Clinical isolates of Mycobacterium simiae in San Antonio, Texas. An 11-yr review.

During a period of 11 yr (1983-1993) 137 clinical isolates of Mycobacterium simiae obtained from 75 patients were identified in a University hospital in San Antonio, Texas. One hundred twenty-eight isolates (93%) were from a pulmonary source, four (3%) from blood, and five from other sites including skin, urine, lymph node, bone marrow, and brain. Of 62 evaluable patients, six (10%) had definite infection, nine (14%) had probable disease, and 48 (76%) were thought to be colonized. During the last 2 yr of the study (1992 and 1993), M. simiae became the second most frequently isolated nontubercu…

Vitamin A levels of blood in collared peccaries (Tayassu tajacu) from south Texas.

Serum vitamin A concentrations were determined for 24 adult female collared peccaries from 1 captive and 2 wild populations during the period 30 January-15 March, 1983. Normal serum vitamin A concentrations of well-fed captive peccaries (mean = 39.0 micrograms/dl) were slightly higher than the reported range of values for domestic swine. Mean vitamin A concentrations of blood serum did not differ among the captive and 2 wild populations. However, a few individuals from the wild populations had low serum levels of vitamin A which suggested a possible vitamin A deficiency for these females.

Exploring Condom Use Among Adult Cisgender Black Women in Texas: a Qualitative Analysis.

BACKGROUND: Cisgender Black women (CBW) remain disproportionately affected by HIV in the United States. Condoms, when used consistently and correctly, are an effective and reliable method for reducing acquisition and transmission of HIV and other sexually transmitted infections (STIs). However, consistent condom use among CBW is mixed. This study aimed to garner a contemporary conceptualization of factors impacting condom use among CBW with male sexual partner(s) residing in large urban areas in Texas. MATERIALS AND METHODS: Between December 2020 and January 2022, CBW (N = 154) were recruited …

Independent Discovery of Mesomycoplasma conjunctivae in Non-Native Aoudad (Ammotragus lervia) in Texas.

Conservation of native species is an ongoing task, especially when non-native species present a threat via competition and disease transmission. In Texas, native desert bighorn sheep (DBS) compete directly with non-native aoudad for resources. Aoudad (Ammotragus lervia, also known as Barbary sheep), introduced into the United States from Africa, are competent hosts of Mesomycoplasma ovipneumoniae and are thought to be the primary reservoir for transmitting pneumonia to DBS. A recent epidemic (circa December 2025) of infectious keratoconjunctivitis (IKC) in aoudad was reported in western Texas.…

Creutzfeldt-Jakob Disease in South Texas: A Case Series of Three Hispanic Patients.

Creutzfeldt-Jakob disease (CJD) is a rare, rapidly progressive neurodegenerative disorder instigated by the pleating of prion proteins. Most cases are sporadic, with no identifiable genetic or environmental trigger. This retrospective case series aims to bridge the current knowledge gap in regard to CJD in Hispanic populations. We hope to review the management and outcomes of three Hispanic patients diagnosed with sporadic CJD at a community hospital in South Texas between 2021 and 2024. Clinical data, imaging studies, and cerebrospinal fluid (CSF) results were reviewed for three unrelated pat…

Organ Donor Transmission of Rickettsia typhi to Kidney Transplant Recipients, Texas, USA, 2024.

Murine typhus, a fleaborne disease caused by the bacterium Rickettsia typhi, is found throughout temperate and tropical regions of the world. Transmission of R. typhi to humans involves several species of fleas, and most infections result from direct inoculation of R. typhi-infected flea feces into abrasions in the skin. We describe the transmission of R. typhi from an organ donor in Texas, USA, to 2 kidney transplant recipients. The donor and 1 recipient died from the infection. The occurrence of R. typhi transmission via transplantation is a harbinger for the reemergence of murine typhus in …
