Observation of marking-like behavior, marking behavior, and growth of the scent gland in young Mongolian gerbils (Meriones unguiculatus) of an inbred strain. (1/135)
A marking-like behavior (defined by authors), a marking behavior, and growth of the scent glands were observed in young Mongolian gerbils of an inbred strain. In males and females, a marking-like behavior, in which animals rub their abdominal scent glands on the floor, began to be seen at the age of 19 days and could be seen in almost all the gerbils at 22 days of age during the suckling period. The frequency of this behavior was highest at 60 days of age (males: 17.9/10 min, females: 15.4/10 min) and there was no sex difference. Marking behavior, in which animals rub their abdominal scent glands on small protruding objects, began to be seen at the age of 40 days in males and 50 days in females. The frequency of this behavior tended to increase until 90 days of age in males (13.7/10 min), but the levels were low (2.5-5.0/10 min) in females. The values in the male group therefore tended to be higher than that in the female group. Macroscopic scent gland pads were clearly observed at the age of 30 days in males, but not until 45 days of age in females. At the age of 45-90 days, the length of the scent gland pad in males and females was 2.1-2.8 and 1.6-1.7 cm, respectively and the width was 0.3-0.5 in males and 0.2-0.3 cm in females. During this period, the length and depth of the pads in males were significantly greater than those in females (p < 0.05). Histological examination of the structure of the scent glands after the age of 45 days showed that the development of clusters of acinar cells in females occurred much later than that in males, but the basic structure of these glands was similar in both sexes. These results suggest that the marking-like behavior was manifested although during the period when the scent glands had not yet developed, whereas true marking behavior first occurred when the glands were moderately well developed. (+info)Serum biochemical values in two inbred strains of mastomys (Praomys coucha). (2/135)
Serum samples collected from 119 (72 male and 47 female) mastomys (Praomys coucha) of 2 specific-pathogen-free inbred strains (RI4 and RI7) were analyzed for 12 serum biochemical parameters. Sex-related differences (p < 0.01) were noted in alkaline phosphatase and glucose; the both higher in females than in males. Age-related changes (p < 0.01) were observed in total protein, albumin, total cholesterol, and alkaline phosphatase, with higher values for the first three parameters in the older group (200-250 days of age) than in the younger group (90-140 days of age). Four out of 12 parameters showed strain-related differences (p < 0.01), consistent with the large amount of genetic heterogeneity reported in this species. These serum biochemical reference values should provide information for the use of mastomys in laboratory research. (+info)Characterization of early follicular cDNA library suggests evidence for genetic polymorphisms in the inbred strain C108 of Bombyx mori. (3/135)
Recent work towards the completion of a saturated molecular genetic linkage map for the lepidopteran silkworm, Bombyx mori (n = 28), has provided evidence for existing polymorphisms in the inbred strain C108. Two inbred parental strains, p50 and C108, were crossed to produce the F1 (P/C) hybrid offspring. The populations used in this project were comprised of a combination of 29 F2 (F1 x F1) and 31 reciprocal backcross (P/C x C/C, P/C x P/P) progeny. All restriction fragment length polymorphisms (RFLPs) for the initial analysis were hybridized with anonymous probes derived from a random early follicular cDNA (Rcf) library from Bombyx. A total of 19 Rcf probes were selected as showing scorable codominant polymorphic patterns when screened against F2 and backcross DNAs digested with the restriction enzymes EcoRI, HindIII, or PstI, and Southern blotted to nylon membranes for hybridization. Of the newly reported Rcf probes, 7 (37%) were characterized as producing 'simple' polymorphic patterns, while 12 (63%) were characterized as producing 'complex' polymorphic patterns. Further characterization of the complex patterns subdivided this group into two general classes: polymorphisms that contained an additional allele, and multiple bands that contained an easily scored two banded polymorphism. Because the extra allele class was limited to the (P/C x C/C) backcross progeny, it is suggested that the inbred parental strain C108 harbors polymorphic loci that are inherited in a simple Mendelian fashion. A genetic analysis discussing plausible origins and maintenance of these polymorphisms is presented. (+info)Trigonocephaly in rabbits with familial interfrontal suture synostosis: the multiple effects of premature single-suture fusion. (4/135)
