH, 30cH, 200cH) shaken mechanically in pure, sterile, water from a commercial stock dilution.

Methods: Treated cells were cultured in R10 medium, using 24-well plates, 10 cells per well, and treated with vehicle, 12cH, 30cH or 200cH; untreated cells were used as the baseline control. After 24 hours of treatment, the percentage of apoptotic cells was analyzed by annexin V.

Opportunistic pneumonia caused by E. cuniculi in mice immunosuppressed with cyclophosphamide.

Opportunistic fungal pneumonia is a cause of concern in immunocompromised patients due to its high morbidity and mortality rates. One such opportunistic agent affecting immunocompromised patients is the microsporidia called Encephalitozoon cuniculi. This study aimed to evaluate pneumonia caused by E.

Unexpected rabies variant identified in kinkajou (), Mato Grosso, Brazil.

A second case of a novel rabies variant described once in a capuchin monkey from Mato Grosso, Brazil, was discovered in a rabid wild kinkajou from the same region, indicating a public health risk following exposure to either of the two animals.

Hyperprolactinemia Impaired the Effects of Lipopolysaccharide on Both Body Temperature and Sickness Behavior in Virgin Female Rats.

Objective: Previously we observed an attenuation of body temperature in lactating rats treated with lipopolysaccharide (LPS) compared with virgin saline-treated females. We proposed that high levels of prolactin (PRL) during lactation may induce this attenuation because PRL has a suppressive effect on inflammation. In the present study, we induced hyperprolactinemia in female virgin rats to investigate the effects of PRL on body temperature and sickness behavior induced by LPS.

Cyclophosphamide Treatment Mimics Sub-Lethal Infections With in Immunocompromised Individuals.

Microsporidia, including , are emerging pathogens which cause opportunistic infections in immunocompromised patients, such as those with AIDS, cancer, the elderly and people on immunosuppressive drugs. Intestinal mucosa (IM) is crucial for developing an efficient adaptive immune response against pathogenic micro-organisms, thereby preventing their colonization and subsequent infection. As immunosuppressive drugs affect the intestinal immune response is little known.

Chemobrain in rats: Behavioral, morphological, oxidative and inflammatory effects of doxorubicin administration.

Doxorubicin (DOX) is known to cause cognitive impairments in patients submitted to long-term chemotherapy (deficits also known as chemobrain). The present study investigated whether DOX administration could affect behavior and brain morphology, as well as oxidative and inflammatory status in rats. Male Wistar rats were injected with DOX (2.

B-1 cells upregulate CD8 T lymphocytes and increase proinflammatory cytokines serum levels in oral encephalitozoonosis.

Microsporidia are intracellular pathogens that cause severe disease in immunocompromised humans and animals. We recently demonstrated that XID mice are more susceptible to Encephalitozoon cuniculi infection by intraperitoneal route, evidencing the role of B-1 cells in resistance against infection. The present study investigated the resistance and susceptibility against E.

Diabetes mellitus increases the susceptibility to encephalitozoonosis in mice.

Microsporidiosis are diseases caused by opportunistic intracellular fungi in immunosuppressed individuals, as well as in transplanted patients, the elderly and children, among others. Diabetes mellitus (DM) is a metabolic disease characterized by hyperglycemia and decreased T cell response, neutrophil function, humoral immunity failure, increasing the susceptibility to infections. Here, we investigated the susceptibility of streptozotocin (STZ)-induced type I diabetic and/or immunosuppressed mice to encephalitozoonosis by Encephalitozoon cuniculi.

How Behavioral Changes Can Indicate Serious Cerebral Pathology: A Case Report of Concomitant Olfactory Neuroblastoma and Distemper Virus Encephalitis in a Swiss Shepherd Dog.

Behavioral alterations in dogs are not easy to understand and cure. The situation is more difficult when an encephalitis due to (CDV) and a concomitant olfactory neuroblastoma are present. This case report deals with the story of a 5-year-old Swiss shepherd dog with behavioral changes, seizures, epistaxis and ataxia.

B-1 cell decreases susceptibility to encephalitozoonosis in mice.

Encephalitozoon cuniculi is an opportunist intracellular pathogen of mammals. The adaptive immune response is essential to eliminate E. cuniculi, but evidence is mounting that the response initiated by the innate immune response may ultimately define whether or not the parasite can survive.

Culture and propagation of microsporidia of veterinary interest.

Microsporidia are obligate intracellular mitochondria-lacking pathogens that rely on host cells to grow and multiply. Microsporidia, currently classified as fungi, are ubiquitous in nature and are found worldwide. They infect a large number of mammals and are recognized as opportunistic infection agents in HIV-AIDS patients.

Ruminant rhombencephalitis-associated Listeria monocytogenes strains constitute a genetically homogeneous group related to human outbreak strains.

Listeriosis is a disease that causes significant economic losses at the farm level because of high morbidity and mortality in ruminants. This study was performed to investigate the role of ruminants in the epidemiology of listeriosis in northern Italy and the possible association of animal-adapted strains of Listeria monocytogenes with strains associated with human disease. Twenty ruminant rhombencephalitis isolates previously confirmed as L.

Atypical cerebral listeriosis associated with Listeria innocua in a beef bull.

Natural infections of cattle associated with Listeria innocua have not been reported. This report describes the first case of cerebral listeriosis in a bull due to Listeria innocua. The animal presented neurological signs characterized by weakness, incoordination and recumbency.
