Fungal spores are ubiquitously present in the air. Inhalation of these spores by humans causes disease in susceptible patients; most prevalent are invasive aspergillosis and allergic bronchopulmonary aspergillosis (ABPA). This chapter provides an overview of the pathogenecity, clinical appearance, diagnosis and treatment of ABPA. ABPA is a hypersensitivity lung disease limited to patients with ...

Human health is threatened by various infectious bacterial pathogens but is also supported by many commensal bacteria particularly in the intestinal tract. However, many of the bacterial pathogens and commensal bacteria are taxonomically indistinguishable, with pathogenic and commensal bacteria existing in the same genus and even species. A typical example is Escherichia coli, which is commonly...

BACKGROUND Fusarium oxysporum has worldwide distribution and causes severe vascular wilt or root rot in many plants. Strains are classified into formae speciales based on their high degree of host specificity, of which multilocus sequence typing provides a fairly good estimate. AIMS The main aim of this study was to identify the causal agent of an infected potato tuber in Colombia. METHODS ...

Myroides sp. are gram negative aerobes and known for its oppurtunistic pathogenicity in humans. In the present study, Myroides odoratimimus isolated from the gut of Mugil cephalus showed potential infectivity to the experimental grey mullet and acted as an ultimate pathogen with significant symptoms. Furthermore, the inoculum isolated from the infected fishes were cultured and the selected colo...

Characterization of isolated pigeon paramyxovirus-1 (PMV-1) and its pathogenicity in broiler chickens were studied. Two hundred and thirty-two samples collected from 50 unvaccinated pigeons lofts suspected to Newcastle disease from private houses and bird markets from Ahvaz, Iran. Swab samples from cloaca and oropharynx of live pigeons and from trachea, lung, liver, spleen, kidney, brain, prove...

Invulnerability of Mycobacterium tuberculosis to various drugs and its persistency has stood as a hurdle in the race against eradication of the pathogenecity of the bacteria. Identification of novel antituberculosis compounds is highly demanding as the available drugs are resistant. The ability of the bacteria to surpass the body's defenses and adapt itself to survive for disease reactivation i...

Within the last 15 years, several bacteria of the genus Bartonella were recognized as zoonotic agents in humans and isolated from various mammalian reservoirs. Based on either isolation of the bacterium or PCR testing, eight Bartonella species or subspecies have been recognized as zoonotic agents, including B. henselae, B. elizabethae, B. grahamii, B. vinsonii subsp. arupensis, B. vinsonii subs...

HIV-1 envelop gene is a major target for vaccine development. Envelop protein and its V3 loop is shown to be important determinant of HIV-1 pathogenecity. Herein, the evolutionary pattern of most prevalent HIV-1 subtype B in Asia is determined by analyzing envelop protein and V3 domain based on the 40 randomly selected sequences of HIV-1 from database (Los Alamos), divided into four groups sinc...

Characterization of the helminth parasites of wild fish has a considerable importance from the point of view of hygiene and public health, as well as from its taxonomic interest. To study the pathogenecity of parasites in the field of fisheries, require detail knowledge of the parasites inhabiting localities involved. Present study aimed to investigate the intestinal nematodes from the Puntius ...