Previous studies from our laboratory have characterized the craniofacial morphology and growth patterns of an inbred strain of rabbits with autosomal dominant coronal suture synostosis. A number of rabbit perinates from this colony have been collected sporadically over a 5-year period with premature interfrontal suture synostosis. The present study describes the very early onset of craniofacial dysmorphology of these rabbits and compares them to similar-aged normal control rabbits. A total of 40 perinatal New Zealand White rabbits were used in the present study. Twenty-one comprised the sample with interfrontal suture synostosis and ranged in age from 27 to 38 days postconception (term = 31 days) with a mean age of 33.53 days (+/-2.84 days). Nineteen rabbits served as age-matched, normal controls (mean age = 33.05 days +/-2.79 days). Lateral and dorsoventral radiographs were collected from each rabbit. The radiographs were traced, computer digitized, and 12 craniofacial measurements, angles, and indices were obtained. Mean measures were compared using an unpaired Student's t-test. All synostosed rabbits were stillborn or died shortly after birth. Grossly, these rabbits exhibited extreme frontal bossing, trigonocephaly with sagittal keeling, and midfacial shortening. No somatic anomalies were noted. Radiographically, rabbits with interfrontal suture synostosis had significantly (P < 0.05) narrower bifrontal widths, shorter cranial vault lengths, kyphotic cranial base angles, and different cranial vault indices (shapes) compared to controls. Results reveal severe and early pathological and compensatory cranial vault changes associated with premature interfrontal suture synostosis in this rabbit model. The 100% mortality rate noted in this condition may be related to the inheritance of a lethal genetic mutation or to neural compression from reduced intracranial volume. Results are discussed in light of current pathogenic hypotheses for human infants with premature metopic suture synostosis. (+info)Factors affecting the efficiency of embryo cryopreservation and rederivation of rat and mouse models. (5/135)
The efficiency of embryo banking for rat and mouse models of human disease and normal biological processes depends on the ease of obtaining embryos. Authors report on the effect of genotype on embryo production and rederivation. In an effort to establish banks of cryopreserved embryos, they provide two databases for comparing banking efficiency: one that contains the embryo collection results from approximately 11,000 rat embryo donors (111 models) and another that contains the embryo collection results from 4,023 mouse embryo donors (57 induced mutant models). The genotype of donor females affected the efficiency of embryo collection in two ways. First, the proportion of females yielding embryos varied markedly among genotypes (rats: 16-100 %, mean =71 %; mice: 24-95 %, mean =65 %). Second, the mean number of embryos recovered from females yielding embryos varied considerably (rats: 4-10.6, mean =7.8; mice 5.3-32.2, mean =13.7). Genotype also affected the efficiency of rederivation of banked rat and mouse embryos models by embryo transfer. For rats, thawed embryos (n =684) from 33 genotypes were transferred into 66 recipient females (pregnancy rate, 78 %). The average rate of developing live newborns for individual rat genotypes was 30 % with a range of 10 to 58 %. For mice, thawed embryos (n =2,064) from 59 genotypes were transferred into 119 pseudopregnant females (pregnancy rate: 76 %). The average rate of development of individual mouse genotypes was 33 % with a range of 11 to 53 %. This analysis demonstrates that genotype is an important consideration when planning embryo banking programs. (+info)NK and T cells constitute two major, functionally distinct intestinal epithelial lymphocyte subsets in the chicken. (6/135)
Non-mammalian NK cells have not been characterized in detail; however, their analysis is essential for the understanding of the NK cell receptor phylogeny. As a first step towards defining chicken NK cells, several tissues were screened for the presence of NK cells, phenotypically defined as CD8(+) cells lacking T- or B-lineage specific markers. By this criteria, approximately 30% of CD8(+) intestinal intraepithelial lymphocytes (IEL), but <1% of splenocytes or peripheral blood lymphocytes were defined as NK cells. These CD8(+)CD3(-) IEL were used for the generation of the 28-4 mAb, immunoprecipitating a 35-kDa glycoprotein with a 28-kDa protein core. The CD3 and 28-4 mAb were used to separate IEL into CD3(+) IEL T cells and 28-4(+) cells, both co-expressing the CD8 antigen. During ontogeny, 28-4(+) cells were abundant in the IEL and in the embryonic spleen, where two subsets could be distinguished according to their CD8 and c-kit expression. Most importantly, 28-4(+) IEL lysed NK-sensitive targets, whereas intestinal T cells did not have any spontaneous cytolytic activity. These results define two major, phenotypically and functionally distinct IEL subpopulations, and imply an important role of NK cells in the mucosal immune system. (+info)Construction of a BAC library derived from the inbred Hd-rR strain of the teleost fish, Oryzias latipes. (7/135)
