New study of #mpox clade IIb in Nigeria during the 2022 outbreak: • Mpox primarily affected young adult males. • Risk factors included close contact with a person with confirmed mpox, risky sexual behavior, and animal exposure. bit.ly/4dKmDBL

New study demonstrates that transfusion-relevant bacteria can produce #biofilms in platelet storage bags. If biofilm formation causes evasion of bacterial testing or pathogen reduction, several questions remain for further investigation. bit.ly/3YSDMF4

A #rustrela virus variant was identified in a wild mountain lion in Colorado. The animal had clinical signs and histologic lesions compatible with staggering disease. bit.ly/4ddiwhC

#H5N5 and #H5N1 viruses isolated from crows in Hokkaido, Japan, during winter 2023-24, shared genetic similarity with HPAI H5N5 viruses from northern Europe but differed from those in Asia. bit.ly/3M5aQCj

#SARSCoV2 was found by PCR (2/22, 9.1%) and by culture (1/22, 4.5%) in skull sawdust, suggesting that live virus is present in tissues postmortem, including bone. Occupational exposure risk is low with appropriate personal protective equipment. bit.ly/3LOaX4U

A study of #SARSCoV2 and #inflenza rates in childcare centers and schools in China during Feb-June 2023 estimated, approximately, an overall infection rate of 125 and 128 per 1,000 people for SARS-CoV-2 and influenza. bit.ly/4fNxe0Q

Researchers detected #influenzaA virus host receptors in bovine mammary glands by histochemistry. Results provide a rationale for the high levels of H5N1 virus in milk from infected cows. bit.ly/46QJiKI

New study on detection of Crimean-Congo hemorrhagic fever virus in serum, saliva, and urine samples found that serum is the best sample type for #CCHF diagnosis; saliva can be used for noninvasive sampling. bit.ly/4dmoSep

Findings from #mpox samples collected May–September 2022 in Italy suggest that close or skin-to-skin contact during sexual intercourse is the main route of sexual transmission and that semen is a minor driver of infection, regardless of MPXV load. bit.ly/3SPQW1S

A #Leptospira venezuelensis outbreak circulating in rodents appears to have spread to cows in La Guaira State, Venezuela and also infected people, in whom it might have caused febrile illness with hepatic involvement. bit.ly/3WGophF

New podcast episode: Dr. Mihnea "Mike" Mangalea, a microbial ecologist and bioinformatician at CDC, and Candice Hoffmann discuss decolonization and pathogen reduction approaches to prevent #AMR and healthcare-associated infections. Listen online at bit.ly/3WZBIbU

😯 There is still so much to learn on global public health!! An unexpected second endemic CL/MCL agent in Sri Lanka! In this EID journal paper Hermali Silva and I report an undescribed #Leishmania lineage in SL. Not L.donovani! wwwnc.cdc.gov/eid/article/30… NIAID News University Colombo

#Influenza D virus was isolated from pigs on a mixed pig and beef farm in France. Investigation suggested bull-to-pig transmission and spread among pigs. bit.ly/3Sr9rJQ

#ParasiticDiseases is the September theme for EID journal. You can read the articles and see this month’s cover image, On the Trail by Winslow Homer (1836–1910), online now. bit.ly/3sF44cR

A woman became infected with #Naegleria fowleri from an indoor surfing center in Taiwan. She was hospitalized with fever and generalized tonic-clonic seizures and died 3 days later. bit.ly/4dGee2x

Severe #babesiosis with 9.8% parasitemia was diagnosed in a patient in the Netherlands. Babesia venatorum was confirmed via PCR and sequencing. bit.ly/3XoCRew

Pneumocystis jirovecii #pneumonia is an opportunistic infection that affects HIV-infected and immunocompromised people. Since the COVID-19 pandemic, some COVID-19 patients without immunocompromise or HIV were infected with P. jirovecii. bit.ly/4dYF3yO

A #Thelazia callipaeda eyeworm was found in an American black bear in Pennsylvania. This finding highlights the emergence of a T. callipaeda worm sylvatic transmission cycle in the United States. bit.ly/3MpdzXn

Taenia solium (pork #tapeworm) was found in a child in Timor-Leste, suggesting T. solium transmission to humans is occurring in the country. bit.ly/3z17ugO

A Hungarian man who experienced fever, nausea, vomiting, and weight loss was diagnosed with autochthonous human #babesiosis. Babesiosis should be considered during the differential diagnosis of febrile illnesses. bit.ly/4g5NyKj
