Strongyloides Stercoralis

When the Larvae are ingested by a human they turn into adult tapeworms and live in the intestines of humans, this is called an intestinal infection. They can live for up to 30- years in there host

Dirofilaria immitis (D. immitis) is a nematode parasite, which causes heartworm or cardiopulmonary disease, in dogs, and is transmitted by culicide mosquitoes. This type of parasitism could be fatal for dog’s population so, they can die if this illness is not treated appropiately. In addition, the presence of D. immitis in canine poulations implies certain risk to produce zoonotic infections, so that, humans could be infected too (human pulmonary dirofilariosis). Cardiopulmonary dirofilariosis has got a cosmopolite distribution, and it is an endemic disease in lots of countries all over the world. Furthermore, it has been spread from these endemic regions durig the last years, so it has appeared in some places where there was not cases reported

5. What species is the intended host for the Baylisascaris nematode and what symptoms does it cause in this host?

The organism adheres to the epithelial cells in its host by pilli. This opportunistic pathogen can affect people of all ages and specifically targets patients that have immune deficiencies, debilitating diseases, and infants in the NICU. Patients are at greater risk of contracting the organism if they have recently had a surgery, mechanical ventilation, central venous catheter, arterial catheterization, inhalation medication therapy, tracheal tubes, or have low apgar scores. It can cause a variety of diseases and infections such as urinary tract infections, meningitis, pneumonia, respiratory tract infections, keratoconjunctivitis, osteomyelitis, keratitis, endocarditis, cutaneous infections, and endophthalmitis.

The next stage is called the pasture stage. The infective larvae move in moisture films by wriggling randomly onto the leaves and stems of pasture. Most of the larvae will die within 3 to 6 weeks as they do feed but survive on energy reserves, although they have the potential to live up to one year.

H. capsulatum is a dimorphic fungal pathogen that thrives in its mycelial phase in soil containing high concentrations of bird or bat guano, and every year hundreds of thousands of individuals who live in areas of endemicity are infected1,2. Though found worldwide, histoplasmosis is primarily a disease of North and Central America that is generally asymptomatic in healthy persons but may be fatal in immunosuppressed individuals2. Infection occurs by inhalation of small mycelial fragments or microconidia into the terminal bronchioles and alveoli of the lung. Inhaled conidia are phagocytosed by macrophages and the change in temperature from 250C to 370C induces the transformation into the yeast phase, which is responsible for the pathogenesis of histoplasmosis3–5.

Saporin S6 is a compound that was isolated from the Saponaria officinalis, a plant known as soapwart. It has been studied for almost thirty years due to its unique properties in medical science. It is a protein that has had many studies done testing its potential application towards anti-tumor and anti-viral therapy. This particular article describes the reasons for its high stability towards denaturing agents. Protein are susceptible to denaturalization under specific conditions like temperature or the chemical environment that it is in. A protein’s structure also contributes to its stability. Researchers are looking at all the properties of this specific protein that allows it to remain its folding structure and function under abnormal conditions.

Serratia plymuthica have received limited recognition with regards to their antimicrobial properties. Studies carried out on S.plymuthica have concentrated on the area of its pathogenecity in humans and animals. However, several reports have shown that S.plymuthica have the potential to secrete biocontrol agents against fungal pathogens. In this study, we looked at the antimicrobial production of a Seratia plymuthica strain that has the ability to inhibit various bacterial strains. The strain exhibits two phenotypic antimicrobial activities, one in the cells and the other in the supernatant. The antimicrobial compounds produced could be same or different to each other. Moreover, the compound is capable of inhibiting gram positive bacterial

The center for disease control (CDC) dates EHEC O157:H7 transmission to 1982.9 Its spread started with person to person contact and waterborne infection. Worldwide, incident rate ranges from 1 – 30 per 100,000 person with an increasing number of cases. About 73,000 persons are affected every year in the United States with about 67 death yearly 6.