A large insert genomic bacterial artificial chromosome (BAC) library was constructed from the inbred Hd-rR strain of the medaka, Oryzias latipes. Approximately 92,000 clones were gridded on high-density replica filters. Insert analysis of randomly selected clones indicated a mean insert size of 210 kb and predicted a 24 times coverage of the medaka genome. The library was hybridized with a single locus DNA fragment, and the resulting positive clones were characterized and shown to be compatible with a 24-fold redundant library. This first large insert genomic library of the medaka should increase the speed of genomic analyses for this fish species. (+info)Porcine endogenous retrovirus transmission characteristics of an inbred herd of miniature swine. (8/135)
Here we report the identification of inbred miniature swine that failed to produce human-tropic replication-competent porcine endogenous retroviruses (HTRC PERVs), using in vitro coculture assays. When HTRC PERVs were isolated from transmitting animals, all were recombinant viruses, with the receptor-binding domain of PERV-A combining with PERV-C-related sequences. (+info)There are several types of disease susceptibility, including:
1. Genetic predisposition: This refers to the inherent tendency of an individual to develop a particular disease due to their genetic makeup. For example, some families may have a higher risk of developing certain diseases such as cancer or heart disease due to inherited genetic mutations.
2. Environmental susceptibility: This refers to the increased risk of developing a disease due to exposure to environmental factors such as pollutants, toxins, or infectious agents. For example, someone who lives in an area with high levels of air pollution may be more susceptible to developing respiratory problems.
3. Lifestyle susceptibility: This refers to the increased risk of developing a disease due to unhealthy lifestyle choices such as smoking, lack of exercise, or poor diet. For example, someone who smokes and is overweight may be more susceptible to developing heart disease or lung cancer.
4. Immune system susceptibility: This refers to the increased risk of developing a disease due to an impaired immune system. For example, people with autoimmune disorders such as HIV/AIDS or rheumatoid arthritis may be more susceptible to opportunistic infections.
Understanding disease susceptibility can help healthcare providers identify individuals who are at risk of developing certain diseases and provide preventive measures or early intervention to reduce the risk of disease progression. Additionally, genetic testing can help identify individuals with a high risk of developing certain diseases, allowing for earlier diagnosis and treatment.
In summary, disease susceptibility refers to the predisposition of an individual to develop a particular disease or condition due to various factors such as genetics, environment, lifestyle choices, and immune system function. Understanding disease susceptibility can help healthcare providers identify individuals at risk and provide appropriate preventive measures or early intervention to reduce the risk of disease progression.
1) They share similarities with humans: Many animal species share similar biological and physiological characteristics with humans, making them useful for studying human diseases. For example, mice and rats are often used to study diseases such as diabetes, heart disease, and cancer because they have similar metabolic and cardiovascular systems to humans.
2) They can be genetically manipulated: Animal disease models can be genetically engineered to develop specific diseases or to model human genetic disorders. This allows researchers to study the progression of the disease and test potential treatments in a controlled environment.
3) They can be used to test drugs and therapies: Before new drugs or therapies are tested in humans, they are often first tested in animal models of disease. This allows researchers to assess the safety and efficacy of the treatment before moving on to human clinical trials.
4) They can provide insights into disease mechanisms: Studying disease models in animals can provide valuable insights into the underlying mechanisms of a particular disease. This information can then be used to develop new treatments or improve existing ones.
5) Reduces the need for human testing: Using animal disease models reduces the need for human testing, which can be time-consuming, expensive, and ethically challenging. However, it is important to note that animal models are not perfect substitutes for human subjects, and results obtained from animal studies may not always translate to humans.
6) They can be used to study infectious diseases: Animal disease models can be used to study infectious diseases such as HIV, TB, and malaria. These models allow researchers to understand how the disease is transmitted, how it progresses, and how it responds to treatment.
7) They can be used to study complex diseases: Animal disease models can be used to study complex diseases such as cancer, diabetes, and heart disease. These models allow researchers to understand the underlying mechanisms of the disease and test potential treatments.
