First Report of Sorghum Ergot Caused by Sphacelia sorghi in Mexico

Sugary disease or Asian ergot of sorghum - Claviceps sorghi

Claviceps sorghi is a pathogen of Sorghum bicolor found only in India and Southeast Asia. The more widespread C. africana is predominant even in India; C. sorghi appears to be marginalized in its restricted range. A significant difference in invasiveness is the relative production of inoculum that spreads plant-to-plant. Claviceps sorghi produces few to no secondary conidia from macroconidia on...

Cultural characteristics, morphology, and variation within Claviceps africana and C. sorghi from India.

Sorghum ergot in India is caused by Claviceps africana and C. sorghi. The distributions of these two species in India is not known. Eighty-nine sorghum ergot isolates were cultured from young sphacelia obtained from male sterile sorghum plants artificially inoculated using inoculum collected in the field. Based on cultural characteristics, the isolates were separated into two groups which diffe...

Case Report of Meningoencephalitis in Calves Caused by Escherichia coli

First report of Staphylococcal clinical isolates in Mexico with linezolid resistance caused by cfr: evidence of in vivo cfr mobilization.

An oxazolidinone resistance mechanism (Cfr) was recently described in human isolates of staphylococci (18). Cfr causes posttranscriptional methylation of the 23S rRNA (A2503), affecting drugs belonging to several antimicrobial classes (10). cfr-carrying isolates recovered from human clinical specimens are still rare (4, 6); however, cases were reported in the United States (12), Colombia (18), ...

First case report of pulmonary nocardiosis caused by Nocardia mexicana

INTRODUCTION Nocardia species usually cause opportunistic infections, and the frequency of these infections is increasing owing to the growing population of immunocompromised hosts. However, Nocardia species may sometimes cause an infection disease in immunocompetent hosts. Nocardia mexicana infections are the least common and are very rare. CASE PRESENTATION Herein, we report the first case ...