Invasive mycoses may be categorized as i) opportunistic or ii) endemic. Endemic infections, which are generally confined to specific geographic regions, are most often acquired via inhalation of spores. Infective agents include, but are not limited to, Histoplasma capulsatum, Coccidioides immitis, and Blastomyces dermatitidis. These infections frequently mimic common pulmonary infections in initial stages and are therefore often misdiagnosed. Dissemination and advanced disease follow. Dormancy may also occur, with reactivation of infection years later. This leads to diagnosis in a geographic regions outside of the high risk area.(4, 5)

The analysis of the results by single type of mild stress (first analysis) as well as the analysis of the interactions (second analysis) indicates that the exposure to the OCC did not have a negative effect on the viability of Leuconostoc mesenteroides. In all the analysis performed by single type of mild stress (fist analysis) the same pattern was found; there were no significant differences between the negative and positive controls, low and medium levels of stress-agent within a given type of mild stress except for the highest levels of stress-agents which were significantly detrimental. In acid mild stress the survivability of Leuconostoc mesenteroides ranged from 103-63% the highest being the positive control and the lowest being exposure to pH 4.0 (Figure 4.1). Figure 4.2 shows that with the heat mild treatment no significant differences were found among both controls and all levels of mild heat stress (P > 0.05). The survivability ranged from 105- 100% (Figure 4.2). With ethanol, the survivability of Leuconostoc mesenteroides in the OCC was only different when exposed to 15% ethanol (v/v) (P < 0.05). The highest viability was obtained with the positive control which was 106% and the lowest with the 15% ethanol (v/v) with was 62%. (Figure 4.3). With the prior exposure to the oxidative stress, the viability in the OCC raged from 106-80% the highest being the positive control and the lowest being the 7.5 mM concentration of hydrogen peroxide which

Due to the remoteness of the affected area and the conditions for getting infected by the disease, the current outbreak does not represent a significant risk for

The treatment of Strongyloides depends on severity of the infection and the underlying host conditions (Miller et al., 2008).The goals of treatment for strongyloidiasis are to treat symptomatic disease and prevent complications in asymptomatic disease by eradicating the organism and thus eliminate autoinfection (Segarra-Newnham, 2007).To start with, traditional Chinese medicine (‘guan Zhong’, ‘gentian violet’) (Wang et al., 2013), Mebendazole (Reddy and Swarnalata, 2005), and tribendimidine (Steinmann et al., 2008) are the most widely used best treatment available for the uncomplicated infections. However, with advancing knowledge the current treatment options include thiabendazole, albendazole and ivermectin (Grove, 1996; Igual-Adell

Infection of Ascaris suum occurs when its eggs, containing a third stage juvenile, are swallowed. The eggs are able to survive on their own for so long because they are resistant to strong chemicals, low temperatures and dehydration (Abbasi et al. 2013). A.suum is found in pigs worldwide (Ballweber [Date Unknown]). Pigs infected with A.suum nematodes shows symptoms that include coughing or thumping, liver damage, impaired growth, and increased susceptibility to other infections (Miller et al. 2015).

However it is only present in cases with immunocompromised individuals or individuals who are undergoing corticosteroid treatment and those that are also infected with HTLV-1 (Luis A. Marcos et al., 2008; Alison C. Roxby et al., 2009).The symptoms of the disease may differ in acute or chronic phase. The acute phase generally begins within few minutes after the larva penetrates the host skin and is accompanied by redness and itchiness of the localized area at the point of penetration. Commonly seen symptoms within 24 hours of the larval penetration are edema, urticarial, and petechial at the site of penetration. In some cases, low grade fever, malaise and eosinophilia are also reported. Eosinophilia is usually prominent after one week of infection when the larva from the site of penetration reaches the lungs and the tracheobronchial pathway through portal system and starts irritating the throat which eventually results in severe coughing (Meyers et al., 2000).Feet is the common site of penetration (Meyers et al., 2000) and severity of the lesions depends on the number of larvae that penetrate the skin as well as the immune status of the infected individual. It takes normally three weeks for the infection to become chronic and larva resides in