8) They are cost-effective: Animal disease models are often less expensive than human clinical trials, making them a cost-effective way to conduct research.
9) They can be used to study drug delivery: Animal disease models can be used to study drug delivery and pharmacokinetics, which is important for developing new drugs and drug delivery systems.
10) They can be used to study aging: Animal disease models can be used to study the aging process and age-related diseases such as Alzheimer's and Parkinson's. This allows researchers to understand how aging contributes to disease and develop potential treatments.
1. Hantavirus pulmonary syndrome (HPS): This is a severe respiratory disease caused by the hantavirus, which is found in the urine and saliva of infected rodents. Symptoms of HPS can include fever, headache, muscle pain, and difficulty breathing.
2. Leptospirosis: This is a bacterial infection caused by the bacterium Leptospira, which is found in the urine of infected rodents. Symptoms can include fever, headache, muscle pain, and jaundice (yellowing of the skin and eyes).
3. Rat-bite fever: This is a bacterial infection caused by the bacterium Streptobacillus moniliformis, which is found in the saliva of infected rodents. Symptoms can include fever, headache, muscle pain, and swollen lymph nodes.
4. Lymphocytic choriomeningitis (LCM): This is a viral infection caused by the lymphocytic choriomeningitis virus (LCMV), which is found in the urine and saliva of infected rodents. Symptoms can include fever, headache, muscle pain, and meningitis (inflammation of the membranes surrounding the brain and spinal cord).
5. Tularemia: This is a bacterial infection caused by the bacterium Francisella tularensis, which is found in the urine and saliva of infected rodents. Symptoms can include fever, headache, muscle pain, and swollen lymph nodes.
These are just a few examples of the many diseases that can be transmitted to humans through contact with rodents. It is important to take precautions when handling or removing rodents, as they can pose a serious health risk. If you suspect that you have been exposed to a rodent-borne disease, it is important to seek medical attention as soon as possible.
Explanation: Genetic predisposition to disease is influenced by multiple factors, including the presence of inherited genetic mutations or variations, environmental factors, and lifestyle choices. The likelihood of developing a particular disease can be increased by inherited genetic mutations that affect the functioning of specific genes or biological pathways. For example, inherited mutations in the BRCA1 and BRCA2 genes increase the risk of developing breast and ovarian cancer.
The expression of genetic predisposition to disease can vary widely, and not all individuals with a genetic predisposition will develop the disease. Additionally, many factors can influence the likelihood of developing a particular disease, such as environmental exposures, lifestyle choices, and other health conditions.
Inheritance patterns: Genetic predisposition to disease can be inherited in an autosomal dominant, autosomal recessive, or multifactorial pattern, depending on the specific disease and the genetic mutations involved. Autosomal dominant inheritance means that a single copy of the mutated gene is enough to cause the disease, while autosomal recessive inheritance requires two copies of the mutated gene. Multifactorial inheritance involves multiple genes and environmental factors contributing to the development of the disease.
Examples of diseases with a known genetic predisposition:
1. Huntington's disease: An autosomal dominant disorder caused by an expansion of a CAG repeat in the Huntingtin gene, leading to progressive neurodegeneration and cognitive decline.
2. Cystic fibrosis: An autosomal recessive disorder caused by mutations in the CFTR gene, leading to respiratory and digestive problems.
3. BRCA1/2-related breast and ovarian cancer: An inherited increased risk of developing breast and ovarian cancer due to mutations in the BRCA1 or BRCA2 genes.
4. Sickle cell anemia: An autosomal recessive disorder caused by a point mutation in the HBB gene, leading to defective hemoglobin production and red blood cell sickling.
5. Type 1 diabetes: An autoimmune disease caused by a combination of genetic and environmental factors, including multiple genes in the HLA complex.
Understanding the genetic basis of disease can help with early detection, prevention, and treatment. For example, genetic testing can identify individuals who are at risk for certain diseases, allowing for earlier intervention and preventive measures. Additionally, understanding the genetic basis of a disease can inform the development of targeted therapies and personalized medicine."
Body weight is an important health indicator, as it can affect an individual's risk for certain medical conditions, such as obesity, diabetes, and cardiovascular disease. Maintaining a healthy body weight is essential for overall health and well-being, and there are many ways to do so, including a balanced diet, regular exercise, and other lifestyle changes.
