Nocardiosis in domestic ferrets (Mustela putorius furo).

Nocardia spp are ubiquitous, gram-positive, variably acid-fast, branching and beaded filamentous, facultative intracellular bacteria that are resistant to phagocytosis and can cause localized or systemic disease in a variety of mammals, including humans, as well as in birds, fish and reptiles. Seventeen pet domestic ferrets (Mustela putorius furo) were diagnosed with nocardiosis by several methods including cytological evaluation, histopathology, Ziehl-Neelsen staining and polymerase chain reaction (PCR). All except two ferrets were 2 years old or older at the time of clinical presentation.

Tropicoporus tropicalis: A Newly Recognised Pathogen in Eumycetoma and Refractory Mycoses in Humans.

Tropicoporus tropicalis (formerly Phellinus tropicalis) is a saprophytic basidiomycete that has been implicated in refractory mycoses in humans, particularly in patients with chronic granulomatous disease. Despite its clinical significance, T. tropicalis is an under-recognised cause of eumycetoma, with no prior reports available.

Molecular Detection of in Vaginal Swab Samples from Sheep That Aborted.

, an obligate intracellular bacterium, is the etiological agent of Q fever in humans and one of the causes of abortion in small ruminants. Although coxiellosis is considered an exotic disease, there are a few reports in Mexico. The objective of this work was to determine the presence of .

Polymerase Chain Reaction and Dot-Blot Hybridization for Leptospira Detection in Water Samples.

The dot-blot is a simple, fast, sensitive, and versatile technique that enables the identification of minimal quantities of DNA specifically targeted by probe hybridization in the presence of carrier DNA. It is based on the transfer of a known amount of DNA onto an inert solid support, such as a nylon membrane, utilizing the dot-blot apparatus and without electrophoretic separation. Nylon membranes have the advantage of high nucleic acid binding capacity (400 µg/cm), high strength, and are positively or neutrally charged.

Specific Detection of Uropathogenic via Fourier Transform Infrared Spectroscopy Using an Optical Biosensor.

Urinary tract infections (UTIs) are caused mainly by uropathogenic (UPEC), accounting for both uncomplicated (75%) and complicated (65%) UTIs. Detecting UPEC in a specific, rapid, and timely manner is essential for eradication, and optical biosensors may be useful tools for detecting UPEC. Recently, biosensors have been developed for the selective detection of antigen-antibody-specific interactions.

Tinea corporis intrafamilial infection in pets due to Microsporum canis.

Microsporum canis, one of the most widespread dermatophytes worldwide, is a zoonotic microorganism that transmits infection from reservoirs such as cats and dogs to humans. This microorganism is associated with Tinea corporis and other clinical manifestations; however, few studies have used genetic surveillance to determine and characterize the process of zoonotic transmission. In this study, we show a clear example of zoonotic transmission from a cat to an intrafamilial environment, where it caused Tinea corporis by infection with M.

Remarkable Phenotypic Virulence Factors of and Their Associated Genes: A Systematic Review.

is a widely distributed dermatophyte, which is among the main etiological agents of dermatophytosis in humans and domestic animals. This fungus invades, colonizes and nourishes itself on the keratinized tissues of the host through various virulence factors. This review will bring together the known information about the mechanisms, enzymes and their associated genes relevant to the pathogenesis processes of the fungus and will provide an overview of those virulence factors that should be better studied to establish effective methods of prevention and control of the disease.

Effects of vaccination with Brucella melitensis, strains Rev 1 ΔeryCD and Rev 1, on the reproductive system of young male goats.

The present study evaluates the effects of vaccination with Brucella melitensis strains Rev 1 ΔeryCD and Rev 1 on the reproductive system of male goats. Three groups, each of them consisting of 15 six-month-old brucellosis-free male goats, were studied. The first group was vaccinated with the Rev 1 ΔeryCD strain, the second group received Rev 1 and the third group was inoculated with sterile physiological saline solution.

Comparative genomic analysis of uropathogenic strains from women with recurrent urinary tract infection.

Introduction: Recurrent urinary tract infections (RUTIs) caused by uropathogenic are costly public health problems impacting patients' quality of life.

Aim: In this work, a comparative genomics analysis of three clinical RUTI strains isolated from bladder biopsy specimens was performed.

Materials And Methods: One hundred seventy-two whole genomes of urinary tract strains were selected from the NCBI database.

From Child to Old Man: A Slowly Evolving Case of Chromoblastomycosis Caused by .

Chromoblastomycosis is a chronic granulomatous mycosis of the skin and subcutaneous tissue caused by traumatic inoculation with dematiaceous fungi. This disease primarily affects agricultural workers, who are mostly men. We present a case of chromoblastomycosis in a 63-year-old male farmer patient with dermatosis over 50 years of evolution, with warty, erythematous, and scaly plaques that predominate on the left hemithorax.

Genome sequence of an strain obtained from a redlored parrot with pneumonia.

978-A_19 was obtained from a parrot with pneumonia. It is resistant to ampicillin, carbenicillin, cephalosporins, clindamycin, and trimethoprim + sulfamethoxazole. The genome encodes a new ADC allele, a OXA-502 gene, possesses several virulence genes related to adherence and biofilm formation, and has types I, II, and IV secretion systems.

Primary cutaneous mucormycosis due to Rhizopus arrhizus in an immunosuppressed patient with paroxysmal nocturnal haemoglobinuria.

Objective: We present a case of primary cutaneous mucormycosis in a patient with bone marrow failure secondary to paroxysmal nocturnal haemoglobinuria (PNH).

Clinical Case: A 60-year-old male patient with a history of PNH, complicated to a severe aplastic anaemia, presented to the emergency department complaining of papules on the lower limbs that rapidly turned into necrotic plaques within 2 months. Histopathological examination showed granulomatous and suppurative dermatitis with tissue necrosis and the presence of non-septate hyphae.

Effect of the JLM Strain Against Strains in Ripened Cheese.

This study evaluated the antagonistic effect of the JLM strain isolated from , against RB51, S19, and 2308 strains, during the manufacture of soft-ripened cheese.

Unexpected Presence of Blastocystis Subtype 1-3 DNA in Human Vaginal and Sperm Samples Coinfected with Trichomonas vaginalis.

There have been few reports on extra-enteric infections by Blastocystis STs and none have been molecularly identified in samples from human reproductive organs. We report for the first time the identification of 3 different subtypes of Blastocystis (ST1-3) in vaginal and sperm samples, from patients infected with Trichomonas vaginalis. Blastocystis STs were identified by PCR-sequencing and by phylogenetic inferences using 28 vaginal swab samples and 7 sperm samples from patients trichomoniasis.
