Rotavirus stability and inactivation.
Estes MK, Graham DY, Smith EM, Gerba CP. Estes MK, et al. J Gen Virol. 1979 May;43(2):403-9. doi: 10.1099/0022-1317-43-2-403. J Gen Virol. 1979. PMID: 39115
SA11 infectivity was stable to freeze-thawing, sonication, incubation at 25 degrees C overnight or at 37 degrees C for 1 h and to treatment with acid, ether, chloroform and Genetron. In contrast to reovirus, the infectivity of SA11 was more rapidly inactivated by he …

Numbers of individual nutrient germinant receptors and other germination proteins in spores of Bacillus subtilis.
Stewart KA, Setlow P. Stewart KA, et al. J Bacteriol. 2013 Aug;195(16):3575-82. doi: 10.1128/JB.00377-13. Epub 2013 Jun 7. J Bacteriol. 2013. PMID: 23749970 Free PMC article.
The total lysate from disrupted wild-type spores contained 2,500 total GRs/spore: GerAA and GerAC subunits each at 1,100 molecules/spore and GerBC and GerKA subunits each at 700 molecules/spore. Levels of the GerBA subunit determined previously were also predicted to be 70 …

Virucidal efficacy of laundry sanitizers against SARS-CoV-2 and other coronaviruses and influenza viruses.
Khalid Ijaz M, Nims RW, McKinney J, Gerba CP. Khalid Ijaz M, et al. Sci Rep. 2022 Mar 28;12(1):5247. doi: 10.1038/s41598-022-08259-0. Sci Rep. 2022. PMID: 35347149 Free PMC article.
Efficacy was measured in terms of log(10) reduction in infectious virus titer, after 15 min contact time (suspension studies) or 5 min contact time (hard surface studies) at 20 1 C. In liquid suspension studies, laundry sanitizers containing p-chloro-m-xylenol (PCMX …

Interaction between individual protein components of the GerA and GerB nutrient receptors that trigger germination of Bacillus subtilis spores.
Igarashi T, Setlow P. Igarashi T, et al. J Bacteriol. 2005 Apr;187(7):2513-8. doi: 10.1128/JB.187.7.2513-2518.2005. J Bacteriol. 2005. PMID: 15774895 Free PMC article.
Germination of Bacillus subtilis spores via the GerA nutrient receptor was suppressed by GerAC lacking the diacylglycerylated cysteine essential for receptor function. Overexpression of the C protein of the GerB nutrient receptor also suppressed the function of both the Ge …

Virus removal during simulated soil-aquifer treatment.
Quanrud DM, Carroll SM, Gerba CP, Arnold RG. Quanrud DM, et al. Water Res. 2003 Feb;37(4):753-62. doi: 10.1016/s0043-1354(02)00393-7. Water Res. 2003. PMID: 12531257
Increasing reactor detention time from 5 to 20 h increased coliphage attenuation from 70% to 99% in a 1-m sand column. There was a significant linear correlation (p=0.012) between log-transformed (fractional) coliphage concentration [log(C/C(0))] and reactor …