There are several ways to measure body weight, including:
1. Scale: This is the most common method of measuring body weight, and it involves standing on a scale that displays the individual's weight in kg or lb.
2. Body fat calipers: These are used to measure body fat percentage by pinching the skin at specific points on the body.
3. Skinfold measurements: This method involves measuring the thickness of the skin folds at specific points on the body to estimate body fat percentage.
4. Bioelectrical impedance analysis (BIA): This is a non-invasive method that uses electrical impulses to measure body fat percentage.
5. Dual-energy X-ray absorptiometry (DXA): This is a more accurate method of measuring body composition, including bone density and body fat percentage.
It's important to note that body weight can fluctuate throughout the day due to factors such as water retention, so it's best to measure body weight at the same time each day for the most accurate results. Additionally, it's important to use a reliable scale or measuring tool to ensure accurate measurements.
The tumor usually grows slowly and may not cause any symptoms in its early stages. However, as it progresses, it can cause abdominal pain, bloating, and irregular vaginal bleeding. GCTs are generally diagnosed through a combination of pelvic examination, imaging studies such as ultrasound or computed tomography (CT), and biopsy.
There are several subtypes of GCT, including:
1. Granulosa cell tumor with stromal element (GCT-SE): This is the most common type of GCT and accounts for about 70% of all cases. It is characterized by the presence of stromal cells, which are connective tissue cells that provide support and structure to the tumor.
2. Granulosa cell tumor without stromal element (GCT-wSE): This type of GCT lacks stromal cells and accounts for about 30% of all cases. It tends to be more aggressive than GCT-SE and is more likely to spread to other parts of the body.
3. Mucinous granulosa cell tumor (MGCT): This is a rare subtype of GCT that produces mucin, a type of protein that is found in the ovary. MGCTs tend to be slower-growing than other types of GCT and have a better prognosis.
Treatment for GCT typically involves surgery to remove the tumor, followed by radiation therapy and/or chemotherapy to destroy any remaining cancer cells. The prognosis for GCT is generally good, with a 5-year survival rate of about 80% for women with early-stage disease. However, the prognosis can be poorer for women with more advanced stages of the disease.
In summary, granulosa cell tumor is a rare type of ovarian cancer that originates from the granulosa cells of the ovary. It can present in different forms and has a good prognosis if treated early. Treatment typically involves surgery, radiation therapy, and/or chemotherapy.
A sprain is a stretch or tear of a ligament, which is a fibrous connective tissue that connects bones to other bones and provides stability to joints. Sprains often occur when the joint is subjected to excessive stress or movement, such as during a fall or sudden twisting motion. The most common sprains are those that affect the wrist, knee, and ankle joints.
A strain, on the other hand, is a stretch or tear of a muscle or a tendon, which is a fibrous cord that connects muscles to bones. Strains can occur due to overuse, sudden movement, or injury. The most common strains are those that affect the hamstring, calf, and back muscles.
The main difference between sprains and strains is the location of the injury. Sprains affect the ligaments, while strains affect the muscles or tendons. Additionally, sprains often cause joint instability and swelling, while strains may cause pain, bruising, and limited mobility.
Treatment for sprains and strains is similar and may include rest, ice, compression, and elevation (RICE) to reduce inflammation and relieve pain. Physical therapy exercises may also be recommended to improve strength and range of motion. In severe cases, surgery may be required to repair the damaged tissue.
Prevention is key in avoiding sprains and strains. This can be achieved by maintaining proper posture, warming up before physical activity, wearing appropriate protective gear during sports, and gradually increasing exercise intensity and duration. Proper training and technique can also help reduce the risk of injury.
Overall, while sprains and strains share some similarities, they are distinct injuries that require different approaches to treatment and prevention. Understanding the differences between these two conditions is essential for proper diagnosis, treatment, and recovery.
Here are some common types of E. coli infections:
1. Urinary tract infections (UTIs): E. coli is a leading cause of UTIs, which occur when bacteria enter the urinary tract and cause inflammation. Symptoms include frequent urination, burning during urination, and cloudy or strong-smelling urine.
2. Diarrheal infections: E. coli can cause diarrhea, abdominal cramps, and fever if consumed through contaminated food or water. In severe cases, this type of infection can lead to dehydration and even death, particularly in young children and the elderly.
