66-year-old female patient presents palpebral bilateral ptosis and external ophthalmoplegia with a progressive evolution. The clinical aspects are completed with the affectation of the sensitive and motor trigemen, with the masseter atrophy and bilateral trophic keratitis. The affectation of the facial and acoustic nerves was associated with bilateral perception surditate. The hereditary transmission was dominant, with incomplete penetration. The neurogenic pathogeny was sustained on the basis of the association of neurological multilesions with III, IV, V, VI, VII, VIII nerves, with progressive extension.

Herpes simplex virus type 1 (HSV-1)-related disease ranges from a localized, self-limiting illness to fatal disease in immunocompromised individuals. The corneal disease herpetic keratitis may develop after reactivation of a latent virus or reinfection with an exogenous herpesvirus. Molecular analysis of the virus involved may allow distinction between these two options. The HSV-1 genome contains several hypervariable regions that vary in numbers of reiterating regions (reiterations I to VIII [ReI to ReVIII]) between individual strains. Twenty-four HSV-1 clones, derived by subcloning of HSV-1 (strain F) twice in limiting dilutions, were tested in a PCR-based assay to analyze the stabilities of ReI, ReIII, ReIV, and ReVII. ReI and ReIII proved to vary in size upon subcloning, whereas ReIV and ReVII were stable. Subsequently, 37 unrelated isolates and 10 sequential isolates from five patients, all with HSV-1-induced keratitis, were genotyped for ReIV and ReVII. Of the 37 unrelated samples, 34 (92%) could be discriminated, while the genotypes of the viruses in sequential samples were identical for each individual. Conclusively, the data show that the approach presented allows the rapid and accurate discrimination of HSV-1 strains in studies that address the transmission and pathogenesis of HSV-1 infections.

Multidrug-resistant (MDR) Pseudomonas aeruginosa VRFPA04, obtained from a keratitis patient was found to exhibit resistance to betalactam (Penicillins, cephalosporins, including carbapenems, except aztreonam), aminoglycosides, quinolone group of drugs and susceptible to colistin. The complete genome sequencing of the ocular isolate to measure and ascertain the degree of multidrug resistance in VRFPA04 strain resulted in 6,818,030bp (6.8Mb) genome sizes, which happen to be the third largest genome available in the Genbank to date. Two chromosomally integrated class I integrons carrying blaVIM-2 carbapenemase gene, multiple secretory systems consisting of types I-VI and VIII proteins and ocular virulence factors exo-T, Y, U and exotoxin A, a gene that inhibits protein synthesis which could have caused corneal cell death and Phytohormone auxin biosynthetic protein were detected in the genome of VRFPA04 Genome. In addition, 58 Regions of Genomic Plasticity (RGPs) regions, multiple phage genomes, genomic islands, CRISPR genes and RND family efflux pumps, such as MexCD-OprJ and MexEF-OprN and its regulators, MexT and MexR, were unraveled in VRFPA04. Thus, the current study reveals the virulence factors and resistome nature of an ocular isolate P aeruginosa VRFPA04 genome.