3. Septicemia (bloodstream infections): If E. coli bacteria enter the bloodstream, they can cause septicemia, a life-threatening condition that requires immediate medical attention. Symptoms include fever, chills, rapid heart rate, and low blood pressure.
4. Meningitis: In rare cases, E. coli infections can spread to the meninges, the protective membranes covering the brain and spinal cord, causing meningitis. This is a serious condition that requires prompt treatment with antibiotics and supportive care.
5. Hemolytic-uremic syndrome (HUS): E. coli infections can sometimes cause HUS, a condition where the bacteria destroy red blood cells, leading to anemia, kidney failure, and other complications. HUS is most common in young children and can be fatal if not treated promptly.
Preventing E. coli infections primarily involves practicing good hygiene, such as washing hands regularly, especially after using the bathroom or before handling food. It's also essential to cook meat thoroughly, especially ground beef, to avoid cross-contamination with other foods. Avoiding unpasteurized dairy products and drinking contaminated water can also help prevent E. coli infections.
If you suspect an E. coli infection, seek medical attention immediately. Your healthcare provider may perform a urine test or a stool culture to confirm the diagnosis and determine the appropriate treatment. In mild cases, symptoms may resolve on their own within a few days, but antibiotics may be necessary for more severe infections. It's essential to stay hydrated and follow your healthcare provider's recommendations to ensure a full recovery.
Examples of experimental leukemias include:
1. X-linked agammaglobulinemia (XLA): A rare inherited disorder that leads to a lack of antibody production and an increased risk of infections.
2. Diamond-Blackfan anemia (DBA): A rare inherited disorder characterized by a failure of red blood cells to mature in the bone marrow.
3. Fanconi anemia: A rare inherited disorder that leads to a defect in DNA repair and an increased risk of cancer, particularly leukemia.
4. Ataxia-telangiectasia (AT): A rare inherited disorder characterized by progressive loss of coordination, balance, and speech, as well as an increased risk of cancer, particularly lymphoma.
5. Down syndrome: A genetic disorder caused by an extra copy of chromosome 21, which increases the risk of developing leukemia, particularly acute myeloid leukemia (AML).
These experimental leukemias are often used in research studies to better understand the biology of leukemia and to develop new treatments.
There are several types of ataxia, each with different symptoms and causes. Some common forms of ataxia include:
1. Spinocerebellar ataxia (SCA): This is the most common form of ataxia and is caused by a degeneration of the cerebellum and spinal cord. It can cause progressive weakness, loss of coordination, and difficulty with speaking and swallowing.
2. Friedreich's ataxia: This is the second most common form of ataxia and is caused by a deficiency of vitamin E in the body. It can cause weakness in the legs, difficulty walking, and problems with speech and language.
3. Ataxia-telangiectasia (AT): This is a rare form of ataxia that is caused by a gene mutation. It can cause progressive weakness, loss of coordination, and an increased risk of developing cancer.
4. Acute cerebellar ataxia: This is a sudden and temporary form of ataxia that can be caused by a variety of factors such as infections, injuries, or certain medications.
5. Drug-induced ataxia: Certain medications can cause ataxia as a side effect.
6. Vitamin deficiency ataxia: Deficiencies in vitamins such as vitamin B12 or folate can cause ataxia.
7. Metabolic disorders: Certain metabolic disorders such as hypothyroidism, hyperthyroidism, and hypoglycemia can cause ataxia.
8. Stroke or brain injury: Ataxia can be a result of a stroke or brain injury.
9. Multiple system atrophy (MSA): This is a rare progressive neurodegenerative disorder that can cause ataxia, parkinsonism, and autonomic dysfunction.
10. Spinocerebellar ataxia (SCA): This is a group of rare genetic disorders that can cause progressive cerebellar ataxia, muscle wasting, and other signs and symptoms.
It's important to note that this is not an exhaustive list and there may be other causes of ataxia not mentioned here. If you suspect you or someone you know may have ataxia, it is important to consult a healthcare professional for proper diagnosis and treatment.
Staphylococcal infections can be classified into two categories:
1. Methicillin-Resistant Staphylococcus Aureus (MRSA) - This type of infection is resistant to many antibiotics and can cause severe skin infections, pneumonia, bloodstream infections and surgical site infections.
2. Methicillin-Sensitive Staphylococcus Aureus (MSSA) - This type of infection is not resistant to antibiotics and can cause milder skin infections, respiratory tract infections, sinusitis and food poisoning.
Staphylococcal infections are caused by the Staphylococcus bacteria which can enter the body through various means such as:
1. Skin cuts or open wounds
2. Respiratory tract infections
3. Contaminated food and water
4. Healthcare-associated infections
5. Surgical site infections
Symptoms of Staphylococcal infections may vary depending on the type of infection and severity, but they can include:
1. Skin redness and swelling
2. Increased pain or tenderness
3. Warmth or redness in the affected area
4. Pus or discharge
5. Fever and chills
6. Swollen lymph nodes
7. Shortness of breath
Diagnosis of Staphylococcal infections is based on physical examination, medical history, laboratory tests such as blood cultures, and imaging studies such as X-rays or CT scans.
Treatment of Staphylococcal infections depends on the type of infection and severity, but may include:
1. Antibiotics to fight the infection
2. Drainage of abscesses or pus collection
3. Wound care and debridement
4. Supportive care such as intravenous fluids, oxygen therapy, and pain management
5. Surgical intervention in severe cases.
Preventive measures for Staphylococcal infections include:
1. Good hand hygiene practices
2. Proper cleaning and disinfection of surfaces and equipment
3. Avoiding close contact with people who have Staphylococcal infections
4. Covering wounds and open sores
5. Proper sterilization and disinfection of medical equipment.
It is important to note that MRSA (methicillin-resistant Staphylococcus aureus) is a type of Staphylococcal infection that is resistant to many antibiotics, and can be difficult to treat. Therefore, early diagnosis and aggressive treatment are crucial to prevent complications and improve outcomes.
There are several types of diarrhea, including:
1. Acute diarrhea: This type of diarrhea is short-term and usually resolves on its own within a few days. It can be caused by a viral or bacterial infection, food poisoning, or medication side effects.
2. Chronic diarrhea: This type of diarrhea persists for more than 4 weeks and can be caused by a variety of conditions, such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), or celiac disease.
3. Diarrhea-predominant IBS: This type of diarrhea is characterized by frequent, loose stools and abdominal pain or discomfort. It can be caused by a variety of factors, including stress, hormonal changes, and certain foods.
4. Infectious diarrhea: This type of diarrhea is caused by a bacterial, viral, or parasitic infection and can be spread through contaminated food and water, close contact with an infected person, or by consuming contaminated food.
Symptoms of diarrhea may include:
* Frequent, loose, and watery stools
* Abdominal cramps and pain
* Bloating and gas
* Nausea and vomiting

Roman1
- We have evaluated whether a genetically-selected rat model, the Roman high-avoidance inbred strain (RHA-I), displays PPI deficits as compared with its Roman low-avoidance (RLA-I) counterpart and the genetically heterogeneous NIH-HS rat stock. (unica.it)
Sensitivity1
- Many types of research are also performed by utilizing strain differences in responses such as sensitivity and resistance. (nih.gov)
Genetic11
- Laboratory animals may be divided into three major genetic types: inbred animals, hybrid animals, and closed colonies. (nih.gov)
- Almost no genetic differences can be found between any two animals within a particular inbred strain. (nih.gov)
- However, because there are major genetic differences from one inbred strain to another (for example, in responses to drugs) there may be completely different results (such as a high response level in one strain and a low level in another). (nih.gov)
- Examples of this research include biochemical studies on substances that cause strain differences such as proteins and enzymes and genetic studies on strain differences. (nih.gov)
- Gene polymorphism is maintained in closed colonies, and the genotypes of individual animals are known to differ based on genetic testing ( Katoh and others 1998 ). (nih.gov)
- Standard inbred laboratory mice are resistant to MPXV infection, and the absence of a small animal model of mpox has made it difficult to study how genetic differences contribute to observed differences in virulence. (nih.gov)
- The authors conclude that the major differences observed for permanent threshold shift in the B6 and B6D2F1-mice and the minimal temporary threshold shifts in the CB and CBB6F1-mice support the hypothesis for a major genetic difference among these strains. (cdc.gov)
- The genetic background of the host animal exerts great influence on the tumor frequency and/or the resultant latency of a particular transgene or mutation, as well as the systemic host immune responses. (nih.gov)
- To maximize the use of animal models, genetic technologies for more species need to be developed, technologies for mice need to be enhanced to allow simultaneous mutation of multiple genes so that complex diseases are more effectively modeled, outbred strains need to be increasingly utilized, and zebrafish mutants should be more systematically phenotyped. (nih.gov)
- These animal models resemble human skin cancer development, in that genetic changes caused by carcinogens and pro‑inflammatory cytokines, and simultaneous inflammation sustained by pro‑inflammatory cytokines and chemokines favor tumor progression. (spandidos-publications.com)
- Less well understood, though, is whether individuals are recognised through variation in cues that arise incidentally from a wide variety of genetic and non-genetic differences between individuals, or whether animals evolve distinctive polymorphic signals to advertise identity reliably.

(nih.gov)
- After careful examination of signals from our mapping of baboons, and separately of the inbred mouse cross, we have come to the startling finding, with high levels of statistical significance rarely matched by other GWAS on this subject, that neither Bmp nor FGF genes are involved in head-shape development!

- It is probably not possible for humans to acquire a Sterne strain infection by the respiratory or oral route. (cdc.gov)
- While it is highly unlikely that the Sterne strain will result in infection, cutaneous anthrax can be successfully treated with antimicrobial agents, making it improbable that a localized infection can become severe or fatal. (cdc.gov)
Identify2
- In each case, marker loci across the genome were typed on all animals and the GWAS-like approach was taken to identify markers in genome areas in which variation was associated with various head dimensions (as shown in the figure). (blogspot.com)

MPXV2
- The development of small animal models for the study of monkeypox virus (MPXV) has been quite extensive for the relatively short period of time this pathogen has been known, although only a few of these models have been used to study anti-poxvirus agents. (nih.gov)
- We will review those MPXV small animal models that have been developed thus far for the study of therapeutic agents. (nih.gov)
Microbiology1
- Routine manipulation of the strain in a microbiology laboratory is not likely to result in exposure. (cdc.gov)
Colony2
Data2
- Individual animal data were not submitted. (jax.org)
- In our work, we are using head shape data on a huge set of baboons who are deceased members of a huge and completely known genealogy housed in Texas, and a large study of over 1000 mice from a well-controlled cross between two inbred parental strains. (blogspot.com)
Responses1
- The SJL/J strain appeared to exhibit one of the greatest hypersensitivity responses with a 37.7% increase over the baseline ear thickness in the Be/Be group compared with a 2.6% increase in the control group. (cdc.gov)
Virulence4
- The resulting organism is attenuated, meaning its virulence and the ability to cause illness in people or animals have been reduced. (cdc.gov)
- In mice, the attenuated strains possess a low degree of virulence, due to toxin production. (cdc.gov)
- Second, the Sterne strain might regain pXO2 and revert to capsule production, resulting in wild-type virulence. (cdc.gov)
- No reversion to virulence has been seen in the Sterne strain since its discovery in 1937. (cdc.gov)
Disease3
- Monkeypox disease transmission in an experimental setting: prairie dog animal model. (nih.gov)
- Overall, in this model, LASV antigen was restricted to the anterior uvea and was associated with mild chronic inflammation in animals with severe disease but was not detected in survivors. (cdc.gov)
- No human disease due to anthrax caused by the Sterne strain has been reported. (cdc.gov)
Species2
- The cause of mammary tumors is unknown in any species except mice, in which an oncornavirus is causative in certain inbred strains. (msdvetmanual.com)
- No species, much less a single inbred strain, should be expected to be "broadly applicable" to model all diseases, and nature offers a wide range of phenotypes of interest, which may be more comparable to what is observed in human diseases. (nih.gov)
Study2
- In the aspiration study, seven inbred strains aspirated either 20µg, 35µg, or 50µg of beryllium metal powder or water vehicle monthly. (cdc.gov)
- Third, our work promotes the study of cellular division in prokaryotes and in protist mitosis to illuminate the evolutionary origin of the soma and germen division, traditionally studied in animals. (transhumanist.ru)
Stimulate2
- Compared with normal wild type strains which produce both the toxin and the capsule, the Sterne strain is relatively avirulent, however immunization using the Sterne strain is able to stimulate a protective immune response. (cdc.gov)
- By convening a meeting of experts in major chronic diseases (CVD, cancer, inflammation, neurodegeneration) and evolutionary biologists / animal researchers, the program could stimulate fruitful discussion of those models that are most worthy of further development and of the opportunities for enhancing mutagenesis methods in mice.
